I have often wondered these things. Please keep in mind I am not an astro-physicist. I do not dwell in the confusion of enormous math equations to somehow prove all things. In my simple mind, I know that a calculator does not "know" that 2+2=4, you have to program it to tell you the answer you desire. Therefore, in my simple minded thoughts, I am not going to go any further mathematically than that equation, because I don't feel that any math problem will explain my existence. So, beyond theories of relativity and quantum whatever, and whatever math symbol leads to a big bang, here are some simpler things I would like to know:
1) If the universe is estimated to be 13.75 billion years old, based mostly on the age of objects in it, how can something be 10 billion light years away? Wouldn't that object, if starting right from my back yard, need to be traveling away from me at nearly 75% the speed of light to get to its location where it is producing the light that returns to my back yard? That's not even considering the objects that are directly in the opposite direction the same distance. How would they get 20 billion light years apart in only 13.75 billion years?
2) Everything rotates. From the water in my toilet, the moon around the earth, the earth around the sun, the solar system within the milky way. But the universe doesn't? It expands in a straight line away from a single point? That big bang thingy, right? What is that? Can't explain something, so come up with anything that makes no sense, because nothing else makes sense either? What if the universe rotates too, like everything else, and that red shift explanation for the expansion of the universe is simply because we are closer to the middle, spinning faster that the objects on the outside, and they appear to be moving away from us? Like Jupiter would look to Mercury as it moves around the sun ahead of it. But then again, if I was paid to produce something that I couldn't quite figure out, I would come up with some hair-brained idea that nobody could refute because they couldn't do it either.
3) Black holes? A big hole in space where matter gets pulled into and never gets seen or heard from again, but doesn't cease to exist either. Another idea that if you make it so complicated, nobody with doubt it. Sounds good to me, sign my paycheck please. Maybe they are just big iron balls that have such intense gravity that their atoms are crushed into an area that can't move. No movement, no heat, no light. Black! It's not a hole, it's a solid ball. Something gets pulled into it, and it just crushes into the surface and becomes part of it. No big fancy endless pit, just a simple ball.
4) Dark matter, anti matter, parallel universes, wormholes. To complicated. It's all way more simple than it made out to be. It doesn't need to be complicated just because you can't explain it. Just because the person trying to figure it out is smart, doesn't mean it takes a smart person to figure it out. Maybe the simplest idea is the right one. We are just here. Why? Who knows.
5) Life. It's everywhere. It has to be. Why? Because its here. If its here, it's everywhere. Throughout the entire rotating, non-big bang evolved, uncomplicated, unexplainable universe, there is life. If for no other reason that purely by accident, there is life.
Thank you for allowing me to ramble. I'm sure most will disagree, and call me an idiot. I bow to those, and will agree with you. I'm no genius, but I can guarantee this, I know for certain, just as much as you.
