BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and acceleration. Initially ridiculed, Einstein developed key concepts after observing a ...

Though most people have heard of Albert Einstein's theory of special relativity, what that theory really means and how it has impacted modern physics can be difficult for the non-physicist to grasp. A ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

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 ...
