Delighted that my etching Forest of Eden has been selected for exhibition at AIR Gallery on the theme of the macabre with the exhibition renamed Memento Mori. What happens when we are confronted with the uncomfortable or visually grotesque? What makes the unappealing difficult to digest but impossible to turn away from?

The myth of the wild man stretches back to the tale of Gilgamesh’s quest for immortality.  In history the wild man’s characteristics oscillate between horror and fantasy. They reflect fear of the other as well as aspirations to be at one with nature often violating the taboos of civilization and symbolizing the repressed desires of society. This person who posts photos of himself in charged poses has become an internet meme shared with equal disgust and fascination. In this etching he is placed back in the ancient forest of all our origins.

I have completed the video commission Cosmic Chiasmus (crossing the universe) for Queen’s Hall Digital but am continuing research into cosmic rays. Around 10,000 muons rain down on each square metre of Earth’s surface every minute.

Muon tomography can be used to remotely explore dense matter for hidden voids. High energy cosmic rays such as muons pass through objects, but in doing so, some will be absorbed by the object and so fewer particles will arrive on the other side. This means sensitive muon detectors can be used like x-rays to determine the structure of extremely large and dense objects. This method has been used to reveal a mysterious, 30-metre-long hidden chamber in the 4,500-year-old great pyramid of Giza, to determine the inner structures of volcanoes and to study the damaged nuclear reactor at Fukushima, Japan.

I have discovered an audio manipulation in Adobe Audition that makes my own voice acceptable to me as voiceover for my video work. So I have returned to the video Contingent Horizons, rewritten and recorded new dialogue.

This dialogue is based on the excerpts from popular online lectures that I had used before but I have reimagined some of these quotes and included ideas from ancient descriptions of the cosmos.

Out of the studio:

Lisa Chang Lee Symphony Zero at San Mei Gallery. Beautiful work creating a fragile connection between humans and the natural world as rhythms coincide to create collaborative music. Plants swaying in the breeze are each represented by a musical instrument sympathetic to its form and its movement is transposed using algorithms applied using modes of symmetry and interval into musical scores which in turn are played by humans.

Less a building: Interactions with the London Zoo Aviary book launch hosted by Passengers at The Brunswick Centre. Transported by readings from the book of this iconic flight of fancy in architecture for avian captives at the zoo. A many layered and collaborative research project by Michaela Nettell with Marcela Araguez, Tim Dee, Polly Gould, Alex Hartley, Julie F Hill, Helen Jukes, Milena Michalski, Colin Priest, Ana Ruepp and Matthew Turner. Excellent writing and gorgeous artworks. Now I wish I’d visited the aviary more often.

Geographies of Print collective Without Horizon, Without Shore. Stunning installations set against the civic backdrop of the Old Lambeth County Court, an apt setting for work looking at passage of time, capturing the transient and the human condition.

Victoria Arney has used the sonograms of bird song to create sculptural woodcuts. Capturing fleeting moments within landscape.

Victoria Ahrens looks at erosion and disappearance, creating work in situ using the minerals present in the landscape to hand colour her prints. We think of colour as light bouncing off matter, some absorbed, some reflected, but this work really brings home how integral colour is to substance.

Carol Wyss uncovers the structures that shape us physically and bear witness human frailty.

Symbols made from bones connect us to the earth as origin and destiny.

Thom Bridge Only Similar or Equivalent at Best solo show at Staffordshire Street Studios. Incredible work with light taking the image into realms of physics and geology.

“The degree to which an image is like the world is a question not of fidelity- as a narrative of documentation or technological development would have it – but of equivalence, the role that an image plays in showing in showing, or demonstrating, representing or bringing into view. Equivalence takes priority over resemblance, because the task of the image is not to repeat the world, but to inform it, and by informing it, subtly alter it in turn.” Duncan Wooldridge

Chudamani Clowes in Figure It Out with the Neulinge Collective. Wonderful immediacy as always from Chud that cuts right through to expose the lived experience of those who migrate. Epic journeys bring stories and transformation. The coral is on the move.

Robert Good in Osmosis: experiments in permeability at Espacio Gallery with work that forces an examination of an addiction to media updates, digital clickbait and daily data news dumps. Assaulted by a tsunami of inane questions and disconnected headlines into a brain numbing torpor the need for space to think is made apparent.

