  • [ – ] Professor_creepy reply Funny.... Because your theories on the big bang are still as accurate a anything that Joh guy said. It is literally all still theory. Also, you stated that "The energy could have came from nothing".... I thought you were insulting him for him not understanding science... You don't really have a grasp on science either - do you? Nothing can't create something. That is scientifically impossible. Stick to SJW videos...
    • TheRealHawkeye parent reply I really don't like the way you use the word "theory" in this, because what is thought of as a theory in normal life is not what a theory is in science. What people usually think of as theory is a hypothesis in science. Only when that hypothesis is proven by a bunch of experiments, it becomes a theory. (you probably know this, I'm just commenting for the broader "public" :) ) Granted, a theory is still not written in stone, but anything that replaces it has to be at least as good at explaining what happens as the previous theory. For example, Einstein's Theory of Relativity replaced Newtons Laws. This doesn't mean that Newtons Laws are suddenly all wrong and don't apply anymore. Newton's Laws are perfectly fine in describing how masses move under normal circumstances (good luck trying to ignore Newton's 1st law driving towards a U-turn at 100 miles per hour) Only when those masses move _extremely_ fast,, i.e. a fraction of C, things get to a point where Newton's Laws don't apply an...moreymore. So Einstein's Theory of Relativity didn't invalidate Newton's Laws, but supplanted, extended, improved them. As for the impossibility of energy coming into existence out of no-where, well, at the very beginning, when the universe was younger than the plank time (10^-43 seconds), our known laws of physics didn't apply. From http://astronomy.swin.edu.au/cosmos/P/Planck+Time With its associated Planck length, the Planck time defines the scale at which current physical theories fail. On this scale, the entire geometry of spacetime as predicted by general relativity breaks down. Consequently, on such scales, an as yet undiscovered theory that combines general relativity and quantum mechanics is needed to describe the laws of physics. For this reason, our current descriptions of the early evolution of the Universe start at tp = 5.39 × 10-44 seconds after the Big Bang. And from http://www.physlink.com/education/askexperts/ae281.cfm The Planck time is the time it would take a photon travelling at the speed of light to across a distance equal to the Planck length. This is the �quantum of time�, the smallest measurement of time that has any meaning, and is equal to 10-43 seconds. No smaller division of time has any meaning. With in the framework of the laws of physics as we understand them today, we can say only that the universe came into existence when it already had an age of 10-43 seconds.
