Does the first law of thermodynamics disprove the Big Bang?

It is impossible to determine whether the first law of thermodynamics was in effect at the beginning of the universe, but it governs all physical and chemical processes in it. As you can see, I have avoided discussing any period of time that preceded the Big Bang, because there never was.

No, the first law of thermodynamics does not disprove the Big Bang theory. The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. The Big Bang theory does not violate this law, as it does not claim that energy was created out of nothing, but rather that the universe underwent a rapid expansion from an extremely hot and dense state. The total energy of the universe remains constant, but its form and distribution change over time.

No, the first law of thermodynamics does not disprove the Big Bang theory. The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. This law is consistent with the Big Bang theory, which proposes that the universe originated from a singular point of extremely high energy density and temperature. According to the theory, the universe expanded and cooled over time, allowing for the formation of matter and energy in various forms. The first law of thermodynamics does not contradict this process but rather provides a framework for understanding the conservation of energy throughout the universe's evolution.
