On other boards, I would agree; but not this one.
It reminds me of the quote: "I may not agree with your opinion, but I will defend to the death your right to voice it." I feel the term 'opinion' is key here. That was not an opinion. I intend to drop the subject.

As to the possibility or impossibility of ever knowing what occurred before or at the beginning of the big bang if that model is correct:
First, I think the model is correct as far as it has been described which is back to a particular fraction of a second after it began. Second, conclusions about a precondition can be correctly drawn from the state of something now, so I don't hold to the premise that, 'we can never know'. We may in the future discover other universes and thereby learn more about ours.

Hi guys. How are things?
I've heard it said that the Big Bang theory does not deal with the actual explosion. OK, so the explosion is something separate. I gather that the Big Bang theory itself would then refer to the theoretical formation of stuff after the bang. My arguments concerning thermodynamics and dark matter mostly deal with this anyway, and the explosion is naturally closely related, so that also should be discussed. Tobin Dax (I'm a fan of DS9), you mention that dark matter, should baryonic particles and neutrinos be so classified (I know nothing about either) still is not enough to account for gaps between galaxies. The universe is obviously uneven, with galaxies in one place and expanses of vacuum in another. This does not square with formation from an explosion, after which the universe should be of uniform density. Musashi: Matter being outside of time does appear to be the general Big Bang explanation in the first place. The reasons for its appearing from nowhere and suddenly exploding for no good reason - yes I know you have said that is not part of the theory, but the theory depends on it - would appear to be nonexistent. God is not 'sidestepping' the rules by being outside of time. Naturally this is a matter of belief, but being eternal as the Bible says, that is His basic status. Someone else brought up the subject of why we Christians must interpret the Bible literally, and why we can't put both it and the big bang together. Firstly, it's because we'd rather believe what God says, and the six-day purposeful creation outlined in Genesis (along with the genealogies, which add up to several thousand years) directly contradicts the big bang theory. There is a much more important reason as well. The Bible reports that everything was perfect before Adam sinned: Quote:
So, the big bang and the entire evolutionary theory completely contradicts every facet of the Christian faith. TruthSeeker: The Bible also says, Love your neighbour. Please do be polite. This is supposed to be a place of amenable discussion. |

What doesn't make sense then, is why so much evidence exists that the creation account in the Bible isn't true. You note yourself that, "We see diseases such as rheumatism in the fossil record, as well as animals buried and some in the middle of having lunch". My favorite contradiction in the Bible from the original sin story is that women were to be punished for sin by having to bear pain in childbirth. So did god come along and invent anesthesia 1900 years after Jesus for any particular reason? I know this is getting away from astronomy, but I bring it up because it's less questionable than arguing against the science of dating techniques or BB theories. In other words, it doesn't take a science background to understand the weight of the evidence.

I don't understand the logic behind the thought that if the universe were created by an explosion that it should be uniformly dense. Explosions rarely ever seem to be uniform. Large chunks fly this way, small chunks fly that way. If the universe was the result of some violent explosion then the our current model seems quite reasonable.

