You make the assumption that all life has to be carbon based. I already told you that silicon based life has been found on this little planet.
Is there an analogue in silicon based life forms to DNA?
What difference would that make?
Yes, I already stated quite clearly that our knowledge of the universe is quite limited. No argument there.
Then you should have no trouble seeing that Townes theory is based on one huge assumption.
LOL, that doesn't stop the multiverse folks from using the multiverse to declare all things can and will happen. But I'm not making that argument so, so what?
I'm not making it either that's so what. Townes uses it as a counter-point to set his theory on. If it's a shaky point it's an even shakier counter-point.
You reasoned earlier that there was life extant in places other than this universe. Presumably you don't recognize your limitations.
No I didn't. Not once.
It's in flux but we do know that all life is cellular and has other properties that are well defined.
Defined by observations too limited to reasonably extrapolate to the entire universe and all its potential environments.
Reasonable scientists agree that life has certain known properties ...
Yup, so you did. Now I'm waiting for the link.
But silicon is a heavy element similar to carbon. No heavy elements, no carbon based or silicon based life. Now it could be a coincidence that teh anthropic principle is tuned for heavy elements and carbon/silicon based life. It could also be that there is in fact a multiverse which assures that every possible outcome is met. It is also possible that God did it.
But none of that has ny bearing on our discussion or what Townes thinks or doesn't think. Our discussion is between you and I and you are wrong when you claim that it isn't science when a scientist demonstrated that small cahnges in the physics of the universe prevents heavy elemnets in abundance and thus precludes carbon/silicon based life. That is indeed good science. In contrast, the multiverse and God are metaphysical.
