Reference Photons carry the electromagnetic force, and act as both particles and waves.
Toxic hydrogen cyanide gas, used in chemical weapons today, may have been involved in the early stages of life's evolution, a new study suggests.
Does the simulation hypothesis offer a compelling argument, or is it just interesting food for thought? Let's find out.
The Higgs boson particle could have kept our universe from collapsing within a larger multiverse, physicists say.
The Pacific Ocean Neutrino Experiment would turn a massive swath of the Pacific Ocean into nature's own neutrino detector.
Hiding beneath the outer layers of some planets, there may be something spectacular: a constant rain of diamonds.
The recently launched James Webb Telescope should help determine if dark matter is made up of primordial black holes.
A multiverse may be a natural prediction of the physical theories that define the beginning of the universe.
In a recent study, researchers determined that about 1% of all the "normal" (that is, not dark) matter in the universe is bound up inside black holes.
Wormholes may be stable after all, a new theory suggests, contradicting previous predictions that these hypothetical shortcuts through space-time would instantly collapse.
Wormholes connect two points in space and time and are a staple of science fiction. But are they possible in the real universe?
Cosmic rays are tiny subatomic particles racing through the universe at nearly the speed of light — and they're not so nice.
There are places in the universe where our laws of physics simply break down. These are called singularities.
James Clerk Maxwell is the scientist responsible for explaining the forces behind the radio in your car, the magnets on your fridge, the heat of a warm summer day and the charge on a battery.
Physicists sifting through old particle accelerator data have found evidence of a highly-elusive, never-before-seen process: a so-called triangle singularity.
A new theory suggests dark matter may have come from quantum bags that got squished together in the early universe.
Asteroids are packed with gold and other valuable resources. And the best way to harvest those metals may be to bring space rocks to Earth.
