10 Most-Terrifying Space Weapons

1. Re-Directing An Orbiting Asteroid To Smash Into Earth

Huge balls of rock flying across the galaxy at more than 280,000miles-per-hour, asteroids are not something that anyone wants to see colliding into the Earth.

If they ever did then the outcome would be catastrophic - the sea-levels would rise and flood the land, temperatures would plummet or rocket, and Earth could even be knocked out of its current orbit with the Sun, making the planet uninhabitable.

Essentially an asteroid landing on the surface of the Earth would bring about the Apocalypse - yet in Soviet circles during the Cold War the idea of re-directing one towards the USA was discussed. Yes, the USSR contemplated how theoretically possible it would be to manipulate the orbit of an asteroid and then have it come crashing down to Earth.

Thankfully it was quickly dismissed as being close to impossible given the technology at the time and the proposal was shelled. Otherwise we probably wouldn't be around today...
