The principle right here is far the same, with the railguns behaving somewhat like discretized versions of thrusters, providing instantaneous changes in velocity as opposed to sustained regular change. Drawbacks: as above, the momentum change you get is minuscule because you have to subtract off the 11km/s needed to launch the material upwards perpetually in any respect. Solar sail methodology. I can not honestly add much to that article besides to say that to move the Earth considerably, the sail used goes to should be fairly big. You could build an engine at either pole and this wouldn't have any effect, however anyplace else and the continually changing angle of thrust will trigger the Earth to behave somewhat like a loose Catherine Wheel-type firework. It entails asteroids, like the above methodology, solely instead of direct impacts, this time we just steer them past the Earth, allowing rock and planet to exchange a little bit momentum, with the result of an Earth shifting on a slightly different monitor and an asteroid shifting on a significantly completely different one.

Rather than merely bouncing off, the article destroyed a lot of each itself and Earth, inflicting an enormous spray of matter to be hurled off from the impression level; this matter coagulated into what is now the Moon. Certainly, no single impression goes to do all the course altering you will be wanting to drag off. And lastly, suppose that all of them jumped at exactly the identical immediate, which of course they will not, seeing because the time difference between the quickest watch and the slowest will probably be over five minutes. Suppose they have been all at the exact same point on Earth (which they will not be, thus mitigating the effects of the bounce). Ceres, the solar 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 probably to find - there are heavier moons and whole planets you could consider using, but to be sincere from this point of view it appears more like using a succession of a whole bunch, hundreds or tens of 1000's of smaller asteroid impacts would be a better wager. Basically, the purpose right here is that modelling impacts like these is a tricky enterprise. Suppose everyone on the planet weighed 100kg (which is an overestimate, 70kg is more like it, most likely less).

Jumping up and down to attempt 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 might reuse the same asteroid many times, what is billiards looping it around a couple of gasoline giants and again to achieve lots extra kinetic energy from those gas giants in the identical approach that Earth simply gained velocity from the rock. Getting all people in the world to jump at the same time. Which implies the gap the Earth moves when everyone jumps will likely be one trillionth of the space that all of the folks jumped: that is to say, 10-eleven metres, or about half the radius of a hydrogen atom. For the reason that Sun carries the overwhelming majority of the whole mass of the photo voltaic system, any force which moves it's prone to drag all of the planets along with it.

Moving the Sun is about 6 orders of magnitude more difficult than shifting the Earth however the Sun is constantly emitting energy which might be productively harnessed for this function. Suppose that they all jumped ten metres within the air (a huge overestimate, fifty centimetres is more seemingly and possibly much less). This may be employed to maneuver the Sun and Earth in tandem to a place where the Earth can more easily be destroyed. Gravity assistance. This is a method initially proposed as a means of moving Earth to a higher orbit around the Sun with a purpose to save it from the Sun's inevitable Red Giant expansion. It is feasible to make use of a photo voltaic sail to steer the Earth into the Sun. Construct a huge photo voltaic sail with a major mass. Wait long enough, and the solar wind blowing the sail outwards will take the Earth outward too, since the 2 are gravitationally sure together! Plan it proper, and you'll couple it together with the Earth with gravity alone, using the solar wind to balance out the Earth's gravitational attraction. The most important downside right here is determining how to pick up big items of continental plate without breaking them.
