Scientists have defined the speed of light in a vacuum to be exactly 299,792,458 meters per second, which is 983,559,096 feet per second. So a ray of light in a vacuum could travel a foot in 983,559,096 millionths of a second, which is pretty fast.
Traveling 39 light years would take 39 years at the speed of light.
Traveling 40 light years would take 40 years at the speed of light.
Light travels a distance of one light year in one year.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
Traveling to another galaxy at the speed of light would take an incredibly long time. The closest galaxy to us, the Andromeda galaxy, is about 2.5 million light-years away. This means it would take 2.5 million years to reach Andromeda at the speed of light.
It takes 1.3 to 1.4 nanoseconds for light to travel 1 foot.
One nanosecond.
3 months
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
That depends on the speed at which one is traveling.
It takes about 8 minutes.
It takes light exactly one hour to travel in 1 hour.
8 minutes
It depends where you live
(Assuming the you are planning on going the speed of light)3,153,600,000,000,000,000,000or3.1 sextillionor3.1 thousand trillionI assume however that you thought this number would be lower. As fast as light is, it will still take around 100, 000 years to cross the galaxy. In one nanosecond light will travel around 1 foot.
Light take approximately 8 minute 20 seconds to travel from the sun to the earth.
Just divide the speed of light by the distance.
