I was having a heated "debate" with a friend the other about the laws of thermodynamics. She kept stating that they always work therefore there is no one experiment needed to prove they work all the time. Then she started getting into the "if the opposite doesn't hold true, therefore it must work." Which I didn't understand that.

For anyone who doesn't remember here are the four laws of thermodynamics:

0.) "If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other."

1.) "In any process, the total energy remains constant." (aka: Energy nor matter can NOT be created nor destroyed)

2.) "The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a max value at equilibrium."

3.) "As temp approaches absolute zero, the entropy of a system approaches a constant."

The following questions I propose ( I only discussed with a few other people today) I came up with at about 4am yesterday morning.

* Is infinity constant? (if not then why does this hold true: 1 + (infinity) = (infinity)

* If the energy in the universe is constant; then where does matter and/or light energy inside a black hole go?

* In relation to the last one... does the "universe" include all possible, and unseen, unnoticeable, and undiscovered dimensions?

* If the energy in the universe is constant; (all matter that exists now has always existed, just in different forms) then doesn't that mean the universe is finite?

* In relation to time, if you travel into the past, wouldn't you create an unbalance of energy in the past/future with your presence missing in the "then present" and now increased in the past?

* The energy used in time travel; where would it "transfer" to, if it cannot be destroyed?

* The grandfather paradox holds true due to the 1st law; if you grandfather died it causes an unbalance along the time line therefore, would destroy your mom or dad. If destroyed; (which is impossible due to law 1 as well) where would they go?

* To build upon the law statement. If you kill your grandfather before your mother was born, she would be destroyed on the first time "line..." where would she go?

* Light is energy. Where does light go when you turn off the switch? IT has to transfer to something else. Light emits heat only white lit, but what about when it's gone?

* Is infinity prime or composite?

* If there is a finite amount of energy in the universe, then infinity can't exist. You can't count higher than the total molecules that take up the universe.

* Light has not mass, but has energy? (how... what about Engery = Mass * Light ^2)

Remember I was half-awake when I coined this up...

Enjoy

I'll throw my own thoughts into the mix.Into the black hole, I presume. It is a hole in the sense of a cavity or a hollow.
That is just a question of words. "Universe" is a word created by humanity and we a free to define it as we choose. There is no intristic connection between it and the world itself. Answer: It does if we want it to.
Merely that matter/energy is. Although a finite universe doesn't sound impossible.
I believe that the first law of thermodynamics states: "In any process, the total energy of the universe remains constant." It doesn't say when in the universe the energy has to be. This of course presumes that time travel would be possible.
You need energy to time travel? I didn't know that. Maybe it works the same as travel through spatial dimension and becomes time-kinetic energy?
Nobody said it has to be balanced across time any more than across space.
It spreads out or is absorbed into matter. Just because you can't see light doesn't mean it isn't there, only that there isn't enough of it in the right spectrum.
Who said mathematics is bound by matter, or how far you can count? Even with an infinite amount of matter you could never count to infinity.
Energy = mass * (speed of light)^2. Even though a photon has no mass, light has a relativistic mass in form of energy. It has momentum and can exert pressure.

I always found the second law to be curiously vague.

Cool video, I started watching. I'm looking to finish it tonight.

does the "universe" include all possible, and unseen, unnoticeable, and undiscovered dimensions?

Actually the term "multiverse" was coined to refer to all dimensions, or planes of existence. However, in this context, I would say yes, it would contain all dimensions. For instance, if energy moves to an alternate dimension, like, say a soul going to Valhalla, then in order to preserve conservation of energy Valhalla must count as part of the "Universe". The Big Bang theory, which explains the "universe", relies on energy from another dimension to set it off, like perhaps a tachyon moving backward in time from a possible future.
