Asteroid Solutions
Sometimes I think when will a asteroid hit us? What if it could wipe out humanity? There are solutions but I want more solutions, solutions that could save us. What do you think?
Anything that explodes the asteroid isn't too helpful because there will just be smaller meteors of almost the same volume. Maybe we send missiles at the asteroid but the missiles would stick to the asteroid and then would slow down the meteor then the meteor would go backwards and away from earth. However, this solution would need to be done years before the collision. Anything that explodes the asteroid isn't too helpful because there will just be smaller meteors of almost the same volume.

The most realistic notion is to deflect it.

I see that but with what? I think we put something like a giant trampoline in front of it though the meteor is hurtling towards Earth at very fast speeds. Maybe somethings stronger.

Asteroids burn up and break apart into incredibly small pieces when hurling towards the Earth, so the only time Asteroids strikes actually do manage to come crashing down are really large ones. So we would need an asteroid of the moon to do any real damage to the Earth. But as for a contingency plan, blowing it up into smaller pieces to do less damage is the the best current method.

There are many ways of doing it. Nuclear weapons could blow it up, but that would only work with asteroids of a certain consistency. Most asteroid and comets however would just split into more pieces and do more damage. But there is no way to know (right now anyways) how the asteroid is made, or what it's made of. So doing this in the hopes that it's one of the 1% of all space-rocks that it would work on is this asteroid is just stupid.
We could explode the nuclear weapons near them, to push them off track. To get a little more science fiction, you can use a space-laser to push it, or a giant mirror focusing the sun´s light into a powerful beam (like burning an ant.) You could even just smash a satellite into it, if you have enough time it would push it off track over the course of many many years to where Earth is in no danger. Quote:
Exploding them near the asteroid will push it off track, while not actually affecting the asteroid directly. Quote:
That is absolutely false. If something the size of the moon hit Earth, all life would be extinct. Nothing would survive. The entire crust of the Earth would become molten again. The asteroid that killed the dinosaurs (and around 70% of all other life on Earth) was only 6.2 miles in diameter. The moon is 2159.1 miles in diameter. A little over a fourth of the size of Earth. The asteroid impact itself doesn't affect the entire Earth. However, it does change the composition of the atmosphere greatly which life can't adapt to over-night, and that composition change also includes blocking out the sun for months killing most plants. Without plants, herbivores die, when herbivores die, there are substantially less food for carnivores so they tend to starve. The acidity and oxygen levels of the ocean (and other fresh-water bodies of water) also change, killing off many species in the water. And for the love of god, don't say "WELL THAT'S JUST A THEORY" because I will probably have to punch you. It's a theory because we know what will happen (what I just said) if an asteroid that size hit Earth. We also have the crater, minerals not from Earth that magically appeared in the area of the crater, geographic evidence, and so on. |

An asteroid bigger than 10 meters in diameter would explode with more force than an atomic bomb (see Tunguska event). So if you split a 5 kilometer asteroid into 100 pieces, instead of having one huge supertsunami and every forest on Earth being razed and in flames, you'll have hundreds of very large tsunamis and practically everything being obliterated. The best way to confront an asteroid threat is to gently push it away, using either a solar sail, a nuclear propelled rocket, or some other unknown method. Thankfully we don't have to think about such an event for hundreds of years at least (Apophis only has a minute chance of collision in 2038, and even then it would just be devastating, not catastrophic). |
