The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

There is no denying the awesome predictive power of Albert Einstein's 1915 theory of gravity, general relativity — yet, the theory still has inconsistencies when it comes to calculating its effect on ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

For decades, black holes have stood as the most enigmatic objects in the universe, defying our understanding of space, time, ...

The discussion about the universe's fate has always been an interesting subject of debate, not only among scientists and ...

University of Chicago scientists have challenged the reigning theory about the puzzling nature of gamma-ray bursts, which signal the birth of black holes. A key element of their theory is the ...

A longstanding question in astronomy is what creates cosmic rays, the super-speedy space particles that can zip right through the Earth. The reigning explanation for cosmic rays has been that protons ...

Scientists announced today (March 17) that they have likely found the long-sought smoking gun for the theory of cosmic inflation, suggesting that the universe did indeed expand at many times the speed ...

According to big bang theory, for the first 10 - 43 seconds of the universe's life, all the forces of nature existed as one superforce. The universe was all energy, no matter. Physicists call this ...
