It's probably a lot worse than they are letting on. Probably the end of humanity, they're scrambling, but keeping it quiet to avoid chaos. Nice knowing ya'll

Originally posted by Landrover View PostI saw a few news reports on it. Some folks were concerned, some were saying it made sense. So, I checked to see what astro-physicist Neil deGrasse Tyson said about it. He broke it down for us far less knowledgeable cavemen ..............and it works for me! Way more upside. That is how science works, experimentation! We deaux know that dinosaur's became extinct by a huge asteroid strike, thus why take the chance when we can at least be prepared if it became a issue to mankind.

I would love to see their mathematical models on this and their probability distribution on how much they think they can “move” an astroid based on different size astroids.

The asteroid that caused the extinction of the dinosaurs was estimated to be 57-8 miles wide traveling 30k mph. Do you think a rocket that burned most of it propellant to escape the atmosphere would have enough weight left to cause any movement. It’s like shooting a BB gun at a tank.
Show me what a rocket can apply to an asteroid before it hits terminal zone and how big of asteroid that amount of force can move.

What is the largest size astroid you think we CAN successfully deviate? How much damage would that astroid do if it impacted earth?

Asteroid - 530-foot
Impact Velocity -15,000 mph
Impactor mass - 610 kg (1,340 lb),
Impact - 500 kg (1,100 lb)
Velocity change of asteroid expected- 0.4 mm/s
Guess we will see next September if their calculation was accurate.

If we were able to hit an asteroid a few million miles away, it wouldn’t have to move it much at all to dramatically change the outcome here. So if you could change the trajectory by a fraction, of a fraction of a degree then that could be the difference between a direct hit vs an air burst vs skipping off of the atmosphere.
The same could be done with either speeding up an asteroid or slowing it down. If it is done soon enough, the gravitational pull from other planets could alter the trajectory by decreasing or increasing the time planet’s gravitational pull have to effect the asteroid.
There are thousands of variables which makes predicting what is going to happen VERY difficult.

Isn't there a Gerard Butler movie about asteroids hitting earth? Greenland or something like that.
In that movie everyone is under the impression the asteroid is gonna miss earth until it's too late... meanwhile all the governments knew the truth all along.
