MARS: Adrift on the Hourglass Sea (2011)

Envisioning an expedition and civilization on Mars, the work focuses on societies in crisis and on the brink of major change, and although the work appears alien, the DYI and recycled nature of some of the materials in each photo makes everything appear familiar.

Rare Book: Wunderzeichenbuch, or ‘Book Of Miracles’, 1552

“In AD 1119, fiery arrows or spears appeared in the sky, everywhere in the whole sky. And stars fell from the sky and when water was poured over them, they made a sound or screamed.”

It doesn’t exactly have the militaristic crispness of a Patrick Moore, but in these words (or, at least, their High German equivalent) we can see the modern science of astronomy emerging from under a shroud of superstition and folklore. The words are taken from an unparalleled Wunderzeichenbuch – or “book of miracles” – recently sold by James Faber, of Bond Street fine-art dealers Day & Faber. The miracles in question, all 167 of them, are hand-painted in gouache and watercolor and arranged in chronological order, from Old Testament scenes (the Flood, the parting of the Red Sea) to the Last Judgement. The main body of the work, however, is given over to events from recorded history, apocalyptic scenes such as a rain of meat in Liguria or a plague of vipers in Hungary; it’s a Renaissance equivalent of cranks’ newsletter The Fortean Times, albeit with a distinct focus on the astronomical. Some 60 or so of the folios depict cosmic events, particularly comets, painted with inventive élan and highlighted with gold leaf.

Space Settlements / spreading life throughout the solar system

"I know that humans will colonize the solar system and one day go beyond." Mike Griffin, former NASA Administrator.

A billion years ago there was no life on land. In a phenomenal development, by 400 million years ago land life was well established. We are at the very beginning of a similar, perhaps even more important, development. Today Earth teems with life, but as far as we know, in the vast reaches of space there are only a handful of astronauts, a few plants and animals, and some bacteria and fungi; mostly on the International Space Station. We can change that. In the 1970’s Princeton physicist Gerard O’Neill, with the help of NASA Ames Research Center and Stanford University, discovered that we can build gigantic spaceships, big enough to live in. These free-space settlements could be wonderful places to live; about the size of a California beach town and endowed with weightless recreation, fantastic views, freedom, elbow-room in spades, and great wealth. In time, we may see millions of free-space settlements in our solar system alone. Building them, particularly the first one, is a monumental challenge.

A trip to Orion and Horsehead Nebula
The Horsehead Nebula, a part of the optical nebula IC434 and also known as Barnard 33, was first recorded in 1888 on a photographic plate taken at the Harvard College Observatory. Its coincidental appearance as the profile of a horse’s head and neck has led to its becoming one of the most familiar astronomical objects. It is, in fact, an extremely dense cloud projecting in front of the ionized gas that provides the pink glow so nicely revealed in this GIF.

The Holographic Universe Principle: What is & What Should Never be
as read on fromquarkstoquasars.com
Given all of the recent coverage on the radical idea that the universe is one massive hologram, we thought we would take a few minutes to delve into what that really means for us. Basically, the holographic universe principle suggests that we’re living in a simulated reality (different from the hypothesis that states we live in a computer simulation), where our physical world is nothing more than a detailed illusion. This illusion is actually projected by our brains, as energy fields are being decoded into the seemingly 3 dimensional universe we see around us. In a more speculative sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure, which is “painted” on the cosmological horizon, such that the three dimensions (four, if you include time) we observe are only an effective description at macroscopic scales and at low energies.

“Our brain mathematically constructs objective reality by interpreting frequencies that are ultimately from another dimension, a deeper order of existence that is beyond both space and time” says David Bohm, who is the primary voice behind the holographic universe principle. (He certainly is not the only scientist that consider it a viable hypothesis. Brian Greene, author of “The Elegant Universe” is one of them.)  Bohm was dissatisfied with standard cosmological theories that couldn’t explain diverse phenomena predicted by quantum mechanics. He was also very interested in  understanding how they relate to the neuropathology of the brain.

Einstein called entanglement “spooky action at a distance.”–       Image Source

So, in 1982, an experiment was conducted by a research team led by physicist Alain Aspect at the Institute of Theoretical And Applied Optics, in Paris. It was discovered that under certain conditions, subatomic particles (such as electrons) are able to instantaneously communicate with each other regardless of the distance separating them. It doesn’t matter whether they are 10 feet or 10 billion miles apart. Somehow the particles always seem to know what the other is doing. We now call this “quantum entanglement, and it’s one of the more baffling aspects of particle physics, mostly because the underlying theme appears to contradict Einstein’s theory of special relativity, which says NOTHING can travel faster than the speed of light. (including information)

Overall, the experiment demonstrated that the web of subatomic particles that compose  our physical universe – the so-called “fabric of reality itself” – possess what appears to be an undeniable “holographic” property. If true, the holographic principle would comprehensively include reality as we know it, but also previously unexplained phenomena, such as the paranormal, along with “out-of-body experiences,” telepathy, lucid dreaming and near-death experiences (among other things).
Before we get ahead of ourselves with why this theory is unlikely, lets talk a bit about the properties that would give this hypothesis some credence:

“The Laser Interferometer Space Antenna” searches for gravitational waves – Image Source

