A NASA research scientist has warned that an asteroid or comet strike of sufficient size could spell the end of the world, its impact touching off an extinction level series of events, simply because the Earth is unprepared to defend itself against such an occurrence.
NASA scientist Dr. Joseph Nuth, who does research for the Goddard Space Flight Center, noted that humanity was ill-prepared to defend itself against a surprise asteroid or comet.
“The biggest problem, basically, is there’s not a hell of a lot we can do about it at the moment.”
“But on the other hand they are the extinction-level events, things like dinosaur killers, they’re 50 to 60 million years apart, essentially. You could say, of course, we’re due, but it’s a random course at that point." says Dr. Nuth.
And then there is the problem of Earth’s general lack of preparedness against a potential impactor — a killer asteroid, as it were.
He draws attention to a comet that passed nearby Mars in 2014.
So what is the solution?
He sounds like he has thoroughly thought about it.
