Ok, so a quick question for anyone who'd like to throw in an answer.

Is the Riemann Hypothesis true? Please, no references to 'proofs' that
haven't made it into respected journals yet...

I'm asking for opinion, rather that proof. Who thinks it's true? Who
thinks it isn't? Who thinks it don't matter too much?

This is only a little fun, of course...

Yes, it's true. But I'll keep my proof to myself for now, hehe.
Actually, I know it has to do with the observation that solutions to
the Zeta function in the complex plane are either trivially on a line
or else symmetric around a line, but that's about all I know. It's
beyond me.... But I figure that nature should be symmetric...

What do you mean 'trivial'?

I still don't get you. But I presume you're trying to say that zeros off
the critical line have a much larger effect than those on the line. But
of course it would depend on how many such zeros there were, hence the
idea of zero-density results. I presume that's what you mean?

Leaning tower?

Hmm ok, I guess that's one way of looking at it. But like I said, it all
depends on estimating how many non-critical zeros there are. As long as
there aren't too many, the tower wouldn't budge.

Depends what kind of prime information you're looking for really. You're
right in the sense that the strength of the error term in the PNT is
equivalent to the size of the known zero free region for the zeta
function. So just one zero really can upset the PNT. But I don't see
why one zero can affect all the others though.

Yes, a non-critical zero makes a larger contribution. It's not
necessarily the end of the world though, it all depends what you're
trying to prove.
