There are some principles in entropy im having trouble understanding. If Entropy requires that the energy in the universe must always been constant, shouldnt in theory 'Heat Death' have occurred since forever ago even before the Big Bang? Why not?
Entropy and energy conservation are laws often used to predict the ultimately fate of the universe. Trough achieving thermal equilibrium and dissipation of mechanical energy the universe would become in a 'Heat Death' state where nothing would really occur.
The basic principles of this theory, as I understand, is that: (1) Energy cannot be created (nor it is infinite); and (2) the Universe is a closed system;
The problem I see is that there must be a hidden number (3) requisite: Time must be finite, for this to work properly. I cant aknowledge time as being finite because then nothing could have started 'time', (you would need to have a external process [and a external time] and acknowledge that the system is not closed).
If time is infinite, then there was an infinite time before the Big Bang, then, in my understanding, the Big Bang couldn't possibly exist and have formed. Because in infinite time 'Heat Death' would always be what there is.
This wouldn't suppose that one of the 2 basic principles is wrong (or energy can somehow be created or the Universe is not closed), and Entropy really doesnt apply to the universe at all? Another explanation I see is that if the principles are true, then in fully understandment of all Universe laws Entropy itself must be wrong (the system would never achieve thermal equilibrium or a 'final state').
Either way all propositions I see for the problem achieve that Entropy must be somehow flawed in some level. What are your toughts in this? Im not a physicist and if something Im stating is wrong please enlight me!
