The likelihood of a Big Crunch in which the universe expands to the point that it then collapses inward upon itself is not very probable as mathematical calculations demonstrate that there simply isn’t enough mass in the entire universe to be able to revert into into an enormous compaction. The idea of the universe folding in upon itself can be visualized by imagining a person throwing a ball in the air. The Earth has enough mass to bring a thrown ball back down to the ground but if thrown faster than the speed of escape velocity which is 11.186 kilometers per second, a thrown ball would never come back down, in fact, it would travel an infinite distance over an infinite timespan before the Earth mathematically had enough time and mass to pull the ball back to its starting position. The universe is represented by the Earth in that it acts as a force upon other objects and the ball represents all matter throughout the universe in this thought experiment

# The Physics of the Pac-Man Universe

The game of Pac-Man allows players to exit the world on one side, and re-enter upon a completely different side without delay. Pac-Man’s universe appears to be a flat, two dimensional, rectangular shape, but in reality it must be cylindrical like a pipe, only with the 2 ends of the pipe touching, making Pac-Man’s universe actually in the shape of a donut

# Mathematical Evidence of the Observable Universe Actually Being Part of a Multiverse

There are 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 or 10^{80} or 100 quinquavigintillion subatomic particles in the universe, often referred to as the “Eddington number” which means that mathematically speaking, eventually after shuffling these particles over and over, the same result is bound to occur. This is precisely why the theory of the multiverse appears to be valid. These particles cannot be rearranged an infinite amount of times and therefore identical copies of the observable universe surely must show up in other parallel universes, as well as countless variations of the universe in which conditions are similar to the observable universe, but still different in some significant or insignificant manner. In a multiverse scenario, every single possible outcome is played out. After an estimated 10^{10^100} or 1 googolplex (1 googol being 10 with 100 zeros behind it and a googolplex being 10 with 1 googol zeros behind it) meters away from the observable universe in terms of linear measurable distance in space, another universe should theoretically be in existence already, a universe which is identical to the observable universe in every way imaginable. Because nearly every universe is uniquely different, the laws of physics could and should be vastly contrasting to what an observer within the observable universe experiences. It is estimated that there are between 10^{10^16} – 10^{10^10^7} or 100 septentrigintillion – 100 trecenquattuortrigintillion different universes. This estimate is predicated upon the fact that the amount of information which a single individual can absorb is 10,000,000,000,000,000 or 10^{16} or 10 quadrillion bits of data within their lifetime, which is equivalent to 10^{10^16} or 100 septentrigintillion configurations, and this means that the human brain is physically incapable of distinguishing more than 10^{10^16 }or 100 septentrigintillion universes

# Hugh Everett’s “Many World’s” Theory

Hugh Everett designed the Many World’s Theory which states that if in the first world a particle is found on the left side, in the second world that same particle is found on the right side, with both findings being equally valid. Everett’s main conclusion was that when a particle splits in 2 to act as a wave, the universe also splits into 2 pieces, only going through 1 of the 2 available slits, but doing so in separate universes. The Many World’s theory is now generally accepted as fact by most physicists, however Everett died before receiving the recognition he deserved for his work. Everett’s theory was treated with a frosty reception when it was first released, as most scientists considered such a theory to be science fiction and speculation rather than proper observed and analyzed fact

# Edwin Hubble’s Greatest Discovery

Edwin Hubble was the first person to notice variability within the luminosity of stars. From this, Hubble was able to work out the distance between the Earth and any star in the universe. This permitted Hubble to calculate how far the Andromeda Galaxy was which is the galaxy nearest to Earth. Albert Einstein did not believe the implications of his own equations and thus added lambda, expressed as “Λ”, to his equations. Lamda was designed to act as an antigravity force, an addition Einstein stated was “necessary only for the purposes of making a quasi static distribution of matter” which means to “maintain the status quo” or to “keep things as they always were”. Once lambda was removed from Einstein’s equations, each one fit perfectly with the observable model of the universe as they account for expansion. Einstein refused to believe the universe was constantly undergoing expansion until years after scientists had confirmed it to be true

# The Ancient Greek Philosopher Thales

The Ancient Greek philosopher Thales, considered the world’s first philosopher by Aristotle, used geometry to calculate the distance of ships from the shoreline, the height of the Great Pyramids of Egypt, was the first person to predict a solar eclipse, and posited a cause for earthquakes. Thales perceived that the earth floated upon water like a giant raft which of course was wrong, but his scientific inquiry into the reasons as to why things occur rather than attributing it to the god’s was the first glimmering scintillation of a revolutionary way of thinking. Thales inspired more great minds like Pythagoras who developed the concept that numbers and mathematics could explain the universe, and Hippocrates who developed an ethical code for practicing medicine

# The Big Bang Theory Nearly Proven

The reason the Big Bang Theory is nearly proven is because it is well understood that energy is equivalent to mass multiplied by the speed of light squared which was discovered by Albert Einstein through his most famous equation, E=mc^{2}. At very high temperatures, matter becomes energy and an almost infinite amount of energy can be crammed into an almost infinitely tiny space. This energy/matter however is not entirely stable and therefore it must eventually expand outwards. This principal of physics demonstrates that the entire universe could fit into something the size of a marble or less
