>>734123407 if the sun turned into a black hole of 1 solar mass the orbits of planets etc. would not change. as long as the mass remains the same the gravity felt by planets won't be impacted so nothing will get thrown out of orbit.
however the sky would go black, plants would die etc maybe a small set of humans would survive
>>734123407 IF the sun were to be turned into a black hole, the gravitation pull of it would be the same. The rotation of the Earth around the black hole wouldn't change from that of the Sun.
The major problem would be the heat lost. The dark side of the Earth cools about 20-30F at night without the heat of the Sun. You could expect a similar cooling each 12 hours or so. This means the Earth would freeze within a day or so. People could try to stay warm by burning large amounts of fuel, but it would be a losing battle.
>>734123407 They give off insane amounts of radiaton, but we wouldn't even live to see it. A star collapsing into a black hole would go supernova first, and that would be game over. We'd all be dead before we knew what hit us.
>>734124311 yeah we won't instantly freeze. but the atmospheric effects would be tremendous. a lack of sunlight would dramatically alter the patterns of trade winds etc due to a lack of convection. rainforests would die out completely and there would be no global carbon store.
>>734124658 i'm talking a small population living in a self sustained habitat, it's definitely possible on a very small scale
>>734124524 Actually, some convert to black holes without the suprnova. They're called Unnovas. They need to be a certain size, rotation, etc. There's been a recent unnova. I'm trying to find the information on it.
>>734125077 Even still, wouldn't you think we'd die from the radiation exposure long before we'd freeze? Hard x-rays and gamma radiation would partially be absorbed by the ozone layer, but I don't think it would be enough.
>>734125581 Fuck me you're thick, all the planets would continue to circle the new blackhole exactly as they do now. The mass of the black hole is identical to that of the sun, even if it were higher the orbits would not be significantly effected.
>>734125581 black holes aren't magic vacuums like in sci-fi mate a black hole with the mass of the sun can be orbited just like the sun
>>734125648 black holes only release radiation from heating up gas etc. that orbits it. it doesn't release radiation from nowhere. there isn't much mass in our solar system compared to the black hole at the middle of the milky way releasing loads of x-rays.
the earth wouldn't freeze instantly heat would be retained for a while in the atmosphere and oceans and land. we would die over a year or two probably.
Most plants & animals would die off quickly & the cold would preserve their flesh. After eating those, humans would start eating each other till a sustainable population of a few million emerged. These could go on using nuclear power & the remain fossil reserves
>>734125993 where would we get oxygen from with no plants to support a few million? literally every plant on earth would die. the place would be barren. the atmosphere would freeze and fall to earth. the oceans would freeze over. how would nuclear power plants work when the temperature is -100 degrees celsius? how can you mine for fossil fuels in a frozen ground the oil would be frozen solid
>>734125581 Yeah nope. Too much scifi-movies. The mass of the black hole is the same as the mass of the object that turned into one. It's just a lot, A LOT more dense. Just like your head. You dense motherfucker.
Also, since OP must assume Sun just magically turns into a black hole (not going thru red giant phase which would eat our planet) the answer is we'd freeze to death. So a couple of months at best. /thread
>>734126392 how the fuck are we going to build biodomes in the mass panic that has ensued? you think we will just go to IKEA and get a flatpack biodome? where will we get the materials from? anyone who isn't inside a biodome before the sun turns into a black hole will freeze to death
>>734124902 It would be the same mass, so we'd experience the same time dilation around the sun that we already do.
It's not zero, but it's barely noticeable. The sun's not massive enough and we're not deep enough in the gravity well either. We'd have to be approaching the event horizon for significant time dilation to occur.
>>734125514 The black hole in Interstellar stretches time that much due to both the fact that it's supermassive and that it's spinning at near the speed of light. There's some scientific basis for that increasing how much it warps space-time and potentially allow you to go beyond the event horizon without dying, although in reality you'd still ultimately be crushed in the singularity without the Tesseract to save you. It kind of makes sense because the beings needed them to be able to glimpse a singularity without dying, and that was the only possible way to do it (with the extreme time dilation being an unintended yet unavoidable consequence of such a black hole).
>>734127073 I'm not, since it doesn't really have anything to do with this question.
They don't really ever explain that shit in Interstellar (besides off-hand mentioning that the black hole is "spinning") so technically I'm not using the movie as a source at all. I just thought it was interesting to use "real" science to justify some events in a movie. It wasn't all complete bullshit. There's more wrong with the way space travel works in the movie and various other inconsistencies and plot devices than with the physics of it.
>>734127384 The beings led them to a place where they could view a singularity without dying. The only place they could do that is a black hole with very specific properties which would be incredibly rare. So the wormhole took them to that one place. This made sense to me.
>>734127384 The science/physics in that movie were bullshit anyways, if the gravity on the water planet was really strong enough to make waves hundreds of feet high it would have wreaked havoc with the internal organs and fluids of any human landing there.
