THE MULTI DIMENSIONAL UNIVERSE

The world in which we live has three dimensions of space, the length, width and depth and with another dimension of time. Beyond this, a baffling possibility that many more dimensions exit in the universe. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions. As far as man is concerned, what is recorded in our retinas in only two dimensions. Here comes a question, if there are 10 dimensions, why don't we experience all of them. This is answered by Lisa Grossman at ScienceNews that these dimensions are so tiny and so fleeting that we currently can't detect them. But this can be countered by the fact that, tiny or extra large are merely a state for the time being. It can be varied on either side any time.
The writer explains about the string theory: "It is difficult to completely explain the mathematics behind the string theory without putting on a graduate seminar or two, but in essence dimensions five through ten have to do with possibility and include all possible futures and all possible pasts including realities with a totally different physics than those in our universe.
If two protons smash together at high enough speeds, they have the ability to create a tiny black hole that would exist for just a fraction of a second before disappearing. The collision would open up a little bubble of interdimensional space where the laws of physics are different than ours, leading to an event known as vacuum decay. In quantum physics, vacuum physics implies that if the interdimensional space was large enough, we had be toast. With enough gravity to interact with our world, the newly formed 'Cosmic Death Bubble's would grow at the speed of light, rapidly change the physics of our universe, render it uninhabitable and effectively zap us out of existence.
