Not if you have to push it both ways...The point is that you don't.
Catalytic cycles with multiple elementary steps don't have to work equally well in both directions.Yes they do.
Why did life only generate once?[ What evidence do you have for this assertion? Life as we know it probably evolved on Mars, the conditions elsewhere in the solar system seem favourable, and there are at least 40 000 000 000 000 000 000 000 potentially observable solar systems that we haven't begun to explore. Beware of the Kruger-Dunning syndrome.
We don't see new life crawling around the tidal pools.Possibly the best place for it to evolve, but (a) there's lots of competition in a tide pool and (b) there's something like 8 000 miles of coastline to explore in the UK alone. The chances of anyone finding a new bug and proving that it had no organic ancestors are pretty small - we haven't catalogued all the "known" species yet.
Why does life have only one manner of replication? Is DNA the only answer?I think the answer lies in the question. If you define life as being the effect of replicating DNA, there cannot be another.
Because it is a metal, it is both excellent at emitting radiation,Erm, actually, no. Shiny things are poor at radiating heat.
I have seen pictures of industrial plant where they store molten Iron in special insulated containers and transport it to a different part of the plant by rail.The biggest factor in their favour is that they do it on a big scale.
Keeping "lava" molten for long periods will require either amazing insulation, or a lot of energy.
Is a cloud gaseous water or condensed water?yes
The boundary of the cloud is not a true edge: water is going in and out of the cloud all the time. But only within the region of the cloud is the aerosol stable. Any water outside of the cloud is either in the gaseous state, or is precipitations (solid or liquid).
This is a pretty dense gas - how well would it mix into the stratosphere?
