Why does light carry energy even though it has no mass? This video explains the real physics behind photons, energy–momentum ...

Most of us can relate to being worried about inflation: we are all concerned about the cost of living and what our political leaders are doing to address it. Sometimes, I have to remind myself that we ...

Properties that remain unchanged when materials are stretched or bent, which are broadly referred to as topological ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Faster-than-light (FTL) travel is a staple of sci-fi, hand-waving away multi-millennia journeys between stars. Such a technology would of course be incredibly handy to us in the real world, and while ...

A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Scientists studying particle collisions have produced definitive evidence for two physics phenomena predicted more than 80 years ago: that matter/antimatter can be created directly by colliding ...

WHILE this book is written primarily to further our knowledge of the properties and uses of that form of energy called light, in the treatment of disease, yet it will be found of great interest to ...

With the rise of brain-interface technology and artificial intelligence that can imitate brain functions, understanding the nature of consciousness and how it interacts with reality is not just an age ...

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...
