This topic is probably talked to death on here, but I never get

>>8131882

it'd get pretty fucking cold pretty fast 2bh lad

>not to mention dark as shit

>>8131885
No shit, but how long could we survive for?

I'm talking about people trying to live underground, underwater, on the surface etc.

>>8131882
I hate this faggot but he answer the exact same question in this video: https://youtu.be/qF3ejw7JJuc

>>8131888

you know how the temperature drops a bunch when the sun goes that

imagine that except it doesn't stop

why do you think the heat would hold underground for any worthwhile amount of time?

>implying anyone is going to calculate the practicality of how long it'd take until everyone froze to death everywhere during all circumstances

>>8131895
Don't answer the question or anything, whatever you do.

>>8131894
Thanks.

>>8131882
>survive
Thats absolute extinction anon, see with no sun there are no plants meaning no animals meaning no food web meaning everything dies except the bacteria.

We can easily survive in bunker with nuclear reactors heat and energy

>>8131927
Jesus Christ this board is useless and can't into the concept of questions and answers.

>How LONG could we survive?
>"Anon, we couldn't survive."
>But how LONG could we?"
>"We couldn't."

Is it possible to convert moon into small sun?

astronauts in ISS could survive at least 3 years.

>>8132090
ISS use solar energy

>>8132090
With what power source?

>>8132098
Oh, well then some bunkered nuts who prepared for nuclear war with a geothermic generator could survive as long as his reserve permit it.

>>8132103
I don't think most bunkered nuts have prepared to generate sufficient heat for their bunker in absence of a sun, however, this is the best answer proposed so far.

Earth makes heat.
Dig deep.
Heat exchangers on or near the surface, and deeper in the crust.
Heat engines.
Power. Light. Crops. Industry.
Crops likely move to microbial sources.
Indefinitely. So long as we get through the initial construction.
Likely 99% of current human population is boned, though.

Also presuming earth doesn't get blasted by random space shit or fall into jupiter or something.

Assuming the lack of gravity hierarchy doesn't completely kill us by planetary collision with one of our neighbors we would probably have half a day at best before the entire planet reaches unsustainable levels for every living thing.

And by the way we humans would probably all die within the first few hours. The half a day time lapse is for the deep sea critters who are sustained by chemical processing by those vents.

No piece human tech I'm aware of can function in such low temperatures and no facility I'm aware of exist to cope with independent survival of the sun outside the deep sea of course.

>>8132120
It would take way more than a day for a planetary collision, which is pretty unlikely regardless.
And we survive half a day without the sun fine, every single day there has ever been.

>>8132124
>And we survive half a day without the sun fine, every single day there has ever been.
The sun is still heating the other half of the planet, which is carried through the atmosphere. Not exactly the same as a complete lack of sun. Not everything is about how much light hits the surface, that's a very simplified view.

>>8132120
What are the chances of planets smashing into one another when they're all pretty much just going to make a B-line in whatever direction they were relative to the Sun?

Would it be possible that a new system with planets orbiting Jupiter could be formed in this situation?

>>8132189
What?

>>8132132
Zero. Space is big.

>>8131882
Some could survive indefinitely.
Geothermal power
Grow lights
Oxygen production (plants, water splitting)
CO2 scrubbing (plants, ?)
sealed or positive pressure environment
underground or super insulated
EVERYONE ALIVE?
Powerlines repaired and running after most of the water freezes out of the atmosphere.
Plastic and duct tape to seal houses, electric life support units mass produced.
Electric cars with Mythbusters golf ball pattern insulation or just insulation.
Geothermal and Geothermal-Nuclear plants provide the power.
Nuclear only powerplants can't keep cooling water, they evaporate it away. They'd have to modify and build more air cooling towers, rather than the evaporative ones they have now.
Combine oil drilling, heat pump and other tech to get home geothermal heat, power and life support. Losing power is fatal without your own backup geothermal unit.
Underground shelters couldn't be dug fast enough, houses would be insulated in every way possible including retaining walls and backfill. Drilling companies would be drilling geothermal wells. Every house should have two sources of power and life support. Oxygen lines with connections could be put along main streets so you could still get to stores; 1 human power uses less oxygen than 200 horsepower and they're already supposed to be making enough oxygen to keep you alive already.

>>8132207
Are we above Jupiter escape velocity? Or would we orbit Jupiter?

>>8132124
>and we survive half a day without the sun fine, every single day there has ever been
>the sun disappears at night

>>8132189
No. Jupiter's gravitational pull is insignificant (26 m/s^2). It could probably* sustain bodies as large as Mercury as its moons, top.

*probably not

>>8132086
Yes.

