Gravity assistance. This is a method originally proposed as a technique of moving Earth to the next orbit across the Sun with the intention to put it aside from the Sun's inevitable Red Giant enlargement. Which implies the space the Earth moves when everyone jumps will likely be one trillionth of the gap that all of the individuals jumped: that's to say, 10-eleven metres, or about half the radius of a hydrogen atom. Since the Sun carries the overwhelming majority of the complete mass of the solar system, any drive which moves it is likely to drag the entire planets along with it. It is because total it carries nearly precisely zero total cost. If there was some solution to electrically charge the Earth, by dumping a lot of identically charged particles onto the Earth or just ionizing particles already on Earth - a large amber rod would possibly maybe be in order - then we could use magnetic fields to drive the planet within the direction we needed it to go. Alternatively, as the Earth's angular kinetic vitality is negligible in comparison with its orbital kinetic power, you may consider diverting a comparatively small quantity of assets to easily stopping the Earth from spinning at all, before starting the main project.

You never know if you would possibly wish to considerably alter the orbital path of the Earth. Maybe it is not, however you want it to. Maybe you need to destroy it: a major number of strategies for destroying the Earth involve shifting it by some substantial quantity. It will get better. Even assuming the Earth did move by some important distance when all people jumped, just think about it: it'd transfer proper back again! Suppose all people on the planet weighed 100kg (which is an overestimate, 70kg is more like it, probably much less). Getting everyone on the earth to jump at the identical time. Suppose they had been all at the very same point on Earth (which they won't be, thus mitigating the effects of the leap). You jump up, the Earth goes down: you fall down, the Earth comes up to meet you. Just use it to tack in opposition to the course by which the Earth is travelling, regularly slowing its orbital velocity and increasing the orbit's eccentricity, until the orbit passes inside the Roche restrict where the Earth is torn apart by tidal forces.

The precept here is way the identical, with the railguns behaving considerably like discretized variations of thrusters, providing instantaneous adjustments in velocity versus sustained steady change. Better, you could possibly use many, many asteroids one after the opposite in a steady stream, and cut down the overall time considerably. Way down to 1021 tonnes. Altogether that is a mass of one billion tonnes of humanity leaping ten metres in the air. That's a trillion times heavier than all of humanity. You could repeat this 1000's of instances over the course of thousands and thousands of years. This ends in a minute theoretical acceleration but over hundreds of thousands of years the velocity would accumulate to one thing substantial. Belgium. Design them rigorously so that when used the rocket engines don't actually just propel themselves through the bottom and into Earth the place they change into ineffective - you might have to periodically dig them out once more after a number of thousand years' continued thrusting, or else just construct new ones over the top. The obvious major disadvantage with this method is that right now there aren't even theories as to how you may possibly construct rocket engines of the sort proposed here. Rather than merely bouncing off, the object destroyed much of each itself and Earth, inflicting an enormous spray of matter to be hurled off from the impression point; this matter coagulated into what is now the Moon.

With half of the Sun's radiation blocked/mirrored in the opposite path, the Sun now has a internet thrust upwards (i.e. in the direction of the "hat"). This can be employed to maneuver the Sun and Earth in tandem to a place 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 likely and probably much less). Suppose that there were ten billion individuals (one other overestimate - there are about 6.Four billion at the time of writing). 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 doubtless to seek out - there are heavier moons and total planets you could consider using, but to be sincere from this perspective it seems extra like using a succession of a whole bunch, thousands or tens of thousands of smaller asteroid impacts could be a better bet.
