Solving the enduring mystery of the speed of gravity will have broad implications for fundamental physics and our understanding of the cosmos.

We may finally understand the speed of gravity

We May Finally Understand the Speed of Gravity

We had no way to directly measure the speed of gravity. Now, that's changed.

Some of Star Trek’s most “far out” technologies could one day be a reality.

General Relativity says spacetime can warp.

Is Warp Drive Physically Possible?

“With the CHIME telescope, we will measure the expansion history of the universe.”

The CHIME telescope will give us a whole new view of the structure of the universe

The telescope is expected to provide answers about our universe, distant stars, and gravitational waves.

CHIME could also help us confirm the final aspect of Albert Einstein’s theory of general relativity.

Time travel isn't possible...or is it?

Time travel of a sort is possible, but not in the sci-fi/fantasy way you're probably thinking of. The theory of relativity comes into play here.

Time Travel Isn’t Possible…or Is It?

The speed at which you move through space determines the speed at which you move through time.

The future of General Relativity is bright.

Albert Einstein's theory of General Relativity has led to our discovery of black holes, gravitational lensing, and gravitational waves. However, for about 30 years, scientists wrote the theory off as a small correction to Newtonian gravity.

Einstein’s Theory of General Relativity was Largely Ignored for Three Decades

Scientists at the time thought the theory was too complex compared to Newton's.

For decades now, scientists have been investigating the possibility that our Universe is, or once was, a giant hologram. It sounds far-fetched, but if true, it would actually solve some pretty hefty questions in physics

Here’s What Scientists Mean When They Say the Universe Could Be a Giant Hologram

It sounds far-fetched, but if true, it would actually solve some pretty hefty questions in physics.

Predicted by Einstein as part of his theory of general relativity, this could help measure the mass of distant stars using gravitational deflection.

Scientists Finally Witnessed a Phenomenon That Einstein Thought “Impossible”

"Einstein would be proud."

A new study from the University of British Columbia postulates that the Universe is expanding due to fluctuations in space and time.

New Explanation for Dark Energy? Tiny Fluctuations of Time and Space.

One of the universe's greatest mysteries could be solved by combining two conflicting theories.

Henry from Minute Physics takes a stab at explaining the physics of time with simple graphics in his sketch on Youtube.

Of course, that 3 minutes is relative.

Theoretical physicists demonstrated a fundamental flaw in our ability to measure time, citing quantum mechanics and general relativity.
