We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.

Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into ...

For the second time in as many months, images gathered by the Hubble Space Telescope (HST) are raising questions about the structures of time and gravity, and the fabric of space. Using two HST images ...

Q: I am a 78-year-old man who’s about an inch and a half shorter than he used to be at one time. Why am I shrinking? A: We’re all getting shorter with age. Blame gravity. There are 23 discs between ...
