A universe that expands forever will yield a "big chill" or a "big freeze." This shocking discovery earned three astrophysicists If dark energy continues to exert the same force on the universe in the future, then space will continue to expand, the distance between galaxies stretching wider and wider and at a faster and faster pace. Big Crunch Another, equally dire possibility is that the strength of dark energy diminishes over time. The universe becomes a relatively lonely place.

Here are two of them:Tired eyes?

Clearly, further advances in fundamental physics are required before it will be possible to know the ultimate fate of the universe with any level of certainty. Even the formation of the recently discovered massive black hole the size of 12 billion suns only 875 million years after the Big Bang could be more easily explained in the context of a Big Crunch contracting universe. The Big Crunch is one of the scenarios predicted by scientists in which the Universe may end. "The universe is kind of humbling when you look at it and start to appreciate its scale," Allen said. "At some point galaxies themselves could be ripped apart," said Martin Bojowald, a physicist at Pennsylvania State University. Many possible futures have been predicted by different scientific hyp "Another, equally dire possibility is that the strength of dark energy diminishes over time. Based on these three things, cosmologists have come up with three possible scenarios that explain how the end of universe could come to be. The Experimental evidence in the late 1990s and early 2000s (namely the observation of distant However, Roger Penrose advances a general relativity based theory (called the McSween, Stephen A. Just like many others, it is based on Einstein’s Theory of General Relativity. Let your ears help you learn for a change.

"On the brighter side, any eventuality will take billions or even trillions of years to occur, long after our great-great-great-great-great-great-grandchildren should be past caring. V. The Big Crunch scenario hypothesized that the density of matter throughout the universe is sufficiently high that gravitational attraction will overcome the expansion which began with the Big Bang. Alternatively, the Universe could 'shrink', decrease or decay, effectively reversing the Big Bang and destroying the Universe in a Big Crunch. Death, whether it is a living things and Non – Living things. The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big Bang.The vast majority of evidence indicates that this theory is not correct. [If dark energy became weak enough, gravity might ultimately win the tug of war and pull the universe back in on itself. Here are some episodes from Astronomy Cast that just might suit your taste:In this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe. Not only are scientists unsure how the universe will end, they aren't even sure it will end at all. Just for added information, an increasing dark energy strength would have supported the possibility of a Big Rip, another universe ending that predicted everything (including atoms) to be ripped apart.Even with an unchanging dark energy strength, an ever expanding universe is still the most likely scenario. In a Big Crunch, dark energy would weaken and reverse sign, causing the Universe to reach a maximum size, turn around, and contract. NY 10036. In the contracting phase of a Big Crunch universe, there is no accelerating expansion for gravity to overcome. A third theory is described as the Big Freeze. Now, acc
