Light is everywhere,it illuminates our world, enables vision, and travels across galaxies. But what is light, really? Is it a wave or a particle? The answer is both,and neither, depending on how ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there.

Wave-particle duality is a cornerstone of quantum mechanics, which is our modern theory of how subatomic particles behave.

The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there are still important aspects that can be covered in a short article.

In the traditional formulation of quantum mechanics, when a particle is measured -- meaning it is found to be in one particular location -- the wave function is said to collapse.

But until we figure out a way to test quantum gravity using gravitational waves, we won't know whether the "particle" part of wave-particle duality holds for gravitons.
