Recently found archives of the late Baron von Münchausen brought to light some unpublished scientific papers. In one of them, his calculations indicated that the Sun’s energy would some day be exhausted, with the subsequent freezing of the Earth and its inhabitants. In order to avert 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 through space to the nearest star via the Archimedes’ force on the balloon, transmitted through 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). (Moscow Phys-Tech)