>>734123407 Well temperatures would drop, but with earth's internal heat we could live underground. The biggest problem would be the lack of sunlight. With enough powerful artificial lights we might grow enough vegetation to sustain an entire food chain. Using nuclear powerplants and/or geothermal plants i'd say that with our current technology and with some preparation it could actually be liveable
>>734127862 The water planet's gravity wasn't that high. They said it was just slightly higher than Earth's. It's tidal forces from the black hole that caused the waves. They wouldn't necessarily feel that, just like we don't feel the tidal forces of the moon.
>>734128162 If they didn't, they wouldn't be able to save humanity. The being's goal was to both find a habitable planets and to save humanity. That system included the means to do both. It was clearly specifically chosen by the beings, the crew didn't really have a choice over where the wormhole led them. They just had to do what they could with what was found there, and they didn't have all the information.
>>734123905 Can you explain the process dear Anon? I know I should google/wikipedia it but I thought a more personal explanation by another human being will help me understand the rough idea behind it.
>>734128543 We wouldn't die as soon as the sun went dark. Like others said, the Earth would retain its heat for a while because heat isn't lost to space very quickly.
It would be a matter of years before the surface becomes completely inhospitable, though we could still find means to survive. The main problem is how many other things would die which would severely reduce our food sources. And with all plants dead, there won't be anything to replenish the oxygen. That's the kind of stuff that'll kill us, possibly before the cold does.
>>734123407 https://what-if.xkcd.com/49/ This effectively answers the question. It refers to the sun just "switching off", rather than turning to a black hole, but it's functionally the same situation.
>>734128970 There's too much stacked for it to not collapse, discomfort leads to comfort and people struggling will struggle in equal measure against each other. The few who remain will be to far in between and after that you get stuck with the garden of eden and a perfect garden. How long would life survive if it was lived? Fuck the sun, time can suck a dick too. It would be a matter of weeks before there wasn't enough room for you on the surface or below it.
>>734125648 black holes emit gamma rays when some of the gas they consume gets sped up to near light speed. the vortex emits the gamma rays out of the poles of the black hole. if the sun's rotation stayed the same, the gamma rays would be perpendicular to the Earth, and it would require a lot of gas in the general area of the Sun which there really isn't much.
>>734129628 It would've been impossible to save the people on Earth without the information the singularity inside the special black hole provided. They wanted to save the people on Earth too, I guess.
>>734129272 It's kind of hard to explain. When a star goes late into its life cycle, it's depleted most of its hydrogen fuel and the core starts to collapse due to gravity, without the outward force of the energy produced by nuclear fusion. In stars like the sun, some previously inaccessible hydrogen is pushed out by this process and start to burn again, but only in the outer shell, which causes it to expand. It burns at a lower temperature, which is what makes it red, but it gets huge.
Eventually these "shells" are shed out in layers, and then all that's left is the core, which starts out as a white dwarf and then slowly cools into a black dwarf, where it no longer gives off any light and is just a lump in space.
Most stars go through this process, though massive ones can go into supernova, and the most massive end up becoming black holes after the supernova.
Man with the amount of filth going on in b when I saw this I knew at least there is one place that hasn't been tarnished yet, and that's space. It's too bad society doesn't push for it as much anymore.
>>734123407 You can orbit a black hole just like a star so the planet would probably keep going around but the gravitational forces might fuck the tectonics up.
The real issue is that the world would freeze in just a few hours with no heat and the people with bomb shelters and stuff might last a few months but there is no coming back from no sun it's pretty much dunzo to humans
>>734123407 Actually we could move to Europa and the massive amount of heat given off by the heat would create a sustainable environment, so it would actually be more beneficial than the way the sun is actually gonna die
>>734133224 Well, the red giant is in fact hotter, but mainly because it's so big. It has greater overall luminosity and because it's expanding it also gets closer, so the sunlight that hits us will be much hotter than it is now.
In fact, the sun's temperature always gradually increases. The more the fuel is depleted, the hotter it burns and the faster it burns more fuel.
This is over the course of about 5 billion years, mind you. This doesn't account for the affects of climate change.
>>734133410 It would be a matter of hours for there be to be a noticeable change in temperature globally, but then it plateaus for a while. With direct sunlight gone, the Earth is immediately colder, but it'll hold its ambient temperature for years. In a couple decades the surface will be completely inhospitable, but that's much slower than near instantly.
Of course, plants will die very quickly so the basis of the food chain collapses almost immediately. Life becomes unsustainable barring unlikely scenarios.
>>734124173 >A decade or two I'll bet on "cold war" in the first 5 yrs, but yeah a small population could survive in a bunker, except it might turn into ep 2 of black mirror in order to retain electrical goods.
>>734134054 True, but it wouldn't be impossible to humans for live on the surface for a while still. They would be temperatures we could adapt to for a decent while. Of course, it'll gradually get colder and colder...
