iain Posted May 22, 2003 Posted May 22, 2003 Dunno if anyone saw the images from the Mars global surveyor of Earth...we are bacteria on a grain of sand. here's a link to a bigger picture with us and Jupiter. Quote

catbirdseat Posted May 22, 2003 Posted May 22, 2003 I concur, trask. Lately, ol' DFA has been a nattering nabob of negativity (name the originator of that one). In the link photo, I see Jupiter and two dots. One is the earth, and what is the other? The moon? Quote
Formaldehead Posted May 22, 2003 Posted May 22, 2003 The Earth/Moon/Jupiter image must be a composite. The scale is off between the two planets. Quote
Dr_Flash_Amazing Posted May 22, 2003 Posted May 22, 2003 Challenge for Trask: make one post without referring to gay and/or anal sex, farm animals, substance abuse, lesbians, S&M, underwear, firearms, minorities, Cooper, groping, strippers, bodily fluids, prostitutes, or Dr. Flash Amazing. Your move, chief. Quote
Fejas Posted May 22, 2003 Posted May 22, 2003 yeah, and the spec of sand (our gallaxy) is one on a 100 mile log beach... un real to think of the vastness of space... Quote

Recent observations indicate rather conclusivey that the vastness will only increase exponentially over time. Additionally, the matter that constitutes the visable universe will coallesce into black holes, which will then evaporate into sub-atomic particles. Pretty grim outlook. Quote

They then get spit out, where, at the other end of the univers, maybe... so does this mean that it is constantly moving? if so where do ya sapose its going? its a state that we may never get to discover... I loved astronomy, it is a science that has queshtons that are never truly anwsered... Quote

allthumbs Posted May 22, 2003 Posted May 22, 2003 I always kinda wondered, anybody know how cold it is up there in space? Quote
Dr_Flash_Amazing Posted May 22, 2003 Posted May 22, 2003 According to Elton John, it's cold as hell, but who knows how trustworthy he is. Quote

allthumbs Posted May 22, 2003 Posted May 22, 2003 The Question: All I wanted to ask you is that if we put a thermometer in Space with no other light or heat source around and absolutely no background radiation there, what would it read? Would the temperature be really cold or what? The Answer: Yes, it would be really cold. Temperature measures the energy per "degree of freedom" (i.e. way something can move) of whatever molecules happen to be around. So, it it becomes so cold that the molecules stop all together, then this is the "absolute zero" temperature. On the Celsius Temperature Scale (i.e. water freezes at 0, and boils at 100) this takes place at -273 degrees C. We usually use the Kelvin temperature scale, where Zero Kelvin is this "absolute zero" temperature -- or -273 degrees C. Water freezes at +273 Kelvin and water boils at +373 Kelvin. If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there. Brrrrrrrr Quote
Formaldehead Posted May 22, 2003 Posted May 22, 2003 trask said: I always kinda wondered, anybody know how cold it is up there in space? "Heat" is the motion of atoms or molecules, and the amount of "heat" is expressed as "temperature". Since there is no matter in the vacuum of space, there can be no "heat", so the terms "hot" or "cold" are inapplicable. You're question asked how cold it was in space, not in a thermometer. Quote
