The most obvious major downside with this method is that proper now there aren't even theories as to how you can presumably build rocket engines of the type proposed here. Direct rocket propulsion. Build gigantic, possibly nuclear upward-pointing rocket furnaces, maybe one, perhaps 4, perhaps one million, no matter you possibly can finances for. This may be employed to maneuver the Sun and Earth in tandem to a spot where the Earth can extra easily be destroyed. Gravity help. This is a method initially proposed as a technique of moving Earth to the next orbit around the Sun to be able to reserve it from the Sun's inevitable Red Giant expansion. Plan it right, and you can couple it along with the Earth with gravity alone, using the photo voltaic wind to steadiness out the Earth's gravitational attraction. Belgium. Design them rigorously in order that when used the rocket engines do not actually simply propel themselves through the bottom and into Earth where they grow to be ineffective - you may must periodically dig them out once more after a number of thousand years' continued thrusting, or else just construct new ones over the top. The key downside here is determining how to pick up huge items of continental plate without breaking them.

Another, extra subtle, problem is that the Earth is continually spinning. Alternatively, as the Earth's angular kinetic vitality is negligible compared to its orbital kinetic vitality, you might consider diverting a relatively small quantity of assets to simply stopping the Earth from spinning at all, before starting the principle venture. You would reuse the identical asteroid again and again, looping it round a few gas giants and again to achieve tons more kinetic energy from those fuel giants in the identical way that Earth just gained velocity from the rock. Suppose that all of them jumped ten metres in the air (a huge overestimate, fifty centimetres is extra possible and doubtless much less). And lastly, suppose that they all jumped at exactly the same on the spot, which of course they won't, seeing as the time difference between the fastest watch and the slowest will possible be over 5 minutes. Wait lengthy enough, and the photo voltaic wind blowing the sail outwards will take the Earth outward too, since the two are gravitationally bound together! Moving the Sun is about 6 orders of magnitude tougher than moving the Earth but the Sun is constantly emitting energy which can be productively harnessed for this purpose.

Since the Sun carries the overwhelming majority of all the mass of the photo voltaic system, any drive which strikes it is more likely to drag the entire planets together with it. Altogether that's a mass of one billion tonnes of humanity leaping ten metres in the air. Way right down to 1021 tonnes. If there was some strategy to electrically cost the Earth, by dumping lots of identically charged particles onto the Earth or just ionizing particles already on Earth - a big amber rod would possibly maybe be in order - then we could use magnetic fields to drive the planet within the path we wanted it to go. Suppose everyone on the planet weighed 100kg (which is an overestimate, 70kg is extra prefer it, probably less). It entails asteroids, like the above technique, solely as an alternative of direct impacts, this time we just steer them previous the Earth, allowing rock and planet to change a little bit momentum, with the result of an Earth transferring on a barely different observe and an asteroid shifting on a considerably completely different one. It is possible to use a solar sail to steer the Earth into the Sun. With half of the Sun's radiation blocked/mirrored in the alternative direction, what is billiards the Sun now has a internet thrust upwards (i.e. in the direction of the "hat").

If balanced correctly, the "hat" neither falls into the Sun nor is blown away. Build an infinite lightweight "hat" for the Sun, which catches the Sun's rays. You might construct an engine at either pole and this would not have any effect, however wherever else and the continuously altering angle of thrust will cause the Earth to behave somewhat like a free Catherine Wheel-type firework. Which suggests the space the Earth moves when all people jumps can be one trillionth of the distance that all the folks jumped: that's to say, 10-eleven metres, or about half the radius of a hydrogen atom. Note that the Earth does not and is not going to behave like a stable, inflexible billiard ball beneath such enormous impacts as these. Basically, the purpose right here is that modelling impacts like these is a tough enterprise. 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're possible to seek out - there are heavier moons and whole planets you could consider using, but to be sincere from this perspective it appears to be like extra like utilizing a succession of hundreds, hundreds or tens of 1000's of smaller asteroid impacts could be a better guess.
