An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational ...

In a landmark achievement, astronomers have noticed light bending in an unexpected manner, one that doesn’t align with the predictions made by Albert Einstein’s theory of general relativity. This ...

The study of black holes within the framework of general relativity continues to advance our understanding of gravitation under extreme conditions. Black holes, with their intricate interplay of mass, ...

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 ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

A pair of researchers have uncovered a potential bridge between general relativity and quantum mechanics — the two preeminent physics theories — and it could force physicists to rethink the very ...

In 1915, Germany introduced chlorine gas into the ongoing horror that was World War I. It was the war to end all wars, bringing devastation that would scar a generation. But one man’s mind continued ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS Space ...
