In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.
However, only a portion of the universe would be destroyed by the Big Slurp while most of the universe would still be unaffected because galaxies located further than 4,200 megaparsecs (13 billion light-years) away from each other are moving away from each other faster than the speed of light while the Big Slurp itself cannot expand faster than ...
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. [21] [22] False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable. [23] [24] [25]
The estimated time until the end of the universe in a Big Rip, assuming a model of dark energy with w = −1.5. [123] [124] If the density of dark energy is less than −1, then the universe's expansion will continue to accelerate and the observable universe will grow ever sparser.
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 absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
The Big Three are paying a big price to end the UAW strike — but that won’t necessarily jack up car prices. Analysis by Elisabeth Buchwald, CNN. October 31, 2023 at 3:06 AM.
The end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. Observations of galaxy cluster speeds by the Chandra X-ray Observatory suggest that the true value of w is ~-0.991, meaning the Big Rip will not occur. [218] 10¹⁰⁰: Various
Pick up your favorite drink right now and pour it on the ground: OS X is dead. Yep, so at last night’s WWDC, Apple all but confirmed the end of OS X and with it the 10.XX numbering system we ...
