This question already has an answer here:
From what I'm understanding, the Speed of Light is roughly 186k MPS NO MATTER WHAT!
Then say if a bean of light shoot pass near a Black Hole (Outside the Event Horizon of course) 1k lightyear away to us, it will take 1k year for us to reach us.
But because of the Gravitational Time Dilation, a year near a Black Hole will be a thousand year for us, so for some observer near the Black Hole, the same light reached us in only a year! Thus it had traveled at the speed of 10c!
Then if the Speed of Light is STILL 1c for the observer near the Black Hole, then it would be seem to us only travel at .1c!
Theoretically the light will take a thousand years to reach the destination for both observers, but a thousand Black Hole years will be a million years for us!
Unless for the Black Hole observer, we are only "a light year" away!
I can't wrap my head around this! Somebody PLEASE be so kind and explain it for me!
Much much appreciated!!!