A captivating telling of how magic is vital for our well being and should be sought not shunned. Mythosphere is a multi-media theatre production created by Inna Dulerayn presented by Bacchae productions in partnership with Stone Nest at the atmospherically derelict Old Welsh Chapel on Shaftesbury Avenue. Inspired by the life experiences and creativity of Leonora Carrington and the writings of Diana Wynne.

This is a story about magic. The magic that we lost. The magic that is a forgotten part of our nature. The magic that is our right to be divine. But we still sense it. We dream of it. We feel abandoned without it. We keep looking for it all our lives.

Reading:

I am still dipping into The Waves by Virginia Woolf which I was inspired to read after listening to the Art Fictions Podcast with guest artist Hannah Hughes speaking to Fiona Fullerton. I particularly love the interludes as the sun rises over the ocean and begins its journey across the sky. Like too rich chocolate cake the intensity of Woolf’s writing is delicious but can only be taken in small bites.

I have Chantall Powell to thank for flagging up the book The Philosophers’ Secret Fire: A History of the Imagination by Patrick Harpur. A fascinating book taking the view that just because something is not literally so doesn’t mean it isn’t ‘real’. As in Mythosphere the book seeks to rediscover the Otherworld of spirits, gods and daimons which the west has banished to the unconscious mind.

I was so excited to read the following:

“…daimons inhabit another, often subterranean world which fleetingly interacts with ours. They are both material and immaterial, both there and not-there – often small, always elusive shape-shifters whose world is characterized by distortions of time and space and, above all, by an intrinsic uncertainty.

The point is: the words ‘subatomic particles’ could be substituted for ‘daimons’ in the paragraph above without any loss of accuracy. This is not a coincidence – the subatomic realm, like the unconscious, is where the daimons took refuge once they were outcast from their natural habitat.”

When cosmic rays smash into the nuclei of gases high up in the atmosphere a variety of secondary particles are created but the only ones typically long-lived enough to make it to the Earth’s surface are muons. Muons are heavy electrons with a lifetime of 2.2 millionth of a second before they decay into an electron and a neutrino. Muons are typically produced around 15 km up in the atmosphere, a distance which takes around 50 millionths of a second to cross at the speed of light. This is over 20 muon lifetimes so they shouldn’t be able to get to Earth’s surface before they decay. However, since they are travelling approximately 98% the speed of light, time in their frame of reference is significantly stretched relative to time we experience on Earth. This means that they can travel much further in a shorter period so many Muons do make it to the surface. Special relativity is mind boggling.

Particles that arrive on Earth can cause computer processor bits to flip from one to zero or zero to one. The larger the computer is and the higher the altitude where it operates the more data corruption can occur. There are procedures to enable high altitude supercomputers like those at Los Alamos National Laboratory, birthplace of the atomic bomb, to detect when a bit is flipped and raise an alarm to force a crash and system reset. The big problem is silent corruption that neither the computer or human notices that could occur in sensitive data such as nuclear weapons stewardship and modelling for national security, space exploration, climate change, disease transmission, new drug trials etc.

This is all research and stills from my video commission Cosmic Chiasmus for Queen’s Hall Digital which will be going live soon.

Further work on sculptural piece 90 light years home joining all the individual tiles to make raster patterns of fragmented data transmissions. Made from a combination of screen print on textile, dye sublimation print and chinagraph pencil.

These are scrambled messages to outer space. This work is based on the raster patterns of the first TV signals when images were transmitted in a series of lines. It is a systematic process of covering an area progressively, one line at a time. It is similar to how one’s gaze travels when one reads lines of text. 

HD 70642 is a star about 90 light years away. It has roughly the same mass and radius as our sun. It has a companion planet that orbits in a circular motion very similar to how the planets orbit in our solar system. Waves like FM radio or television signals can pierce the ionosphere and travel through space at the speed of light. The first radio and TV signals from Earth will be reaching this solar system about now.

The work for my planned cosmic ray detector interactive artwork is still at the sourcing components stage. I am gradually gathering many small packages containing mysterious miniscule parts with worrying warning labels. No mention of the handling precautions in the HOW TO video! Also certain items seem to be difficult to get hold of at the moment with shipping dates set to next spring.

I have sent off for the custom printed circuit boards from China with fingers heavily crossed.

