And once again, by your proposed model to fund science. How are we even going to know there's a comet hurling towards earth ? Gazing out there for neat stuff in the cosmos isn't even a problem in the first place, so it's completely useless by your metric.

>>move the comet out of the way, or destroy it, or in the worst case, prepare an "ark" so that humans can survive"

You make some highly unorthodox points. There's nothing wrong with that in itself; in fact, it's welcomed. But when people respond to those points and indicate they have no merit (like how research scientists are in it for their own enrichment), being rude and dismissive is not going to convince anyone you're right; quite the contrary.
