A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

Ranging from the unimaginably small to the unimaginably big, the scale of the universe is mind-boggling. Watch to try to wrap your head around it. Produced by Alex Kuzoian. Follow BI Video ...

Theoretical physicists James Hartle and Stephen Hawking, for example, proposed that rather than having a strict beginning as we would understand it, the universe evolved out of a "no-boundary" state ...

"Really, Euclid is not only a dark universe detective, it's also a time machine. We will look back 10 billion years in cosmic ...

Temporarily, albeit on the cosmic scale of millions or perhaps billions of years. "If that is indeed the case, quantum mechanics would allow the universe to eventually tunnel to the lowest energy ...

During this phase, the scale factor of the universe, which tells us about its size, follows a cosine-like behavior. This behavior ensures that the universe emerges with a finite size at the moment ...

Starting at an everyday scale, we travel by powers of 100 down into the shadowy world of strings. That is, we begin 10 meters away from an apple, then zoom 100 times closer to 10 centimeters away ...
