But also something to concider also is the clasic model of an expanding universe beiong a baloon being blown up. where stars are drawn spots on the
balloon. I'm sure you have seen this description before.
But in this example as the baloon expands so do the dots.
This analogy is wrong. The galaxies do not expand as internally they are gravitationally bound. A better analogy would be a balloon with small labels
sticked to it.
My point is, if Space is indeed expanding then all space should be expanding and matter itself should be becomming less dense.
On a universal scale, yes, matter becomes less dense. On a galaxial scale, no, matter density remains the same (as result of space expanding).
The other thing to consider is if all space is expanding at the same rate then matter would also be expanding at that rate and we would observe
a static universe.
The universe is shrinking and but at smaller scales space is shrinking faster.... Wouldn't that also look exactly like an expanding universe to
That is pretty much a case of perspective. From our perspective, the galaxy is expanding. And since our perspective is what matters to us, it is a bit
of a useless exercise to imagine what the galaxy would do from the perspective of an imaginary observer.
As for your idea of matter shrinking instead of space expanding, I think it is not a correct perspective, as it would mean that the distance between
stars in a galaxy or the distance between the sun and earth would also increase. Which is not the case.
