Einstein said everything falls at the same rate. Is that also true for a quantum top?
The Illusion Of Truth
What does truth have to do with science?
From Atoms To Everything
The pear-shaped nucleus of barium-144 could help solve one of the biggest mysteries in cosmology.
Are You A Black Hole?
You aren’t a black hole, and that means a particle moving at nearly the speed of light isn’t one either.
Hair Of The Dog
It turns out that black holes might have hair after all.
Looking For Higher Dimensions In Gravity
Some theories predict the existence of higher dimensions. With sensitive gravitational experiments we can test that idea.
The Theoretical Dream Of The EmDrive
Even if the EmDrive works as a new theoretical model claims, it still violates well tested laws of physics.
The Strange Case Of Decaying Neutrons
Two measurements of the radioactive half-life of free neutrons give results in disagreement with each other, and may point to new physics.
The Quantum Fluid Inside Neutron Stars
Ultracold liquid helium acts very similar to the hot interior of a neutron star.
