Let's explore the possibility of traveling to universes beyond our own — if they so exist, that is. While parallel universes ... could you go into the past without changing it?

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead ... the observed acceleration without the need for dark energy.

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

This was a relief to Edwin Hubble’s contemporary, Albert Einstein, who deduced the universe could not remain stationary without imploding under gravity’s pull. The rate of cosmic expansion is now ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

The Hubble tension grows: new data shows the Universe’s expansion defies current physics models, suggesting our understanding of cosmology may need a major overhaul. Credit: SciTechDaily.com New ...
