horro business thats exactly how i feel. you cant use human logic to explain god our heads would just explode. and man i have tried the bible is a big story book, fully of useful ANALOGIES to live your life well. not a book of out and out rules to live
peace brother

i'm not trying to be rude but most of you seem to know very little about the big bang and should at least read up on it a little before you comment. i couldn't make it through this whole thread but i'll comment on some of the misconceptions i read.
1. from our current understanding and evidence, the universe is not going to collapse in on itself. space contains dark energy (we do not know what it is but we can measure it) which has a repulsive force. as the space between galaxies become larger so will the dark energy repulsive force, causing the galaxies to accelerate at an increasing rate.
2. we only know what happened at 10^-43 second onwards. our theories don't make any sense when we put in t=0. the main reason for this is because we have two conflicting theories, general relativity and quantum mechanics. general relativity is good and describing things that are large and heavy while quantum mechanics is good and describing things that are very small and light. the problem is when something is extremely heavy and also extremely small such as black holes and the big bang. to come up with a theory that marries these tow is the holy grail of science and has been called the theory of everything (or the unified field theory to be technical). we've made some progress on this such as string theory, unfortunately there is not a test that can falsify it so we still have a ways to go.
3. there is a lot of evidence for the big bang. the first was discovered by Edwin Hubble who saw that all galaxies are red shifted meaning they are all moving away from us suggesting that if you turned back the clock all galaxies would come from a single place. the second big discovery and the best evidence for the big bang was made by bell labs (this won the discovers the Nobel prize). they built a radiometer for astronomy and satellite communications but they notice something strange, everywhere they pointed it there seemed to be a constant uniform source of microwave radiation. at first they thought it was faulty equipment, then thought it might be the birds in the radiometer after discounting all of the possible problems with their set up, they realized there seemed to be microwave radiation coming from every direction of space at the same temperature.
to understand why there is a uniform radiation permeating space (called cmb or cosmic microwave background radiation) one must understand what happened a trillionth of a trillionth of a second or something like that after the big bang. the following is our best understanding of what happened.
the universe started out as a minuscule point smaller than an atom. it contained some twenty pounds of matter, the rest was energy. this point was trillions upon trillions of degrees hot and for some unknown reason it exploded for lack of a better term. this energy spontaneously turned to matter as according to e=mc^2 (energy=mass*speed of light squared).this energy turned into matter and anti matter. for those who don't know what happens when matter and anti matter get together, they annihilate each other releasing a very large amount energy in the form of light (to give you an idea of how much energy is released from matter/anitmatter reaction, only a few grams of antimatter would be needed to send the space shuttle into orbit).
so a split second after the big bang there was a tremendous explosion from the matter and anti matter annihilating each other. luckily for us there was more matter than anti matter or we wouldn't be here today (that is also a great mystery why there was more matter than anti matter). all this energy created from this explosion continued to expand with the universe. due to ever increasing space this light was stretched becoming a lower and lower wavelength until we reach today some 13.7 billion years where it now peeks in the microwave range. i find it incredibly amazing that this explosions was so huge that we still see the remnants 13 billion years later.
this was an extremely simplified version of events but i hope it shed some light on what happened.
of topic reply to natureisawsome, have you ever taken a biology class jesus i've never seen such ignorance in one post. you site the laws of thermodynamics but what you seem to not know is that this applies to a closed systems, earth is not a closed system. evolution is one of the most well documented scientific theories we have. the evidence is endless; Neanderthal, Australopithecus, homo erectus, cro magnon man, endosymbiosis, drug resistant microbes, fossil records, dna evidence, living fossils, vestigal structures, carbon dating, radiometric dating, the list goes on and fucking on. even the god damn pope accepts evolution happened. have you ever looked at the evidence at any other websites besides imanidoitwhobelievesincreation.com and evolutionisthedevil.com?
don't bother replying, you're blocked. if it's one thing i've learned is not to argue with a creationist, they site faulty claims and ignore any evidence you put forward.
hey dude do you know the name of the species that was around before homo erectus that had a larger frontal lobe than us and was significantly physically stronger.
i remeber reading a chapter about them in a text book basically stating that man and this species where together and man managed to train canines to an extent that they hunted for food and drove them out of extinction.
i know im not making itup, but i cant find alot on it
cheers ali
ps lol, i love the bell labs story. that they teted the hole thing for a year. cleaning it and killing pidgeons all around so that there was no interference
maybe your thinking of neanderthals which were around at the same time as modern humans and is thought that we may have drove them to extinction. but this is all after homo erectus went extinct. they were stockier and had more ape like features like a large brow ridge.

yes that was a great story. they cleaned out all the bird shit and everything lolQuote:

Before homo erectus was homo habilis
don't forget homo ergaster :)
all those homos (befor human) were just yetis (sasquatch) they werent my grandparents