........hmmmm.....
..... ... .....hold on.... .....let me drink some coffee first... ... .... .....aaahh!..... .... ..ok... ... .. so.... why is it that a belief in a certain structure of religion would have anything to do with why and how our universe moves or expands or whatnot? The age of the earth is most definitely older than 6 thousand years, and we have records to show this... WE HAVE RECORDS TO SHOW THIS... we have recor---- oh... i said that already... =) **sip coffee** anywayz... This CMB, a big cosmic microwave background of sorts... it has an appearance of being smooth from our perspective... but, from another perspective, as in being infront of the so-called expanding wave of the CMB, the form of the CMB may be totally different from what WE see... The aforementioned bits and pieces of debris flying aorund, that would be on the OTHER side of the CMB that we are seeing... not on this side... the unevenness that we may see throughout our universe is more than likely caused by the formations of gravitational singularities that had formed either by the CMB expanding or by amounts of Dark Matter/Energy being present before the CMB commenced its journey... Our universe as a whole could have been a certain charge at first, be it negative or positive... and an opposite charge could have been introduced that caused the reaction prior to the BB expansion.... or there could have been a plentiful amount of negative and positive amounts of matter/energy everywhere but with no force to conduct their charges together to cause the BB, so a certain element could have been used to help that conductive charging of particles... like a 9V battery.... stick your tongue on one tip, either negative or positive, one at a time, and you get nothing.... but stick your tongue on both charges at once... OI!! We do have very old particles that are still around, that were around even before the birth of our world, just floating in space... pockets here and there, empty voids of matter with nothing to do but be pushed and pulled... any mixture of certain particles that might create such a CMB could have been used to excite the BB into reality... .. . . .. ...and about there being a Creator to all of this... well, of course there is!! You think we are here just because? If we are learning what it means to have a mind and a will and an intensely, unending excitement towards finding our origin of birth, than we are most definitely related to something that has given us these wants and needs of understanding and overcoming the obstacles put before us to achieve what it was that our ancestors couldn't... If you recall, the Bible was written just recently compared to the actual longevity of our world... only 2 thousand years prior... within a time when Man could finally use words and the reach of the Holy church to establish a rule of how Man should be.... This was Man's decision to allow the voice of Religion to gain a foothold on the soul's of Man... .. . Man wrote the chapters in the Bible as we see them... and the Church organized it as it saw fit to do... .. even leaving out chapters that have been written by others, but didn't really reflect with what the Church had in mind... .. Religion aside... we are here, and we need to be there... so how do we get there with all the different feelings rolling around inside of us? A certain platform must be established in order for all voices (intelligent or not) to be heard that may have an interested opinion in the matter of why and how... if i die, will i be cast into fire? i most definitely DO NOT think so.... as my parents and church has seen to drive into me since i was young.... but, being older now, 28 as of January, i have finally begun to realize that 1) there is no reason to condemn someone to a life of gnashing teeth and eternal torment if they've done nothing wrong (being that that person is actually a good person).. and 2) we didn't find ourselves to be the center of the universe.... far from it.... literally... as had a certain Text has proclaimed... something does not match up with the words that are written by Man.... the Words that are written by the Creator or NOT the words written by Man.... Man may have tried to interpret a meaning of something shown through their consciousness, as how the Bible seems to be done... but, Man could never fully understand what it is that has created us enough to understand how it was that we were formed.... give these visions of Creation to someone of today's understandings..... i believe that the Bible may look alittle bit different than what we read today.... The Words of the Creator are above us, in the night sky.. in the far reaches of the cosmos.... in the stars... the formation of galaxies... the turning of planets around suns.... the explosions of supernovae cascading their particles all over the regions in which they inhabited... the unknown sources of negative and positive energies that we still have yet to discover their full meaning... Yin and Yang... formlessness... an open mind... a transcendence from a form of solid matter to formless energy, that inturn can create its own matter.... and so on... .. . Be good to eachother... and don't take things so serious that you can't see flaws when they are present, on both sides of the argument... give way when another view may lead to progress... keep morality within reach, but personal beliefs at arms length, yet close to your heart (if it gets you up in the morning, let it)... view from the third perspective, one outside of right and wrong, but one not so distant that you couldn't see the finest details of those lines being drawn.... No one ever mentions the fact that if God created light, then would Satan be the Darkness that we see.... its an argument better left for a time when we can more fully understand ourselves and our universe first... everything is just.... speculation..... and nothing to get worked up over, especially since we have such a looooooooooong way to go... **sips coffe again** ....ok!! =) . ..-={A}=-.. .

i'm not going to take sides right now, but i do recall a certain model that we used in my Earth Science class a couple semesters ago. (it relates to uniformity, hold on!)
imagine the universe as a loaf of raisin bread. a really BIG loaf. the BB theory is sort of like watching the cooking channel--you don't worry about where all the stuff comes from, you just worry about what it does once it's arrived. theories of pre-BB origins are something else.anyway, for the rest of this i'll quote from my book. (yes i kept it...partly cause the bookstore ordered a new edition. darn bookstore! also cause i'm a "nerd" though. :-? ) here goes: Quote:
in the raised loaf, we still see just as many raisins. the "home" raisin is marked, but raisin two is now three times farther away--six centimeters. raisin three is also three times farther away--fifteen centimeters. in the same three hours one raisin moved four centimeters and one moved ten. this is due to the dough growing at a uniform rate of one centimeter an hour (slow bread, but hey). the difference also grew constantly. the original difference of distance was 3centimeters (5cm-2cm). the new difference is three times that--9cm (15cm-6cm). anway, onto the second (and last) paragraph: Quote:
Quote:
all quotes taken from "Earth Science", ninth edition, by Tarbuck and Lutgens. page 622, paragraphs 3-4. now as i said, i'm not going to jump on one bandwagon or the other. Hubble was a pretty smart guy. not to be dismissed lightly as far as i can tell. so is God from what i can tell. i'm sort of stuck in the middle as to how to resolve the apparent differences between them. bit by bit though i find hints. some are good, some awful, still others painful or joyful. science is an ongoing process, as am i. someday i may have a complete answer, but until then i'm going to keep trucking away! anyway, enough of me, your eyes are probably tired of reading by now so i'll let you go--for now. maybe more later if i think of it.

