Do you age faster in space than on Earth? Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted...
How much faster is time in space? Clocks on the International Space Station (ISS), for example, run marginally more slowly than reference clocks back on Earth. This explains why astronauts on the ISS age more slowly, being 0.007 seconds behind for...
How Fast Is the Sun going around the galaxy? Yes, the Sun – in fact, our whole solar system – orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even...
How fast is the Milky Way moving? And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)! We are moving roughly in the direction on the...
What is the rotation speed of earth in kilometers per hour? Earth rotates once every 23h 56m (23.933h), so at the equator where Earth’s circumference is 2ΠR = 2×3. 14×6378 km = 40,000 km it has to travel at a speed...
Why don’t we feel the earth rotating? Since the Earth rotates at a near-constant speed (that is, it doesn’t speed up or slow down in any way noticeable to us), we simply spin with it and don’t feel a thing. Well,...
How much does time dilate near a black hole? At the point r=rs (this is the event horizon of the black hole), the length of the et-basis vector actually shrinks to zero, which physically corresponds to time dilation going to infinity....
Is gravitational time dilation proven? Yes, time goes faster the farther away you are from the earth’s surface compared to the time on the surface of the earth. This effect is known as “gravitational time dilation”. It is predicted by Einstein’s...

How is 1 hour 7 years in Interstellar? According to the movie, every hour on the water planet equals about 7 years on Earth. There are 3600 seconds in an hour, and (86400 x 365.25 x 7) or roughly 221,000,000 seconds...
