Science Vs Christians

So we have a question in the comment section, and I quote, " I'm inclined to think space existed out of necessity. The absence of space doesn't make sense. Why is there something rather than nothing? Because nothing isn't possible, I suspect. Space is required not created, I think." About a year ago, I had a discussion with a physicist professor when I begin to realize just how hard this subject is to comprehend. The interesting thing about the question proposed in the comments is that it goes hand in hand with the thesis of this debate. Lawrence Krauss theoretical physicist and author of the bestseller "The Physics of Star Trek" wrote a book called "A Universe from Nothing- Why there is something rather than nothing." In this book he comes from an interpretation of the Big Bang that since time and space was born at the moment of the big bang then there should be no outside of space and time. Because time begin at the big bang, there should be no before, and because space begin at the big bang there would be no outside. So what are we left with? Nothing! My position is that because the general theory of relativity breaks down at a singularity: because it cannot handle infinite numbers, then in order to go past the beginning of space and time, we need a more complete theory. We need a theory of everything, that would combine all four fundamental forces, along with general relativity and quantum mechanics. Right now we believe that would be M theory; a theory that combines 5 different versions of string theory into a single model, proposing the existence of 11 dimensions. Now, let's not get ahead of ourselves: because in order to understand string theory, we must step back into the big bang theory. As I explained above, the big bang theory very briefly states, that the universe is expanding, and we have recently found that our universe is expanding at an accelerating rate and much faster than the speed of light. We believe the cause may be dark energy, and is undergoing investigation at this point. In Einstein's general theory of relativity, he proposed that space and time is a continuum in which can be warped or curved by the distribution of mass and energy within it. This idea followed from Sir Isaac Newton's laws of motion and laid out the ground work for Alexander Friedman's model of an inflating universe. On the other hand, Penrose's theorem showed that a star collapsed under it's own gravity would go back to a singularity. Concurrently, using the time reverse argument, we could show that a Friedman like model universe would too. So, if the universe is expanding, then what is it expanding into? Stephen Hawking once made a proposal called the "no boundary proposal" in which can be best understood with a balloon. Imagine, that we took a balloon and we marked several points before blowing it up, then those points would begin to move away from each other, without any of them being able to be said to be the center. It's much like a loaf of raisin bread, as it expands all of these raisins would move away from each other. Here is the problem; those sides do not exist so those points are just expanding and even the atmosphere itself is inside of this balloon. In fact, everything including space and time exist inside of this balloon in four dimensions (3 spatial and 1 temporal). http://www.hawking.org.uk... http://www.pbs.org... M theory, however, proposes the existence of more dimensions. In order to understand what these 11 dimensions are, we need to step back to a paradox of time travel. Firstly, time travel was thought to be the ability to travel in the fourth dimension and rewind the clock back in order to visit people in the past. On the other hand, we could travel in the fourth dimension, fast forward the clock and visit our descendants hundreds of years from now in only a few seconds. Though forward time travel is mathematically supported by general relativity, traveling backwards in time seems to run into a problem- retro causality. http://m.youtube.com... Imagine a scientist opens up an Einstein-Rosen bridge (wormhole), and travels backwards in time to kill his grandparents when they were children, in order to prevent his own birth. Well if he is not born, he cannot travel back in time making the mission seemingly impossible. We have worked out a number of solutions, but one in particular goes back to the many worlds hypothesis in quantum physics. http://plato.stanford.edu... In this many worlds hypothesis, there could be an infinite number of universes, including those that mimic our timeline in it's current state, millions of years earlier, or even a million years from now. In order to travel backwards in time would mean that we would have to step out of our three dimensional membrane, and into one of these parallel universes. However, it is not quite that easy. We could be two dimensional objects stuck on a higher dimensional membrane, completely unaware of parallel universes right next to us. The best answer to why we cannot actually see other universes outside of our own, would be the fact that light travels at 2.99*10^8 meters per second, and in the 13.8 billion year history of the universe, light would not have enough time to actually reach us from outside. So we propose that there could be multiple universes, which would indicate that our universe is not the only one out there but that there could be an outside as well. And since space and time is a continuum, that was created at the moment of the of the big bang, we cannot really say that space can exist outside of a universe. Instead, it could possibly exist within other universe as an ingredient necessary for expansion. Outside of the multiverse, there would be no continuum, and no space, and no time- this, I call infinity. This is where the membranes would exist, with parallel universes. And a collision would cause enough energy to release, and this energy would go into the big bang itself.
