The more time you spending in measuring your experiment (thus standard deviation will become smaller) the more precisely you will measure energy of this system.... energy time uncertainly principle implies this.... and in most systems (i have seen,or may be all systems ) the lowest possible energy is ground state energy, this energy cannot be removable.. for example in a infinit square well .. Then how can ''universe from nothing'' i would say sentence makes sense? if there is uncertainly how there is something like nothing... if minimum energy possible is ground state energy..how nothing(no energy exist)???

What is "nothing"? Can somebody please get this experimentalist a couple of liters of "nothing", so that he can do some basic physical measurements on "nothing"?
Moreover, can someone point me to a paper where the total energy of the universe has been measured experimentally?
