Interstellar flight is a real pain in the neck.
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.
Physicists on the hunt for the invisible hand that shapes our universe and the galaxies within it have turned their gaze to the dark side.
A giant linear collider the size of Manhattan could finally help us find new physics, scientists argue.
Our lives here on Earth are small and insignificant and inconsequential — but only in a certain frame of reference, and that frame of reference doesn't necessarily apply to cosmic scales.
Moons of "hot Jupiter" alien worlds may detach from their parent planets and begin orbiting stars on their own.
Tiny ripples called magnons could lure even a fleeting, lightweight dark matter particle out of hiding.
Clusters of galaxies hold the prestigious title of "largest gravitationally bound structures in the universe," which is no small feat.
The universe really likes its information — but black holes pose a huge paradox physicists can't yet solve.
At the very largest scales — zooming out from solar systems, stellar clusters and even galaxies — a surprising pattern emerges in nature.
It's a perennial sci-fi favorite: other worlds, other universes, other possibilities, right beyond the bounds of the known cosmos or just a flick of a magic device away.
All four known forces of nature have their own unique place — and the strong nuclear force governs the very small.
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?
