Is the history behind the theory of a singularity exploding leading to the implication that the universe is inherently more unstable than previously presumed?

Answer 1

In my opinion this question highlights the conflict between the 2 laws of thermodynamics.

The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.

The Second Law of Thermodynamics states that in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state. This is also commonly referred to as entropy.

Therefore if an 'expanding' or 'exploding' singularity created the Universe, the 1st Law states that all of the energy within that initial singularity must still be present in the Universe today and must remain within the Universe 'if' no energy enters or leaves the system.

Whereas the 2nd Law states that potential energy of the Universe will always be less than that of the initial state.

Some Physicists theorize that a Black Hole eventually decays, consuming the total energy within it - meaning energy leaves the system . . . and therefore abolishing both Laws of Thermodynamics in the process.

Others suggest a multi-verse, or multiple string dimensional universe . . . which means that 'energy enters the system', also abolishing both Laws of Thermodynamics is the process.

However, if the initial energy from the Big Bang remains in the Universe, The 1st Law leaves open the possibility that eventually another Big Bang could occur within the Universe, meaning that the Universe possibly could be more unstable than previously presumed, while the 2nd Law completely rules that possibility out.

Basically, physicist's, astrophysicist's and quantum physicist's still do not know the nature of our universe completely, nor the eventual outcome of the Universe. All is still theory.
