I saw a program the other day which said that the planet Mars lost most of it's atmosphere when it lost it's magnetic field. It said that the field deflected harmful solar winds preventing them scouring away the atmosphere, but it lost it's field (...) (21 years ago, 10-Jun-03, to lugnet.off-topic.debate, lugnet.space)

(...) That sounds a lot like the premise of the recent movie The Core, but I saw a geophysicist on TV talking about it, and how he liked the fact that recent movies have been inspiring kids to get into science, but he said that in this case he (...)

(...) Blow the planet up, hope that gravity reforms enough material into Mars, and have the resultant material heat up from the process. That would be more practical than attempting to alter the orbit of Mars I would imagine. :-) If you had the (...) (21 years ago, 10-Jun-03, to lugnet.off-topic.debate)

(...) Entering extrreme geek zone OK let's do the math every thing is metric radius of the earth = 6378137 meters figure the "core" is 1/4 radius out 1594534.25 volume of core 4/3 * PI * R-cubed = 16982051976875485000 = 1.7e10^19 M^3 Ignoring (...)

GRIN.... (...) This is off topic for .debate... it belongs in .geek! C'mon guys! Now if you want to debate whether melting Mars is a good idea or not, that's different. :-) Personally I'm not sure it's a good idea, or necessary. There's plenty of (...)

(...) That's a brilliant idea. Instead of using nukes to deflect asteroids heading for Earth, find the biggest thwacking great asteroid you can find and deflect it straight at Mars and smash it to bits. Then wait for the remains to coaless, cool (...) (21 years ago, 10-Jun-03, to lugnet.off-topic.debate)
