How long does it take to travel 1 light year at the speed of light?

A light year is the distance that light travels in vacuum in one year, about 6 trillion miles or 10 trillion kilometers. One might therefore conclude that in order to travel one light year at one tenth the speed of light, this trip would take 10 years.

How long is 1 second at the speed of light?

299,792,458 metres
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).

Does time exist if you travel at the speed of light?

The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of “c” in reference to light.

Will we ever travel to other galaxies?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

Is it possible to travel at the speed of light?

Yes, I agree with David. If somehow, you were able to travel at the speed of light, it would seem that ‘your time’ would not have progressed in comparison to your reference time once you returned to ‘normal’ speeds. This can be modeled by the Lorentz time dilation equation:

What is the length of a second at the speed of light?

If we look mathematically, the picture is far more agitated and further difficult to comprehend. The observation is actually observer-dependent. So, if an observer at rest sees one travelling at the speed of light, its length is mathematically zero. The mass is mathematically infinite and a second takes infinitely long time.

Can we move relative to light?

In essence, there is only one “Light” and we are all in the exact same location relative to it. When we measure the speed of light we actually measure the speed of the propagation of light, the light never moves and has no speed. You also can’t move AT ALL relative to light.

What happens to mass when an object travels at the speed of light?

You see, if an object travels at the speed of light, its mass will increase exponentially! Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite.
