Uncertainty is inherent to our Universe.
From time-traveling billiard balls to information-destroying black holes, the world's got plenty of puzzles that are hard to wrap your head around.
It could one day fuel nuclear fusion reactors.
The Big Bang is commonly misunderstood, warping our understanding about the Universe's size and shape.
Einstein’s theory of general relativity passes another test, with implications for dark matter and dark energy
The theory is accurate within at least one part in a quadrillion.
UAP are no laughing matter anymore.
Recent research suggests that Earth’s magnetic field bounced back just as complex life was starting to emerge on our planet.
An average undergraduate student in physics is better than the AI.
You would think that with all our technology, like the James Webb Space Telescope, we would know how big the Universe is. But we don't.
An astrophysicist explains these shortcuts through space-time.
The war in Ukraine is unlikely to trigger a catastrophic nuclear meltdown. Physics and smart engineering are the reasons why.

The surface of asteroid Bennu is more like a plastic ball pit than the Moon.
"The surface is no longer a record of every impact the moon has ever had, because at some point, impacts were erasing previous impacts."
Quantum communication offers a surer path to sending an interstellar message, as well as receiving one. But can we do it?
The costs of such an endeavor would be extremely high, while the potential payoffs would be uncertain.
