And that is absolutely 100% accurate, with no measurement errors. But Jack, I hear you say, what are you talking about? The reason we know that that's exactly the speed of light, is that we defined it ...

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 ...

The first successful measurement of the speed of light took place in 1676. Danish astronomer Ole Rømer was trying to measure the orbit of Io, Jupiter's third largest moon, by watching how long it took ...

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 ...

(Phys.org) —Physicist James Franson of the University of Maryland, Baltimore County has captured the attention of the physics community by posting an article to the peer-reviewed New Journal of ...

Einstein’s famous equation states that energy (E) equals mass (m) times the speed of light squared (c 2); the speed of light (c) is a universal physical constant exactly equal to 299,792,458 meters ...

Simple, child-like curiosity taught us at a young age, that if we push an object, it will move. If we push harder, it will move faster and remain in motion longer. Clearly though, there are both ...

The Parker Solar Probe, currently the fastest human-made object, travels at 0.05% the speed of light (approximately 330,000 mph). Reaching 1% the speed of light requires an immense amount of energy ...

Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. So, what does this mean? In short, it means that, the moment ...

This post is part of Science of Sci-Fi(opens in a new tab), Mashable's ongoing series dissecting the science (or lack of science) in our favorite sci-fi movies, TV shows, and books. With current ...
