The Theory of "I Don't Know"

Maybe, just maybe, the universe is not expanding like everyone presumes? I don't know, but I wonder.

1. Everything in the universe began in a infinitely small spot that blew up in the Big Bang - darn, hard to get my head around that
2. The further things are away from us, the faster they are moving away, in every direction - hmmm, curious

We don't know the answers to these questions, but there are many theories and speculation. Our mathematics break down, and therefore our understanding .

While I have no idea what the answers are, I do have a question. Sometimes there are simpler answers to complicated questions. Sometimes it's the assumptions that are made.

Question: What if …

Light curves through warped space, around dense gravity, through dark matter, other unknowns . Maybe over astronomical distances, the frequency of the light waves get affected? Minutely lowered? To the point we can't detect it yet? Maybe the space time continuum stretches out those light waves just a tiny bit (had to throw that in)?

All these theories have a common assumption, a large assumption. That is the doppler effect. Maybe there is some other effect out there?

I don't know … but I wonder …. what if …
