So unless you can account for every gravational anomaly between here and the galaxy being examined the best one can do is make a wild guess and have faith that there are not any unforeseen variables in the hundreds of gallizillions of miles being accounted for.(July 17, 2013 at 2:09 pm)Drich Wrote: Therefore, light can not travel at the same speed when affected by a black hole meaning the equasion used to caculate one light year (The standard unit of measure when caculating distances between galaxies) will be wrong.
It seems to me that the only possible effect would be to slow the speed at which the light is travelling, so that ages are longer and not shorter. In other words, if Andromeda appears to be 2 million light years away but gravity is affecting the accuracy of the measurement, then the light from Andromeda may have been traveling for 2.5 million years?
