Aliens found?

That's a good question, you'd think they'd burn up in the atmostphere if they were entering it from outerspace.

Yep. That's right! Even small (about 1-2 meters) meteorits burn entering into our atmoshpere and such small cells survive??(I remember this from lessons of geography). Maybe they've came in some flying saucer??

Let me play Devil's Advocate here, but the reason things burn up entering our atmosphere is the speed at which they enter. Early physics, velocity, and resistance cause friction, friction causes heat...With a relatively low rate of descent, they wouldn't catch on fire. Ever seen a sky diver?

But see that's just it, they don't look or behave like blood cells, for one thing there's no DNA, for another they reproduce at up to 600 degrees Farenheit, the hottest any known cell will replicate at (or rather survive at) is 250 degrees. Also red blood cells don't replicate themselves, they are produced by bone marrow, and tend to die pretty quickly outside of the body.

Frankly I don't know what it is, but it's pretty cool, and an interesting topic of discussion.

It's also worth considering that these are hypothesised alien cells, whichmay or may not even play by our known rules... ie. DNA. And I believe that the reproduction temperatures in air are higher than those in water... So when coming through the atmosphere higher temperatures could be survived and reproduced within. And that point about physics is quite valid, especially if the Meteorite broke up high in our atmosphere the frictional force would be minute if you assume a low entrance velocity, and the cells encountered high flying water vapour clouds.

But you've got to think how cool would it be to work on it though???