The reason for this is that in an explosion, or in the BB, the fabled 2nd law of thermodynamics forces the formation of non-uniform distributions as a direct result of cooling by expansion. No fancy cosmology required, this common anti BB argument is easily relegated to the dustbin by very ordinary physics. |

Imagine if the BB did result in an even distribuition of matter.
All the creationists would point and say "Look how evenly distributed the universe is, there's no way that could happen naturally"

Does that hypothesis fit with the composition of the Universe? (IE the amount of hydrogen, etc etc?) I don't mean that the mega-nova was a star. I'm not trying to oversimplify things here. The mega-nova would still have had to have originated from something much different than a star. But could it have been the result of a collapse and explosion like a nova?

What I want to know is, what did the lions and tigers and bears (Oh my!) do while waiting for Man to throw out the Original Sin? Hang out at the salad bar? Elmo: This rabbit food is a real drag!

Maybe everyone in Eden just stood around in the sunlight and photosynthesized? Elmo: This standing around in the sun is a real drag!

Well, we could go on arguing about this for several millennia, but I strongly suspect that we won't get far. Face it, we all have our predetermined biases, instilled in us from childhood or otherwise from a very long time ago. We look at someone who doesn't agree with our worldview and think to ourselves what nonsense they're spouting. Something as undefined as the big bang theory, which you have mentioned is not really an explosion, (even though you recently talked about unevenness of explosions when you put forth some arguments) and doesn't really deal with the actual event of the big bang... well, something like that is more of an idea about origins - a concept - than a scientific theory. We all have our ideas about how the universe began, but they're often difficult to prove because they're not observed now.
Given that, I would have to suggest the following fact: Almost all of you postulate the idea that the big bang originated from a black hole of some sort. You may have remembered that we discussed this at the beginning of the thread, when someone said that the big bang came from a black hole and I recalled that black holes come from stars in the first place. The big bang generally relies on a super-dense original clump of matter - a black hole, an object so dense that nothing, not even light, can escape. Thus, all the matter expelled from the big bang could not have escaped in the first place, because black holes suck matter in. They do not let it out. No matter could have escaped the original black hole's gravity well. I suspect that anything as dense as the original 'cosmic egg' would have had the same effect. Regarding the unevenness of the universe, then, a detonation set off in the original clump of matter - whatever it's called - would not have done much more than blast out a cloud of hot gas particles. They would not be likely to start clumping together and form galaxies. Think about it for a while. I'm no astronomer, so don't get too mad for any misunderstanding of physics here, but common sense tells me that the particles of gas, etc., that might have come out of the big bang wouldn't just have started coming together. Think of two hydrogen molecules in space, a kilometre apart. Would they under normal circumstances start clumping together and form a planet? Gravitational attraction does depend on mass and density. Even with something as big as the Earth, the moon's still drifting away, not moulding itself to us to make a bigger planet. Things tend to disorder, not to order. That's the fundamental law of entropy. A special creation - with everything winding down from there, according to laws of thermodynamics - does fit with that. For those who have claimed that no more than a hundred words in the Bible are the Word of God, read it again. Psalms 119:160 says that all His Word (referring the Bible there) is true. The end of 1 Peter says in effect that all the writings in the Bible are breathed of God. Most importantly, the Bible also states that all Scripture is God-breathed and profitable for correction. But that's getting off the subject, excuse me. ops:I know, as you mentioned, that I don't speak for all Christians when I say evolution conflicts with the Bible, but I heartily wish I did.

