That naturally depends on what the "threat" is. Take an asteroid or comet. Comets are by their nature what are referred to as "long period
objects". They come in to our part of the inner solar system at a sharp angle to the ecliptic, meaning we don't see them until they are very close.
Moving at tens of miles per second a "small" object like a comet with a nucleus only a few hundred meters across has more kinetic energy by about
ten orders of magnitude then all the nuclear weapons ever built. No matter where it hits, it ain't gonna be pretty. Any object of a size and with the
kinetic energy to "erase us" is unfortunately likely by simple odds to hit the pacific or atlantic oceans. You don't need to be big, if you are
fast enough an object no bigger then a small office block hitting with such speed as a comet, will be the same as if a mountain range was "dropped"
in the ocean. The good news if your within 100-500kilometers, the thermal effects will vaporize and/or particleize you. For a brief moment you won't
be able to breath and then its over. If your asleep you all know that song that says thats the best way to die? If I did live and die before, I don't
remember. Sorry. Anyway you look at it the effect would be "Biblical"
They have calculated an object with enough "juice" will raise a tidal wave that is over 12,000 meters high. But that presents certain fundamental
problems. Above 3,000 meters (roughly 10,000 feet) the air pressure quickly drops. And that rate a large portion of the ocean water will flash into
vapor. All that transferred energy has to go somewhere. That might increase the pressure on the Earth's surface tremendously. One way or the other
enough energy transferred, and lets say there is no way to describe it. We believe the possible death of the Clovis people in North America about
13,000 years ago, keep in mind these people inhabit an area that at the time was experiencing the the full melt at the end of the last ice age. And
they occupied an area from what is now the central and near northern American plains (Canada was still under considerable ice) to the southern most
part of the present continental United States. They built huge pyramid like mounds in what is now Missouri, very close to what was built in
pre-historic Britain. Long before Stonehenge.
There is evidence of an asteroid, in astronomical parlance referred to as a boloid, or "grainy asteroid", as opposed to a solid iron mass exploded
over North America around this time. Both it's energy release and "scattered pattern" would have bean like a gigantic shot gun shell exploding over
its target. It never reached the ground, as may have been the case with the Tunguska Incident of 1908. If that object in 1908 had hit a few hours
sooner, it would have vaporized London. No doubt our entire religious mythology would have been rewritten that very day. Just imagine the headlines at
that time the British Empire was the most powerful state the world had ever known. The Roman Empire in its day thought they ruled the world, they just
didn't know how big it really was. They "missed" China, OOP's. At that time in history military power was determined by the power of a nations
navy. And the British ran righted over the entire Earth. Until Hitler was stupid enough to declare war on my country after Pearl Harbor was attacked,
and power of the American economy that laid waste not just to his empire but the Japanese as well. We barley worked up a sweat. But we learned and
tasted power. An intense narcotic.
But what if something happened in the coming year that is the opposite of apocalyptic? Lets face it gang, if the Sun farts a big one a major solar
flare that hits us at the wrong time? We will be lucky if we only loose all our satellites (and that means GPS, the Internet, cell phones, and our
VELA early warning detection system designed to spot missile plumes rising above the Earth...) If we are lucky we will keep the lower band millimeter
wave radar systems intact, but anything with a solid state circuit is likely to be fried. And all current radars use solid state electronics. As with
the Cuban missile crises and the 1973 Yom Kipper war we came oh so close. By then (1973) Nixon was near the end of Watergate and frequently drunk.
No, you don't want to know the details.
What if it was "understood" that we as an intelligent species were not alone. Good gracious, hardly. If nothing else happens the internet will
connect the entire human race with each other with in twenty five years. Technology is not blame for the lag time but politics is. But in time if we
survive long enough as a race, no government on Earth will be able to stop the inevitable. And that scars dictators to death. It will be what will be.
Embrace the unknown. We don't have much of a choice now but to win over hate. Never give up.
