“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Key Takeaways on What Space-Time Is Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity.

In a first, scientists have observed a binary-star pair so massive they drag the space-time continuum around them.

Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the theory of general relativity, revealing how mass and energy bend the ...

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time.
