One things for sure- I`m not about to try and find out.

That makes sense from a scientific standpoint.

You could always try boiling the hops (and/or wort) for 6 hours...

I kid, of course, but this is for my edification as a future brewmeister...what is the longest period of time that anyone has boiled, or should boil, the wort, and what damage would occur if this were to be taken to excess?

This can be done. Some Scottish ales have been made in this manner. You can over do it & Caramelise (probably not the correct term) the wort though. Which will darken & sweeten the beer. I also believe that this can also produce Diacetyl.

The longest I've boiled for is 120min with the 1st hop addition at 90min.

I can`t get my head around this

Is this what we`re saying-if you use, say, up to 100g. Green Bullet hops with an 14%AA, you won`t increase the bitterness by using 200g. of the same hop in the same manner.
Apologies for being a dumb bastard, but I can`t figure why.
More equals more to me?

My theory is that you will increase the bitterness but you wont double it.

Am I correct in saying that there simply isn't room in the wort for the additional alpha acids to go into solution/emulsion?

That`s probably a good theory, KIP, but the mathematics of it all escapes me. I just make it and drink it.
Matter of fact........

Hear, hear! Screw the bloody math and have a drink, mate!
