Two physicists from the University of Queensland in Australia recently laid out a model for studying hypothetical time travel. Their work expands on what’s called the Alcubierre spacetime, first ...

Faster-than-light (FTL) travel is a concept that has long captivated both the scientific community and science fiction enthusiasts. In a cosmos where light speed is viewed as the ultimate velocity ...

In late 2020, physicist Harold “Sonny” White, PhD, research director of the nonprofit Limitless Space Institute, noticed something peculiar—and familiar—in a circular pattern of data plots generated ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

Scientists have successfully tested a material design for light sails using photonic crystals that could achieve 20% the speed of light ...

Here’s what you’ll learn when you read this story: 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 ...

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, ...
