The Man Who Invented the 26th Dimension
StartsWithABang (3485481) writes Based on all the experiments we've ever been able to perform, we're quite certain that our Universe, from the largest scales down to the microscopic, obeys the physical laws of three spatial dimensions (and one time dimension): a four-dimensional spacetime. But that's not the only possibility mathematically. People had experimented with bringing a fifth dimension in to unify General Relativity with Electromagnetism in the past, but that was regarded as a dead-end. Then in the 1970s, an unknown theoretical physicist working on the string model of the strong interactions discovered that by going into the 26th dimension, some incredibly interesting physics emerged, and String Theory was born.
LOL, based on how nobody has ever been able to explain WTF String Theory actually claims to tell us or how you'd verify it ... I'm not sure of his 'sanity'. ;-)
String Theory has always been a little dodgy, and there seems to be about 20 different versions of it, most of which seems to not to make sense, even to many physicists.
Lost at C:>. Found at C.
Not only does a 2nd time dimension allow for actual time travel (in a one dimensional universe you can't change the order of anything - you need a 2nd space dimension to hop over or around someone in front of you - so a second time dimension allows for time travel).
But also it make it a lot easier to understand why we do not SEE the 5th or higher dimension, let alone confirm it with scientific instruments.
I can look up/down, North/South, and East/West, but I can not look past/future. So it makes sense that I also can not look t2+/t2-.

There are less of them now than there were a few years ago, the LHC saw to that. The data they gathered on the Higgs Boson ruled out numerous theories, though there are still a lot more to go.
String theory was devised as a mathematical model that seems to describe a workable universe which may, or may NOT be our universe. Problem is that we know that the Standard Model cannot be the complete picture but so far we have no experimental data to use as a starting point to figure out what lies behind it. When we finally do get a hint of new physics some of the new math being invented by String Theorists is going to be very useful weather or not String Theory itself correctly describes our universe.
