It turns out that Thomas Gold was right about the deep hot biosphere:

So, if we humans sterilize the planet's surface, eventually more life might migrate up from below to build another biosphere on the surface.

I was expecting another Trump thread.
The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails.

Huh.  I've never thought about that.  Plus, on planets that might've had life on the surface in the distant past but the surface has since become inhospitable for life as we know it (Venus, Mars), native life might be doing just fine underneath the surface, just waiting to be discovered.  Quite a hopeful idea!

Early life didn't like oxygen.  Once the atmosphere went with oxygen, it had to burrow underground.  Bring on the Mole People!

I doubt that Venus has any sort of deep hot biosphere, since You are not allowed to view links. Register or Login, completely resurfacing the planet.

There's still plenty of hope for Mars, though!

It's possible, so what?  They wouldn't be likely to produce any complex life before the Earth was destroyed by the dying sun.

Well, they might. Too bad we'll never be able to know.

You are saying then that Venusian life developed faster (if it ever existed) than Earthian life?  It possible, the planet is hotter.  Just asking why you thought it...

Geological processes near and on Earth's surface should, over time, bring micro-organisms up from below the surface, which will begin creating new environmental niches to inhabit and exploit. Eventually that might again lead to multicellular life forms that would again evolve to create a new surface biosphere.

I don't know what that has to do with Venus.

Venus - depends on the particular thermal and acidic history of the surface.  Was it always so hot and acidic?

It is unclear, that as cellular life forms evolve, that in the long run, they are permanently cutting off certain adaptations (aka entropy bites).  In which case a extremophile might be so highly adapted, that it will never have any mutate offspring that can tolerate a normal surface condition.

No offence meant.  It just seemed to be a logical extension of your earlier post...

No offense taken! :-)


It isn't clear whether the deep hot biosphere would have sufficient time to evolve a new intelligent species before the sun heats up too much to allow surface life. The sun may last another five billion years or so, but Earth will become uninhabitable long before that, maybe only one or two billion years. But that may be enough time, I don't know.

If me can't find a way to live elsewhere in the next thousand years, we probably don't deserve to continue.  Ever read 'Breed To Come', or 'The Uplift Wars", BTW?

No. I've heard of the latter, but not the former, and haven't read either. I'll see if the library has them and give them a look.
