Do the 11 dimensions in string theory have scientific names?

How do you know it is space like?

That's the way the physics comes out. Physicists are not going to assume more than one time dimension until they see some real reason to do so. There hasn't been any so far. So all their theories follow the relativistic model: one time dimension and the rest spacelike.

I mean how do you know the physics represent space. Could they be representing something that just has the properties of space?

Doesn't matter if it's "space" or something "just like space". What matters is what the equations say, and they can't tell the difference. You have the same thing in general relativity, with "curved spacetime". Is spacetime a thing? That it can be curved? Or do we just mean that geometry varies from point to point?

Maybe i should refine my question.. What kind of form does this space take and could you compare it to anything in form that can be seen by us.
