For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

What if the Big Bang didn't begin with a singularity? This point of infinite density, which so divides physicists, could be ...

Space and time looked settled, at least in broad outline. Einstein’s special relativity gave physics a durable framework for ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

A peer-reviewed paper published in The European Physical Journal C presents a modification to Einstein’s general relativity that eliminates the singularities associated with the Big Bang and Big ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

Albert Einstein's enduring quote, "If you can't explain it to a six year old, you don't understand it yourself," highlights that true intelligence lies in simplifying complex ideas. This philosophy ...
