The new model to support that Big Rip theory was developed by Marcelo Disconzi, assistant professor of mathematics at Vanderbilt University in Tennessee in collaboration with physics professors Thomas Kephart and Robert Scherrer.Jul 3, 2015
When was the Big Rip theory created?
2003 First published in 2003, the 'Big Rip' is a cosmological hypothesis that predicts that all universal matter is being progressively torn apart as the universe expands. From atoms and subatomic particles to stars, planets and galaxies, the theory encompasses them all!
What caused the Big Rip?
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.
Why is the Big Rip not possible?
Because it's impossible to ever measure anything with complete, uncertainty-free precision, the best we may ever be able to do is say that if the Big Rip does occur, it will be so far in the future that all structure in the cosmos will have decayed already by the time it happens.
Is the Big Rip possible?
The key value is the equation of state parameter w, the ratio between the dark energy pressure and its energy density. 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.
What is pushing the universe apart?
The energy from the Big Bang drove the universe's early expansion. Since then, gravity and dark energy have engaged in a cosmic tug of war. Gravity pulls galaxies closer together; dark energy pushes them apart. Whether the universe is expanding or contracting depends on which force dominates, gravity or dark energy.
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.
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.
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.
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.
