I recently watched this program on NGC. Basically a neutron star is collision course with earth and it was discovered 75 years in advance.
Then the program lays out a scenario of what could potentially happen and how our reaction would be.
It is hugely interesting to watch but i would also like to hear what others think. Do you find this solution they found plausible? Do you think it would be the way the world would do it. How would the government be in the spacecraft is very interesting as well. Whatever you think about it.
It is well worth the time to watch because it is both hugely entertaining as well as thought provoking. It is not just a doomsday scenario but touches on the matter of interstellar travel as means of the continuation of the human race.
