As far as I am aware of the current and accepted theory regarding the size and structure of the universe, based on Hubble´s insights, says, that space is isotropic: that means at any place in the universe an imaginary observer would get the "same picture" - that implies also the same rates of expansion and red shifts. For example: the picture we have from the universe relates to our specific view on earth. From here, for example, we can observe galaxies in more than 10 billion light years distance. So now let us place this imaginary observer exactly on a planet in one of these "border" galaxies (from our point of view the most redshifted one). What exactly would he see? Isotropy says: the same as from here. So he would see our galaxy, 10 billion light years distant, red shifted. But if he saw into the other direction, he himself would, again, see galaxies in about 10 billion light years distance (i.e. 20 billion lj from earth). And on these galaxies another observer again...so resuming this would imply that the universe, and with it matter, is infinite and never-ending. Is this understanding correct? Now let us focus "back" to the imaginary observer in 10 billion lightyears distance from here. We would see him, and the largest number of objects between him and us red-shifted, that means expanding or getting more and more distant from us. However, when he watches "towards" us, he would see the same thing, i.e. everything between moving away from him towards us. But isn´t there a contradiction implied? How can be explained that everything between him and us is getting more and more distant simultaneously from him and us? Thanks in advance for the replies.
