Time is not absolute, with gravity and velocity affecting how fast it passes, making clocks at different heights or near ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object ...

Scientists have spent decades trying to understand how gravity operates at its most basic scale. However, no theory has come close to fully explaining it. Now, though, a new theory could finally give ...

Bottom line: For decades, physicists have been trying to solve one of the greatest mysteries in science: how gravity operates at the smallest scales governed by quantum mechanics. While we have ...
