Altogether that's a mass of one billion tonnes of humanity leaping ten metres in the air. That's a trillion times heavier than all of humanity. 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 probably to search out - there are heavier moons and whole planets you might consider using, but to be trustworthy from this point of view it looks extra like using a succession of a whole bunch, 1000's or tens of thousands of smaller asteroid impacts could be a better wager. If there was some option to electrically charge the Earth, by dumping plenty of identically charged particles onto the Earth or simply ionizing particles already on Earth - a big amber rod would possibly perhaps be so as - then we might use magnetic fields to drive the planet in the direction we wanted it to go. You possibly can reuse the same asteroid again and again, looping it around a number of fuel giants and again to realize heaps extra kinetic power from these gasoline giants in the identical means that Earth simply gained velocity from the rock.

Getting everybody on the planet to leap at the identical time. You bounce up, the Earth goes down: you fall down, the Earth comes up to meet you. Suppose they had been all at the exact same point on Earth (which they will not be, thus mitigating the effects of the bounce). And lastly, suppose that they all jumped at exactly the same immediate, which of course they will not, seeing because the time difference between the quickest watch and the slowest will doubtless be over five minutes. Direct matter propulsion. Same method as above, simply using gigantic mass drivers/railguns to fire large quantities of matter away from Earth, as an alternative of a rocket exhaust. Gravity help. This is a technique initially proposed as a means of transferring Earth to a higher orbit around the Sun in order to put it aside from the Sun's inevitable Red Giant expansion. Maybe the Sun goes Red Giant and also you miss the days when lead didn't melt in direct sunlight. Solar sail method. I can't actually add much to that article except to say that to move the Earth substantially, the sail used goes to should be fairly big. Certainly, no single impact is going to do all of the course altering you may be wanting to tug off.

Billiards method. Clonk the Earth with one thing huge and heavy, inflicting it to alter course. The most obvious major disadvantage with this methodology is that proper now there aren't even theories as to how you could presumably construct rocket engines of the sort proposed here. It will get higher. Even assuming the Earth did transfer by some significant distance when all people jumped, simply think about it: it'd move proper again once more! Which means the gap the Earth strikes when all people jumps will likely be one trillionth of the space that all the people jumped: that's to say, 10-11 metres, or about half the radius of a hydrogen atom. Note that the Earth does not and will not behave like a solid, inflexible billiard ball below such large impacts as these. Maybe Earth is about to hit an asteroid. It entails asteroids, like the above method, solely as a substitute of direct impacts, this time we simply steer them previous the Earth, permitting rock and planet to alternate just a little momentum, with the result of an Earth transferring on a barely different observe and an asteroid moving on a considerably different one. Rather than simply bouncing off, the item destroyed much of both itself and Earth, causing an unlimited spray of matter to be hurled off from the influence level; this matter coagulated into what is now the Moon.

Suppose that they all jumped ten metres within the air (a huge overestimate, fifty centimetres is more likely and doubtless a lot much less). The principle right here is much the same, with the railguns behaving somewhat like discretized versions of thrusters, providing instantaneous adjustments in velocity versus sustained steady change. Better, you might use many, many asteroids one after the opposite in a gentle stream, and minimize down the full time significantly. Way right down to 1021 tonnes. Jumping up and down to try to move the Earth is like mounting a fan on a sailboat, pointing the fan at the sail, and expecting the boat to move forwards. The Earth could be very massive, moving very quick, and therefore very difficult to cease or even decelerate. Just use it to tack in opposition to the course during which the Earth is travelling, step by step slowing its orbital velocity and rising the orbit's eccentricity, until the orbit passes within the Roche restrict where the Earth is torn apart by tidal forces. This structure would not be in orbit around the Sun, however static, remaining aloft using the radiation pressure of catching and reflecting solar vitality. With half of the Sun's radiation blocked/mirrored in the opposite path, the Sun now has a net thrust upwards (i.e. within the route of the "hat").
