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.

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.

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.

The behemoths exert a pressure on their surroundings, new research has found.

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.

Certain weird gravity conditions would make it possible to travel through a wormhole and back.

What would a universe flooded with primordial black holes look like?

With its frigid temperatures, remoteness from the sun and general dustiness, changing Mars to be more Earth-like is more challenging than it seems (and it already seems pretty tough).

Theories that attempt to resolve the so-called black hole information paradox predict that black holes are much more complicated than general relativity suggests.

The supermassive black hole in the center of our galaxy may not be a black hole at all, but rather a fluffy ball of dark matter called darkinos.

For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal — that is, if it looks the same no matter how large the scale.

Physicists have long been unable to describe what happened just after the Big Bang when a teensy blip ballooned into the universe, a process called inflation. We may know why.

Believe it or not, physicists are attempting to understand the universe when it was only a handful of seconds old.

The hypothetical Planet Nine may not be a planet but rather a small black hole that might be detectable from the theoretical radiation emitted from its edge, so-called Hawking radiation.
