Things you don't need to know...

Posting this one here in stead of the daily smile thread due to its veeery geeky nature:

It's true. Archaea, one of the three domains of life (the other two are bacteria and eucaryotes), is not known to cause disease on humans.

PS.
Many species in this domain are extremophiles, and some of them have very weird shapes, like Haloquadratum walsbyi (an extremophile who likes waters 5 times more salty than sea water) whose cells are squares.

And BTW, archaea, not bacteria, is also the domain that probably gave rise to the eucaryotes and eventually us.

Good to know but it won't matter in a few billion years the whole universe will go dark, and then bam another big bang will happen. Wish I could live long enough to experience space travel, though I doubt it'll happen in 50 years from now.

Actually it will take trillion of years before it turns black. Red dwarfs which dominate galaxies live for a veeeeeery long time. Practical consequences limited

Pibbur who thinks (guesses, hopes) we'll see another Big Bang, but the jury is still out.

Sorry meant trillions but makes you wonder, if so how many times has it happened?

Interesting fact, I thought that all cells tend to be spheres in one form or another. This looks like an early version of the windows-logo, btw ;)

Actually this is an open debate as to whether the universe will eventually collapse or expand forever. However lets pose this thought if it does collpase to re-explode will everything that previously happen repeat itself and will we relive these moments at some point in the distant future ?
