Gravity help. This is a method initially proposed as a means of shifting Earth to a better orbit around the Sun with a purpose to save it from the Sun's inevitable Red Giant enlargement. Which means the gap the Earth strikes when everybody jumps will be one trillionth of the space that all the folks jumped: that's to say, 10-eleven metres, or about half the radius of a hydrogen atom. Because the Sun carries the vast majority of your entire mass of the solar system, any drive which moves it's more likely to drag all of the planets together with it. It's because total it carries almost exactly zero overall cost. If there was some technique to electrically cost the Earth, by dumping a number of identically charged particles onto the Earth or just ionizing particles already on Earth - a big amber rod might perhaps be in order - then we may use magnetic fields to drive the planet within the course we wished it to go. Alternatively, as the Earth's angular kinetic energy is negligible in comparison with its orbital kinetic vitality, you would possibly consider diverting a relatively small amount of assets to simply stopping the Earth from spinning at all, before beginning the main challenge.

You by no means know while you might need to considerably alter the orbital path of the Earth. Maybe it isn't, but you need it to. Maybe you wish to destroy it: a big variety of strategies for destroying the Earth involve shifting it by some substantial amount. It gets higher. Even assuming the Earth did move by some vital distance when everyone jumped, simply give it some thought: it'd transfer right back again! Suppose everybody on the planet weighed 100kg (which is an overestimate, 70kg is extra like it, in all probability less). Getting everyone on the planet to leap at the same time. Suppose they have been all at the exact same level on Earth (which they will not be, thus mitigating the effects of the soar). You jump up, the Earth goes down: you fall down, the Earth comes up to fulfill you. Just use it to tack towards the direction through which the Earth is travelling, progressively slowing its orbital velocity and growing the orbit's eccentricity, till the orbit passes inside the Roche limit the place the Earth is torn apart by tidal forces.

The precept right here is much the same, with the railguns behaving considerably like discretized versions of thrusters, offering instantaneous adjustments in velocity versus sustained regular change. Better, you possibly can use many, many asteroids one after the other in a gradual stream, and lower down the whole time significantly. Way all the way down to 1021 tonnes. Altogether that is a mass of one billion tonnes of humanity leaping ten metres within the air. That's a trillion occasions heavier than all of humanity. You could repeat this thousands of instances over the course of millions of years. This ends in a minute theoretical acceleration but over tens of millions of years the velocity would accumulate to one thing substantial. Belgium. Design them fastidiously in order that when used the rocket engines don't actually just propel themselves by the bottom and into Earth where they change into useless - you may have to periodically dig them out once more after several thousand years' continued thrusting, or else just construct new ones over the top. The most obvious main disadvantage with this method is that right now there aren't even theories as to how you may possibly build rocket engines of the kind proposed right here. Rather than simply bouncing off, the thing destroyed much of both itself and Earth, inflicting a vast spray of matter to be hurled off from the influence point; this matter coagulated into what is now the Moon.

With half of the Sun's radiation blocked/mirrored in the opposite route, the Sun now has a net thrust upwards (i.e. in the direction of the "hat"). This can be employed to move the Sun and Earth in tandem to a spot where the Earth can extra easily be destroyed. Suppose that they all jumped ten metres in the air (an enormous overestimate, fifty centimetres is extra possible and doubtless a lot less). Suppose that there have been ten billion individuals (another overestimate - there are about 6.4 billion on the time of writing). 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 find - there are heavier moons and entire planets you might consider using, but to be sincere from this perspective it seems to be more like using a succession of a whole lot, 1000's or tens of thousands of smaller asteroid impacts would be a better wager.