The detector works on the basis that when a charged particle passes through a scintillating material, part of its energy is absorbed and re-emitted as photons. A light sensitive device called a silicon photo-multiplier (SiPM) coupled to the scintillator observes these photons. A single photon can make a measurable signal in the SiPM and can be amplified to shape the signal in such a way that it can measure both how many photons were observed and at what time they arrived using an Arduino Nano. I am hoping to divert that signal to set off a script controlling a layering of on screen images which generatively decay as each cosmic ray pulse is recorded.

In 2019 for the exhibition Reading Stones I created the site specific installation Time Crystals in the ancient St. Augustine’s Tower in Hackney. The nature of time itself was a concept that St Augustine of Hippo grappled with in his philosophical texts sixteen centuries ago and is still perplexing us today; namely, how to equate the subjective experience of time with an objective understanding.

In the news recently is the actual realisation of time crystals, a wholly new phase of matter to add to solids, liquids, gases and plasma that we are familiar with. Solid crystal structures repeat patterns across space whereas time crystal patterns repeat over time. Google researchers in collaboration with physicists at other universities have used Google’s quantum computer to produce this special phase of matter that changes constantly between states, but doesn’t appear to use any energy. All other known phases of matter are in thermal equilibrium meaning their their properties don’t change with time if the temperature is constant and settle into a low energy ambient state. Electronic computers use the binary system of 1s and 0s, on or off to process data. In a quantum computer, quantum bits have more possible states than just on and off adding uncertainty to outcomes. Qubits are unstable, acting differently when they’re under observation but time crystals remain stable while constantly flipping states and may be a huge breakthrough for complex computing and data modelling.

Pleased to announce work has finally been installed through Dais Contemporary at the impressive new Taj St James Court Hotel. Two screen print pieces from the everydaymatters series which are informed by the percentages of visible matter, dark matter and dark energy in the universe, and C-type on aluminium Pairi Daêza based around the refencing by Plato of the dodecahedron as the Aether holding the stars in the heavens. Dissecting landscapes to discover the hidden structures of the universe.

Expanding my etching skills with photopolymer process under the expert eye of J. Yuen Ling Chiu. It’s all in the inking up. Ling is such a great teacher.

Trying more new skills with a Super 8 workshop run by knowledgeable enthusiast Ben Slotover who packed a lot into one day. I really enjoyed trying the different cameras and the dreamlike spattered effects of the final films. Definitely something I want to try again though I think there will be lots to learn to achieve good results. I think it might work well to revisit my paradise works with this medium. The nostalgic ethereal quality appeals for this especially with the expired Kodak film as this needs to be flooded with light to work well.

Enjoyed the super/collider hosted zoom presentation Finding Asteroids with Dr Maggie Lieu research fellow in Machine Learning and Cosmology at the University of Nottingham. As of April 2021, there are over 25,000 near-Earth objects and many of these are a potential risk to life here on Earth, but in the main asteroid belt between Mars and Jupiter, there is believed to be over 2 million asteroids, some of which can reach 1000km in size! Scientists are actively searching for new, and tracking known asteroids. Often, they won’t know for sure where an asteroid will hit or how big an impact it will make until a few days before the collision. Machine learning is being used to keep a look out for potentially hazardous asteroids heading towards Earth. Interesting to hear how cosmic rays interfere with the data searches for asteroids by mimicking the traces made by asteroids but at such a different scale.

I joined Aphra Shemza for her online digital painting and co-creating workshop. The workshop was great fun, centered around the shemza.digital project which is a collaboration with computer artist Stuart Batchelor. Shemza.digital is based on the work of Aphra’s grandfather, the well-known British/Pakistani painter Anwar Jalal Shemza. It was inspiring and at times shocking to hear the family history and his struggle for recognition against the racism of the institutions he came into contact with as a young art student at the Slade and beyond.


Rewarding visit to Night Shaking with The Ingram Collection at The Lightbox, Woking. A spinetingling collection of objects dredged from the subconscious on a Night Sea Journey accompanied by enlightening and poetic text

“On the ‘Night Sea Journey’, what we think we know is held up to be an illusion. Our minds cannot fully grasp the changes of consciousness that take place during this ordeal. Ego and persona are forced to give way. This difficult inner terrain holds within it a hidden potential to experience a dramatic transformation of consciousness”

Objects and paintings made by Chantal Powell and Dean Melbourne are brought together with chosen artefacts from The Ingram Collection as the artists draw us into the Dark Night of the Soul and the Night Sea Journey narrative.

Chantal talking here on the symbolism of crowns and boats in alchemy and transformation.

