>>13177891>>13177592When the Spherically symmetric solution for the Enstein field equations, the Schwarzchild metric, was formulated two singularities were present in the field: one at the event horizon, one at the origin.
So these singularities needed to be removed. The Kretchman invariant proved that the event horizon was a coordinate singularity while the origin singularity was physical.
Physicists jumped the gun here.
They said, decades before a black hole was discovered that because the event horizon was only a coordinate singularity that particles could cross the coordinates and afterwards collapse into the physical singularity.
This was a foregone conclusion because it ignores how particles work. (Massive) Particles must travel through spacetime in timelike space. No timelike space, no particles. Timelike space exists within lightlike space, almost always depicted as light cones. In gravitational fields, these light cones must move along the curved spacetime in geodesics. For light, these are called null geodesics. Geodesics are coordinate independent. Regardless of what coordinate system you choose the geodesics stay the same.
To remove the singularity of the event horizon and enter the black hole, physicists have been applying coordinate transformations. This may remove the coordinate singularity but it DOES NOT change geodesics.
The null geodesics of a black hole converge at the event horizon. They converge so completely that there is NO TIMELIKE SPACE on the event horizon. Thus, there are o particles on the event horizon, thus no particles can pass the horizon, thus there are no particles under the event horizon.
All of this bcause coordinate transformations do not transform geodesics which is a mathematical concept so fundamental that I'd expect a grad student to know it but current theory stands ther in defiance.
