The speed of light in a vacuum, clocking in at a showy 299,792,458 meters per second (98,3571,056 feet per second), plays a pretty darn important role in the laws of physics as we understand them – so ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. In science fiction, spaceships moving at or beyond lightspeed enable ...

In this video, we explore the concept of the speed of light and its implications. The discussion delves into the scientific principles behind light speed, why it’s a fascinating topic, and the ...

Imagine this: a tiny needle hurtling toward Earth at the speed of light. At first glance, it might sound like no big deal. After all, it’s just a needle. But in reality, a projectile moving this fast ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. The ...

Science fiction authors and readers dream of travelling at the speed of light, but Einstein tells us we can’t. You might think that’s an arbitrary rule, but [FloatHeadPhysics] shows a different way to ...

Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the ...

The iconic Pinwheel Galaxy, located 25 million light-years away. Hubble Image: NASA, ESA, K. Kuntz (JHU), F. Bresolin (University of Hawaii), J. Trauger (Jet ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks. When it comes to space travel, Albert Einstein's theory of relativity is a major ...
