cookie121 Posted July 25, 2010 Report Posted July 25, 2010 At the moment of the Big Bang before everything that exists as we know it, what/where was this ultra dense energy source suspended and what if any physics existed before this moment bearing in mind that nothing existed before the Big Bang!!

garc Posted July 25, 2010 Report Posted July 25, 2010 ...and God said let there be light... ...maybe it was a fart... Love these programmes. It's great how putting fancy graphics onto 'some made up shit' can make people believe that it's a fact. Quote

gjpo1 Posted July 25, 2010 Report Posted July 25, 2010 OOOOOOOO! Pretty! Bit like a thought, idea, concept about anything really, only on a bigger scale. Where do they come from? What do they look like? How do they develop? What determines the result? Personally, the end of 'Men In Black' tickles me, who's to say that's not how it is. Especially if thought really can become form, which man proves on a daily basis. How's that? Quote

The Geoff Posted July 26, 2010 Report Posted July 26, 2010 Multiverse theory is my "thing" - it's one of the ways of explaining why our universe is set up like it is. Imagine the universe has a control panel...it consists of twenty-something dials, each of which sets a physical constant like the universal gravitational constant, or the charge on an electron. They all have a full range of values which could possibly make sense. Tweak any one of those dials and you'll probably break the universe as we know it...atoms won't form, stars won't burn, protons become unstable...there's a lot of ways to break the universe and very, very few settings that will lead to any kind of complexity let alone life. Long story short, the universe seems to be exquisitely and very carefully designed to allow complex life to develop. Science doesn't like this, because it's difficult to explain. Yes, you can invoke a creator, but it might as well be a flying spaghetti monster as anything else, and it's not really science because it doesn't suggest any experiments that could prove the idea wrong. Science doesn't say there isn't a god, just that god isn't a valid scientific theory. If, however, there are a bunch of universes with all possible settings, then there has to be one like ours, and we can only exist in one like ours, so we do. QED. It's like saying that it's weird that out of all the planets in the universe, with all possible temperatures and gravities and so on, that we evolved on one with liquid water and 1g of gravity. Ironically, this isn't science either. Yet. There's a bunch of scientists talking about the ideas and trying to work out if it might ever count as a valid theory...currently there are at least four different "levels" of multiverse which include various parts of quantum theory, string theory, philosophy and cosmology. My preferred theory is that the universe is basically a quantum computer which is working out all possible configurations of all possible universes, and that gravity is not a fundamental force but is processor lag holding matter back slightly in the time dimension....but it's probably wrong. Some would say it's not even wrong..... Quote

Some would say it's not even wrong..... Possibly a quantum computer that we invent in our future and it turns out that we actually started it all in the first place !! Funny how we always seem to get to a point where we think we have THE answer but it just slightly shifts as we try to grasp it and it becomes something else. The universal bar of soap !! Quote
LeonR Posted July 26, 2010 Report Posted July 26, 2010 This could be a rather intense thread Remember, physics is based on what we know, and who knows what else there is to know Quote
danmon81 Posted July 28, 2010 Report Posted July 28, 2010 Sounds very Douglas Adams to me!!!! :-) Quote

tszy Posted August 24, 2010 Report Posted August 24, 2010 "If, however, there are a bunch of universes with all possible settings, then there has to be one like ours, and we can only exist in one like ours, so we do. QED. It's like saying that it's weird that out of all the planets in the universe, with all possible temperatures and gravities and so on, that we evolved on one with liquid water and 1g of gravity" This is I believe, the basis of the anthropic principle. The term '1g of gravity' is meaningless, - if the Earth was twice as massive as it is, what we refer to as 1g would actually be 2g - better to quote the acceleration due to gravity or the mass of the attracting body in multiples of the Earth's mass Quote
The Geoff Posted August 24, 2010 Report Posted August 24, 2010 Or, to take it a step further, 1g=9.81m/s/s, and both metres and seconds are arbitrary units based on the Earth's size and orbit. You've got to measure it somehow though, furlongs per fortnight per month is my personal favourite. (1.5511912 × 10^11 since you ask) Quote
