The principle right here is much the identical, with the railguns behaving considerably like discretized variations of thrusters, providing instantaneous changes in velocity versus sustained regular change. Better, you might use many, many asteroids one after the opposite in a steady stream, and minimize down the full time considerably. The Earth may be very large, transferring very fast, and subsequently very difficult to cease and even decelerate. Just use it to tack in opposition to the route 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 restrict the place the Earth is torn apart by tidal forces. You could possibly reuse the identical asteroid repeatedly, what is billiards looping it around a few gas giants and back to achieve lots more kinetic power from these fuel giants in the identical method that Earth simply gained velocity from the rock. This ends in a minute theoretical acceleration but over tens of millions of years the velocity would accumulate to one thing substantial.

Plotting acceleration vectors in the direction of no matter your goal is in this case might prove to be a nontrivial problem, solvable only with high-tech pc simulations. Belgium. Design them carefully so that when used the rocket engines do not actually just propel themselves by way of the ground and into Earth the place they grow to be useless - it's possible you'll need to periodically dig them out once more after several thousand years' continued thrusting, or else just build new ones over the top. Direct rocket propulsion. Build gigantic, presumably nuclear upward-pointing rocket furnaces, possibly one, possibly 4, perhaps 1,000,000, whatever you'll be able to price range for. Build an unlimited lightweight "hat" for the Sun, which catches the Sun's rays. This construction would not be in orbit across the Sun, but static, remaining aloft using the radiation pressure of catching and reflecting solar vitality. Gravity assistance. This is a method initially proposed as a means of shifting Earth to a higher orbit across the Sun in order to reserve it from the Sun's inevitable Red Giant expansion.

Since the Sun carries the overwhelming majority of all the mass of the solar system, any power which moves it's more likely to drag all the planets along with it. Ceres, the photo voltaic 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 likely to find - there are heavier moons and complete planets you could think about using, however to be honest from this standpoint it looks extra like utilizing a succession of a whole bunch, 1000's or tens of hundreds of smaller asteroid impacts would be a better guess. Jumping up and right down to strive to maneuver the Earth is like mounting a fan on a sailboat, pointing the fan at the sail, and anticipating the boat to maneuver forwards. Way right down to 1021 tonnes. Altogether that's a mass of 1 billion tonnes of humanity jumping ten metres in the air.

Suppose that all of them jumped ten metres in the air (an enormous overestimate, fifty centimetres is more possible and probably a lot less). This can be employed to maneuver the Sun and Earth in tandem to a place where the Earth can more easily be destroyed. Unfortunately, that place must be immovable, which is not possible. Also, what he did not specify is that he also needs an equally immovable fulcrum - equally impossible - and a lever of beautiful size which is unbreakable. Note that the Earth doesn't and won't behave like a strong, inflexible billiard ball beneath such huge impacts as these. Basically, the point here is that modelling impacts like these is a tricky business. It involves asteroids, like the above method, solely instead of direct impacts, this time we just steer them previous the Earth, permitting rock and planet to exchange a bit momentum, with the results of an Earth moving on a barely completely different track and an asteroid moving on a significantly completely different one. Rather than simply bouncing off, the object destroyed a lot of both itself and Earth, inflicting a vast spray of matter to be hurled off from the impression point; this matter coagulated into what's now the Moon.
