The lens of quantum physics offers a much simpler view of the Big Bang, research suggests.
A double sunset appears to be a true rarity in the cosmos, and general relativity explains why.
As internet conspiracy theories go, this one was exceptionally dumb.
At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?
A mathematical investigation of galactic data suggests elusive dark matter is confined to the rules of gravity.
If an extraterrestrial warp drive collapses, we might be able to sense the resulting gravitational waves from Earth.
The animation, which simulates the view of someone falling into a black hole, demonstrates how the bizarre objects warp light and space as you approach them.
A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics.
Gravastars within gravastars would be a mind-blowing answer to a conundrum established by Einstein.
Imagine LIGO, but flying through space. That’s LISA.
The super-dense object doesn't quite fit with what we know about black holes or neutron stars.
“Whether closed timelike curves exist in reality, we don’t know."
The result from CERN confirms expectations, but it's the first time gravity’s effect on the stuff has actually been tested.
A visualization of simulated data shows how ripples of spacetime might populate the Milky Way.
The spinning, dead star was emitting radiation in two modes, and a team of scientists believes it knows why.
The Event Horizon Explorer would build on the work of the Event Horizon Telescope, which famously visualized a black hole in 2019.
Cocoons of debris surrounding collapsing stars may generate gravitational waves detectable by LIGO.
The LIGO-Virgo-KAGRA Collaboration will restart with renewed sensitivity this week following a three-year hiatus.
The theorized object warps spacetime like a black hole but still releases light.
Pesky quantum behaviors are getting us closer to figuring out quantum gravity.
