The precept right here is far the identical, with the railguns behaving considerably like discretized variations of thrusters, offering instantaneous changes in velocity versus sustained regular change. Drawbacks: as above, the momentum change you get is minuscule because it's important to subtract off the 11km/s wanted to launch the material upwards ceaselessly in any respect. Solar sail technique. I can not truthfully add much to that article besides to say that to move the Earth substantially, the sail used is going to need to be fairly massive. You might construct an engine at both pole and this would not have any impact, however wherever else and the continuously changing angle of thrust will trigger the Earth to behave somewhat like a loose Catherine Wheel-sort firework. It entails asteroids, like the above technique, only as an alternative of direct impacts, this time we simply steer them past the Earth, allowing rock and planet to alternate a bit of momentum, with the results of an Earth moving on a barely completely different track and an asteroid moving on a considerably completely different one.

Rather than simply bouncing off, the item destroyed much of both itself and Earth, inflicting an unlimited spray of matter to be hurled off from the influence point; this matter coagulated into what's now the Moon. Certainly, no single affect goes to do all of the course altering you will be wanting to tug off. And lastly, suppose that all of them jumped at exactly the same instant, which in fact they will not, seeing because the time distinction between the fastest watch and the slowest will doubtless be over 5 minutes. Suppose they had been all at the very same point on Earth (which they will not be, thus mitigating the consequences of the jump). 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're seemingly to seek out - there are heavier moons and complete planets you might think about using, however to be honest from this perspective it seems more like utilizing a succession of lots of, 1000's or tens of thousands of smaller asteroid impacts could be a better wager. Basically, the point here is that modelling impacts like these is a tricky enterprise. Suppose everybody on the planet weighed 100kg (which is an overestimate, 70kg is more prefer it, most likely much less).

Jumping up and all the way down to attempt to move the Earth is like mounting a fan on a sailboat, pointing the fan at the sail, and expecting the boat to maneuver forwards. Way right down to 1021 tonnes. You may reuse the identical asteroid time and again, what is billiards looping it around just a few gasoline giants and back to realize heaps more kinetic energy from these fuel giants in the same manner that Earth just gained velocity from the rock. Getting everyone in the world to leap at the same time. Which means the distance the Earth moves when everybody jumps will be one trillionth of the space that all the folks jumped: that is to say, 10-eleven metres, or about half the radius of a hydrogen atom. Since the Sun carries the overwhelming majority of the whole mass of the solar system, any drive which moves it is likely to drag all the planets along with it.

Moving the Sun is about 6 orders of magnitude harder than transferring the Earth but the Sun is repeatedly emitting energy which may be productively harnessed for this purpose. Suppose that all of them jumped ten metres in the air (an enormous overestimate, fifty centimetres is more possible and possibly a lot much less). This may be employed to move the Sun and Earth in tandem to a place where the Earth can more easily be destroyed. Gravity assistance. This is a technique originally proposed as a technique of transferring Earth to the next orbit around the Sun so as to put it aside from the Sun's inevitable Red Giant growth. It is feasible to use a solar sail to steer the Earth into the Sun. Construct a huge photo voltaic sail with a significant mass. Wait long sufficient, and the photo voltaic wind blowing the sail outwards will take the Earth outward too, since the 2 are gravitationally bound together! Plan it right, and you can couple it together with the Earth with gravity alone, using the solar wind to balance out the Earth's gravitational attraction. The main problem here is determining how to pick up large pieces of continental plate with out breaking them.