We are made of carbon, it is the basic building block in virtually every cell in our body. Most of the carbon in the world is carbon-12 which contains six neutrons and six protons. However about 15 km above our heads radioactive carbon-14 is formed as neutrons from cosmic rays interact with the atmosphere.

Protons and atomic nuclei created by events such as exploding stars speed across space and collide violently with the Earth’s atmosphere creating a chain reaction of cascading particles. Some of these tiny travellers may come from distant galaxies or be created by phenomena that we are yet to discover. Our body is continuously permeated at a subatomic scale by these particles fired into our world – an almost tangible contact with outer space.

Carbon-14 has six protons and eight neutrons and has a half-life of 5,730 years. This means that after 5,730 years dead matter which absorbed Carbon-14 when alive will contain half the amount it had when it died and after another 5,730 years that amount will have halved again. Radioactive decay is random but in a sample there are enough atoms to work out an average time it will take for the nucleus to lose the extra neutrons.

This radioactive carbon-dioxide in the atmosphere is absorbed by plants which are eaten by animals and humans.

Cosmic ray activity gives us carbon dating techniques.

I am working on a video, Cosmic Chiasmus, meaning crossing.

Plant time lapse filming is fascinating to see how plants are so animated just at a different time scale to us. Also I have recently finished reading Richard Powers Overstory, a very powerful sobering read, which celebrates the slow yet socially active time of trees.

At Coniston. We are left to imagine the past majesty of this ancient giant which was lopped so it didn’t drop branches on the cars in the carpark.

Carbon dating is performed by measuring Carbon-14 in organic matter. Radiocarbon decays slowly while an organism is alive but is continually replenished as long as the organism takes in air or food.

When an organism dies no more Carbon-14 is absorbed and that which is present starts to decay at a constant rate.

By measuring the radioactivity of dead organic matter, the current carbon-14 content can be determined and the time of death established.

The oldest matter that can reliably be carbon dated is about 50,000 years old. Currently techniques are being refined as they have often relied on the assumption that Carbon-14 levels in the atmosphere are constant but they are not.

The burning of fossil fuels which have lost all their radiocarbon dilutes the amount of Carbon-14 with carbon dioxide and nuclear explosions add huge amounts of ‘bomb carbon’ to the atmosphere. During planetary magnetic field reversals more solar radiation cosmic rays enter the atmosphere producing more Carbon-14. Also the oceans suck up carbon circulating it for centuries.

There are a number of uncertainties for dating shell.

On the surface of the earth two to three Muons pass through your hand every second, underground this is reduced to about once a month.

I collected a selection of images from the 1930’s including some from family, including my Mum aged 3, which I have tinted blue and had printed on sublimation dye paper for transfer to the tiles making up the raster pattern in the work in progress 90 Light Years Home. FM radio and television signals can pierce the ionosphere and travel through space at the speed of light. The first signals will have travelled about 90 lightyears now to arrive at a solar system very similar to our own. Fragments travelling through space for light years with the potential for alien life to decipher.

While searching for images to use as fragments of our world as it appeared about 90 years ago in old National Geographic magazines I came across some articles about balloon voyages in the 1930’s to the stratosphere to record cosmic ray activity.

Intrepid explorers. These early explorations were innovative but also dangerous. In July 1934 a flight developed tears in the balloon fabric at about 57,000 feet and began to break apart, as it did so the hydrogen in the balloon exploded and the crew had to parachute to safety.

Physicist Victor Hess had already made a series of daring ascents in a balloon to take measurements of radiation in the atmosphere. In 1912 he made an ascent to 17,000 feet during a near-total eclipse of the Sun to determine if the source of the radiation was coming from the Sun and made the discovery that it had to be coming from further out in space.

The stratosphere balloon Explorer II was designed to carry heavy instruments for cosmic ray measurements to a height of 13 miles and more above sea level.

Scientists designed a system of cosmic ray telescopes to record the numbers of cosmic rays coming in from several angles above the horizon. Most of the cosmic rays counted are secondary particles shot out from the atoms of the air by the primary rays entering and colliding from space. During this flight the height at which most secondary cosmic rays are produced was determined and the first records of bursts of energy from atom disruption by cosmic rays was made.

