Define Baron von Münchausen and Intergalactic Travel?
Recently get archives of the late Baron von Münchausen brought to light some unpublished scientific papers. In one of them his computation indicated that the Sun's energy would one day be exhausted, with the subsequent freezing of the Earth and its inhabitants. In order to ward off this inevitable outcome he proposed the construction of a large rigid balloon empty of all gases 1 km in radius and attached to the Earth by a long light rope of extreme tensile strength.
The Earth would be propelled by space to the nearest star by means of the Archimedes' force on the balloon, Transmitted by the rope to the large staple embedded in suitable bedrock. Estimate the force on the rope assuming a massless balloon. Discuss the feasibility of the Baron's idea without using any general statements.
newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of
