The principle right here is way the identical, with the railguns behaving considerably like discretized variations of thrusters, offering instantaneous adjustments in velocity as opposed to sustained regular change. Drawbacks: as above, the momentum change you get is minuscule as a result of it's a must to subtract off the 11km/s needed to launch the material upwards perpetually in any respect. Solar sail methodology. I can't truthfully add much to that article besides to say that to maneuver the Earth substantially, the sail used goes to must be fairly large. You could possibly build an engine at either pole and this wouldn't have any impact, however wherever else and the always changing angle of thrust will cause the Earth to behave considerably like a loose Catherine Wheel-type firework. It involves asteroids, like the above methodology, only as a substitute of direct impacts, this time we just steer them past the Earth, permitting rock and planet to change somewhat momentum, with the result of an Earth shifting on a barely completely different monitor and an asteroid transferring on a significantly totally different one.

Rather than merely bouncing off, the item destroyed much of each itself and Earth, inflicting an unlimited spray of matter to be hurled off from the affect level; this matter coagulated into what's now the Moon. Certainly, no single affect is going to do all of the course changing you may be wanting to pull off. And lastly, suppose that all of them jumped at exactly the same instantaneous, which after all they will not, seeing because the time distinction between the quickest watch and the slowest will likely be over 5 minutes. Suppose they had been all at the exact same level on Earth (which they will not be, thus mitigating the effects of the bounce). Ceres, the photo voltaic system's largest asteroid, has lower than 1/40,000th the mass of Earth; the Moon, a mere 1/80th. These objects are the heaviest you are likely to seek out - there are heavier moons and entire planets you possibly can consider using, however to be trustworthy from this standpoint it seems more like utilizing a succession of a whole bunch, hundreds or tens of 1000's of smaller asteroid impacts could be a better guess. Basically, the purpose here is that modelling impacts like these is a difficult enterprise. Suppose everyone on the planet weighed 100kg (which is an overestimate, 70kg is more prefer it, most likely less).

Jumping up and down to try to maneuver the Earth is like mounting a fan on a sailboat, pointing the fan on the sail, and expecting the boat to maneuver forwards. Way right down to 1021 tonnes. You may reuse the same asteroid time and again, what is billiards looping it around just a few gas giants and again to gain lots extra kinetic vitality from these fuel giants in the identical manner that Earth simply gained velocity from the rock. Getting everyone on the planet to leap at the identical time. Which suggests the distance the Earth strikes when everybody jumps shall be one trillionth of the distance that all of the individuals jumped: that is to say, 10-11 metres, or about half the radius of a hydrogen atom. Since the Sun carries the overwhelming majority of your complete mass of the solar system, any force which moves it is prone to drag all the planets together with it.

Moving the Sun is about 6 orders of magnitude tougher than transferring the Earth but the Sun is constantly emitting power which will be productively harnessed for this objective. Suppose that all of them jumped ten metres in the air (an enormous overestimate, fifty centimetres is extra probably and probably a lot less). This can be employed to maneuver the Sun and Earth in tandem to a spot the place the Earth can extra easily be destroyed. Gravity help. This is a technique originally proposed as a means of shifting Earth to a better orbit around the Sun in order to save it from the Sun's inevitable Red Giant enlargement. It is possible to make use of a solar sail to steer the Earth into the Sun. Construct a huge photo voltaic sail with a major mass. Wait long sufficient, and the photo voltaic wind blowing the sail outwards will take the Earth outward too, since the 2 are gravitationally sure together! Plan it right, and you can couple it together with the Earth with gravity alone, using the solar wind to steadiness out the Earth's gravitational attraction. The main downside right here is figuring out how to pick up big items of continental plate with out breaking them.
