An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be ...

Light and sound are very different. Sound is actually a mechanical disturbance through air or another medium. Sound always needs a medium to travel through, and the type of medium determines its speed ...

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 ...

The idea of traveling faster than the speed of light (FTL) has been a popular idea long before [Alcubierre] came up with the first plausible theoretical underpinnings for such a technology. Yet even ...

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal ...

Faster-than-light travel is impossible according to our current understanding of physics. Wormholes are theoretically possible but require unstable, exotic matter to stabilize. Generation ships are a ...

When it comes to space travel, Albert Einstein's theory of relativity is a major inconvenience. With the laws of physics (currently) prohibiting faster-than-light travel, velocities are limited to a ...

Lawbreakers? faster-than-light Polarization Currents, The Electromagnetic “Boom” and Pulsar Observational Data Pulsars are neutron stars that emit amazingly regular, short bursts of radio waves, so ...

Faster than light travel may produce gravitational waves that we could see here on Earth. Warp drives may or may not be possible, but if they are then could a distant alien civilization’s warp fields ...
