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.
What is the speed of light in time?
The speed of light contains distance and time, it compares how far a photon goes in a unit of time. If I understand you correctly, you are looking to compare such a relationship to time once again. Like a hypothetical spaceship traveling faster than the speed of light. If it travels one light year in a day instead of a year, that would be a light-year per day, or say, 365 lights.
What is the approximate time it would take to travel a light year?
if you are going the speed of light, it would take 1 year.
Is light year per hour is a measure of speed?
Well... yes, but it's not a very useful one. Light travels one light year in... one year. So the speed of light (which you cannot accelerate to) is about 1/8766 light years per hour.
How far is 9000 light years?
900 billion years - if you travel near the speed of light. If you travel at any slower speed, it will take longer of course. But do some reading on time dilation - if the traveller travels at a speed very near the speed of light, from his point of view it will take much less time.900 billion years - if you travel near the speed of light.

How has the idea of light years changed over time?
this can never change, light travels at a constant speed, a light year is the distance light travels in one year.
How many km can the speed of light travel in one year?
One one year's time, light can travel 9.4605284 × 1012 kilometers.
A light year is equal to?
Well depends.. If you're saying that the speed of light is 3x10^8 m/s then 1 light year is 9.46728x10^15 metres If the speed of light is exact (299,792,458m/s) then 1 light year would be 9,460,730,472,580,800 metres (9.46073x10^15) Not much difference...
Is time faster than he speed of light?
This is an unanswerable question, since time is a dimension and the speed of light a measurement. The two are directly related, however, insofar as approaching the speed of light inversely affects the relative speed with which you travel through time. For instance, one year on a spaceship going 99% the speed of light (it is impossible to reach the speed of light relative to local space-time, in that paradoxical scenario time would stop completely) would cause you to return to an Earth that has aged hundreds or possibly thousands of years (I'm not sure the precise speed to time conversion formula).
When do light years become greater?
A light year is the distance covered by light in a year. So a light year is greatest when the speed of light is greatest: that is, in vacuum. However, since much of outer space is near vacuum, a light year is near enough a constant measure.
What is the distance traveled in a year at the speed of light?
It is known as a light year.
How much energy is needed to travel at the speed of light?
It is not possible for any object with any mass to travel at the speed of light. It is possible to travel at 99.9999999999999999999999999999999999999% the speed of light, you could even travel at "99.9 followed by a trillion trillion 9s"% of the speed of light but never quite 100%.According to our current mathematical theories, for an object with any mass to travel at the speed of light it would take infinite energy to attain that speed.
