Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Back in February of 2016, LIGO made an announcement that changed our ...

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 ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

Antimatter isn't just made of antiparticles, it's also made of waves. Now we know that this holds true even at the level of a single antimatter particle. Physicists have known for a long time that ...

According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real? When you purchase through ...

Complementarity A new twist on the double-slit experiment. (Courtesy: Shutterstock/Andrey VP) One of the most counterintuitive concepts in physics – the idea that quantum objects are complementary, ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
