If −1 < w < 0, the expansion of the universe tends to accelerate, but the dark energy tends to dissipate over time, and the Big Rip does not happen. Phantom energy has w < −1, which means that its density increases as the universe expands.
Is the Big Rip possible?
One grim possible outcome is a Big Rip, which would ultimately unravel all matter down to the atomic level—though not for billions of years or longer.
How would the big rip happen?
Disconzi's hypothesis says that a Big Rip can occur when dark energy will become stronger than gravity, reaching a point when it can rip apart single atoms. The professor's model shows that as its expansion becomes infinite, the viscosity of the universe will be responsible for its destruction.
How long would Big Rip last?
22 billion years If the total amount of dark energy is increasing, the acceleration will also increase, eventually to the point where the very fabric of space-time tears itself apart and the cosmos pops out of existence. One prediction puts this hypothetical “big rip” scenario 22 billion years in the future.
What will happen after Big Rip?
If the Big Rip is real, then not only is the Universe expanding (which happens irrespective of dark energy), and not only will distant objects appear to accelerate away from us at increasingly faster and faster rates as time goes on (which happens because of dark energy), but objects which are bound together through …
What is the Black Hole Era?
The Black Hole Era is defined as "40 < n < 100". In this era, according to the book, organized matter will remain only in the form of black holes. Black holes themselves slowly "evaporate" away the matter contained in them, by the quantum mechanical process of Hawking radiation.
How long until the universe ends?
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. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.
What happens if the universe rips?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
How will universe end?
There are a few ways the universe might end, but exactly how depends on how the rate of cosmic expansion changes in the future. If gravity overpowers expansion, the cosmos will collapse in a Big Crunch. If the universe continues to expand indefinitely, as expected, we'll face a Big Freeze.
What is the Big Freeze theory?
Cosmologists have pondered the ultimate fate of the universe, and many have converged on a theory: the “heat death of the universe,” also known as the “Big Freeze.” The Big Freeze theory suggests that, one day, all the energy in the universe will become evenly distributed, preventing any further action from occurring.
