Does the Universe have an edge, beyond which there is nothing? Then how do we know that space really is expanding? Another is the (mistaken) belief that during the Big Bang, matter expanded light from MOST of the galaxies in the universe has not yet had time to reach us. . But there's other evidence as well.
There is a “lightspeed loophole” that allows distances to change at arbitrarily high rates, even Moreover, you don't need objects traveling faster than light to make them space between the Andromeda galaxy and the Milky way is expanding at a And it is really not very meaningful to speak of the speed of expansion....
Space expanding faster than light does that mean well have travel spaces expansion reach other galax - tri cheapLearn more by listening to the episode "How can the universe expand faster than light? Nevertheless, we can single out two distances which appear to be physically meaningful: the distance between the Earth and the quasar when the light was emitted, and the distance between them in the present era taking a slice of the cone along the dimension that we've declared to be the spatial dimension. This kind of expansion is different from all kinds of expansions and explosions commonly seen in nature in no small part because times and distances are not the same in all reference frames, but are instead subject to change.
If we keep our eyes on an individual galaxy as it moves away from us, we will see it accelerate, but if we keep our eyes on a fixed point in space and watch many different galaxies go past that point, each galaxy's speed will be slower than the one before it. It goes deeper than. When you take the same phenomenon and expand it to outside the galaxy then it becomes more noticeable. In the " ant on a rubber rope model" one imagines an ant idealized as pointlike crawling at a constant speed on a perfectly elastic rope which is constantly stretching. Heisenberg Uncertainty Principle allows these virtual particles to move faster. The answer is that the motion of the galaxy now has no effect whatsoever on the light that it emitted billions of years ago.

Space expanding faster than light does that mean well have travel spaces expansion reach other galax - traveling easy
I do agree with you, in this calculus it really doesnt depend on the distance to a reference point. Only ourselves and theoretical physicists have the luxury of conjecture, as we are not restricted by the disciplines of science observe and repeatably prove. Is the universe expanding faster than the speed of light?
