We are carbon based. No heavy elements, no carbon, no carbon based lifeforms. That's science, not an assumption. Silicon based life has recently been found.
Got a link? I'd love to read up on that. Is there an analogue in silicon based life forms to DNA?
The parameters of what physics will and will not support life are not fully known as should be obvious from the continual discovery of new parameters and that only this one planet.
Yes, I already stated quite clearly that our knowledge of the universe is quite limited. No argument there.
The idea that we have examined any place other than this planet with any degree of depth or breadth is ludicrous.
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?
An inability to recognize one’s limitations is indicative of an inability to reason clearly.
You reasoned earlier that there was life extant in places other than this universe. Presumably you don't recognize your limitations.
What constitutes “life” hasn’t even been reasonably well defined by science.
It's in flux but we do know that all life is cellular and has other properties that are well defined. That is unless your silicon life forms are not cellular.
Reasonable scientists readily admit that.
Reasonable scientists agree that life has certain properties but that those properties do not exclude other properties or limit life forms to those properties. Our carbon based cellular life forms are pretty well defined which of course does not exclude other life forms or other universes or God.
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 ...
