Big Rip theory

Endless Void or Big Crunch: How Will the Universe End? | Space Here is a link to the theory about the big rip. I just want to see what others may think of it. It says implys that the universe including Earth is continue to increase its acceleration not just a constant acceleration or slowing down like you might think it should if the big bang happened the way it did. It also implys that it is not the appearance of acceleration between galaxys.

Well basicly according to the laws of conservation of energy and thermodynamics, energy can not be created and also energy that exists goes from a state of reduced entropy to a state of entropy (order to disorder)and one day there will be a state of maxium entropy or heat death (non usuable energy) So what is causing these galaxies to increase its acceleration, in my opinion it couldn't be the big bang because according to those laws the acceleration would stop and it would continue at a constant speed or constant acceleration unless acted apon by an outside force. Not increasing its acceleration like this article states. So as it bumped into other matter some might accelerate while others decelerate. Not all increasing its acceleration together.Also one of my questions is that when I commented on galaxies more tha 3MLY away are moving faster at signifacnt fractions of the speed of light. I was told by crashfrog that it is only the apperance of acceleration not actual acceleration. According to this big rip theory that all matter will one day accelerate so fast that even the bonds on the atomic level will break apart. That doesn't sound like the "appearence" of acceleration. How could appearence of acceleration cause atomic bonds to break. It sounds to me that these galaxies are actually moving that fast.This message has been edited by kallcium, 03-01-2006 12:34 PM

Ok thanks. Thats what I thought. So out of curiousity what is this new scientific princable that is being theorized if indeed the galaxies are increcing their acceleration?

How does anyone know that the big bang is the way you described? To me it requires faith that it doesn't follow the the laws of physics. Very little is known about dark matter so it is hard to really say what it will do.

Thanks Chiroptera, that is very interesting, I will have to research more about it.

So in my conclusion, for me it takes faith to believe that God made the universe and caused it to accelerate the way it is, just is it requires an "equal and oppisite" faith the the big bang took care of that with the help of dark matter.

ok fair enough

Honestly how can the universe be infinatly hot and dense at one point? There has to be a finite point to that. If it were infinitly hot and dense then today there would be an infinate amount of energy (heat is energy) which there is not as stated by the laws of thermodynamics. If it were infintly dense then there would be an infanite amount of matter to keep making it denser, which there is not. There is a finite amount or energy and matter. Matter and energy can not be created nor destroyed. If you believe the universe was at one point infinately dense and hot, then came to a point in time in which it became a finte amount of heat and density, well then that takes a whole lot of faith.

Yeah actually the therory about the big bang is I believe that matter is eternal. That takes as much faith to believe as there is a supreme being that is eternal.
