Bla bla bla bla. Chances of a big enough asteroid hitting Earth are next to nil. The outer big planets are magnetic walls that change the course of most incoming objects away from Earth. The asteroid belt makes rocks coming from outside the solar system shoot off in like flippers on a pinball machine.
The only threats are outside the solar system, they may be on an intercept course for Earth. But the big gravity wells in our solar system change that when they get close enough.
Uh... there’s tons of old, giant craters all over earth. I’m pretty sure those planets were around then as well.
Also, check the Cheyablinsk(sp?) meteor from last year.
I'd say the chances are 100% it will get hit sometime in the next billion years.
You really haven't thought the physics of this situation through all the way, have you?
You don’t do science much do you?
The chances of an asteroid strike is close to a certainty given a large enough time line. Your idea of the “magnetic wall” and the asteroid belt is hysterical.
Look up at the moon some time. That will give you a clue.
Earth would look JUST LKE it, if we didn’t have weather and techtonic plate activity.
So, what you’re saying is that, the planets in our solar system help protect the earth from huge asteroids and meteors. Sounds like a very intelligent way to design a universe. :)
And most assuredly these gravity wells always sling the incoming objects away from earth......not.
