*Disclaimer: I do not claim to be knowledgeable quantum mechanics past amateurism. I'm just interested in the topic.* I had a thought during Classical Mechanics Physics class two days ago on the nature of singularities in black holes. I realized-at least in my speculation-that singularities could not form in real space-time due to the Casimir Effect. If I am understanding it correctly, quantum mechanics states that a particle's energy is inversely proportional to its wavelength; ergo, the smaller the space, the more energetic the particle. I am making the following assumptions about black holes: normal quantum mechanics apply inside it-that virtual particles form inside its space-time. As the space of the singularity approaches zero, shouldn't the energy of the virtual particles become infinite (or at least on the level of the Planck energy). As there is less and less space, the Casimir effect should start gaining significant strength, and a strong negative pressure should result, blowing the singularity apart again. I guess I subscribe to the fecund universe theory with this hypothesis. So, without speculating on the mathematics, I am proposing that black holes do not have singularities, or at least not for any meaningful time. It is possible the Big Bang's singularity formed due to a virtual particle interaction inside a black hole blowing apart the singularity, in my opinion. Thoughts? If this is already a theory somewhere, I take no credit for it (I tried looking, but I couldn't find it). And if I'm wrong, feel free to correct it.
