Theretical scenario.....

Tomorrow mid day as everyone is going about their day the sun suddenly burns out. Its gone and we have no idea why it happened.

How long would it take for everyone to die? Days? Weeks? Longer?

>> No.2213204

I bet it'd be a few days before all land is frozen over, but it may take longer for deep in the ocean

Let's go find Atlantis

>> No.2214117

We would run out of oxygen after 8 minutes. Or at least I think that's how long it takes sunlight to reach us.

potentially years.

the last survivors would presumably eat the frozen corpses of everyone and everything that died before them.

eventually we'd run out of things to burn for heat and light, and power plants would cease to operate for lack of maintenance, and the last humans would freeze.

Few days. People would survive a bit longer because petroleum would power shit, but it'd all go to hell in a handbasket within a week. The Sun is overwhelmingly the reason life exists on this planet. It goes, we go. Quickly.

>> No.2214135

since gravity is instant, if the sun were to disappear suddenly, the earth would IMMEDIATELY be affected by the lack of gravity, causing the earth to crash into the moon and destroy mankind.

shit god you mean the earth would just drop down oh shit

gravity also works under the speed of light, believe it or not.

OP said that the sun "burns out." Its gravity is not necessarily changed. And even if it did vanish suddenly, it's gravity doesn't affect the Earth much, apart from making it move in a big ellipse... and ocean tides.

The heat problem is what you'd need to be worried about. Our atmosphere wouldn't go anywhere, and it would retain heat for maybe a day or so. Think about it -- when the Sun is on the other side of the Earth (a.k.a. "night"), the temperature outside your house doesn't immediately shoot to absolute zero.

Our best bet would probably be to dig straight down as fast as possible... tap into geothermal. But I agree with this, mainly: >>2214128

>> No.2214243

Biggest problem would be crop failure. Hooo boy.

>> No.2214288

eventually the atmosphere would start freezing out, then even hiding underground won't do much because liquid, cold air would creep down through every gap and cool things rapidly.

We have no sustainable, easily accessible power source to keep on living, there would be no food chain to keep us fed etc.

We'd basically have to construct something that's more self-sufficient than any spaceship. Sure, we could harvest liquid air and rocks for raw material and as containment vessel. But that's it. We'd need a power source (geothermal energy would need a gigantic plant to supply enough energy to grow food from artificial lighting and sustain humans. so it probably has to be fusion), we'd need people to keep everything running, we'd need enough room to not just survive but to advance civilization further.

It's impossible with our current technology and certainly not doable within 12 hours.


We'd be very very screwed. A huge percentage of humanity would be dead within days. All of humanity would be extinct within weeks.

Yes, even our people on the ISS. Remember, they run on solar cells.

People in nuclear subs will probably survive the longest, but the ocean surface would freeze out over their heads, so they can only await their icy deaths down there.

That's not a theoretical scenario, that's a magical scenario. Hence, fuck off and all you people who are answering are stupid too.

Learn the difference between theoretical possibilities and magic.

Shut up and leave us to our ponderings.

>> No.2214413

I think we *could* last quite a while... We have pretty great capacity for heat manufacturing,

But plant and animal life would invariably die out within weeks or months, and then we'd be fucked.

More importantly, I don't think we *would* survive for more than a few days.
Panic would destroy civilization and we'd be fucked.

We send a ragtag bunch of misfits on a space ship to deliver a nuclear device into the sun to restart it obviously.

yeah, the same way we instafreeze 8 minutes after sunset.

We all move to jupiter and learn to enjoy brisker temperatures.

>> No.2214451

It's easy to find heat if you dig for it. If we had a few years to prepare, we might be able to sustain mankind (at some small population level) through a new food chain that doesn't rely on the sun.

>> No.2214515

We build big fucking rocket engines on Australia, pour all the oil into it (ALL THE OIL!) and set sail to the next closest star.

In the meantime, we enjoy our free cryogenic sleep. Hopefully the computers will align the Earth into proper orbit around the new star, and we'll defrost and get back to work.

If we're talking the mass of the sun is still there, but it stops emitting solar radiation... the earth's temperature would drop to insanely low temperatures pretty fuckin' quickly. Before our planet became a big ice cube there might be some kickass atmospheric/ meteorololological shit going down.
