"The Big Bang was an autotelic cosmic seed, and the universe is an organism for cultivating Consciousness: All history is the history of the evolutionary transubstantiation of matter to Spirit via biological-life processes of Blood and Reason."In a very general term, the Universe is essentially everything in existence. No one knows for sure how it will end or how big it is but ongoing research and various studies have certainly given us some clues.
Over the next several billion years after the Cooling Epoch, the Universe began to take shape in a period known as the Structure Epoch. It was during this time that visible matter was distributed among structures of varying sizes including stars, planets, and galaxies. The Lambda-Cold Dark Matter model is the standard model of Big Bang cosmology, and in it, dark matter particles move much slower compared to the speed of light. Under this model cold dark matter accounts for around 23% of the Universe, while baryonic matter accounts for less than 5%. The remainder is said to be made up of dark energy. The next phase of evolution in the Universe came in the form of an acceleration known as the Cosmic Acceleration Epoch. Exactly when this period began is still under debate, but it was roughly around 5 billion years ago (around 8.8 billion years after the Big Bang).
Ok, so now let’s think about the fate of the Universe and how it may someday end. Modern theories tend to include the existence of dark energy and have led scientists to believe that eventually all of our Universe will go beyond our event horizon and become invisible, leading to catastrophic outcomes. The field of astronomy has been studied since the time of the Ancient Babylonians. Greek and Indian scholars then added to the field which included work from Thales and Anaximander who believed everything was made of a primordial form of matter. The idea that the Universe consisted of four elements (fire, earth, water, and air) was first proposed by a westerner back in the 5th century BCE by Empedocles. It was also around this time that the idea the Universe composed of atoms came about and that all matter was in fact made up of energy.
A Cold Spot In Space — “Evidence” of a Multiverse?
It sounds bonkers but the latest piece of evidence that could favour a multiverse comes from the UK’s Royal Astronomical Society. They recently published a study on the so-called ‘cold spot’. This is a particularly cool patch of space seen in the radiation produced by the formation of the Universe more than 13 billion years ago.
The cold spot was first glimpsed by NASA’s WMAP satellite in 2004, and then confirmed by ESA’s Planck mission in 2013. It is supremely puzzling. Most astronomers and cosmologists believe that it is highly unlikely to have been produced by the birth of the universe as it is mathematically difficult for the leading theory — which is called inflation — to explain.
This latest study claims to rule out a last-ditch prosaic explanation: that the cold spot is an optical illusion produced by a lack of intervening galaxies.
One of the study’s authors, Professor Tom Shanks of Durham University, told the RAS, “We can’t entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard [theory of the Big Bang]. But if that isn’t the answer, then there are more exotic explanations. Perhaps the most exciting of these is that the Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed, analysis … proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse.” [Emphasis added.]
If not explained by a ΛCDM ISW effect the Cold Spot could have more exotic primordial origins. If it is a non-Gaussian feature, then explanations would then include either the presence in the early universe of topological defects such as textures (Cruz et al. 2007) or inhomogeneous re-heating associated with non-standard inflation (Bueno Sa ́nchez 2014). Another explanation could be that the Cold Spot is the remnant of a collision between our Universe and another ‘bubble’ universe during an early inflationary phase (Chang et al. 2009, Larjo & Levi 2010). It must be borne in mind that even without a supervoid the Cold Spot may still be caused by an unlikely statistical fluctuation in the standard (Gaussian) ΛCDM cosmology.
You’d be able to move forward or backward in time, just as you can in space, say while walking down a corridor. You’d also be able to see the similarities and differences between the world we inhabit and other possible ones. In the sixth dimension, you’d move along not a line but a plane of possibilities and be able to compare and contrast them. In the fifth and sixth dimensions, no matter where in space you inhabit, you’d witness every possible permutation of what can occur past, present, and future.
In the seventh, eighth, and ninth dimensions, the possibility of other universes open up, ones where the very physical forces of nature change, places where gravity operates differently and the speed of light is different. Just as in the fifth and sixth dimensions, where all possible permutations in the universe are evident before you, in the seventh dimension every possibility for these other universes, operating under these new laws, becomes clear.
In the eighth dimension, we reach the plane of all possible histories and futures for each universe, branching out into infinity. In the ninth dimension, all universal laws of physics and the conditions in each universe become apparent. Finally, in the tenth dimension, we reach the point where everything becomes possible and imaginable.
For string theory to work, six dimensions are required for it to operate in a manner that’s consistent with nature. Since these other dimensions are on such a small scale, we’ll need another way to find evidence of their existence. One way would be to peer into the past using powerful telescopes which can hunt for light from billions of years ago, when the universe was first born.
String theory has an answer for what came before the Big Bang. The universe was made up of nine perfectly symmetrical dimensions, the tenth being time. Meanwhile, the four fundamental forces were united at extremely high temperatures. The structure was under high pressure. It soon became unstable and broke in two. This became two different forms of time and led to the three dimensional universe we recognize today. Meanwhile, those other six dimensions shrunk way down to the subatomic level.
As for gravity, string theory contends that the basic units of the universe are strings— infinitesimally small, vibrating filaments of energy. They’re so tiny, they’d be measured on the Planck scale—the smallest scale known to physics. Each string vibrates at a specific frequency and represents a certain force. Gravity and all the other forces are therefore a result of the vibrations of specific strings.
One problem is that this theory is hard to test, outside of advanced mathematical equations. Some experiments have been done using supercomputers, which can run simulations and make predictions. That isn’t exactly enough to prove that it’s true, but it’s helpful and lends support. Besides astronomical observations, physicists are hopeful that experiments with the Large Hadron Collider at CERN, on the Franco-Swiss border, may offer evidence of extra dimensions, lending string theory greater credence.
They have made use of the Sloan Foundation Telescope for two years and surveyed the universe under the project Sloan Digital Sky Survey’s Extended Baryon Oscillation Spectroscopic Survey (eBOSS), enabling them measure three-dimensional positions of more than 147,000 quasars.
Quasars are the bright and distant points of light, visible all the way across the universe. When matter and energy fall into a quasar’s black hole, they heat up to incredible temperatures and glow, which could be detected by the 2.5 metre Sloan Foundation Telescope on Earth.
Ashley Ross of the Ohio State University said, “That makes them the ideal objects to use to make the biggest map yet.”
After successfully creating a three-dimensional map of where the quasars are, scientists used another method that involved studying “baryon acoustic oscillations”, which configured sound waves that travelled through the early universe, when it was much hotter and denser than the present-day universe.
The explanation for this sound waves detection is that when the universe was 380,000 years old, certain conditions changed suddenly and the sound waves became “frozen” and left imprinted in the three-dimensional structure of the universe we see today.
The results of the new study follow the predictions of Einstein’s General Theory of Relativity, besides including other components whose effects can be measured.
