What would happen to the earth if the sun disappeared? Can we continue to reproduce?

If the temperature of the earth will eventually drop to around 10 degrees above absolute zero once the sun goes out, give or take, those who cannot protect themselves from the cold will die first, and the rate at which the earth cools will vary greatly.

After 24 hours, our ecosystems and infrastructure are tuned and designed to handle a night, a period of 8-16 hours without the sun, after which we get 8-16 hours of sunshine, in the Arctic and Antarctic regions, winter's There was a night in the middle that lasted for weeks and it became so cold that we, as humans, with all our technology, could not survive there, and once a year, as winter approached, the team equipped with the Antarctic research station had to Abandon base for a few months and return after the sun starts spending more time in the sky again.

The Earth's surface won't get super cold right away, but it will quickly, and I think somewhere on the third day, it will start to get uncomfortable for people who don't have a good source of heat. After a week, the average Earth temperature will be freezing, around 0 degrees Celsius, and it will vary greatly depending on where you live.

It will stay warmer near the ocean for longer and get colder the farther you get away from them, obviously it gets colder from the cold, it takes 1-3 years for them to freeze.

We can go this way for months because the earth will slowly cool down, but after a year the average surface temperature of the earth will be -73 degrees Celsius, however, many people will run out of food and water before that happens.

You can survive longer if you have a source of heat, but you need food and water, and everyone who somehow manages to survive the cold without a constant source of food and water will when their food and water run out die.

If someone lives near geothermal activity in a well-insulated structure and manages to get both heat and electricity (light), and has a hydroponic farm, they can last 10 to 20 years, and then the oxygen starts to get cold enough to get cold enough into liquid, into rain made of oxygen, and then as it gets colder, it turns into snow.

Imagine going outside and getting a bucket of air to inhale and set off a fire so it warms up and you can breathe, so while the earth still has plenty of oxygen, it doesn't come in a form that you can breathe. Let's say after about 30 years or so, everyone dies.

Geothermal vents hold microbes and other life on the ocean floor that are too deep for the sun to reach them and use other means to survive. They never notice that the sun is missing and continue as usual.
