Being somewhat addicted to learning Physics, Biology, Chemistry and Astronomy, I often find myself confused, even baffled. While I try working most of
these issues on my own, there are some where I end up drawing a blank. This is one of them.
If I understand correctly Mr. Hubble discovered and documented the astronomical equivalent of the Doppler effect a.k.a. the"red shift". From his
measurements he deducted that the further away the object was the more red-shifted it's emitted light was, hence the expanding universe model was
My problem with this is, if all the stars or galaxies are racing away from each other due to universal expansion, how is it that the Milky way is
currently colliding with other galaxies
bound to collide with Andromeda in about 4 billion years?
Doesn't that prove Hubble was wrong? I mean if all galaxies are supposed to be racing away from each other than none of them should ever collide with
any other... or am I completely wrong in my thinking?
Kind regards, M.
