Water is very heavy – and it can move. Until now, changes to water on land have actually offset much of the rising sea level from ice melt. How? Gravity
Recent research shows the main alternative theory to dark matter, Milgromian dynamics, is failing.
Textbooks often show Earth’s orbit around the Sun as an almost egg-shaped ellipse. The real story is very different.
Observations during historical solar eclipses confirmed Einstein’s theory of gravity, and led to the predictions of black holes.
People have been flying airplanes for well over a century. Engineers know how to balance all the forces at play, but still aren’t exactly sure how some of the physics of flight actually works.
A centuries-old experiment shows the differences between classical and modern physics. Physicists use thought experiments like this to think about how objects move both on Earth and in the stars.
If we lived in a cosmic area with below average density, it would explain recent contradictory measurements of the universe’s expansion.
When you’re an astronaut landing on the Moon, you can’t rely on the same gravitational cues we have on Earth. But regimented training with sensory devices could one day prevent spatial disorientation.
The gravitational field can affect space and time: the stronger gravity is, the slower time moves. This prediction of General Relativity can be used to reveal hidden forces acting on dark matter.
It seems there isn’t a sci-fi part if the universe in which everything is made of antimatter.
Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
Space can damage everything from your cardiovascular and nervous systems to your mental health – long voyages can feel isolating for many.
Black holes are known for pulling in all kinds of stuff – including light. Here’s how that actually works.
The Euclid mission is preparing to launch on July 1.
To understand this question, we need to travel back in time.
How does flowing water make electricity? An engineer explains hydroelectric generation.
The theory of gravity may need to be altered.
Strangely behaving matter could one day explain some of the mysteries of space.
A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.
