If you were to travel at the speed of light for a year, no time would pass for you, but approximately one year would pass on Earth.
The distance from the Earth to the Sun is approximately 93 million miles (about 150 million kilometers). At the speed of light, it would take light 500 seconds to travel this distance. This is because light travels at a speed of about 186,282 miles per second or 299,792 kilometers per second.
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.
According to the theory of relativity, as an object with mass approaches the speed of light, its mass would increase infinitely and require an infinite amount of energy to continue accelerating. Therefore, it is currently believed that it is impossible for an object with mass to reach the speed of light. If it were somehow possible, the consequences are not fully understood, but it is likely that the extreme forces and energy involved would have fatal effects on a human body.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 light-years away from Earth.
To determine the speed of an object, you would need to know the distance it has traveled and the time it took to cover that distance. Speed is calculated by dividing the distance traveled by the time taken to cover that distance.
If you traveled at the speed of light (a current impossibility), you would travel from Earth to the Sun in an average of 8 minutes. Or would you? I suspect that you would burn up well before the 8 minutes were up.
To an outside observer a person traveling at the speed of light would be frozen in time. To the person traveling at the speed of light, things would seem normal.
The distance from the Earth to the Sun is approximately 93 million miles (about 150 million kilometers). At the speed of light, it would take light 500 seconds to travel this distance. This is because light travels at a speed of about 186,282 miles per second or 299,792 kilometers per second.
The answer completely depends on what "close" means. There would be a big difference between 95% and 96%.
the only way i know how to time travel is that if you started at earth and went for a huge distance traveling at the speed of light (299,792,458 meters a second or 186,282 miles per second) then when you come back to earth you would have traveled in time. But the problem is we have nothing that can go near the speed of light and a lot of scientists say absolutely nothing can go faster then the speed of light.
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
Actually, the closest star to Earth is Sun which would be reached in a little more than 8 minutes.As for other stars, closest one is Proxima Centauri. You'd need to travel for 4 years and 2 months to reach it at the speed of light. You may or may not know that you have asked a delightful trick question. If I were traveling at the speed of light [impossible, of course] how long would it take me to get to earth's nearest star? From my point of view, the trip would be instantaneous. It would also be an instantaneous trip if I traveled to a destination 100 million light years away. Time completely stops at light speed. Observers on earth would conclude that the trip took me 8 minutes. We would all be right, within the scope of our individual frames of reference.
You would have traveled approximately 25 light years away from Earth and back. This is because traveling at near light speed as you experienced time dilation. The specific destination you would have reached depends on the speed and direction of your spaceship.
Assuming the comet is far away in the outer solar system, it would take light approximately 8 minutes to reach Earth from the Sun, and then more time to reach the comet depending on its distance. Traveling at the speed of light, it would take a few minutes to several hours or more to get from Earth to a comet, depending on its specific location in space.
If the speed of light traveled at the speed of sound, our entire perception of the universe would drastically change. The fast travel and instant communication enabled by the speed of light would no longer be possible, leading to a significant impact on technology, communication, and our understanding of the cosmos. The universe would appear much different to us due to the altered timeframes and distances involved.
No. The average speed would be the distance traveled divided by the elapsed time.
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.
