tarjei Posted December 9, 2015 Share Posted December 9, 2015 More than that surly. Would get pretty freaking cold very quickly though with maybe some strange weather. Cue burning Shakespare, the bible and the Harry Potter series, and finally eating that pot noodle and the dog food that has been in the cupboard for 20 years. On that note I helped my mom defrost the freezer the other day and we found left overs from her 50th birthday in there. She's 64 this year! 1 Link to comment Share on other sites More sharing options...

Interesting question though, We couldn't grow crops on any scale, vitamins from the sun would be bad for any living thing. I'd say, with current food storages & energy capacity, about 6 18 months maybe? Link to comment Share on other sites More sharing options...
chrisp65 Posted December 9, 2015 Share Posted December 9, 2015 Yeah, my 8 minutes might be a bit pessimistic. I guess there is some evidence that we survive facing away from the sun most nights. Link to comment Share on other sites More sharing options...

By that time the Chilcot report might have been published and climate-change campaigners will all be looking pretty smug. Link to comment Share on other sites More sharing options...

Genie Posted December 9, 2015 Share Posted December 9, 2015 I think can of pop/beer is a local thing too, most people go for tin of pop/beer? Link to comment Share on other sites More sharing options...
Stevo985 Posted December 9, 2015 VT Supporter Share Posted December 9, 2015 Are we assuming the heat from the sun would stay around after it "went out", or are we assuming no heat? Because if it's the latter then surely we'd freeze almost instantly? If the former I reckon it'd be longer than we think. I bet the heat would stick around for a while. I'd guess humans could survive (as a race) for 18 months (as in be in existence) Based on more or less nothing Link to comment Share on other sites More sharing options...

Assuming no heat, we could heat our homes/cars etc you'd think for a while at least. I guess we'd have to upspec a lot of stuff to manage. I'm assuming it being about zero degree's. Someone clever will probably tell me that it would be about -300 degrees C without any sunlight but that takes the fun out of it... Food would be an issue I'd guess. Farming would be incredibly difficult without natural sunlight. Link to comment Share on other sites More sharing options...

Farming would be incredibly difficult without natural sunlight. Well that's what I'm getting out. If there was no sun, and no heat remaining from when it was here, then the temperature would be incredibly cold. I think your guess of -300 degrees isn't far off (absolute zero is approx -270 degrees IIRC so it wouldn't be much warmer than that) But if we're taking into account residual heat then I guess some of that would stay around for a while. Food would be the issue. No sunlight = no food Link to comment Share on other sites More sharing options...

Food would be the issue. No sunlight = no food There must be a way around making some foods 100% without sunlight? Assuming not, then I guess with all the food around at any given time I guess we'd all starve to death after a couple of months tops. Link to comment Share on other sites More sharing options...

And as far as I know, everything we eat relies on plants existing at some point. Maybe somebody will correct me there... Link to comment Share on other sites More sharing options...
tarjei Posted December 9, 2015 Share Posted December 9, 2015 Also it would be very dark. Imagine how difficult it would be to light the scenes for The Walking Dead, etc. Only the Marvel shows would survive that! 1 Link to comment Share on other sites More sharing options...
Genie Posted December 9, 2015 Share Posted December 9, 2015 So we'd all die, eventally... how long would it take? Link to comment Share on other sites More sharing options...

As the link I put on the previous page said, after 8 minutes (the last the Earth would receive the suns light), then all photosynthesis would stop, meaning nothing could grow, plants being the bottom of the food chain would mean the tiny, small and medium sized animals depending on them would die, entire food chains would collapse in a month or 2. Heat isn't really the issue, the Earth has a molten core don't forget, so if you lived near a geothermal spring (like Iceland), you could keep warm for centuries. Under ground of course because without the Sun, the seas would freeze over within a few weeks. After a year, all residual heat from the surface of the Earth would be gone, so it'd be -400c on the surface, we'd have to turn into Mole people. But according to the link I posted, a small number of humans could live on for generations without the sun. You'd have to start getting used to freeze dried food though 1 Link to comment Share on other sites More sharing options...

Perhaps the most pressing issue would be the lack of oxygen. Link to comment Share on other sites More sharing options...

Big, established trees would live for years, because they don't need to photosythnesis to grow, plus, because they're so large and metabolise to slowly, they have years worth of sugars within them. Trees would be A-ok for a while Just no saplings. Link to comment Share on other sites More sharing options...
