A joint UK-US team has put forward an alternative theory of cosmic evolution. It proposes that the Universe undergoes cycles of “Big Bangs” and “Big Crunches”, meaning our Universe is merely a “child of the previous one”.
It challenges the conventional view of the cosmos, which observations show to be 12-14 billion years old.
The new ideas, reported in the journal Science, may explain why the expansion of the Universe is accelerating, the researchers say. – bbc
