re: Is Titan Alive?
Interesting speculation. Appears to make sense from a thermodynamic perspective, but no evaluation from the biochemical side. The fact that our biochemistry would not work as is under these conditions is lightly addressed by evolution. Possible, but highly speculative given that we don't know what conditions are necessary for life to start. Still seems a lot more grounded in reality than his speculations about current life on Venus. DG is the kind of scientist that breaks barriers by taking a hard look at conventional scientific thought in a scientific manner.
