Quantum Theory

How can something come out of nothing as long as the energy is given back eventually? Is there a time limit? Could it be used as an arguement for a closed universe and that maybe we are an example of just such a quantum phenominon?

With our current level of knowledge we just have to accept that certain things happen. We know what happens but we don't know how or why.

Because of HUP (Heisenberg Uncertainty Principle): the uncertainty ΔE on the measured energy of a system cannot be less than h/2Δt where Δt is the measure's duration. So, the less is Δt, the higher must be ΔE, so the system can reach very high energies. Said in another way: in a very small time, our planet (or more) could disappear and something else with the same energy reappear immediately after.

Don't know.
