Scientists measure the smallest gravitational field yet
The experiment showed Newton's law of gravity holds true even between tiny masses measuring just 90 milligrams.
NASA releases beautiful new animation of a black hole
It's a space-time-bender!
Physicists say sound waves might actually carry mass
And it might be 'negative' mass to boot!
New gravity earthquake detection method might buy more time for early warnings
This means a couple of extra seconds which could make all the difference in a life or death situation.
New NASA data reveals many of Jupiter’s hidden secrets
It's a trove of valuable data, but we're still just scratching the surface.
The Sun is slowly losing mass as it ages, weakening its grip on the planets
Are you breaking up with us, Sun?!
The Power of Gravity and Its Capabilities
I don't think you understand the gravity of this subject.
Physicists report new, solid observation of gravitational waves
It's pretty much official now: we have gravitational waves.
Gravity map reveals Martian crust might be lighter than we thought
Mars may be more porous than we thought.
A flat-earther brought a spirit level on a plane to prove the Earth is flat. Yeah…
It's seriously unacceptable.

Still hot inside the Moon? Earth gravity creating a hot layer
Scientists have indirectly demonstrated the existence of a hot layer surrounding the Moon's core, through seismic and deformation studies. This ...
Our Universe may be just a Hologram, complex simulations show
In a black hole, Albert Einstein's theory of gravity clashes with quantum physics; for decades, scientists have tried to find ...
