Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe’s gravitational wave background—the constant flow of waves that churn through the cosmos, ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Parts of his theory line up with real-world concerns over the likes of the Hadron Collider at Cern, suggesting that the creation of the new energy will force a rift in the fabric of space-time. His ...

It sounds like science fiction: a spacecraft, no heavier than a paperclip, propelled by a laser beam and hurtling through space at the speed of light toward a black hole, on a mission to probe the ...

It will be a view unlike any other — completely invisible, exceptionally quiet and utterly transformative. Deep in the first moments of the Big Bang, the entire cosmos shook and rumbled. Those quakes ...
