Quantum Leap met its small-screen end decades ago. But what was the real reason Sam Beckett never leaped again after the ...

Time travel has long been a subject of fascination in science fiction, but recent scientific endeavors suggest that it might not be as far-fetched as once thought. Researchers in laboratories around ...

Philosophical-sounding edge cases help scientists refine their models and explore how and where their theories may fail.

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

This week, researchers published LIGO findings that hint at the existence of second-generation black holes. Astronomers captured a spectacular new image of the Milky Way across a wide range of radio ...

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles can be in two places at once. Actions on one particle can instantly affect ...

In the physical world, time marches in one direction, but things aren’t so straight forward in the quantum realm. Researchers have discovered that it’s possible to speed up, slow down, or reverse the ...

It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true.

Let's explore the possibility of traveling to universes beyond our own — if they so exist, that is. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of “controlled closed timelike curves.” Though far out, ...
