Since childhood, we’ve been told gravity is the force that holds everything together — but what if that idea is incomplete, ...

Dissident scientists advocating a controversial theory of the universe are having a field day in the wake of NASA's Deep Impact comet collision earlier this month. Scientists promoting the Electric ...

The Big Bang theory has provided the most widely accepted basis of our understanding of the universe since it was first proposed by Georges Lemaitre in 1927. In short, it posits that all the matter in ...

For centuries, gravity has been the cornerstone of physics—but what if it’s not the universe’s true force? The Electric Universe theory claims that invisible cosmic currents shape stars, planets, and ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

A team of researchers from the University of British Columbia, Canada, has proposed a radical new theory about the expansion of the universe. Scientists do not know exactly why the universe is ...

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much. On the morning of ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of How to Die in Space. He contributed this article to ...

Astronomers have proposed a new theory to suggest why our universe is expanding at an accelerating rate. That our universe is expanding is in wide agreement, though how exactly that process happens is ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with its own laws of physics. But ...
