Billiards technique. Clonk the Earth with one thing big and heavy, inflicting it to change course. Rather than simply bouncing off, the item destroyed much of each itself and Earth, causing an enormous spray of matter to be hurled off from the affect point; this matter coagulated into what is now the Moon. 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 big amber rod might perhaps be in order - then we might use magnetic fields to drive the planet within the route we wanted it to go. The obvious main disadvantage with this methodology is that right now there aren't even theories as to how you may probably build rocket engines of the kind proposed right here. Basically, the point here is that modelling impacts like these is a tricky business. The precept here is far the same, with the railguns behaving somewhat like discretized variations of thrusters, offering instantaneous adjustments in velocity as opposed to sustained steady change.

The foremost downside right here is figuring out how to select up massive pieces of continental plate without breaking them. Atmospheric considerations are ignored right here since it's way more power-efficient to manually take away the Earth's atmosphere, move the planet, and reinstall it. Suppose that there were ten billion people (one other overestimate - there are about 6.Four billion on 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 seemingly to find - there are heavier moons and total planets you can consider using, but to be trustworthy from this standpoint it seems extra like utilizing a succession of a whole lot, 1000's or tens of hundreds of smaller asteroid impacts would be a better guess. All of it depends how fussy you are about how the Earth seems afterwards, after all. Wait lengthy enough, and the solar wind blowing the sail outwards will take the Earth outward too, since the two are gravitationally certain together! This may be employed to move the Sun and Earth in tandem to a spot the place the Earth can more simply be destroyed.

Plan it proper, and you may couple it together with the Earth with gravity alone, utilizing the photo voltaic wind to steadiness out the Earth's gravitational attraction. Alternatively, as the Earth's angular kinetic vitality is negligible in comparison with its orbital kinetic power, you would possibly consider diverting a relatively small amount of sources to simply stopping the Earth from spinning at all, earlier than beginning the primary venture. This structure wouldn't be in orbit across the Sun, however static, remaining aloft utilizing the radiation strain of catching and reflecting solar energy. With half of the Sun's radiation blocked/reflected in the opposite path, the Sun now has a web thrust upwards (i.e. within the path of the "hat"). Just use it to tack in opposition to the path wherein the Earth is travelling, progressively slowing its orbital velocity and increasing the orbit's eccentricity, till the orbit passes within the Roche restrict where the Earth is torn apart by tidal forces.

It is possible to make use of a photo voltaic sail to steer the Earth into the Sun. Better, you may use many, many asteroids one after the other in a steady stream, and reduce down the whole time significantly. Way all the way down to 1021 tonnes. You could reuse the identical asteroid repeatedly, looping it around a couple of gasoline giants and again to realize tons more kinetic energy from those fuel giants in the identical way that Earth simply gained velocity from the rock. Moving the Sun is about 6 orders of magnitude more difficult than transferring the Earth however the Sun is continuously emitting vitality which may be productively harnessed for this purpose. Direct rocket propulsion. Build gigantic, presumably nuclear upward-pointing rocket furnaces, perhaps one, maybe 4, perhaps 1,000,000, no matter you'll be able to funds for. Build an infinite lightweight "hat" for the Sun, which catches the Sun's rays. If balanced appropriately, the "hat" neither falls into the Sun nor is blown away.
