The main problem right here is figuring out how to select up big pieces of continental plate without breaking them. The obvious major disadvantage with this methodology is that right now there aren't even theories as to how you would probably build rocket engines of the kind proposed right here. Gravity assistance. This is a method originally proposed as a means of shifting Earth to the next orbit across the Sun in an effort to reserve it from the Sun's inevitable Red Giant growth. If there was some approach to electrically cost the Earth, by dumping numerous identically charged particles onto the Earth or just ionizing particles already on Earth - a big amber rod might perhaps be in order - then we could use magnetic fields to drive the planet within the direction we needed it to go. Just use it to tack against the route in which the Earth is travelling, steadily slowing its orbital velocity and rising the orbit's eccentricity, till the orbit passes inside the Roche restrict the place the Earth is torn apart by tidal forces. With half of the Sun's radiation blocked/mirrored in the opposite path, the Sun now has a web thrust upwards (i.e. within the path of the "hat").

You may construct an engine at either pole and this would not have any impact, however wherever else and the always altering angle of thrust will trigger the Earth to behave considerably like a unfastened Catherine Wheel-type firework. Note that the Earth doesn't and is not going to behave like a stable, inflexible billiard ball under such big impacts as these. Basically, the purpose right here is that modelling impacts like these is a tricky enterprise. Ceres, the photo voltaic system's largest asteroid, has less than 1/40,000th the mass of Earth; the Moon, a mere 1/80th. These objects are the heaviest you are possible to search out - there are heavier moons and total planets you may consider using, but to be sincere from this standpoint it seems to be more like utilizing a succession of lots of, hundreds or tens of thousands of smaller asteroid impacts would be a greater guess. Suppose that there were ten billion individuals (one other overestimate - there are about 6.4 billion on the time of writing).

Suppose that they all jumped ten metres in the air (a huge overestimate, fifty centimetres is extra probably and doubtless a lot much less). Altogether that's a mass of 1 billion tonnes of humanity jumping ten metres within the air. Jumping up and down to try to maneuver the Earth is like mounting a fan on a sailboat, pointing the fan at the sail, and anticipating the boat to maneuver forwards. Way all the way down to 1021 tonnes. You could reuse the same asteroid repeatedly, looping it round a couple of gas giants and again to achieve tons extra kinetic power from those fuel giants in the identical method that Earth just gained velocity from the rock. It entails asteroids, like the above technique, only as a substitute of direct impacts, this time we simply steer them previous the Earth, permitting rock and planet to exchange a bit of momentum, with the results of an Earth transferring on a barely completely different monitor and an asteroid moving on a considerably completely different one. Which means the space the Earth strikes when everybody jumps will probably be one trillionth of the space that all of the individuals jumped: that's to say, 10-eleven metres, or about half the radius of a hydrogen atom.

Better, you may use many, many asteroids one after the other in a gentle stream, and reduce down the full time significantly. The Earth may be very massive, shifting very quick, and subsequently very troublesome to cease and even slow down. Maybe you need to destroy it: a significant number of strategies for destroying the Earth involve moving it by some substantial quantity. It gets better. Even assuming the Earth did move by some important distance when all people jumped, simply give it some thought: it'd transfer right back once more! Maybe. Or higher but: the Earth already has a standing magnetic area; maybe we may assemble a cylinder of cable around it, and go current to move it utilizing Lorentz forces. Construct a huge solar sail with a big mass. Solar sail methodology. I am unable to honestly add a lot to that article except to say that to maneuver the Earth considerably, the sail used is going to have to be fairly large.
