String theorist and others have theories about the "big bang" or more accurately the "big inflation". Apparently matter at that time must have been moving at greater than the speed of light or space was growing at faster than the speed of light. Dark matter/energy appears to be the suspect of the energy required to inflate the universe (powerful stuff). Given there is dark matter/energy in the universe is there any concievable experiement to measure the amount of dark energy in a given unit of volume on earth. Is there a way to harness the energy to preform work? The experiments do not have to be probable just possible. If the question is inaccurate or based on false assumptions please explain with references.

Space itself was expanding at ftl speeds during the inflationary epoch, rather than matter moving through space at those speeds. The first case doesn't violate GR, but the second one would. >Dark matter/energy appears to be the suspect of the energy required to inflate the universe (powerful stuff) I don't think this is a mainstream theory - dark energy / matter aren't required by inflationary theories.
