energy can't be created or destroyed, but did energy come after the big bang?

    Many physicists believe in the zero energy universe. Most energy is positive - energy from mass, kinetic energy, energy density of electromagnetic fields, etc.

    However, it is well known that gravitational potential energy is negative, and it can be shown that the positive and negative energy sums to zero - with a little bit of sleight of hand ...

    The slight of hand is how we actually compute the energy of a gravitational field since it is not included in Einstein’s field equations. We use mathematical objects that are not the same as the mathematical objects that are used in cosmological solutions of general relativity. That coupled with the fact that there is no global notion of energy conservation in a curved spacetime, makes it a little dicey. 

    That being said, it does make sense and explains why there was no clear violation of energy conservation at the creation of the universe.

    the closed system principle requires a closed system to be true.  the moment of the big bang is not a closed system.  everything in the system is added at that moment.  Obviously, in a larger view of "system", the energy was taken or derived from somewhere, but it does not have to have existed as "energy" as we understand it.

    The Big Bang was ALL energy, a white hole. Matter and energy are interchangeable. Where all that energy came from we do not know. Become a theoretical physicist and become part of the team that figures it out.

    The first thing being created by GOD is the first pure energy that has no form  but can perform work being ignited and then expand to  be universe that consist of mass being filled in space , then from these three entities melted together to be time dimension , in such a way that all these four entities can not exist with out one another. So to conclude , .energy was the cause and then big bang become effected  .