You all fags are talking about temperature, and are forgetting something much more essential: gravity.
As soon as the sun "disappeared" (in a metaphysical way) earth would be cast away by its own speed into the void. Even, even if we didn't hit any asteroids on the belt, the sudden speed would vastly destroy our planet's surface and atmosphere.
If the disappearing of the sun was realistic, rather then hypothetical, the huge amount of mass that suddenly vanished into space would cause a rare event of gravitational disarrangement which would pull planets apart.
And even if we are talking about temperature only, dumb ass op thinks that we survive "half aday without sun every night", like the sun actually disappeared after sunset.
We're talkimg about our source of heat. 97% of earth's warmth comes from the sun. As soon as it disappeared, given the 8 minutes for the last emitted radiation to reach us, the temperature surrounding the earth would be the usual 3 kelvins that warms the universe. We would lose heat like a incandescent metal put into cold water. We wouldn't last a day. Maybe not even hours.

>>8131882
By most estimates it would take a week for the planet to drop below freezing....In a year get somewhere around a -100F....Tress would be around for quite a while (hibernate--store)...coated scavengers would last for while until the cold got to them....Move to Iceland or set-up a nuclear power plant heating us....Roughly millions of years until we reached -400F...So oxygen would be around for a while....Not a lot of time...Most would die...But some survival is possible...

>>8132396
We are moving at the free fall velocity with respect to the sun....There would not be a "sling shot" effect...No sudden acceleration...There is not added energy to the system....We simply continue in a straight line at our current speed...Our atmosphere is handling it just fine and will continue to do so...

>>8132396
>the temperature surrounding the earth would be the usual 3 kelvins that warms the universe. We would lose heat like a incandescent metal put into cold water. We wouldn't last a day. Maybe not even hours.
Wait, do you actually think the Sun warms the Earth by conduction?

>>8132461
Irradiation. When it ceases, what happens?
Ill tell you what happens. We freeze.

>>8132463
>Irradiation. When it ceases, what happens?
Very gradual cooling.
The Earth is fucking huge, and it's not THAT hot. The land and ocean is a large reservoir of energy, which is why we don't freeze every night.

1. Burrow deep into the earth
2. Build underground nuclear reactor
3. Harvest plants using nuclear energy
4. Live as mole people dependent on uranium

Etc

>>8132119
Maybe if the Earth wasn't flat.

8 minutes

>>8132231
Surface gravity has nothing to do with the ability to keep and capture moons.

Saturn is smaller than Jupiter and has a moon larger than Mercury.

>>8131882
>What kind of technology could sustain us longer?

Ignoring the massive death counts until we reach equilibrium, we won't need any new technology.

The extra necessities are heating and lighting for crops. Maybe atmospheric enchantment. But that's it.

guys, everyone is saying that we could survive underground, but that is impossible.
if the sun will stop burning all the atoms in the sun will go to each other and form a black hole...
so we will got sucked in that black hole and we will ripped out in parts cause the gravity in that black hole...
so probably like few seconds

>>8133837
we would continue to orbit that black hole just like we orbit the sun now.

>>8133847
no cause like the gravity is so high at that moment that nothing can hold us...
so we won't turn around that black hole we will just got sucked in just like the stars and the planets in the middle of the milky way...

>>8133857
mass doesn't chance if you compress a star into a black hole. gravity only cares about mass.

>>8133871
not in a (near) vacuum right?

>>8133837
>sun-->hearth = 8mins at light velocity
>few seconds

>>8131895
>why do you think the heat would hold underground for any worthwhile amount of time?

because the entirety of the core of the earth is heated by radioactive decay, not by solar radiation you twat.

OP, humanity could and would survive for quite a long time, given that we already have deep shelters in place around the world for other reasons.

The biggest problem, other than going bat-shit crazy, is how to regear pretty much all of technology towards subterranean production, and that includes sustaining a large enough population to support that kind of thing.

The real killer is going to be when the atmosphere starts freezing out. That's when things get really interesting...

>>8133879
wut?

>>8133871
gravity cares about mass and distance.

in the case of the sun -> black hole tho, we would be so far away it wouldnt matter.

>>8133998
Turning the sun into a black hole wouldnt change how far away we are from it

>>8134009
jesus just never mind if you dont understand what my point was.

red dwarf stars will burn for around a billion years?

it would be dark, and you'd have to live on a planet pretty close to the star, so it would be a big oppressive red thing taking up lots of the sky

but you would survive for longer than your brain can really imagine

>>8134043
What the hell was your point?

>>8134057
if a black hole suddenly formed from our local star, it wouldn't change the orbits of the planets

we would have the same masses moving at the same velocities and everything would basically be the same


we would get some really sweet gravitational lensing (sp) from our local black sol, before the water in the air froze and we died

>>8131895
you are a fucking idiot

You and your question is retarded

Do you honestly expect kind of exact timeline for this?

Do you think there's some kind of algorithm to calculate the exact amount of time before extinction?

Fuck off back to /b/

>>8131882
Average surface temperature would halve every month until the surface froze
Top of all oceans would freeze solid, but would insulate the bottom layers of ocean, keeping it warm and some life would survive
If humans could tunnel deep and fast enough, the heat from the Earths inner core would keep the inner crust warm enough for life to continue for millions of years, what kind of and at what quality of life is debatable but it is doable

fucking kill yourself you huge flaming faggot
