Turn the box over. The big box should be about the size of a stove. For example, an object the size of Mars hit Earth once in the dim and distant past. Solar sail method. I can't honestly add much to that article except to say that to move the Earth substantially, the sail used is going to have to be pretty big. The principle here is much the same, with the railguns behaving somewhat like discretized versions of thrusters, providing instantaneous changes in velocity as opposed to sustained steady change. Rather than simply bouncing off, the object destroyed much of both itself and Earth, causing a VAST spray of matter to be hurled off from the impact point; this matter coagulated into what is now the Moon. 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"). Gravity assistance. This is a method originally proposed as a means of moving Earth to a higher orbit around the Sun in order to save it from the Sun's inevitable Red Giant expansion.

He then alternately pockets red and coloured balls. 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. Thicker cloth tends to last longer but may affect ball speed slightly. 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. Hint: Use hard-boiled eggs just in case! 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. 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. Atmospheric considerations are ignored here since it is far more energy-efficient to manually remove the Earth's atmosphere, move the planet, and reinstall it.

Standard billiard balls are 2 1/4 inches in diameter, but smaller or larger sizes are available for specific variations of the game. On the next page you'll read about how a game of kubb proceeds. In our next section, we'll show you how to play the Devil's Gate game. If Team Stark knocks over all of the Lannisters' kubbs and then the king, it wins the game. In the most basic version of the game, toppled kubbs are removed from the pitch as they fall, until the king is finally taken down. 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. Better, you could use many, many asteroids one after the other in a steady stream, and cut down the total time significantly. Suppose that there were ten billion people (another overestimate - there are about 6.4 billion at the time of writing). And lastly, suppose that they all jumped at precisely the same instant, which of course they will not, seeing as the time difference between the fastest watch and the slowest will likely be over five minutes.

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. Drawbacks: as above, the momentum change you get is minuscule because you have to subtract off the 11km/s needed to launch the material upwards forever at all. Have all the kids stand in a circle around the flower bowl, starting about three or four feet away, depending on the children's age or skill level. Carom billiards is played on a table usually 5 by 10 feet (1.5 by 3 m) or 4.5 by 9 feet (1.4 by 2.7 m). Divide the players into two teams, and have each team stand about 50 feet apart, what is billiards arms linked. Chalk in small cubes is applied uniformly to the cue tip permitting the players to strike the cue ball off centre on purpose in order to impart a spinning motion, called "side" in Great Britain and "English" in the United States. Alternatively, as the Earth's angular kinetic energy is negligible compared to its orbital kinetic energy, you might consider diverting a relatively small amount of resources to simply stopping the Earth from spinning at all, before beginning the main project.
