The international team has created a new computer algorithm to hunt for such irregularities in our universe, which they say would be disk-shaped—think of the temporary, circular flattening that happens when one beach ball bumps into another.

Because the multiverse would likely have expanded so fast that its universes would have been pulled far apart shortly after their creation, collisions would likely have occurred only during our universe's infancy.
Luckily, modern telescopes are able to study a sort of faint baby picture of the universe: the cosmic microwave background. The CMB is radiation emitted by the hot plasma that dominated the universe up until about 380,000 years after the
