Altogether that's a mass of 1 billion tonnes of humanity jumping ten metres within the air. Suppose that all of them jumped ten metres in the air (a huge overestimate, fifty centimetres is extra seemingly and doubtless much less). Solar sail technique. I am unable to honestly add much to that article except to say that to maneuver the Earth considerably, the sail used is going to must be fairly massive. Electromagnetic influence. Traditionally the Earth is thought of as "floor", "impartial". Belgium. Design them rigorously so that when used the rocket engines do not truly just propel themselves through the bottom and into Earth where they become ineffective - you could have to periodically dig them out once more after a number of thousand years' continued thrusting, or else simply build new ones over the top. Wait long sufficient, and the photo voltaic wind blowing the sail outwards will take the Earth outward too, since the 2 are gravitationally sure collectively! You possibly can construct an engine at either pole and this wouldn't have any impact, but anyplace else and the consistently changing angle of thrust will cause the Earth to behave somewhat like a unfastened Catherine Wheel-type firework. You bounce up, the Earth goes down: you fall down, the Earth comes up to satisfy you.

Suppose they were all at the exact same level on Earth (which they will not be, thus mitigating the results of the jump). It all relies upon how fussy you're about how the Earth appears afterwards, after all. Certainly, no single affect is going to do all of the course changing you'll be wanting to drag off. Rather than simply bouncing off, the thing destroyed a lot of both itself and Earth, causing an unlimited spray of matter to be hurled off from the affect level; this matter coagulated into what is now the Moon. The principle here is much the same, with the railguns behaving somewhat like discretized versions of thrusters, providing instantaneous changes in velocity versus sustained regular change. 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 entire planets you could possibly consider using, but to be honest from this standpoint it seems extra like using a succession of a whole lot, thousands or tens of hundreds of smaller asteroid impacts could be a better wager. Another, extra refined, downside is that the Earth is consistently spinning.

Which implies the distance the Earth moves when everybody jumps shall be one trillionth of the gap that all the individuals jumped: that is to say, 10-eleven metres, or about half the radius of a hydrogen atom. And lastly, suppose that all of them jumped at precisely the same on the spot, which after all they won't, seeing because the time difference between the fastest watch and the slowest will possible be over five minutes. Note that the Earth does not and will not behave like a strong, rigid billiard ball beneath such large impacts as these. This can be employed to move the Sun and Earth in tandem to a spot the place the Earth can extra simply be destroyed. You may reuse the same asteroid repeatedly, looping it round just a few gasoline giants and back to gain lots extra kinetic energy from those fuel giants in the identical manner that Earth just gained velocity from the rock. 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 try 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. The Earth could be very huge, shifting very fast, and therefore very difficult to cease and even slow down. The obvious major downside with this methodology is that right now there aren't even theories as to how you would probably construct rocket engines of the type proposed here. Direct rocket propulsion. Build gigantic, possibly nuclear upward-pointing rocket furnaces, possibly one, maybe 4, perhaps a million, whatever you may price range for. However, pool particularly refers to a game performed on a pool table. In its original use, billiards refers to any kind of cue sport, together with carom billiards, pool, and snooker. Billiards methodology. Clonk the Earth with something large and heavy, causing it to change course. Maybe Earth is about to hit an asteroid. Alternatively, as the Earth's angular kinetic energy is negligible compared to its orbital kinetic energy, you might consider diverting a comparatively small amount of resources to simply stopping the Earth from spinning at all, earlier than starting the principle mission.
