comment What methods can astronomers use to find a black hole?
Hawking radiation is inversely proportional to the black hole mass, so I don't really hold my breath for having a detector able to see Hawking radiation from ordinary black holes.

comment What are the most fundamental assumptions of quantum mechanics?
as a quantum chemist would say, yes, it exists, but its projection in the english space has lower dimension, thus has a larger error due to the variational theorem.

comment What are the most fundamental assumptions of quantum mechanics?
@mumtaz:The electron is technically handled as a dimensionless point, but it's irrelevant. What you work on is the coordinate of an electron, but what you have is a coordinate of space where an electron's wavefunction has a given value. when you say wavefunction $\psi(x)$, your $x$ is a dimensionless point, but it's not really like you have a infinitesimal particle stuck in point $x$.

This is hardly in plain english ;)

comment What are the most fundamental assumptions of quantum mechanics?
I would not say "probabilistic existence". It's not like if you say "the electron has, say, 40% probability of being here" does not mean that it spends its time 40% here and 60% somewhere else. I think the plucked string is the most appropriate real-world example. It's not like in the middle of the string there's all the vibration 40 % of the time, and 60% is somewhere else. The vibration is just 40 % there and 60 % on the rest of the string.
