Houston ah we have a problem.
As far as punching holes in any theory, sure. If I say I am human, and you say prove it, and then do not accept any evidence as proof, then you may think you have punched a hole in my theory of humanhood, but you just are doing sophistry. I know Andromeda is a galaxy, I know we have actually seen supernovae in other galaxies. If you choose not to agree, then perhaps you could show me your evidence that better explains what it is, and we'll put it through some repeatable tests. You just can't say, "No it isn't." That is not an argument. (That whole Monty Python thing just flashed through my head..."No, no, no, this is getting hit on the head!")

I'm glad we have so many people that are educated and knowledgable in so many different fields of life and science posting on this board; and that they are willing to take the time to inform and educate the rest of us.chiefdanfox wrote:OK, I am screaming this as I am running away screaming...ygmir wrote:It's all based on theory.......IMHO.........

The speed of light is and has remained constant over observable time. It fits with our calculations, which allow us to drop planetary probes on distant planets, keep satellites in orbit, send missiles through Iraqi windows, ad nausea.
Time is not constant, and is affected by gravity. We use this principle every bloody second of every day with our GPS satellites. They take into account not only the delay of the distance from the receiver, or surface, but also that in their orbit, they exist in a slightly faster time continuum. This is called frame dragging. Massive objects have a pull on the fabric of space, and they tend to slow time around them. This is repeatedly tested and proven, and so far, nothing has been offered to refute it, that is testable, repeatable and better explains what we are seeing, measuring. That does not mean that nothing ever will, it just means nothing better explains observations. Science is open ended. Had we found but one refutation, against all of this overwhelming evidence, we would have to toss it, and find another hypothesis to use and test, leading to a clearer theory or understanding of how things work...aaaahhhhhhhhhh
So how does anything move 93 billion light years (or even half that) in 13 billion years? The stars have to be moving at a relative speed greater than the speed of light.chiefdanfox wrote:Well, the way it works is we can see roughly 14 bn years of light, so we have a diameter of 28 bn "visible".

chiefdanfox wrote:OK. I am going to try one more time. That 13.7 by means the observable universe. That is the oldest light we can see, it is very red shifted. We have seen this most ancient of light, and our best knowledge says prior to that time, the universe was so dense (compacted), that photons could not move through. It was opaque. That red shift is used with the Hubble Constant to calculate distances.
For starters, the current number is 13.7 billion years old for the observable universe. This is a radius, right? I look north for 13.7, then turn around and I can see south for 13.7. the math adds up to: 27.4 billion of observable. OK this goes on in a sphere. Up, down, left, right, yes, front and back, and every conceivable angle in between. So Image you are in the center of a sphere, that has a diameter of 27.4 bn ly. Any direction you look, you can see 13.7 bn yo into the past. That is the observable universe.
OK there is a thing called comoving distance the Earth sits from the "edge". In that 13.7 bn years (time, not distance), that measurement is the comoving radius, so imagine you are in the center of an inflating balloon holding the man side of a tape measure, and the fucko side is taped to the wall of the balloon. You see the distance growing: Comoving radius.
Ok that is still not enough, since most folks think ok, I got the 27.4 bn ly thing, and I also get that in 13.7 bn years we have moved, but to get to 93 bn ly across? "WHERE'S MY BIBLE?" Hold on to yer robes and rosary, Peter, I am getting there.
First off we more or less have measured the speed at which the OU has inflated and it is about 50 miles per second per 3/14 million ly, the so-called Hubble constant. So if you can pull out your Newtonian physics and do a a rate of falling calculation, you are going to get a really big number, way bigger than 27 bn ly across. "BUT", Michael paddles in, "It still ain't 93 bn ly, you heathen monkey-boy."
Well, we launched a satellite that took a series of measurements of this first light (they are actually microwaves), and those calculii (may I say that word, calculii? no...) gave us a pretty good idea of the of the factor we need to use to figger out the scale of the expansion. That factor is about 1300. So the universe has expanded 1300 times since first light. The cosmic background, this observable wall of light emitting matter, was 1300 times closer when when the light we see now was emitted.
If nothing was in motion, that light would have been observable to the matter that eventually made earth about 36 million years after the big bang, but since the universe was expanding at 50 miles per second per 3 1/4 million light years, it has taken a while for that light to finally catch us. I am running 6 miles an hour, and Satan is running 7, I have a 20 mile head start, how long before Satan catches me? AND how far will I be from Satan's starting blocks (BTW, his blocks are VERY Steampunk).
On top of all of that, the Universe is very, very curved, not flat, Einstein, so simple geometric calculations will render nonsense. It is like drawing a triangle on an uninflated balloon, and measuring it, then inflating the balloon to twenty times its volume and thinking that the hypotenuse will be h X 20.
I thought everybody knew this.
