If the whole world is created from zero point energy, then the question will remain; what created the zero point energy? Following article tries to answer that question.

Chapter Consciousness and energy

If there was no big bang then how would you explain the experimentally verified fact that the universe is expanding and the existence of cosmic microwave background with 2.7 K temperature?

@Vikram Zaveri, ZPE comes from uncertainty principle delta(E)*delta(t)~h/4*pi. It traduce the quantum fluctuations of vacuum. When there is nothing, this nothing has an energy equal to h*nu/2. But the problem is how much of this half quantum exist in the universe?

@Rami Zouari

All experimental verification relating ZPE are based on data available at present epoch in the history of the universe. At the present epoch it is observed that the random motion corresponding to the zero-point energy never vanishes as a consequence of the uncertainty principle. In my theory I propose that this is not true for all epochs. e.g. at Planck epoch, when the particle acquires planck energy, it is no longer capable of acquiring more energy. When it tries to acquire more energy then the particle wave collapses and there is absolute ceasation of motion. Which means no brownian motion and no temperature due to kinetic energy. This means beyond the Planck epoch there is no zero point energy or any kind of energy at all. This is because there is absolutely no motion. And the energy is always associated with the motion. Without motion there cannot be any energy. This motionless state exists beyond the planck epoch. It is like an ocean without any waves. So if there was no ZPE at the Planck epoch, then how the universe can arise from ZPE?
