how long until I get to respond to her attacking my friends with an over-sized attack on hers. I say "over-sized" because I'm not trying to get even. I'm trying to destroy them totally to prevent them from ever accumulating another point during the remainder of the history of the universe.

probably fairly quickly. i would estimate that most life would die out within 92 hours, but humans might survive off nuclear power for a while, maybe 2-3 years unless we can pull our shit together.

>>10570736
As long as we keep CO2 around 350ppm we'll be fine.

Sun disappearing from existence without causing damage as it dwindles away, I believe a well organized humanity could survive provided the solar system would continue to be stable in terms of gravity-motion. Well at least according to physics we are officially taught a sun-light disappearing would be the least of our problems, it would cause instant destruction and obliteration of a lot of the objects within the solar system!

Without light we can survive, it's the other one we would not! Again that is if the sun does indeed affect the planets stability!;D

Long live the Sun

sun's light takes about 8 minutes to reach this planet, so why not go where this light goes? we must travel 8 minuets per hour to keep where the warm is

>>10570736
8 minutes until Earth notices that light and our locus of orbit are gone. Earth is now by definition outside the habitable zone. We keep our atmosphere, but temperatures plummet to really fucking cold. All life unable to keep warm dies within a day, all plant life but kept alive with indoor light/heat dies too.

So yeah, day or two.

Even disregarding the probably near-immediate and catastrophic effects of such a loss of solar gravity on a system-wide scale, we really wouldn't need to worry about trying to survive without light.

The Sun provides the heliosphere, the solar wind which acts as a buffer between the planets and the incredibly lethal environment which is interstellar space.
Without the Sun, Earth becoming a rogue planet cast out into interstellar space would be a near certain death-sentence for most forms of life.

So without the sun, instantaneous or within minutes death at worst, a few days at best.

It is not the lack of light that would destroy all life it would be the lack of solar system stability, gravity, lack of balanced force. The disappearance of the sun would according to physics based on the accepted astrophysical model would destroy the solar system! Instant chaos, tides, fires, loaners crashing into eachother, objects crashing...

Instant destruction, forget the eight minutes of light reaction to fizzle out, instant destruction!

I put on a warm coat.

Anywhere from 9 minutes to few years.

The earth will get hurled into space like letting go of a spinning rock tied to a string the sudden change in acceleration will destroy everything instantly the planet will become a heaping pile of rubble

I enjoyed the old sci-fi story "A Pail of Air", perhaps you might too, OP. It regards this issue

how long until I can finally build muscle?

>>10570963
the sun will disappear first

>>10570833
Travel the distance light covers in 8 minutes, per hour. Which is approximately the distance between earth and sun ~93 million miles
So 93 million mph and we'll be able to keep up.
Just uh, paint flames on the side of the spaceship to make it faster

This actually we're all dedbois

>few years
More info on this?

>>10571038
Within few months, most of the plant life will die off. This will kill off many of the herbivores, which will kill off carnivores.

What's left is not enough for humans. If we suppose few humans survived underground for a year or so, they will be severely rationing food supplies.

not long

>>10571054
How the fuck is the plant life even gonna last months?

The only forms of life that even have a chance of surviving longer than a few days would be those clustered around geothermal vents in the deepest oceanic trenches.

>>10571106
Some are more resistant than others, but again, most will die off I said. Big trees can survive for few months without any sunlight and that's because the structure of the tree itself is bit large and robust.

Temp will be near absolute zero though. It'll make Pluto look warm.

>>10571173
Near absolute zero after a few months? What? No way Earth would get that cold that fast. It'd probably get to like <-150°C, but the colder the Earth gets, the more slowly it'll cool.

>>10571157
A sequel of sorts

This too
A lot of this is speculation and assumptions but here we go

>>10571173
>>10571186
In a year or two it will be ~ -100C and in maybe 100 years ~-150C or so. The earth's core will continue to generate heat and thus slow down the process. Maybe few thousand years from now, it will be ~-200C or so.

>>10570736
he died like 300 years ago and we're still fine dumb monarchist

>>10570736
Anyone who can't find shelter after the first day will probably freeze to death in hours. After 4 days many people will likely start dying due to dehydration because of frozen water. After a week anyone who doesn't have food stores will start dying from hunger. Within the first year most humans will probably be dead. However, some military might be able to survive for quite some time. Submariners for example would have enough power and heat for many years, and would just need to surface frequently enough to restock food. It shouldn't be too hard to find supplies because competition will all but vanish by the end of the first year. Some groups of humans may survive decades.

Sea life will probably survive thousands of years, with sea life that lives near thermal vents not even noticing any difference. This is especially true for sea microbial life, which will flourish on the surplus of dead sea animals that usually live near the surface, died, and sunk to the ocean floor.

>>10570736
Deep sea thermal vent niggas will still be alive until rapture.

>>10570935
There would be no sudden change in acceleration, at least not from our perspective. The force that holds you (not the Earth, but you personally) in orbit around the sun is relatively small compared to the force of earths gravity. We hardly even notice we're in a rotating frame of reference.

What is the percentage of plants that consumes oxygen during nighttime?

>>10570736
My question to this is, since our solar system revolves around the sun, would we still continue the same path of revolutions?
Would all the planets collide?
Wouldnt the sun disappearing result in the sun going super nova and consuming us all? Or do you mean just, if we didn't have a sun?

We would not have food to sustain after a while unless we relied on nocturnal plants, which rely on moon light so that is out of the question.
Our food would he depleted and the earth would be approaching 0 Kelvin RAPIDLY

>>10572137
if the sun disappeared magically one second then all the planets would just slingshot away on their current trajoctories and possibly lead to some collisions

>>10570736
It will take 8 minutes before darkness cuz the distance between the sun and earth. not an answer to your question tho...

>>10571732
If the earth were to stop in its orbit, would that not hurl everything on its surface off into space because of inertia?

Probably as long as it takes us to collide with some body in the solar system given the disturbance from the lack of the sun's gtavitational pull.

what will kill the thermal vent life after a few thousand years?

>>10572235
Earth wouldn't stop in its orbit. It would maintain its velocity after the sun vanishes with minor perturbations from Jupiter (depending on where jupiter was in its orbit in relation to Earth at the time) continuing in a mostly straight line.

Everything on the surface already has the same velocity as the planet, we wouldn't feel anything except a sudden chill when the sun turns off

>>10570935
No.
>>10571732
Correct

Assuming the mass at the center of the solar system doesn't dissapear: Nearly all human life would be dead in not much more than a few hours. Supposing someone goes deep underground and has a massive stockpile of food and heaters, about as long as they can go without running out of fuel and food. Maybe a few months.
There's no chance of anything looking even remotely like surviving. The amount of heat you'd require just to grow your own food is ridiculous.
