Einstein's theories of relativity are not just idle speculation about a universe distant and unfeeling to the everyday lives of humanity.  Relativity, both general and special, has many applications to modern technology.  Many devices that form the basis of electronics and communications technology deal with particles that move fast enough that relativistic effects have to be taken into account.  Satellites for television and telephone signals, as well as any global positioning system, have to take into account the effects from their high speeds and from the Earth's gravity in order for their calculations to be accurate enough to be useful.  The entire idea that matter can be transformed into energy was inferred from relativity and is the basis upon which nuclear power operates.
