Jack,
mozda bi trebali otvoriti jedan forum posebno za tebe. Ti si bas vredan.
Jos uvek citam
Sta citas ? Koji je tekst Jack postavio? Ne mogu da ga nadjem. Sto se tice zivotnih oblika zasnovanih na silicijumu, jedna veoma zanimljiva ideja je organizam na bazi silicujuma koji prozima cijelu planetu tj predstavlja okean na toj planeti, on je svjestan svog postojanja ali nema teznje za tehnoloskim napretkom vec se samo razvija u drugim pravcima zanimljiva je ideja iz zvezdanih staza tj iz deep space 9, osnivaci siliciumski organizmi koji se ne hrane i mogu menjati oblik.
''SILICIUM BASED LIFE:
Well the Silicium atom has - like Carbon - 4 possibilities to bind with other atoms, thus (theoretical) ability to form long chains, and cycles... However the CHON (Carbon Hydrogen Oxygen Nitrogen) based life is much much more probable:
First C, H, O and N are very frequent elements in the universe, while the next line of the Mendeleiev table is much less frequent.
Second The electronic orbitals around Si are such that it favours ionic-type links, which means: less flexibility, cristalline structure, too strong links. Good example is CO2, very important element in life, a gas at normal temperature and pressure, bringing greenhouse effect capabilities (yes it can help...), while SiO2 is a cristal (harder to incorporate in oxydizing/reducing type of chemical reactions)
Third you need a solvent: the CHON solvent is H2O, water - liquid between 0°C and 100°C... While it would be NH3 - liquid at much lower temperatures... which means the cinetics of chemical reactions are much much slower...''
Ipak, mislim da postoji mogucnost postojanja inteligentnih kristala. Recimo, na Plutonu....
