Can We Use Gravitational Waves For Space Travel? The Short Answer: A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). How do gravitational waves effect space time? Each new generation of waves is weaker than the last, but the effect
Can Light Be Deflected By Magnetic Fields? Can light be deflected by magnetic fields? Although a magnetic field doesn’t affect the photons of light directly, a magnet can distort the medium through which light passes and thereby “bend” the light rays. Light travels through space-time along a geodesic – the shortest possible path between two
Did Albert Einstein Discover Black Holes? Did Albert Einstein discover black holes? Thanks to astronomers and computer scientists working with the Event Horizon Telescope (EHT), a network of eight linked telescopes, humanity was finally able to visualize these “infinitesimal dots.” Although Einstein wasn’t alive to see evidence of black holes—the result of real singularities about
Do Distant Stars Have Gravity? Do distant stars have gravity? By looking at slight variations in the brightness of distant stars, scientists say they can determine their surface gravity, a technique that provides important clues to life-hosting properties of the planets that orbit them. Do galaxies have gravity? A galaxy is a huge collection of
