Jul 3, 2015 · For a Big Rip to occur, dark energy must win in its battle with gravity to such a point where it can rip apart individual atoms. He began by looking at the stickiness of the universe -- or how ...

Whatever event happens beyond this era is highly speculative. It is possible that a Big Rip event may occur far off into the future. [52] [53] This singularity would take place at a finite scale factor. If the current vacuum state is a false vacuum, the vacuum may decay into an even lower-energy state. [54]
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.
Oct 10, 2016 · The Big Rip. The first theory claims the Universe will end with a Big Rip, as the pull of the Universe's expansion gets stronger than the gravity it contains. This would tear apart galaxies ...

The reason we can investigate the past evolution of the universe is that, in some regards, astronomy is analogous to archaeology. Explicitly: the further we peer away from our home planet, the further back in time we see in to the universe. And when we look far back in time, we observe that galaxies are closer together than they are at present. Alt...
Late last century, one of the most pressing issues in modern cosmology was to measure the deceleration rate of the universe. Given the amount of mass observed in the cosmos it was thought that it might be enough to cause an eventual contraction of the expansion. Remarkably, two independent teams of scientists found the exact opposite. The universe ...
Before turning to the very distant future, I will mention another relevant survey: GAMA. Using that survey, we found that the universe is slowly “dying”. Put another way: the peak era of star formation is well behind us, and the universe is already fading. The more “immediate” future can be predicted with some certainty. Five billion years from now...
All of the above seem very bleak to say the least. So I will end this article on a highly speculative, probably wrong, completely untestable, but more positive, note. According to the strange rules of quantum mechanics, random things can pop up from a vacuum. And it is not just a mathematical quirk: the existence of particles suddenly coming into e...
Sep 4, 2015 · The data from the WiggleZ survey and other experiments do not rule out the Big Rip, but push it in to the exceptionally far future (if at all). Somewhat more pressing is the heat death of the ...
Feb 25, 2016 · The team found that the earliest a big rip can occur is at 1.2 times the current age of the universe, which works out to be around 2.8 billion years from now. “We’re safe,” says Sáez-Gómez.
