by measuring redshift physicist conclude
1.most of the galaxies are moving away from our galaxy
2.universe is expanding
1.most of the galaxies are moving away from our galaxy
if we ride alongside a train on a motorbike with relatively same speed , do we don't hear the doppler effect . it is effective if one is static
like wise our galaxy must be moving alongside or in line with other galaxies so shouldn't there be blueshift on the direction of our galaxy heading and redshift on opposite side, but we see redshift every where
2.universe is expanding
how physicists concluded universe itself is expanding by judging the outward movement of galaxies universe is infinite ,isn't it? so how does universe expand .if space itself is expanding from a concentrated state stretching stuff within it, then one has to admit space is finite ,if space is infinite it must not be expanding.
if galaxies are moving away from each other ,well they are moving relative to each other but how does it prove space/universe is expanding