Also, the first track ever made directly in the emulsion of a photographic plate by an alpha-particle cosmic ray with enormous energy of 100,000,000 electron volts was achieved. Two boxes of photographic plates coated with special emulsion were wrapped in light tight paper and attached to the balloon gondola. When the plates were developed there were no visible images but when put under a microscope tracks could be seen where the particles had ploughed through the emulsion.

Early google earth. They also took the highest altitude photographs of the Earth ever made.

To record data they had a series of cameras set to take automatic photographs of the dials on the different apparatus.

Analysing air captured from the stratosphere.

On Earth we are protected from most radioactive particles by the atmosphere and the magnetic field.

It has been clearly demonstrated that birds are able to sense the direction of the Earth’s magnetic field and that they can use this information as part of a compass sense. It may be possible humans retain some residual magnetoreceptor in our eyes that once allowed us to navigate using the Earth’s magnetic field. Current research suggests that some people do indeed perceive magnetic fields, albeit unconsciously.

Work in progress on navigation by magnetic receptors. Working on a soft ground etching of my iris with aquatint. Not sure yet if I will use the plate or the print in the final work which will have iron filings activated across the surface.

First components have arrived from America for my attempt to build my own cosmic ray detector to create an interactive artwork. The plastic block converts the energy of the charged particle passing through to a photon which can be read by a silicon photo-multiplier and the information fed to an Arduino processor. Daunting and exciting.

Visit to Sutton Hoo where the ever increasing accuracy of radio carbon dating has provided astonishing clues to the past history of this intriguing site. Archaeologists can determine the age of objects in decades as opposed to centuries.

Sutton Hoo is the site of two early medieval cemeteries dating from the 6th to 7th centuries near Woodbridge, in Suffolk, England. In 1939 landowner Mrs Edith Pretty asked local archaeologist Basil Brown to investigate the largest of several Anglo-Saxon burial mounds on her property. Inside, he made one of the most spectacular archaeological discoveries of all time.

Past, present and future finds. Ancient trees. Burials of Kings. Amazing sword of beaten twisted wrought iron and steel. Basil Brown’s star charts.

The agency and aura of objects was investigated with the intent to generate new relations between objects and their associations with the world around them in the beautiful group show Can We Ever Know The Meaning Of These Objects curated by Sarah Sparkes and Kevin Quigley at Gallery 46.

Eileen Agar Angel of Anarchy at Whitechapel Gallery exposing the subconscious entwined with the material of nature. Enjoyed the decomposition of space into lines like foliations and contour lines. Which angel would you choose? Anarchy or Mercy?

I joined a zoom presentation from Sophie Williamson on her current project undead matter which dips into the deep time entanglement of geological ancestry. Leaving a mark in the past as a way of communicating with the future and creating a lineage for ourselves. Eras mingle with each other as ancient footprints resurface, ice melts, secreted narratives emerge. The permafrost holds vast amounts of carbon. Whole forests.

Zircon crystal contains radioactive uranium with a half-life of 4.5 billion years, which makes it useful for dating extremely old materials much much older than those containing Carbon-14. These crystals may hold clues to the origin of life. The carbon necessary for life may have arrived here in space dust from outer space via asteroids or comets.

Michael Armitage – Paradise Edict at the Royal Academy. Digital images do not do justice to the glow and vibrancy of these paintings. Can feel the heat pulsating with unsettling shape-shifting undercurrents.

180 The Strand with Ryoji Ikeda’s digital showcase was an intense assault on the senses using light and sound as medium to create immersive experiences. Brightness is the number of photons per second hitting your eye. Pushing the limits of what our senses can tolerate.

Took a trip to the Lake District to visit Brantwood, John Ruskin’s beautiful home to see Carol Wyss The Mind Has Mountains and Crown of Creation installations. Having seen the work that went into the printing of the large etchings at Thames-side Print Studio it was wonderful to be able to see the work finally installed and step inside the mysterious depths of the human skull; a space echoed by the surrounding mountains. The light installation is suspended in the dark chill of the Ice House vault, viewed from the top of rugged steps carved into the rock. Here the fragility of the human skeleton fades and glows accompanied by an evocative soundscape made by Natasha Lohan capturing the echoing chamber and the water that courses through everything.

New work pentacoronae installed at Grizedale Project Space for In Search of Darkness exhibition curated by art collective Lumen Studios.

