The circumference of the Earth is ~24902 miles or 40,076,000 meters.
This speed of light is 299,792,458 m/s.
So it takes 0.134 seconds to go around the earth once.

How long does it take long currents to complete their circuit of the globe?
An electrical signal in a copper wire moves roughly at 2/3 the speed of light in a vacuum, so, about 200,000 km/second. Since the Earth has a circumference of about 40,000 km, that means such a signal can go all around the Earth in 1/5 of a second.
How long does it take light to travel 100 meters?
If the light is in a vacuum then it would take around 0.00000033 seconds.
What is the current average GPS speed?
GPS signals are just radio waves, so they travel at or very near the speed of light, or 186,000 miles every second. The GPS satellites are in orbit at 11,000 miles above Earth, so they take very near to no time to travel from the satellite to the GPS receiver on Earth.
If a body were accelerating at a rate making its mass equal to its normal mass on earth how long would it need to travel before reaching light speed?
It would take infinitely long in both time and space, and require and infinite amount of energy to accelerate any object with mass to the speed of light. In other words, it is impossible to reach the speed of light. Einstein's equations show that as an object approaches the speed of light, it's kinetic energy is converted to mass making it heavier and heavier, require more force and energy to accelerate it. As a result at 99.999999% the speed of light the object would be come so massive that it would require more energy than the universe contains to push it fast enough to be going the speed of light.
Does light accelerate?
No. As long as it stays in the same material, its speed is constant.
How long would it take to travel at the speed of light from Earth to Aldebaran?
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
How long is it from earth to Uranus?
it takes about 2 hours at te speed of light.
What is the speed of light and how long does it take light to pass from the Sun to Earth?
Speed=3x10^8 m/s Time=8.3168708 minutes
How long would it take to get from earth to Uranus traveling at the speed of light?
3 days
How long would it take to get to the moon if you were traveling from the Earth at the speed of light?
About 1.5 seconds
How does the speed of light change as light change as light moves from a distant star toward earth in the vacuum of space?
As long as it remains in the vacuum in the vacuum, the speed of the light doesn't change at all.
How long can you walk from the time it takes the speed of light to travel form the sun to earth?
A few kilometers. It takes light about 8 minutes to reach Earth.
How long it takes to travel around the earth?
That depends on the speed. The circumference of the Earth is 40,000 km. Decide on a speed, then divide this distance by the speed. If the speed is in km/hour, the time will be in hours.
How long does it take to go to the moon by the speed of light?
At its average distance from the earth, the moon is 1.28 light seconds away.
For the moon to travel at the speed of light how long would it take to orbit the earth?
1 second
How long does light take to travel from the Earth to the Moon if the distance between them is 384000 km?
The speed of light is 300,000 km/second. If you divide the distance by this speed of light, you get the time in seconds: 1.28.
How long would it take light to traver around the world?
Light can travel once around the earth in .00013358 seconds.
