Red shift occurs when a source of light is moving away from a viewer's perspective, and blue shift occurs when it is moving towards a viewer's perspective. According to the Big Bang theory everything is moving outward and away from everything else, yet the blue shift occurs as the Andromeda galaxy comes closer to us every day. How can this be?

I got this right, right?:

Think of paradoxes. The universe is full of them. Their must be something within our own galaxy (probably a certain gravitational pull) resulting in the movement of the Andromeda galaxy towards our own. Then again, I wouldn't know for sure :P

Or, try this.

Or it could be we are closer to the center of the universe and we are in a more perfect orbit around whatever it is that has the most mass in the universe and the andromeda galaxy is getting pulled in faster than we are.

We know this isn't true, as year after year the planets in our solar system revolve around our own sun, so planetary and solar bodies are clearly not just moving in one direction - outward from the initial point of explosion.

I'm not sure where you got that particular statement, but I'd love a source to be cited.

"Anyway it's quite natural for galaxies to collide even though the universe is expanding - although I could see why you might get confused about it. What happens is that there is a battle between the forces of gravity between the two galaxies (which is trying to pull them together) and the expansion of the universe (which is trying to pull them apart). With galaxies that start out quite close together, it is almost always gravity that wins, so in the end the galaxies will collide. This will most likely happen to the Milky Way and the Andromeda galaxy (our nearest large neighbour) in a few billion years."

Oh I am not confused. Just pointing out a major flaw of the theory. If gravity is pulling them together then there is no reason that they would have gotten so far apart to begin with.

I doubt you've even read the theory. Produce a link to support what it is you had to say or you're just babbling nonsense.

NO, the only flaw is in your OP. Everything is not moving away from everything else - I can walk up to you hypothetically and poke you in the eye. I wouldn't be moving away from you. Blue shift occurs on Andromeda because it's supposed to - Andromeda is moving toward us.

How is it creative thinking when you just snatch things from websites?

Andromeda is moving toward us


According to the theory it should not be.

Who said anything about creative thinking? Being right is more important than being original.

But you're not creatively thinking. You're speaking to a theory someone else came up with, but you're not showing your work. Perhaps you can show a website or provide a source that you're making your criticism of. Otherwise, it just looks like you're making up your own version of the Big Bang theory so that you can poke holes in it, since you can't actually poke holes in the *real* theory.

Ever heard of gravity?

And what scientific basis do you have to make that conclusion Pau1?

If gravity is pulling them together, then it should have stopped them from moving apart from each other to begin with. Fairly simple.