1809 Pentacoronae

“Sky glow” is the yellow umbra leaching into the night sky from light polluting urban areas; obscuring our view of the constellations, shrinking our universe and severing our relationship to the stars.
Our ancestors mapped the stars and the shapes and patterns they drew across the darkness became familiar anchors for navigation; describing mythological characters; aligning celestial cycles with the fortunes of everyday life and revealing harbingers of portentous events. This rich history is being lost to a population bathed in the radiant intensity of artificial illumination.

1809 Pentacoronae 2
Light doesn’t always make things more visible. There are other ways to discover the mysteries of the universe and look beyond what our immediate senses tell us is there. Dark Matter is a significant component of the universe, yet we cannot see it. It doesn’t reflect or emit light and so scientists are finding other ways to detect it. In digital visualisations of Dark Matter, organic patterns emerge that could be the veins under our skin or the spreading branches of trees.

1809 Pentacoronae 1
As ever more powerful telescopes and data gathering equipment open new areas of the universe to our view, generating imagery we could never see with our naked eyes, we are drawn to experience space via mediated technologies. Dark sky areas such as Grizedale Forest are precious locations where we can still stargaze, wonder and map our own stories across the sky.

1809 Cloud Chamber demo

A cloud chamber gives us a glimpse into the invisible world of particles produced in the radioactive decay of naturally occurring elements and those generated when cosmic rays strike the top of the Earth’s atmosphere. It is a sealed environment containing a supersaturated vapour of pure alcohol sitting over dry ice. Charged particles passing through the chamber cause the vapour to condense resulting in tiny cascading trails. These particles pass though us continuously without our awareness. Witnessing this usually unseen activity can lead us to look beyond what our immediate senses tell us is there and consider the possibility of other intangible phenomena.

Holly Graham Sweet Swollen at Jerwood Project Space. The seductive title is evocative of succulent ripened fruit but also the tenderness of a bruise. This poignant work draws on the history of sugar as a luxury brought to our shores in the 18th century with the taint of colonial violence and the demeaning of those forced to produce treats for European palates. A series of sugar lift etchings depict hands in isolation, the gestures originating from the stylised ‘blackamoor’ figurines that ornament receptacles of the bitter sweet cargo.

Charmaine Watkiss showing beautiful ephemeral work at the MA Drawing Final Show at Wimbledon College of Art. A collision of then and now, displacement of body and soul, reaching back for symbols of meaning.

Highlights at this years New Scientist Live were talks from Jon Butterworth – Journeys into Particle Physics, Roberto Trotta – What Has Einstein ever done for you? and Dean Burnett – What makes your brain happy?

I came away thinking about what influences my perception of time and the chemicals that subtlety alter how I experience the world.

If you travel close to the speed of light, distances contract in your direction of motion, while time will dilate more and more the faster you move.  A muon lives: about 2.2 microseconds on average. The speed limit of the Universe = the speed of light. Something moving at the speed of light that only lives 2.2 microseconds, should make it only 0.66 kilometers before decaying. A muon has similar properties to an electron. However, it is 200 times heavier. Muons travel at approximately 98% of the speed of light. The closer you move to the speed of light, the slower your clock appears to run. Cosmic ray muons have such high energies that a journey which takes about 300 microseconds from our point-of-view only takes about 1 microsecond for the muon. Time dilation allows these particles to live.

I am beginning research for the High Altitude Balloon project. I need so much help! The good people of the HAB community are thankfully giving me lots of advice. One big concern is that the Allenheads Contemporary Arts potential launch site is high up and in the centre of a very narrow bit of the UK.  Wind makes for a difficult launch and could just take it straight out to sea.

1809 windy HAB.jpg

One of my first jobs is to check with the Civil Aviation Authority that the launch site is safe from their perspective.

18090 CAA.JPG

I want to film particularly at the altitude where peak cosmic ray activity takes place – this is where the secondary particles that we see in the cloud chamber are smashed into existence.  As the particle activity will be invisible I want to film the aesthetics of the curve of the earth and blue haze of the atmosphere bleeding into the blackness of space. I think my target height will be 30km.

1809 cosmic trails.jpg

Cosmic rays are mostly protons and atomic nuclei created in stars and super novae explosions or other unknown events.  Sometimes a rare one will arrive with unimaginably high energy. The first “Oh-My-God particle” was recorded in October 1991 and had an energy 40 million times greater than the Large Hadron Collider can generate with 100 quintillion the photon energy of visible light, it was travelling at 99.999 999 999 999 999 999 999 51% the speed of light. One of these could be passing through you right now.
