Alien life could exist in other universes, according to a group of scientists studying a mysterious force known as dark energy. Previous theories suggested our universe has the perfect amount of ...

Maybe we haven’t found alien life because it’s all evolving in other universes. A group of astronomers have just released a research paper suggesting that other universes could be far more ...

The concept of multiple universes goes back to the 6th century, when pre-Socratic Greek philosopher Anaximander suggested the ...

Whether other universes are membranes floating in space, or a quirk of quantum mechanics, this is how physicists think we’ll traverse the multiverse.

But traveling to the other universes wouldn't be easy, because they're far beyond our observable horizon and moving away faster than the speed of light. That would take a lot of frequent flyer miles.

It's easy to envisage other universes, governed by slightly different laws of physics, in which no intelligent life, nor indeed any kind of organized complex systems, could arise.

Researchers analyzed the amount of ordinary matter transformed into stars in simulated universes with varying dark energy densities. In a universe optimized for star formation, about 27% of ...

The universe is expanding faster and faster, but not all scientists agree that dark energy is the cause. Perhaps, instead, our universe keeps colliding with and absorbing smaller 'baby universes ...
