What else can I help you with?
How much time would pass on Earth if I traveled at the speed of light for a year?
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.
Traveling at speed of light how much time will pass in 70 years on earth?
None. At the speed of light, time stops completely. It is impossible for anything with an invariant mass to move at the speed of light; only particles with no "rest mass" (such as photons) can do so.
How long does it take light incident perpendicular to the glass to pass through this 8.7 cm thick sandwich?
Light takes approximately 29 microseconds to pass through 8.7 cm of glass when incident perpendicular to the surface. This time is calculated based on the speed of light in glass, which is about 0.67 times the speed of light in a vacuum.
Relationship of the speed of light in a vacuum to the speed of light in a medium where it will pass through?
Refractive index is the ratio of speeds.
What are the effects of traveling at near the speed of light?
If you travel near the speed of light, then, from the point of view of somebody who is NOT travelling with you (say, someone who stays behind on Earth):Time will pass slower for you.Distances for you will be shorter (in the direction of travel).Your mass will increase.
Can you pass the speed of light?
In all but very exceptional circumstances, no.
If light waves change speed as they pass from one medium into another at an angle the light will be?
If light waves change speed as they pass from one medium into another at an angle, the light will be refracted, meaning it will bend as it enters the new medium. This bending is due to the change in speed of the light wave.
If a solid mass travels at the speed of light and it passes through the suns ray to earth would it be seen?
A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.
If two entities are traveling to each other with 60 percent of the light speed is one going back in time from the viewpoint of the other?
No, time will appear to pass slower, but that doesn't mean time will seem to go backwards.If EACH object travels at 60% of the speed of light with respect to Earth for example, then their relative velocity will still be less than the speed of light. The traditional formula for simply adding up velocities doesn't work in this case.No, time will appear to pass slower, but that doesn't mean time will seem to go backwards.If EACH object travels at 60% of the speed of light with respect to Earth for example, then their relative velocity will still be less than the speed of light.

If you were to set up a ship travelling at 80 percent the speed of light if you stayed on the ship for 1 year how many years would pass on earth?
Time slows down by a factor of 1 / square root of 1- (v2 / c2), where v is the velocity (or speed) of the object, and c is the speed of light.
If you leave Earth traveling at the speed of light in a circular pattern and your twin stays on Earth observing you when you eventually reach your twin who will be older?
According to the theory of relativity, time dilation occurs as an object's velocity approaches the speed of light. As a result, time will appear to pass slower for you as you travel near the speed of light compared to your twin who remains on Earth. Therefore, when you eventually reach your twin, they would be older than you.
Does time exist at the speed of light?
At the speed of light, time does not exist as we understand it. According to Einstein's theory of relativity, time slows down as an object approaches the speed of light, eventually coming to a stop at the speed of light. This means that for light itself, time does not pass.
