Turns out in five dimensions you can have that thing rotate in a way that cancels out the gravitational attraction and those two forces for kind of technical reasons balance each other out and are stable.
In this case, I said four space-time dimensions,
important that there is a time dimension.
So four space-time dimensions is one time in three space.
Five space-time dimensions is one time in four space.
not well thought of by most
turn out that in theories with more than one time dimension, you naturally get tachyons as part of the
particles, which indicate a tachyon is not the...
Common thing is it's a faster than light particle.
Really what it means is that you have an unstable theory.
The particles with what we'd say in physics is negative mass squared.
So it indicates that there's some fundamental problem with the vacuum state of your theory.
So if you have, because it's a lower energy state, if they have negative mass squared, then you can start producing tachyons and go to a lower energy state, right?
And that's bad.
Physics always wants to go to a lower energy state.
I
here.
If you have a theory with tachyons, something went wrong.
You misunderstood something.
It's like
