Accelerating expansion of the universe?

Excellent question. I have a theory that could explain the appearance of an accelerated expansion, but it would be in a distinct pattern. It doesn't need any exotic particles, unknown forces, or break any laws of physics. Only one expert would talk to me about it. He told me they have only found 6 galaxies that showed evidence of accelerated expansion. Not enough to show a pattern. I hope to publish my theory this year. I need someone really good at math to check some things first.