>>734123407 When we enter the black hole we don'\t see nothing for a few minutes as we travel on and on we see a few horny intergalactic shamans masturbating each other furiously cumming all along the tunnels so we keep on slipping through it as we go on in about 10 minutes if you look hard enough from far away you see the glow in the dark CIA niggers laughing at smiling at what we just did as we go on and on you realize there's this massive stink then in a blink of an eye innocently we slip out of your mother's gaped shit hole you can hear her moan then all of a sudden you're dropped with andy sixx's log of shit into the canal abyss.
>>734124424 To follow up on this, I would guess it's lasts a bit longer, since once we hit freezing, the oceans will have a lot of heat to give up before they freeze out.
As the oceans freeze entirely (perhaps a week) the surface would gradually cool, with a few bumps. When CO2 starts freezing, we lose its benefit, and the cooling accelerates. When N2 drops out, air will be unbreathable, and cooling accelerates again. Underground shelters won't help much beyond this point.
Deep-sea organisms would survive the longest, but geothermal vents wouldn't be able to keep the whole ocean liquid. Possibly there would be enough heat from lunar tidal warming / geothermal sources to keep a very thin layer liquid near-indefinitely.
If there is life on Europa / Enceladus, it would probably never know about black hole sun- their source of heat is mostly non-solar.
>>734123407 Our sun is not powerful enough to induce a black hole i think, i might be wrong. But the thing going supernova would off us first. Unless we had a robust space based lifestyle where we could leave our solarsystem untill it settles.
50 years tbh we could all just live underground we can go near the lava for warmth and have alot of canned food to eat use the lava to cook and the water underground to drink wash etc so maybe 50 years probably also it wouldnt be that cold since wind cant go underground
>>734133454 Why go to Europa? An iceball Earth wouldn't be so different, and would overall still be more habitable for humans. Earth's oceans will similarly remain liquid under an ice shell due to geothermal energy and the ice also providing insulation. Not to mention that Earth will continue to provide its own magnetic field that will also protect us from radiation over the coming generations.
If we were able to be prepared, humans could potentially live for a very long time on Earth after the sun goes away, But the key word here is prepared. We'd need to have the shelters ready and already self-sustaining before shit goes down, because society and the natural ecosystem will almost immediately break down.
But we could harness geothermal energy for countless generations. It's not an infinite energy source, but it's certainly provide enough for us to continue as long as we've been around. But like I said, we have to already be prepared to harness it efficiently and sustainably before the event ever happens. Otherwise, we all die.
>>734134706 >it wouldnt be that cold since wind cant go underground The surface will eventually get so cold that the atmosphere condenses and freezes in the surface. We won't have to worry about wind. The surface will be exposed to the vacuum of space.
>>734134920 I'm not saying we wouldn't all die. Just that it would take a while. We'd have a few years to watch everything fall apart and then freeze to death, as opposed to immediately freezing to death within a few hours.
>>734135284 if freezing is issue then why not go into space and go into sun's core where hot if sun is no more then the surface of the sun isnt hot which means we can go through it and go to the core which is very hot and bring plants for oxygen and food
>>734134764 If we could get to Europa, we'd probably have better chances. Europa's "habitable" zone is maintained by tidal warming from Jupiter. Earth's current habitable zone is maintained largely by insolation. Would Earth retain a thin deep-ocean from Lunar tides & geothermal release? It's possible, but I've never seen that modeled, and I don't know how realistic it would be.
>>734123777 Actually it is. Besides, black hole can have any mass. >>734123407 Orbits wouldn't change, so we would slowly die due to the lack of sunlight. If majority of the population dies out quickly enough a small population could survive nearly indefinitely by synthesizing everything they need. Truly indefinitely if fusion reactors get invented by that time.
>>734135707 >Besides, black hole can have any mass. Technically that's true, but the mechanics to turn objects of a certain mass into a black hole are just not going to happen naturally. The sun isn't massive enough for that to happen. It takes stars like 8 times more massive to turn into black holes at the end of their life cycle.
Dumb picture. They should just rename black holes to something else, because people who don't know shit see the name "hole" and assume shit. It's not a hole. It's an object just like anything else, except it just happens to be beyond a certain mass threshold where weird things happen with light and other things. It's not a fucking wormhole or whatever else you saw on TV.
>>734136305 Not exactly, but sort of true. Black holes are gravity wells with no escape. The object itself is extremely small (or even infinitely small), but its influence in reality in three-dimensional, so the event horizon is three-dimensional as well, making it a sphere as opposed to the 2-dimensional black hole you often see depicted in fiction. Imagining them as actual holes in space time is an expression of their function in two dimensions, because it's harder to picture in three dimensions.
>>734129628 >>734129864 I thought that, additionally, that particular black hole provided the proper 'environment' for the beings to 'implant' the transdimentional tesseract, probably because of how the laws of physics 'break down' inside them.
>>734136857 Possibly. Inside the black hole is kind of beyond time and space, which suits their needs better because according to Cooper they can't find a specific place or time. Which means it would probably work inside any black hole, but it had to be one where the ones going in could survive the trip so they could actually use the Tesseract to send information outside the black hole (which would be otherwise impossible).