First, we know that dense celestial objects, like black holes, neutron stars and pulsars, have immense gravitational fields that should give way togravitational waves — one of the most sought after aspects of quantum physics. One particular German team that is searching for evidence of gravitational waves, the GEO600 team, were met with some kind ofunexplainable eerie noise, which disrupted the GEO 600 detector from doing its job properly. One researcher from the Fermilab in Batavia, Craig Hogan, has proposed an interesting solution to the mystery (formally known as “quantum noise“): He thinks that there must be a fundamental limit of space/time, where the smoothness of the space/time continuum begins to break down into “grains,” similar to pixels that comprise images on a computer screen.
In his mind, this finding (the noise)  suggests that the entirety of the universe is merely the 3D projection of information found on a 2 dimensional information structure (you can liken it to that of a CD). Said structure is located at the very “edge” of the universe and the projection occurs when light bounces off from it, causing the light to scatter throughout the universe. His conclusion is somewhat vindicated by some of the observations we’ve made about the manner in which black holes behave, along with the Hawking radiation that continues to leak from them over time.
Enter stage left, the “Black Hole Firewall Paradox,” which has been a highly debated subject amongst physicists far more intelligent than I am. So, I’ll let one of them explain this:


Image Source:

“Information encoded in an event horizon “is born from other well known interpretations of the cosmos, in particularly the black hole paradox. As something falls into a black hole, passing the event horizon, the quantum information held in the event horizon can be encoded to reveal information about the interior. Therefore, the information inside the black hole’s event horizon is not destroyed (note: for details on this, see the Thorne-Hawking-Preskill bet). If the information about the interior of a black hole is encoded in its event horizon, scientists have come forward to point out that perhaps the information inside our Universe is encoded in the Universe’s horizon.”
What does that mean? Well, If you’ve been an avid reader of this page, you may remember an article I wrote about what would hypothetically happen to you if you were to survive the descent into the event horizon of a super-duper massive black-hole. In this, I basically said that along with the time dilation associated with the curvature of space/time, you would (hypothetically) be able to observe the entire history of the black hole’s existence simultaneously. The holographic principle is the same on a larger scale. All of the information should be encoded in the event horizon of our universe in Planck Length bits of space/time, and everything within is a projection of the 2D inner shell.
Now, as for why this theory is unlikely:


This is the gamma ray in question. Image: ESA – Source


The European Space Agency’s “Integral gamma-ray observatory” was initially opened in 2010. It’s capable of measuring gamma-radiation and its counterpart, gamma-ray bursts, which is one of the most powerful and destructive forces of nature. Depending on their highly unpredictable behavior, it’s possible for the observatory to be able to study these bursts to determine if space/time does indeed become “grainy” or pixilated at a quantum level. One particular burst traversed space for nearly 300 million light-years, before reaching our planet. Yet,  no blurriness in the fabric of space/time was observed, at least not down to 10^48 meters — ten trillion times smaller than the fundamental unit of length in quantum physics, Planck length. Of which, physicists are unsure if it’s even possible for a unit of length that’s smaller than Planck length to exist. So, this is one pretty monumental strike against the holographic universe principle.
There is still one other explanation that can’t be ruled out though, on this train of thought; perhaps gamma-ray photons behave differently than expected via the holographic principle? We still have a lot more to understand about the fabric of space/time, the universe and rectifying quantum mechanics with other well established scientific theories. This one.. this one makes my head hurt.

La Planète Sauvage (Fantastic Planet) 1973

a suggestion for you that are staying home, this Sunday night…

Fantastic Planet (French: La Planète sauvage) is a 1973 cutout stop motion science fiction allegorical film directed by René Laloux, production designed by Roland Topor, written by both of them and animated at Jiří Trnka Studio

watch the Film

The polar view has become possible because Cassini has changed the angle of its orbit
In the image, red indicates clouds at lower altitudes, with green representing higher altitude

Saturn hurricane snapped by Cassini craft

An enormous hurricane raging at Saturn’s north pole has an eye 2,000km (1,250mi) across - big enough to cover the UK 12 times over.

The striking images of the storm were snapped from a height of 420.000km (260,000mi) by the Cassini spacecraft, which arrived at Saturn in 2004.

They were captured in red and infrared wavelengths and have been false-coloured to show detail.

CONTINUUM

trailer

by Planetary Collective

Remember our previous video post on our sub-blog on space OVERVIEW?

OVERVIEW is actually the prelude to Planetary Collective’s forthcoming project CONTINUUM, a feature documentary film about our deep interdependence with each other, the planet and the universe. They tell us that this perspective is the key to understanding the grave crises we currently face as a civilisation and as a planet. If you haven’t seen the trailer yet, here it is (video above)…

Planetary Collective a team of three self-taught filmmakers who took a chance, quit their jobs, and have been living in the back of trucks and on people’s floors for nearly two years in order to make this film a reality. And with your support in this final phase they will be able to launch the film in February, 2014. If you haven’t seen the project, please check out the Kickstarter page and make a pledge. There are only 12 days left in the campaign, so please do so before March 24th.

 Explanation:  The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. The aboveimage is a digital combination of a ground-based image from the 0.9-meter telescope at Kitt Peak National Observatory and a space-based image from the Hubble Space Telescope highlighting sharp features normally too red to be seen. Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of the Hunting Dogs (Canes Venatici. M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies. Astronomers speculate that M51’s spiral structure is primarily due to its gravitational interaction with a smaller galaxy just off the top of the image.
