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

New theories suggest the speed of light isn’t just a number, but evidence that reality itself is curved. What looks like a ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

One of Einstein's most famous fundamental laws is that nothing in the Universe can travel faster than the speed of light in a vacuum. If you're a massless particle, you must travel at that speed, and ...

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 ...

When your Peeps have gone stale, it's time to donate their marshmallow bodies to science — specifically, for measuring the speed of light. From time to time, NPR's science desk creates videos that ...

(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 ...

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 ...

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 speed of light, and the latitude of the ancient Egyptian Great Pyramid of Giza, are the same figure, but what does this actually mean?

Look inside a science fiction computer, and you’ll probably see tubes and cubes that emit light. Of course, it’s for effect, ...
