Earth-Like Planet Discovered!

...what is all this talk of 'mantles'? What is a mantle in this context?

http://en.wikipedia.org/wiki/Mantle_%28geology%29

it was in Horizon last june "life on mars" it was about looking for life in more uncoventional places hence talk about bactirum in the earths, no links, its documentary series

I see...I'll poke around and see if I can find any information on this elsewhere...if it was on a documentary series there should be information on the internet.

there is life in our upper mantle discovered a few years ago showing that light is not needed for life

A source please. Not that I doubt you so much as I would like to see some evidence for this, as it would be quite exciting.

That's easy: Ocean floor.

Nonono. Life in an ocean floor vent is completely different from being able to live in the mantle itself. The life at the vent only live around it, not inside of it. We're talking a serious difference in terms of pressure and sheer temperature.

Your tell me that an are in which no natural light source can reach  is completely invalid? The ocean floor during the middle of the day is as pitch black as the desert outside Las Vegas. It thrives by other means, and contains a whole ecosystem further secluded then that of the higher elevations, some of which cannot rise up for risk of actually dying to decompression.

Learn to fucking read.

The point of contention isn't the fact that there's life living off of the Earth's radiant heat on the ocean floor, but that your example has nothing to do with living "in the Earth's mantle."

Unless, of course, you think the ocean floor is a sea of molten rock, in which case you're a fucking idiot.

Good god. Symmes hole. =]

I can't imagine the desert outside Las Vegas to be that dark.
