by metric on 2006-06-19 02:21:24Assuming a 1 gram piece of cheese. At the speed of light, the kinetic energy, in joules, of the cheese would be it's velocity squared over two. Let us also assume the 1 gram of cheese is traveling at the speed of light (299792458 m/s). That would mean that this piece of cheese has about 44,937 TJ (terajoules) of energy on impact. For comparison, Little Boy released about 63 terajoules on Hiroshima. For every gram of cheese we add, this figure doubles.... it's not hard to imagine a piece of cheese capable of disintegrating 8 miles of titanium... discounting the question of what the actual mass of the titanium is. -

by anonymous on 2008-02-11 06:32:22Since the only constraint on the titanium is that there are '8 miles' of it, and the only constraint on its interaction with the cheese is that the cheese have 'enough force' to 'go through 8 miles of titanium,' the simple solution is to choose to assemble the titanium into a hollow cylinder, or 'tube' shape, eight miles long. By orienting the tube vertically on Earth's surface, the only force needed to put the cheese through it, would be that required to put the cheese at a point slightly above the top opening of the tube. Depending whether the total force measured includes construction of the tube, it might be more convenient to construct it underground or at a deep spot in the ocean, but it is physically possible.
