Due to how light travels, we can only see the most eye-popping details of space—like nebulas, supernovas, and black holes—with specialized telescopes. Electromagnetic Spectrum: the visible range ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

NORFOLK, Va. — A light year is exactly what it sounds like: the distance light travels in one year. If you need to get somewhere quick, you'd want to jump on this train because light travels through ...

What you see in the night sky is not always reality. There are many illusions up there. Whenever you gaze upon the starry sky you do not see the stars in real-time. You’re actually staring into the ...

GRAND RAPIDS, Mich. (WOOD) — I love this question from our most recent kid viewer, Sam. He wants to know how light can possibly travel millions and millions of miles through space all the way to the ...

The glow from faster-than-light particles gives us a unique way to explore the universe. Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past ...

Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the ...

A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

Faster than light travel may produce gravitational waves that we could see here on Earth. Warp drives may or may not be possible, but if they are then could a distant alien civilization’s warp fields ...
