In Theoretical Physics , the '''Boomeranger''' is a "proof of concept" thought experiment by the physicist John Wheeler , which shows that some behaviours associated with a hypothetical Warp Drive or Inertial Drive are achievable using standard physics. In this second context, boomeranging means travelling in such a way as to be able to reach a destination and return with no apparent overall energy cost. WARP SPEED WITHOUT WARP DRIVE Wheeler's exercise describes a stationary object being picked up, accelerated to high speeds without feeling Geeforces and decelerated again to rest as it approaches its destination (again without geeforces), all without any obvious round-trip energy expenditure. Wheeler's suggestion does not require Exotic Matter , Antigravity , strange Warp Metric s or any other aspects of advanced theory, it simply requires a tunnel drilled (somewhat impractically) through the centre of the earth, preferably evacuated. When a package is to be sent, it is simply dropped into the shaft. The Earth's gravity accelerates the object towards the centre of the planet until the speed reaches about ~18,000 mph (7.9 km/s) at the centre, after which the object begins to lose speed as it hurtles "uphill" again towards the earth's surface at the far side, coming to rest at ground level at the other side. At this point it is grabbed by someone before it can fall back down the shaft to repeat its journey in reverse. The entire trip from one side of the Earth to the other (ignoring density variations and the Earth's rotation) is calculated by Wheeler to take 42 minutes. REFERENCES
