Our universe expands by merging with ‘baby universes’, study suggests

Our universe is getting bigger and bigger really fast — something all the theories about space agree on, but none of them can totally explain. Now, there’s a new idea in town: Maybe our universe is expanding because it keeps bumping into and soaking up “baby” universes.
When scientists look at the afterglow of the Big Bang, known as the cosmic microwave background, they see that our universe is swelling up quicker and quicker. To make sense of this, physicists use something called the Standard Cosmological Model, which says there’s this weird stuff called dark energy pushing the universe to expand.
