Sense the 1920s the commonly excepted scientific theory for the creation of the universe has been the Big Bang Theory. A theory for which a singularity of infinite mass exploded to release the cosmos we know today. I was recently poking around on sciencenews.org when I found an article about a whole different theory that connects the big bang theory with string theory to offers a new theory of how the big bang happened, why scientists think it will happen many more times in the future, and why there could be different universes each with different properties.
In 1981 a scientist names Alan Guth proposed the idea that the universe underwent a short period of faster than light expansion known as inflation. Scientists now think that this period of inflation could have happened many times before and will happen many more times in the future, each time sprouting a new bubble of universes. These universes could have completely different states of matter, different laws of physics, and even different state s of time. But the question is, why?
In a new model produced Dr. Steinhardt at Stanford University the multitudes of universes could be attributed to the constant expansion and contraction of three-dimensional sheets of space know as branes, minute distances away from each other which travel along an extra dimension of space. When they are separated the branes are wrinkle free which represents a universe that is completely devoid of matter or a time when the universe has expanded to the point where matter is so spread out that it barely exists. When the branes are close together they develop wrinkles that represent seeds of galaxies and other massive cosmological masses, this would represent time when the universe has a massive amount of condensed matter. When the branes finally collide they release a massive amount of energy and trigger the emergence of a new universe and the cycle of the branes slowly moving apart repeats’. To an observer, this collision would be a “big bang” or a “big bounce.” In this model there are unlimited universes that have been created or have yet to be created and all universes have an effect on each other due to the wrinkles left of the branes of space. The only way scientist know to test this theory is to continue the search for massive gravity waves that have left their mark on the very fabric of space time with each “big bounce.” The European Space Agency’s Planck spacecraft is on it way to look for these massive waves effect on the cosmic background radiation, although scientists predict that the waves to could be so spread apart it could take a millennia to even start to recognize patterns in the radiation, they have to start somewhere.
