Maybe Earth is about to hit an asteroid. Moving the Sun is about 6 orders of magnitude tougher than transferring the Earth but the Sun is continuously emitting vitality which can be productively harnessed for this goal. 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 sources to easily stopping the Earth from spinning at all, what is billiards before starting the primary mission. Maybe you need to destroy it: a significant number of strategies for destroying the Earth contain transferring it by some substantial amount. It will get higher. Even assuming the Earth did move by some significant distance when all people jumped, just think about it: it’d transfer right back once more! This can be employed to move the Sun and Earth in tandem to a spot the place the Earth can more easily be destroyed. Atmospheric issues are ignored right here since it is way more vitality-environment friendly to manually remove the Earth’s atmosphere, move the planet, and reinstall it. Disassemble, move the bits and pieces, reassemble. Jumping up and right 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 move forwards.
Altogether that is a mass of 1 billion tonnes of humanity jumping ten metres within the air. Suppose that they all jumped ten metres in the air (a huge overestimate, fifty centimetres is extra seemingly and possibly a lot less). 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’re probably to search out – there are heavier moons and total planets you might consider using, however to be honest from this point of view it appears to be like extra like utilizing a succession of hundreds, hundreds or tens of hundreds of smaller asteroid impacts could be a greater bet. Basically, the point right here is that modelling impacts like these is a difficult enterprise. Note that the Earth doesn’t and will not behave like a stable, inflexible billiard ball beneath such enormous impacts as these. Wait long sufficient, and the photo voltaic wind blowing the sail outwards will take the Earth outward too, since the two are gravitationally sure collectively!
Solar sail technique. I am unable to truthfully add much to that article except to say that to maneuver the Earth substantially, the sail used is going to should be pretty large. Maybe. Or higher but: the Earth already has a standing magnetic field; maybe we could assemble a cylinder of cable around it, and go present to maneuver it utilizing Lorentz forces. Just use it to tack against the path during which the Earth is travelling, step by step slowing its orbital velocity and increasing the orbit’s eccentricity, until the orbit passes throughout the Roche limit the place the Earth is torn apart by tidal forces. Billiards methodology. Clonk the Earth with something large and heavy, inflicting it to change course. Let me emphasize the words “huge”, “heavy” and “clonk”. Electromagnetic affect. Traditionally the Earth is regarded as “floor”, “impartial”. Belgium. Design them rigorously in order that when used the rocket engines do not really just propel themselves via the ground and into Earth the place they grow to be useless – you might have to periodically dig them out once more after a number of thousand years’ continued thrusting, or else just construct new ones excessive. The obvious major drawback 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 right here.
Gravity help. This is a technique initially proposed as a technique of shifting Earth to the next orbit around the Sun with a purpose to put it aside from the Sun’s inevitable Red Giant expansion. It is possible to use a photo voltaic sail to steer the Earth into the Sun. It includes asteroids, just like the above method, only instead of direct impacts, this time we just steer them previous the Earth, allowing rock and planet to exchange a bit momentum, with the result of an Earth shifting on a slightly completely different observe and an asteroid shifting on a significantly different one. If there was some option to electrically cost the Earth, by dumping a number of identically charged particles onto the Earth or simply ionizing particles already on Earth – a large amber rod might perhaps be so as – then we might use magnetic fields to drive the planet in the path we needed it to go.
