Yes, a simple drawing in my post Gravity...... illustrated the point. And orthogonal within a black hole is why the star shrinks but does not point to a singularity (as most assume). As time near the star (at the bottom of the 'well' ) does not point in the direction of time exterior to the black hole (as with non-blackhole stars) the star becomes detached from our universe.

In normal Gravity situations, time is orthogonally pointing inward and this together with time at the base of the well (again orthogonal) pointing in the direction of 'normal' time then the well shape is maintained as time progresses. In the case of a black hole the basin shape becomes a tunnel and the star is left behind in time. It detaches maybe. Perhaps at this point time (as maybe aeons pass outside - or not) is recovered but pointing outward as per our universe (but produces a new universe).

All this speculation arises from the principle that time is orthogonal to space (nothing controversial there!)

I also think that the star of the black hole is on the other side of the tunnel, and not as mainstream science says, that there is a singularity in the horizontal direction, because space follows the tunnel. But the star is stuck there, there is no link to another universe. It's only a small pocket where time locally passes in reverse.

Coming back to the question, mainreal physics claims that space curves in a virtual 5th dimension w. But in the Painlevé coordinates we see that space curves in local time, which then corresponds precisely to the dimension w, and as this is reality, the other coordinate systems are only geometric deformations. However, as time is a scalar of density and not the vector that Minkowski speaks of, we have the three dimensions of spaces curved using density.

Mainstream science does not understand geometry correctly, it makes crude figures, like this:

en.wikipedia.org

On the horizon (at 2), the world line of the free-falling object is tilted at 45° and not 90° because the diagram does not reproduce the tilt of the local time axis. Normally the faller's worldline is the local time axis, but in this diagram the local time axis is represented vertically and is the ordinate. So they do not see that space is sloping and that the horizon cannot be crossed horizontally, they pretend that the faller crosses the horizon as shown on the diagram and that the world line becomes horizontal on the singularity only . It looks like they're doing it on purpose, because the math equation clearly states that the time axis should tilt. They simply do not represent the geometry indicated by the equation.
