We don't really know this. It's possible that singularities are physical. A lot of physicists suspect that a theory of quantum gravity would show that classical singularities really stop blowing up when you get to the Planck scale. However, we don't know that, because we don't have a theory of quantum gravity.elusiveshame said:Singularities aren't physical, they're just where the physics stop making sense due to a lack of knowledge.
No. Black hole singularities are inside an event horizon, so you can't observe them from the outside using a telescope. You may be thinking of attempts to image the event horizon.elusiveshame said:I read somewhere that we'll hopefully be able to peer further into black holes with one of the telescopes being constructed now. I'll try to find the article when I'm on a computer.
Even "a little bit inside" is problematic. More likely, we will develop a theory of quantum gravity whose predictions match observations everywhere that we can observe (as does GR) but also predicts something more plausible than a singularity at the center of a black hole.elusiveshame said:I should've make my "peeking in" a bit more specific: I didn't mean we would observe the singularity, but rather we would be able to peer a little bit inside of a BH, not so much observing the inner workings/singularity.
To amplify on what Nugatory said, you might want to look up the definition of an event horizon and think about it carefully. Simply as a matter of definition, you can't peek even a little inside an event horizon. (You could hypothesize that event horizons don't actually exist, or that GR describes them incorrectly, but that would be a different issue.)elusiveshame said:I should've make my "peeking in" a bit more specific: I didn't mean we would observe the singularity, but rather we would be able to peer a little bit inside of a BH, not so much observing the inner workings/singularity.
