South Africa has one of the world's richest fossil records of hominins (humans and their fossil ancestors). But many ...

The curious minds at Aperture show how Einstein’s theory of relativity reshaped how we think about time, space, and gravity.

These general knowledge questions have been curated to cover various subjects to engage young minds in a fun and informative ...

For decades, he hid his time-travel obsession. Now, he is challenging the assumptions that underpin our universe.

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory suggested that gravity could bend light by curving the fabric of spacetime.

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

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 ...

For more than a century, Albert Einstein’s General Theory of Relativity has provided a surprisingly accurate framework for understanding the gravitational machinations of the universe. However ...

Einstein published the theory in 1905, and one of its foundational elements is that light speed (186,000 miles per second) is the universal speed limit. Nothing can travel faster than light.

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...
