A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

This also means that there could be hidden curvatures of space-time or gravitational fields, which could explain a fundamental issue in physics: the hierarchy problem. There are several ongoing ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

Einstein's theory on the expansion of the universe might be wrong. At least, that's the running idea behind a new study published in Classical and Quantum Gravity earlier this month. The study was led ...

Given how unfathomably large the universe is, it is perhaps understandable that we haven’t yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we ...

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 ...

A fan theory suggests iconic Arnold Schwarzenegger vehicles "The Terminator" and "Predator" take place in the same universe.
