Evidence for the big crunch
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. … See more 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. The See more A theory called "Big Bounce" proposes that the universe could collapse to the state where it began and then initiate another Big Bang, … See more Paul Davies considered a scenario in which the Big Crunch happens about 100 billion years from the present. In his model, the contracting universe would evolve roughly like the expanding phase in reverse.

Web1 day ago · Introduction. The Big Bang theory is the prevailing cosmological model for the universe. It states that the universe was once in an extremely hot and dense state that expanded rapidly. This rapid expansion caused the universe to cool and resulted in its present size and composition. The Big Bang theory is supported by a variety of evidence ... WebThe Big Crunch, Big Crunch, or Big Implosion theory proposes that the universe will eventually contract to re-form a great singularity in space-time. ... Although the universe is expanding at the moment, and there is much evidence to support this, the Big Crunch suggests that gravity will at some point be powerful enough to stop this expansion ...
