Every generation grows up with starships that jump across galaxies in a heartbeat, but the real universe is far less forgiving than the screen. The same physics that lets GPS satellites work and ...

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 ...

Imagine you’re in a car driving across the country watching the landscape. A tree in the distance gets closer to your car, passes right by you, then moves off again in the distance behind you. Of ...

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 ...

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...

Science fiction authors and readers dream of travelling at the speed of light, but Einstein tells us we can’t. You might think that’s an arbitrary rule, but [FloatHeadPhysics] shows a different way to ...

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

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, ...
