Gravity assistance. This is a technique originally proposed as a technique of shifting Earth to a better orbit across the Sun with a view to save it from the Sun's inevitable Red Giant growth. Which implies the gap the Earth strikes when everybody jumps will likely be one trillionth of the distance that all the people jumped: that's to say, 10-11 metres, or about half the radius of a hydrogen atom. Since the Sun carries the vast majority of the complete mass of the photo voltaic system, any pressure which strikes it is likely to drag the entire planets together with it. It's because general it carries nearly precisely zero overall cost. If there was some way to electrically charge the Earth, by dumping plenty of identically charged particles onto the Earth or just ionizing particles already on Earth - a large amber rod might maybe be in order - then we could use magnetic fields to drive the planet in the route we wanted it to go. Alternatively, as the Earth's angular kinetic power is negligible in comparison with its orbital kinetic energy, you may consider diverting a relatively small quantity of resources to easily stopping the Earth from spinning at all, before beginning the primary venture.

You never know if you may wish to significantly alter the orbital path of the Earth. Maybe it is not, however you want it to. Maybe you wish to destroy it: a significant variety of strategies for destroying the Earth involve moving it by some substantial amount. It will get higher. Even assuming the Earth did move by some important distance when everyone jumped, simply give it some thought: it'd move right again once more! Suppose everyone on the planet weighed 100kg (which is an overestimate, 70kg is extra prefer it, most likely much less). Getting everybody on the planet to jump at the identical time. Suppose they have been all at the very same level on Earth (which they will not be, thus mitigating the consequences of the jump). You soar up, the Earth goes down: you fall down, the Earth comes up to meet you. Just use it to tack towards the path by which the Earth is travelling, steadily slowing its orbital velocity and growing the orbit's eccentricity, till the orbit passes within the Roche limit where the Earth is torn apart by tidal forces.

The principle here is far the identical, with the railguns behaving somewhat like discretized variations of thrusters, offering instantaneous modifications in velocity as opposed to sustained regular change. Better, you might use many, many asteroids one after the other in a steady stream, and minimize down the overall time considerably. Way right down to 1021 tonnes. Altogether that's 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 may repeat this thousands of times over the course of millions of years. This leads to a minute theoretical acceleration but over millions of years the velocity would accumulate to one thing substantial. Belgium. Design them fastidiously so that when used the rocket engines do not actually just propel themselves by way of the ground and into Earth where they turn out to be ineffective - it's possible you'll have to periodically dig them out again after several thousand years' continued thrusting, or else just construct new ones excessive. The most obvious major downside with this technique is that proper now there aren't even theories as to how you would probably construct rocket engines of the type proposed here. Rather than simply bouncing off, the object destroyed much 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.

With half of the Sun's radiation blocked/reflected in the other course, the Sun now has a internet thrust upwards (i.e. within the path of the "hat"). This can be employed to maneuver the Sun and Earth in tandem to a place where the Earth can more simply be destroyed. Suppose that all of them jumped ten metres in the air (a huge overestimate, fifty centimetres is extra probably and probably a lot less). Suppose that there have been ten billion people (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 are possible to search out - there are heavier moons and complete planets you would think about using, but to be honest from this standpoint it seems extra like utilizing a succession of lots of, thousands or tens of 1000's of smaller asteroid impacts can be a better wager.
