Collisions between black holes can launch newly melded cosmic sinkholes at speeds up to nearly one-tenth the speed of light, researchers report August 18 in Physical Review Letters. Moving that fast — ...

One of the deepest mysteries in quantum physics is the wave-particle duality: every quantum object has properties of both a wave and a particle. Nowhere is this effect more beautifully demonstrated ...

In 1905, Albert Einstein provided an explanation of the photoelectric effect – that various metals emit electrons when light is shined on them – by suggesting that a beam of light is not simply a wave ...

One of the most controversial parts of modern physics is what it tells us about philosophy. Both quantum mechanics and special relativity have much to say on the limits of what can be casually related ...
