The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

Gravity is the unseen force that shapes the universe, yet we rarely give it much thought. First explained by Sir Isaac Newton, it is the pull that draws objects toward one another based on their mass ...

What might happen if gravity disappeared for five seconds. Actor James Ransone, who starred in 'The Wire,' dies from an apparent suicide at 46 Winter weather warning as 40 inches of snow to hit—travel ...

(via PBS Space Time) There are four fundamental forces - the strong and weak nuclear forces, electromagnetism, and gravity. Except maybe gravity is no more fundamental than the force of a stretched ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Bad things happen to a human body in zero gravity. Just look at what happens to astronauts who spend time in orbit: Bones disintegrate. Muscles weaken. So does immunity. “When you go up into space,” ...
