If there was a higher 5th dimension and the universe we observe is a 4 dimensional slice of this, could all point particles have size in 5 dimensions but only intersect our universe at a tangent or 0 dimensional point. Like a circle touches a line without intersection.

 

Could heisenbergs uncertainty principle be the result of vibrational movement or KE in the 5th dimension?

 

Does it make sense to view a singularity as a zero point particle. Where all its mass in 5d no longer intersects the 4D universe but touches it at a single point.

 

Could 0 point energy, or virtual particles be random intersection, due to the uncertainty principle of 4d space and 5d space. IE the line very close to tangent (our 4 dimensions) vibrates briefly to intersect with the circle (5d) protrudes into observable space time and then warps back again to where it doesn't intersect?

 

So could virtual particles be seen as dynamic random vibrational intersections of 5 dimension with 4 dimensions?

 

Hawking radiation could be seen as the circle edge or line forming a wave across the boundary and protruding through 4d. Where one half of the 5d wave function intersects 4d and the balancing other half remains unobservable in 5d.

Something like a string propagating in 1+4d? Single free strings are sick in such dimensions, but maybe not interacting ones. People do think about non-critical strings. Maybe that is something close to your ideas.

Your idea has all the appeal of string theory without the ;'elegant' math.

Oh wait...

That is the only appeal of string theory !

( I joke )

Most of the string theories I've read about have dimensions "below" ours, curled up tight. I never got that analogy.

These extra dimensions in these models are 'compact and small'. This means that at low energy they do not appear as extra dimensions buy manifest themselves as 'internal degrees of freedom'. This is one way of understanding why we do not see these extra dimensions directly. You should look up the old KK theory for the general idea.
