It’s like Carl Sagan has returned in the form of a bald man armed with a laser!
How do we stop an asteroid, one that might impact the Earth in 2036? Boom and tug. Push it a little with a nuke, and then tow it with a satellite a little more, to insure it doesn’t just return the same way in the future.
But, really, watch the episode for the explosions! And, make your wife watch, because it’s really boring for woman to watch guys blowing things up!
