Do you know what causes red shift? A attractive force, Gravity. We can observe it when we look at waterfalls and barrels tied together going over it.
What is the invert of the shortest measurable distance of light? Now invert Max Planck`s measurement.
10 to the power of 22 lightyears
So we now we know the longest measurable distance of light, we need to surpass that with our telescopes to make the observation that nasa has stated.
But I am bumping this because the picture I posted got deleted for some reason
I am serious we are all heading towards something, everything we can observe. The space is not expanding, It just appears that way. I think we may be going faster than the speed of light towards it.
