Riggs, Peter J.2015-12-172015-12-170836-1398http://hdl.handle.net/1885/95085The reality of energy is occasionally questioned in the physics literature despite strong arguments and experimental evidence in favor of its existence. The Ice Comets Contention is a scenario where two comets made of ice collide and melt. The heat that melts the comets is assumed to 'flow' from one comet to the other but the direction of heat flow is inferred to be observer dependent. This result is used to conclude that energy is not real. It is shown why this attempt fails.© 2010 Physics Essays Publications. http://www.sherpa.ac.uk/romeo/issn/0836-1398/..."author can archive post-print (ie final draft post-refereeing).
