I read about Tachyons and Gravitational Waves and also about Exotic matter, really nothing can escape a Black Hole, can Axions escape for providing a new hope?

    $\begingroup$ No. Axions are like neutrinos, but yet more smaller. They are not even massless, like photons. Btw, there is no proof that they would exist. $\endgroup$ – peterh - Reinstate Monica Aug 22 at 20:11

Once you are inside a black hole, every direction leads towards the singularity. So for every particle, whether it is massless or not, would travel towards the singularity, and not escape.

Axions have not been proved to exist, but they would also not be able to escape.

  • $\begingroup$ Ok, so an object with 0 Gravity and positive Gravity can't escape a Black Hole but is there any probability that Exotic Matter can escape because it has repulsive Gravity and opposing properties. $\endgroup$ – Loop Quantum Gravity Aug 23 at 7:34
  • $\begingroup$ see physics.stackexchange.com/questions/153376/… The negative mass can't escape, the black hole. $\endgroup$ – James K Aug 23 at 7:42

  • $\begingroup$ James, do you know of any astrophysical entity which can escape the Black Hole. Or, there is nothing in our knowledge, that can escape the Black Hole. $\endgroup$ – Loop Quantum Gravity Aug 24 at 8:32
  • $\begingroup$ To our best current understanding of black holes (GR) nothing can escape a black hole. Space inside a black hole is curved so all directions head towards the singularity, so it doesn't matter what direction you go, at what speed and with what special properties a particle might have, you will always move towards the singularity. It is like "can you escape next wednesday?" because the only permitted direction in time heads towards next wednesday. It doesn't matter what happens you are sure to get to next wednesday eventually. $\endgroup$ – James K Aug 24 at 12:54
