End of the universe.
The universe and everything in it could end in less than 3.7 billion years from now, claims a new study.
The universe, began in a Big Bang about 13.7 billion years ago, has been expanding at an ever accelerating rate ever since and according to standard cosmology models it is most likely to expand forever. But, a team of physicists led by Raphael Bousso from the University of California, Berkeley, claimed that their calculations showed the universe would end most probably in the next 3.7 billion years, the Discovery News reported.
According to the team, there`s a “measure problem” in the cosmological theory of eternal inflation — the quantum cosmological model where inflationary bubbles can appear out of nothing.
Some of these bubbles, each being a universe, expand and go on forever while others collapse and disappear again. They pop in and out of existence like bubbles in boiling water, said the scientists.
In an eternally inflating universe, they said, every event that is possible will eventually occur — not just once, but an infinite number of times. This makes predicting when each event will occur impossible, such as the probability that a universe like ours exists. “If infinitely many observers throughout the universe win the lottery, on what grounds can one still claim that winning the lottery is unlikely?” they wrote in blog arXiv.org. pti
