An international team of researchers are suggesting that our understanding of the origins of our universe may need some updates.

As detailed in a new paper published this week in The Astrophysical Journal Letters, they say the universe may have begun with a “Big Bounce” rather than a Big Bang.

In other words, the cosmos may have been born following of the end of a previous cosmological phase — a bounce — and not the result of space-time inflating exponentially into existence.
