Question

What happens if you have to use the bathroom?

Community Answer

Many shelters have bathrooms equipped with them that connect to a septic system. It's possible if you don't have a bunker that running water will stop working, so you can manually flush your toilet and fill it with buckets of water afterward.

Question

Will humans survive a comet impact?

Community Answer

If a 60 kilometer comet did make impact with the earth, all life on earth would be extinguished. If the comet was smaller, there's a good chance many people and other living things could survive.

Question

What percentage of us would survive?

Community Answer

It depends on how large the comet is and where it strikes, the percentage is impossible to calculate without knowing more about the strike.

Question

What happens if the comet hits my bunker?

Community Answer

It depends on the size/speed of the comet and the construction of your bunker. It might be destroyed, it might not be. It's very unlikely this would happen, though.

Question

What is the size of comet? We can see one with the naked eye or do we need a telescope?

Community Answer

Comets vary in sizes. They can be very large or very small. The larger ones are visible to the naked eye, but a telescope always helps.

Question

What if (highly unlikely) the comet that hits has aliens on it?

Community Answer

They will likely die on impact, but if they did survive, try to be friendly.

Question

What if I don't live in a place where guns are legal?

Community Answer

Keep knives on hand, or any blunt objects you could as a weapon. An archery set might be useful as well.

Question

What if it hits while I'm at school?

Top Answerer

You will know beforehand and school will be closed that day. If a comet hits when school is open (highly unlikely), then follow the directions of the teacher.

Question

What if the aliens have better technology and kill us?

Community Answer

Try to reason with them! Be nice and share your resources, humans have a lot of technology as well so try to make a deal with that they can use our tech and combine it with there’s so they have upgrades, this will likely make them nicer and might spare your life, if not.... then say your last words.

Question

What would happen if the comet hit the apartment I'm in?

Community Answer

The only way to survive would be to know beforehand and go to the lowest place in the building. Stay up to date and you could survive. If you didn't know beforehand, you will most likely die.

Question

How could I survive if a comet the size of Russia hit the Earth?

Community Answer

You won't. Russia has an approximate landmass of 17.1 million km squared. A comet of such size would guarantee eradication of all life on earth. It would be highly likely the earth would also end up splitting into many pieces and throwing the solar system out of balance.
