Cosmic energy flow can be visualized as the movement of energy from a point of positive ‘cosmic potential’ to a point of negative ‘cosmic potential’ analogous to the electrical energy. Movement of cosmic ‘energy particles’ is synonymous with the cosmic energy flow from the positive to negative points. At any given instant the ‘energy particles’ are in constant random motion throughout the universe (like the chain reaction in a nuclear phenomena). The movement of ‘energy particles’ can be understood by considering a point of negative potential at an instant. Energy flows from the neighborhood points with positive potential and as a result of this process the point acquires a positive potential. Due to this, at least one point in the neighborhood acquires a negative cosmic potential. Unlike a nuclear reaction the universe does not have any spatial restrictions. So this chain reaction ‘seems’ to be under control. ‘Cosmic explosion’ is the result when the chain reaction reaches a ‘critical point’. This can be considered as the point when the universe will cease to exist.
