2. Now....hmmm...all this time I thought Time was money. That is what I was told by an entrepreneur. Then , one day I was told by a southern preacher/evangelist that Money was the root of all evil. So, I applied that knowledge to kill time, for that would eliminate evil. However, evil has grown instead , and time has marched on, and here I sit posting on a forum killing time and wasting money.

4. I've come over all cranky, possibly due to reading the posts above, whatever: There appear to be at least three spacial dimensions in spacetime but on the face of it only one of time. I have never considered before the possibility of a spacetime comprising more than one dimension of time. I'm not even sure what this means.

This thought process was prompted by an early post stating that time was what separated events or prevented everything happening at once. Well, if you look at time at right angles to the time line then everything does happen all at once....

So, forgive me, I'm enjoying this, One could have 3D2T or maybe even one or more 'compacted' or 'rolled up' time dimensions etc etc blah blah.

I guess my question is ( as I am not a mathematician) is there anything in the maths of spacetime/manifolds that actually prevents this bizarre possibility?

That is correct.

Not at all. The mathematics used to describe such space-times is called "differential geometry", and it has no problems describing manifolds with more than one time dimension. The problem is the physics, specificially the question of whether such a universe would be stable and able to support life. Have a look here :

6. Thanks! A really excellent piece, well written and clear. My questions.. Answered. I have book marked it for future reference.
