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 ...

It's the most fundamental law of special relativity, and the realization that led Einstein to some of the greatest physics breakthroughs of all time: the idea that nothing can travel faster than light ...

The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one ...

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 ...

(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 ...

In the summer of 1926, an experimental beam of light pierced the night sky between two precisely measured peaks in the San Gabriel Mountains, and science history was made. Virtually unseen by the ...

New Scientist is reporting that NASA engineer David Burns is making some bold claims about a conceptual new spaceship thruster he calls the “helical engine” — a concept the magazine admits “may ...

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 ...
