An interstellar comet is detected, it is massive, with the main nucleus estimated at roughly 18 km in diameter. Unfortunately after many calculations it is determined it will impact Earth with 100% certainty.

Scientists fear it is too large and due to being a comet it will simply be impossible to destroy or deflect in time.

It will impact in 3.1 years.

How does humanity survive?

What happens to society?
