From the most distant stars in the sky to the screen in front of your face, light is everywhere. But the exact nature of ...

Everyday experience tells us that light reflected from a perfectly flat mirror will give us the correct image without any deformation. Interestingly, this is not the case when the light field itself ...

Astronomers have found more evidence that there is a massive ripple traveling through the Milky Way. They have found evidence that stars at the edge of the galactic disk are moving like people doing ...

Sam Baron receives funding from the Australian Research Council. Hi Ishan! Thanks for your great question. Light can be described both as a wave and as a particle. There are two experiments in ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

In 1676, by studying the motion of Jupiter's moon Io, Danish astronomer Ole Rømer calculated that light travels at a finite speed. Two years later, building on data gathered by Rømer, Dutch ...

We explore if there is a true connection between light and gravity. We know that gravity exerts its pull on light, and we have an explanation for why. Actually, we have multiple explanations that all ...

Science is often viewed as utilitarian. We explore the natural world so that we can plunder its secrets for our own benefit. Indeed, this is often precisely the sort of science that funding agencies ...

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. When you purchase through links on our site, we may earn an ...
