How many times would light go around Earth in one year? That’s about 200,000,000 (two hundred million). How many times can light travel around the Earth? Light can travel at a speed of 300,000 km (186,000 miles) a second. That means...
How long does light take to travel from Sun to Earth? The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but...
What is 1% the speed of light? While 1% of anything doesn’t sound like much, with light, that’s still really fast – close to 7 million miles per hour! At 1% the speed of light, it would take a little over...
How fast does lightning travel around the world? While the flashes we see as a result of a lightning strike travel at the speed of light (670,000,000 mph) an actual lightning strike travels at a comparatively gentle 270,000 mph. This means...
How long would it take to travel around the world at the speed of light? The idea of travelling at the speed of light is an attractive one for sci-fi writers. The speed of light is an incredible 299,792,458 meters per...
Can you travel at speed of sound? The ratio of the speed of an object to the speed of sound (in the same medium) is called the object’s Mach number. Objects moving at speeds greater than the speed of sound (Mach1)...
Why can’t we travel at the speed of light NASA? The theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that’s immensely difficult to...

How long is 1 year in space? A year in space is dependent on your location. We count a year as the time it takes for the Earth to revolve around the sun once. Jupiter for instance, would have it’s own...
What happens after astronauts come back to Earth? The human body is designed to work in Earth’s gravity, which means that when astronauts return to Earth, their bodies have to readjust to the planet’s gravitational force. Astronauts may experience a reduced...
