A hole in the black hole
[microresearch]
Supposedly, matter falls inside the black hole whenever it reaches its event horizon. The Planck scale, however, imposes a limit on how much matter can occupy the center of a black hole. It is shown here that the density of matter exceeds Planck density in the singularity, and as a result, spacetime tears apart. After the black hole is formed, matter flows from its center to its border due to a topological force; namely, the increase on the tear of spacetime due to its limit, until it reaches back to the event horizon, generating the firewall phenomenon. We conclude that there is no spacetime inside black holes. We propose a solution to the black hole information paradox.

Dark matter and bubbles of void
[original insight]
This is a thought experiment with the following conjecture: bubbles of spacetime void alter the gravitational field of the galaxy and might explain the dark matter phenomenon.

Route one to quantum gravity
[original idea]
These are the first steps, I believe, that can contribute to the understanding of the most fundamental nature of spacetime.

The interior of a black hole and the void of spacetime
[original idea]
This article connects the following concepts: the “interior of a black hole” with the “void of spacetime,” by means of a thought experiment.
