It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – ...

Weather permitting, SpaceX Falcon 9 may be visible in the sky beyond Cape Canaveral, Florida, after liftoff. Early morning and nighttime launches can offer unique photo opportunities as the rocket ...

A groundbreaking study published in Science Advances has confirmed one of Albert Einstein’s predictions from over a century ago: spacetime vortices, also known as frame-dragging, have been directly ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy lifting was more challenging than I initially thought." When you purchase ...

Scientists observing a dramatic cosmic outburst have confirmed a prediction first explored in Albert Einstein’s work on relativity more than a century ago. A global team detected the first clear signs ...

You probably noticed those glowing tears in spacetime as you explored the lands of The Outer Worlds 2. Those angry tears are actually rift anomalies, and they're accessible once you have the Rift ...

For years, TRISH has supported research projects and studies that aim to solve the challenges of human exploration in space. To understand how to solve those challenges, we first must know the risks ...
