Science claims the universe is expanding

What evidence does science have, that explains such, said the spider to the fly. :-)

    Apr 4 2013: If we accept that the red-shift observed in the light from other galaxies is evidence that those galaxies are receding from us (It's fairly safe to do so as red-shift is used in other areas such as identifying binary stars successfully), then the evidence suggests that almost all observable objects are getting further away. If you have a group of objects that are all getting further away from each other then the group as a whole must be gradually taking up more space ie expanding. The caveat is however that this theory and observation suggests the observable universe is expanding. We can't apply this to things we are as yet unaware of.
    They must be fairly confident. They don't name space telescopes after just anybody.
    • Apr 4 2013: Congress and local governments christen whomever they choose, while they stand in the open taking bribes, to keep their jobs and enrichen themselves, while destroying the moral fabric of this nation. Gosh, they named a telescope after someone. So as andromeda is in blue shift, that means nothing to you?

      So tell us, can this telescope see to all that is out there? What if most that science sees is in red shift, what if all not seen is blue shift?

      I have often wondered about this. Considering how little we actually know about intergalactic space, it seems to me that cosmologists are making a big assumption, that the entire red shift is due to the speed of the receding galaxies. To the best of my knowledge, every bit of data regarding the behavior of electromagnetic radiation has been gathered from within the solar system. To me, it seems completely plausible that the red shift could be due (perhaps only in part) to some other natural attribute of intergalactic space which we have no way of being aware of, until we send something out there.

        Apr 7 2013: Red shift observations have been used to measure other movements such as relative velocities of binary stars or even the rotational velocity of a single star. As a technique it has proven reliable in several different situations. Even if other unknown factors contribute that wouldn't change the fact that the vast majority of large scale structures are moving away from us.
