Dunenewt Posted October 31, 2002 Share Posted October 31, 2002 What do you mean perhaps its scientific proof Quote Link to comment Share on other sites More sharing options...
Anathema Posted October 31, 2002 Share Posted October 31, 2002 I don't see how life could have begun without sunlight- unless the first lifeforms would take their energy from geothermal energy, like geysers. Quote Link to comment Share on other sites More sharing options...
Acriku Posted October 31, 2002 Share Posted October 31, 2002 The Sun is vital! Without the sun everything will be stonecold (steveaustin) and no life can develop under such circumstances. Maybe very very simple organisms but that's as far as it goes. Quote Link to comment Share on other sites More sharing options...
nemafakei Posted October 31, 2002 Share Posted October 31, 2002 Without the sun, there is no source of energy. No source of energy means no life. Quote Link to comment Share on other sites More sharing options...
Acriku Posted October 31, 2002 Share Posted October 31, 2002 Well bacteria can travel on asteroids frozen, from another more habitable planet, and crash into a planet with no sun to orbit around... Quote Link to comment Share on other sites More sharing options...
Edric O Posted October 31, 2002 Share Posted October 31, 2002 You do realize that the temperature on such a planet would be extremely close to absolute zero, don't you? Quote Link to comment Share on other sites More sharing options...
Acriku Posted October 31, 2002 Share Posted October 31, 2002 Mine? Too bad absolute zero is theoretically impossible :( Or else I could have the coolest planet. Quote Link to comment Share on other sites More sharing options...
nemafakei Posted October 31, 2002 Share Posted October 31, 2002 They can travel frozen, but they can't do anything until they're unfrozen. I reckon 6K (-267 Quote Link to comment Share on other sites More sharing options...
Terror Posted October 31, 2002 Share Posted October 31, 2002 Acriku is right though, Bacteria were found on asteroids. and asteroids can be very close to 273 degrees celcius under 0 Quote Link to comment Share on other sites More sharing options...
Acriku Posted October 31, 2002 Share Posted October 31, 2002 Of course nema, but still technically there would then be life.. Quote Link to comment Share on other sites More sharing options...
Edric O Posted October 31, 2002 Share Posted October 31, 2002 ...life in suspended animation. Quote Link to comment Share on other sites More sharing options...
nemafakei Posted October 31, 2002 Share Posted October 31, 2002 There would - but you must explain whence it came. Quote Link to comment Share on other sites More sharing options...
Caid Ivik Posted November 1, 2002 Share Posted November 1, 2002 Acriku is right though, Bacteria were found on asteroids. and asteroids can be very close to 273 degrees celcius under 0But only dead fossils. Possibly when a meteor hit Earth (or Mars, Europa... ::) ) some were blowed to space. Quote Link to comment Share on other sites More sharing options...
Anathema Posted November 1, 2002 Share Posted November 1, 2002 Theoreticly it's possible though. Bacteria are pretty tough creatures. They even found bacteria inside volcano craters. Quote Link to comment Share on other sites More sharing options...
Dunenewt Posted November 1, 2002 Share Posted November 1, 2002 Without the sun, there is no source of energy. No source of energy means no life.No, take the sponges that live at the bottom of the sea for example they receive no lightThey get their energy from chemicals Quote Link to comment Share on other sites More sharing options...
Dude_Doc Posted November 1, 2002 Share Posted November 1, 2002 Absolute zero does not exist. Sure, we can freeze the universe, theoretically, but still, the atoms would continue to "live". If we would freeze all atoms, the universe would collapse... and that's what's going to happen: TOMORROW!!! Hahahaha... Quote Link to comment Share on other sites More sharing options...
Terror Posted November 1, 2002 Share Posted November 1, 2002 Without the sun, there is no source of energy. No source of energy means no life.No, take the sponges that live at the bottom of the sea for example they receive no lightThey get their energy from chemicalswell, but it isn't that cold there. i mean. Molecules don't move at - 273 degrees celcius. Blood and any other fluid would become solid. So a star is needed, no matter what. Unless ofcourse you have technology to warm things up. But only humans have that, as far as we know Quote Link to comment Share on other sites More sharing options...
TMA_1 Posted November 1, 2002 Share Posted November 1, 2002 You have a point about the sun nema but there are creatures who are chemoautotrophs. They take sulfer and other chemicals to produce ATP molecules. They live near thermal vents which give off extreme heat. So the sun isnt always needed. Also the meteor that was found with "bacteria fossils" is extemely in question. They don t know if it is true bacteria. Most likely scientists say, it is a natural rock formation. Bacteria leave a different kind of fossil then what was found in the meteor. Quote Link to comment Share on other sites More sharing options...
nemafakei Posted November 1, 2002 Share Posted November 1, 2002 Ah, but where does the energy for the thermal vents come from? If the sun never happened, planet cores would be no more than (at a guess) 100K (-173 Quote Link to comment Share on other sites More sharing options...
Dunenewt Posted November 1, 2002 Share Posted November 1, 2002 Bacteria-fossils have also been found on Mars Quote Link to comment Share on other sites More sharing options...
TMA_1 Posted November 1, 2002 Share Posted November 1, 2002 well in evolutionary standpoints, without the sun, no planets would form. so the sun is extremely important. Quote Link to comment Share on other sites More sharing options...
nemafakei Posted November 1, 2002 Share Posted November 1, 2002 There's no necessity for a sun to form - just a few planets. It's hard to prove this by example, because this type of system is cold and dark... Quote Link to comment Share on other sites More sharing options...
Caid Ivik Posted November 4, 2002 Share Posted November 4, 2002 But what will cause matter to form into planetoids? There is needed one larger gravity point. Quote Link to comment Share on other sites More sharing options...
Acriku Posted November 4, 2002 Share Posted November 4, 2002 Just find some really big rocks formed from colliding asteroids and call them planets? Quote Link to comment Share on other sites More sharing options...
