Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Pulsars could be helping scientists distinguish between gravitational waves caused by supermassive black hole collisions and ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...

Theoretical computer scientists are always probing the relationship of space (memory) and time. For 50 years, experts knew that a calculation of X steps required X/log X memory slots, but a new study ...

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 ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

Star Trek's iconic warp drive, once pure science fiction, is now inspiring real-world astrophysicists. Scientists are developing theoretical models t ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

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 ...

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, ...
