A bit - probably weeks to months.
no? more like 24 hours, and only in tropical places. It goes from 85 to 55 in 12 hours right now in reality world
you’d have 24 hours to
Comment on Gottem. :)
rockerface@lemm.ee 4 weeks agoA bit - probably weeks to months. For the second question - 8 minutes for the Earth, since gravity propagates at the speed of light

I honestly think you’re forgetting the atmosphere and like, physical ground under our feet. It doesn’t generally drop to 0C overnight unless it’s already pretty close to 0C because of the heat trapped in the atmosphere and emanating from the earth’s core. It’s going to be more like a week for most places.

no im not, you’re forgetting that the sun exists
Max-Min temps (F) yesterday across 3 different continents:
Lucknow 82-53
Mandalay 90-67
Kisangani 91-76
Porto Velho 85-77Temps drop by 22 F at night (avg) around the equator. Most tropical land reaches freezing in 1.5 days if the sun vanishes. Forget temperate.
Best case scenario is Tropical rainforest since water holds heat. Middle of Amazon gets “only” an 8 F (4.4 C) drop in 12 hours, so 3.3 days to reach freezing.
Keep in mind that these drops include the “wind down” sun time of evening, which means that these times are slightly slower than the real times, since the sun would vanish suddenly instead of gradually setting
Also keep in mind that these temp drops occur right now, in reality meatspace, despite “the atmosphere and like, physical ground under our feet”. (both of these exist)

Actually, on second thoughts, this comment explicitly proves that you’re a reactionary hiding their lack of investigation behind accusations of immaterialism - just by applying your own logic to real world numbers, you’ve gone from a day to half a week. You have no place opining on this subject.
ProfessorOwl_PhD@hexbear.net 4 weeks ago
Yeah, you’ll notice that your “massive” 22°F is the difference between direct sunlight and no sunlight. Do you think there’s another sun to take away after the first one, to get rid of even more sunlight and drop the temperature another 22°?
Why don’t you believe that physical materials are capable of holding heat energy? Why did you latch on to atmosphere and ground instead of the biggest energy store on the planet, the ocean (you don’t need to answer that we know it’s because those are the ones I named)? Why do you think that the temperature difference between day and night - sunlight and no sunlight - is the same as the general rate at which energy is lost from the planet? Have you not ever been outside at night to discover the largest part of the temperature drop happens as soon as the sun disappears?You’re doing a very good job of the typical liberal application of raw, familiar logic to a new situation, but the only part of it you actually understand is that the sun supplies lots of energy, and haven’t made it any further than that.

And the sun doesn’t generally blink out of existence. Think about how much energy is on the other side of the earth, it’s not like the two sides of earth are separate they are one huge interconnected energy system. What happens on one side affects the other
ProfessorOwl_PhD@hexbear.net 4 weeks ago
You are also forgetting the atmosphere and ground (and oceans, of course) - It being one huge interconnected energy system is exactly why I’m saying it would take longer. This guy’s calculations reckon we’d lose about 1 degree per 12 hours. January’s global average temperature was around 13°, so that’d be 6 and a half days. July last year it was 17°, so that’d be a whole 8 and a half days. It’s going to be more like a week.

The irony of a guy with PHD in his username not understanding that the Sun blasts the Earth with an absolutely unreal amount of energy

Expanding a little on the last part, Earth’s orbital velocity is about 29.8 km/s so that’s the speed at which we would suddenly be leaving the former location of the solar system in a direction that depends on what time of year it happened. Regardless of direction though, the escape velocity of the Milky Way around where we are is about 544 km/s so there’s no way we’d be leaving the galaxy. On the other hand the plane of the galaxy is only about 6 degrees off from the galactic center at the moment, so if this happened at the right time of year (don’t know when that is) we could launch somewhat towards the core. We would not however get very close to it because the sun’s own orbital velocity is about 230 km/s so we’d still be in close to the same galactic orbit overall, just potentially a bit more eccentric.

Do you think Jupiter would take over as our center of the solar system? Hopefully it doesn’t sling us into deep space or another planet
Klear@lemmy.world 4 weeks ago
I wouldn’t sling us into deep space because we are in deep space and will continue to be in deep space.
burgersc12@mander.xyz 4 weeks ago
I meant like away from the rest of our planets. Space= above earth. Deep space= beyond solar system. No one considers earth space
