How about the gap between us and Andromeda? You think the gravity between us and Andromeda is enough to overcome space expansion AND to drag us together? Remember...Andromeda is 2,500,000 light years away!

You seem to be confusing the expansion of space and the expansion of matter. Gravity isn't affected by the expansion of space. Gravity is proportional to mass, the only thing that affects gravity is your proximity to it (and that's more how it affect YOU). The bigger something is, the farther away you have to be away from it to escape its effects, and the bigger the object is that is trying to get away the harder it is going to be. For example, Earth is orbiting the sun because of gravity and it would take a lot more force for it to get away than if you yourself were in space trying to move away from the sun.

While space is expanding at a rate greater then light (matter), the matter in it is moving much slower. Compare it to two cars racing. One car can be going faster than the other without directly affecting the other. Relative to each other one only seems to be moving a little faster than the other, but to someone watching both from far away they are both moving pretty fast. Now, we on Earth are orbiting the sun, which is kinda the same as the way the rest of the universe works. Moons orbit planets, planets orbit stars, and solar systems fit into a niche in a galaxy in which all the stars are orbiting a central black hole (in out galaxy at least). As far as we know galaxies aren't orbiting anything, they are what are moving away from each other. Everything inside the galaxy isn't really moving away from each other because the gravity, whether coming from a planet, star, etc. it holds it in place, aside from debris in which their momentum keeps them from being captured such as meteors. Now the gravity of a galaxy isn't going to be too noticeable to a small object in space, but its pull on another galaxy is going to be quite formidable. Just look at all the stuff the gravity from our sun is able to catch, now imagine what the gravity from our entire GALAXY is able to catch. It's no big feat for the mind to see how even though Andromeda is 2,500,000 light years away that it can still catch it, it's a whole galaxies worth of gravity!

I hope that answered your question. Sorry if it's a little confusing, it was kinda hard for me to put it all into words.

one of the places you can see these effects are at the edge's of galaxies. The suns at the outer edge of them are orbiting around thier galaxy faster than they should be (farther from center the slower they should orbit around thier sun). From what i've read and seen the claim is that it is dark energy or dark matter that is making this true. Also they think one or both of them is why on the universe scale galaxies are all in particular "veins" in spacetime.

really wishing I would have kept a link to all the you-tube video's I've found. Last set I watched was about the various people that tryed to work out infinity and how several of them ended up going insane trying to work it out.

So how am I seeing it now? It should have passed me LONG ago...long before we were even here. Long before the earth had even formed, the sun had formed.

Maybe there is a "cool down" time involved after the initial burst? I have never saw any type of exlplosion that vanished just as quickly as it had started. Due to the size of space, maybe we are just finally now seeing the final stages of the explosion and resulting cool down.
