Does string theory excite you? Mathematically, it holds up. Aspects about it suggest not one but several different dimensions, ones we’re not generally privy to, though we may be interacting with some of them all the time, completely unaware. Were it true, what would these dimensions look like and how might they affect us? And what is a dimension anyway? Two dimensions is just a point. We may remember the coordinate plane from math class with the x and y-axes. Then there’s the third dimension, depth (the z-axis). Another way to look at it is latitude, longitude, and altitude, which can locate any object on Earth. These are followed by the fourth dimension, space-time. Everything has to occur somewhere and at a certain time. After that, things get weird. Superstring theory, one of the leading theories today to explain the nature of our universe, contends that there are 10 dimensions. That’s nine of space and one of time. Throughout the 20th century, physicists erected a standard model of physics. It explains pretty well how subatomic particles behave, along with the forces of the universe, such as electromagnetism, the stronger and weaker nuclear forces, and gravity. But that last one standard physics can’t account for. Even so, this model has allowed us the startling ability to peer back to the moments just after the Big Bang took place. Before that, scientists believe that everything was condensed into a single point of infinite density and temperature, known as the singularity, which exploded, forming everything in the observable universe today. But the problem is, we can’t peer back beyond that point. That’s where string theory comes in. The innovations it provides can account for gravity and help explain what existed before the Big Bang.
