An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.

You're about to take a dip into the inky blackness of a giant black hole and see what's on the other side of that enigmatic event horizon. What will you find inside? Read on, brave explorer.

A brand-new particle has possibly emerged and is altering the future destiny of our entire cosmos, a physicist says.

Physicists have figured out what's lurking inside of white dwarfs, revealing the stellar corpses are creamy and filled with exotic quantum liquids.

The 1995 discovery showed that the sun isn't the only star to host a family of planets — something we had long figured but never demonstrated — and also that the universe is really, really weird.

Physicists are scouring the universe for evidence that one of the fundamental constants of nature, Newton's gravity, is not constant at all.

Obviously, some chain of unfortunate events led to the ejection of 'Oumuamua from its home system. But what could possibly cause such a catastrophe?

Physicists have proposed that a trio of particles called Higgs bosons could be responsible for the mysterious vanishing act of antimatter in the universe.

Interstellar flight is a real pain in the neck.

The two giant blobs remain mysterious, nearly a decade after their discovery.

There are some odd little particles out there that are bound by the strong nuclear force, but physicists can barely get a glimpse of them before they flit out of existence.

Wherever they are, they sure are good at hiding.

All you need are a couple of black holes and some cosmic strings. No biggie.

A giant linear collider the size of Manhattan could finally help us find new physics, scientists argue.

Several giant experiments are hunting for neutrinos, the tiniest, most-elusive particles in the universe.

Tiny ripples called magnons could lure even a fleeting, lightweight dark matter particle out of hiding.

Why avoid the cosmic void?

...and break the laws of physics.

Here's how the biggest thing in the universe could reveal secrets of the smallest things.

I'm a particle that really isn't; I vanish before I can even be detected, yet can be seen. I break your understanding of physics but don't overhaul your knowledge. Who am I?
