If there was some way to electrically charge the Earth, by dumping lots of identically charged particles onto the Earth or just ionizing particles already on Earth - a large amber rod might perhaps be in order - then we could use magnetic fields to drive the planet in the direction we wanted it to go. WAY down to 1021 tonnes. According to the rules, each round continued until a man went down. Once a man was down, he was allowed to rest for 30 seconds. You jump up, the Earth goes down: you fall down, the Earth comes up to meet you. Getting everybody in the world to jump at the same time. Direct matter propulsion. Same method as above, just using gigantic mass drivers/railguns to fire huge quantities of matter away from Earth, instead of a rocket exhaust. This structure would not be in orbit around the Sun, but static, remaining aloft using the radiation pressure of catching and reflecting solar energy.

Maybe. Or better yet: the Earth already has a standing magnetic field; perhaps we could construct a cylinder of cable around it, and pass current to move it using Lorentz forces. Construct a huge solar sail with a significant mass. Wait long enough, and the solar wind blowing the sail outwards will take the Earth outward too, since the two are gravitationally bound together! The billiard balls, formerly made of ivory or Belgian clay, are now usually plastic; they each measure from about 21/4 to 23/8 inches (5.7 to 6 cm) in diameter, the larger balls being used in carom billiards. Carom, or French, billiards is played with three balls on a table that has no pockets. The other principal games are played on tables that have six pockets, one at each corner and one in each of the long sides; these games include English billiards, played with three balls; snooker, played with 21 balls and a cue ball; and pocket billiards, or pool, played with 15 balls and a cue ball. It is most common in traditional billiards to use only three balls. The objective is to pocket all your designated balls (either solids or stripes) and then sink the 8 ball to win the game.

The player must first pocket a red ball and then try to pocket any colour he may choose, scoring the value of the ball that he has pocketed. Plotting acceleration vectors towards whatever your target is in this case may prove to be a nontrivial problem, solvable only with high-tech computer simulations. Belgium. Design them carefully so that when used the rocket engines do not actually just propel themselves through the ground and into Earth where they become useless - you may need to periodically dig them out again after several thousand years' continued thrusting, or else just build new ones over the top. The major problem here is figuring out how to pick up big pieces of continental plate without breaking them. Another, more sophisticated, problem is that the Earth is constantly spinning. Billiards method. Clonk the Earth with something big and heavy, causing it to alter course. Let me emphasize the words "big", "heavy" and "clonk". Sports and recreation, unstructured and often violent in the 1700s, also included horse racing and boxing. The development of the sport of horse racing began with the support of Charles the II, causing Newmarket to become the center of English racing.

You could reuse the same asteroid again and again, looping it around a few gas giants and back to gain lots more kinetic energy from those gas giants in the same way that Earth just gained velocity from the rock. Just use it to tack against the direction in which the Earth is travelling, gradually slowing its orbital velocity and increasing the orbit's eccentricity, until the orbit passes within the Roche limit where the Earth is torn apart by tidal forces. With half of the Sun's radiation blocked/reflected in the opposite direction, the Sun now has a net thrust upwards (i.e. in the direction of the "hat"). Build an enormous lightweight "hat" for the Sun, which catches the Sun's rays. Carom shots require precise control of the cue ball’s speed and direction, making them a great way to showcase your mastery of cue ball manipulation. When executing a safety shot, focus on positioning both the cue ball and target balls in such a way that it becomes challenging for your opponent to make an easy next move. To execute a successful bank shot, start by visualizing the path that you want your target ball to take after bouncing off the cushion.