Cyreks reply:
Jim wrote: Does anyone else see the paradox here? Cyreks reply: Regarding my comments above, there is no paradox here because I do not demand that one has to believe in what I say. I welcome criticism because I believe in free speech. That is why I feel free to comment or explain my concept of scientific evaluation whether it is I or my critic. It is the reasons for the evaluations that are important to me. Tobin Dax wrote: What I want to know is why you consider it is not to be real science. Cyreks reply: Regarding my comments about the ‘big bang’, listed below are my reasons for refuting its scientific concept. Creation out of nothing…… An impossibility. Also, a violation of the laws of conservation. Uniform expansion…… From a starting temperature of 10^32 K to an ending temperature of 2.73 K. How can this be a uniform expansion? Although the uniform expansion started at a temperature of 3000 K, the sudden drop to this temperature from 10^32 K after a brief period of 300,000 years seems unrealistic. Also, after the recombination of matter, the gravitational deceleration would be weakening as the expansion increased. Therefore, the expansion would be increasing rather than being uniform. Every point in space is central to the observer….This concept is made analogous to a two dimensional spherical surface. This is a false analogy. All three dimensional bodies have a common center known as the ‘center of gravity’. That is why a three dimensional body expanding from one point cannot be expanding both radially and spherically at the same rate. Expansion of space….. No reason given for why this is happening. Since there was no explosion, why is space expanding? What is the driving force? Tobin wrote: What is your support of this? I want to know your reasons. Regarding my belief in a steady state, I said the Universe is in a balanced state. The velocities of encircling bodies around a gravitational source will adjust their velocities to their orbital distance to maintain their momentum relative to the central body. Thus, this creates a balanced state. This will remain an eternity until something disturbs that state. Since space is a vacuum, there will be nothing to disturb that state except wayward bodies. Incidentally, my idea of a steady state does not include an expansion or contraction of the Universe. |

Nothing is ever going to change your mind about how the universe is created, nothing short of your god coming down and telling you otherwise. For the majority of the rest of us, all it takes is either a new better theory, or something that totally disproves the Big Bang theory. We're not going to sit around and try to defend an undefendable theory just because we like it. On the other hand, the only proof or evidence that backs up your theory is the bible, a book that is thousands of years old and has been translated dozens of time (often to better suit the translators goals). When taken literally, it's obvious that the bible is incorrect about a great many things, and there are hundreds of different ways to interpet the meaning (as witnessed by the number of different Christian sects). Finally, there is no outside evidence or proof that even remotely supports the bible. It's all self-contained inside the bible itself. That would be like me writing "Don't worry, all the following answers are correct so there is no need to grade this exam, just give me an A" on one of my exams. I doubt the professor is going to believe me.

The religious bias depends on BOTH never accepting new information and never changing the ideas themselves. It is the ultimate dogma. Of course if you look at the history of religion, all religions DO evolve because there are very few people who'se religious bias is absolute. The Catholic church DID eventually pardon Galileo (he'd been dead for a couple hundred years, but its the thought that counts, right?) because despite their religious bias, they couldn't completely ignore reality. Maintaining the dogma in the face of irrefutable contradictory evidence only serves to destroy the religion. |

The books have the author's NAMES on them. At the very least you must concede that the books were written on paper first by humans (unless of course you believe God is trying to decieve us). So then does God use a pseudonym (again, implying he is trying to decieve us) or did he directly dictate the words to the people who wrote them? If so, why does the gosphel contain 4 different (though similar) accounts of the same events? Did God have trouble making up his mind? Did he redraft and forget to delete the earlier versions? Christian, your point of view here simply does not make SENSE. |

I need to correct Jim, if I understand him correctly. The moon is losing its momentum to tidal friction as it drifts away from us. This loss of momentum is what causes the drift. (The BA's tides page might explain this, I'm too busy to check right now.) The moon is equilibriating the current energy due to momentum with the potential energy due to the earth's gravity. This balance between momentum and attraction is what keeps it in a stable orbit. This, Christian, is also why the moon is drifting away from us even though it is gravitationally attracted to the earth. |

What do you define as sudden? The decrease from the initial temperature to 3000K at decoupling was over the entire 300,000 years, not a matter of seconds or some such small timescale. As I said earlier, the temp of the universe decreases as it expands, and it was expanding the entire time before decoupling. A sudden decrease might be unrealistic, but that is hardly the case. On a quick side note, I believe you are misusing recombination as the 3000K separation of matter from energy, which is decoupling. Recombination is when atoms de-ionized, IIRC. As for your gravitation argument, nature does not abhor a vacuum. The initial pull on the expansion to slow it would still be in effect now, it's just not a constant force. The gravitation attraction does decrease with time, and this slows the deceleration of the initial expansion (assuming no cosmological constant). The Big Bang is also not a constant force, so (with no cc, again) there is no force still actively pushing us now to increase expansion rate. Again, this expansion that is currently happening is uniform in space, not at a uniform rate over time. Quote:
