Here's what you'll learn when you read this story: Although people often say nothing travels faster than the speed of light, this cosmic speed limit only pertains to particles with information or mass ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

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 ...

Special relativity is one of the most strongly validated theories humanity has ever devised. It is central to everything from space travel and GPS to our electrical power grid. Central to relativity ...

A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By ...

Chapters 0:00 - All light is basically the same 1:44 - Our slow-mo world 2:38 - Doppler effect 4:38 - How colors distort near speed of light 8:09 - Relativistic aberration (searchlight effect) 8:58 - ...

Imagine you’re in a car driving across the country watching the landscape. A tree in the distance gets closer to your car, passes right by you, then moves off again in the distance behind you. Of ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

A reanalysis of cosmic gamma-ray measurements found no evidence of the tested departures from Lorentz invariance. The researchers tightened limits on specific photon-sector parameters by about a ...

During a meeting with the Mars Exploration Program Analysis Group, an internal NASA working crew dedicated to supporting missions to Mars included a pitch from Elon Musk's SpaceX to deploy Starlink ...

I'll be honest: I didn't know that an iPhone was able to do a lidar scan. (The iPhone 12 Pro, 13 Pro, and iPad Pro can all do it.) When I found out that my phone could, I became obsessed with scanning ...
