The precept here is way the same, with the railguns behaving somewhat like discretized variations of thrusters, providing instantaneous changes in velocity versus sustained steady 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 eternally in any respect. Solar sail methodology. I am unable to honestly add much to that article besides to say that to maneuver the Earth substantially, the sail used goes to should be pretty massive. You could construct an engine at either pole and this wouldn't have any effect, however anywhere else and the constantly changing angle of thrust will cause the Earth to behave somewhat like a loose Catherine Wheel-kind firework. It involves asteroids, just like the above method, only instead 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 track and an asteroid shifting on a considerably completely different one.

Rather than merely bouncing off, the object destroyed a lot of each itself and Earth, inflicting a vast spray of matter to be hurled off from the affect point; this matter coagulated into what is now the Moon. Certainly, no single affect goes to do all of the course changing you'll be wanting to tug off. And lastly, suppose that they all jumped at exactly the identical instant, which after all they won't, seeing because the time distinction between the quickest watch and the slowest will seemingly be over 5 minutes. Suppose they were all at the exact same level on Earth (which they won't be, thus mitigating the results of the leap). 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 possible to search out - there are heavier moons and whole planets you would consider using, however to be honest from this perspective it appears more like using a succession of a whole lot, thousands or tens of thousands of smaller asteroid impacts would be a better bet. Basically, the purpose right here is that modelling impacts like these is a tough enterprise. Suppose everyone on the planet weighed 100kg (which is an overestimate, 70kg is more like it, in all probability much less).

Jumping up and down to attempt to move the Earth is like mounting a fan on a sailboat, pointing the fan on the sail, and expecting the boat to maneuver forwards. Way down to 1021 tonnes. You might reuse the same asteroid again and again, what is billiards looping it round just a few fuel giants and again to achieve heaps extra kinetic vitality from these gas giants in the same method that Earth simply gained velocity from the rock. Getting everybody on the planet to jump at the identical time. Which implies the gap the Earth strikes when everyone jumps will be one trillionth of the space that all the individuals jumped: that is to say, 10-11 metres, or about half the radius of a hydrogen atom. For the reason that Sun carries the vast majority of the whole mass of the photo voltaic system, any power which strikes it's prone to drag all the planets together with it.

Moving the Sun is about 6 orders of magnitude harder than transferring the Earth but the Sun is repeatedly emitting power which will be productively harnessed for this function. Suppose that they all jumped ten metres in the air (a huge overestimate, fifty centimetres is more probably and probably much much less). This can be employed to maneuver the Sun and Earth in tandem to a place where the Earth can more simply be destroyed. Gravity help. This is a method initially proposed as a technique of shifting Earth to the next orbit across the Sun with the intention to save it from the Sun's inevitable Red Giant enlargement. It is possible to use a photo voltaic sail to steer the Earth into the Sun. Construct a huge solar sail with a big mass. Wait long enough, and the solar wind blowing the sail outwards will take the Earth outward too, since the 2 are gravitationally certain collectively! Plan it right, and you'll couple it together with the Earth with gravity alone, using the photo voltaic wind to balance out the Earth's gravitational attraction. The key drawback right here is figuring out how to select up huge pieces of continental plate with out breaking them.
