Hi Marcus, and thanks for a thorough reply! I find this very interesting, even if I don't understand relativity more than really fundamentally. I will look into Sean Carroll and John Baez, sounds really good. About the leash - We could always just connect it to the moon if its too hard to...

Say that you would connect our galaxy to a distant one with a leash, and connect the leash to a generator. Say that you generate equally much electricity (converted from kinetic energy of the galaxies) from the galaxies as they would otherwise "speed up" due to the accelerated expansion of the...

Okay, that is very interesting! I thought energy never can be created, no matter how small or large the system is, that's what I was taught in school. So would it theoretically be possible to convert this energy into work?

Hi, Is the fact that the expansion of the universe accelerates consistent with the conservation of energy? If so, how? Grateful for response!

Ok, I understand. That clearly makes my idea impossible with vapor-liquid equilibrium. Thanks! But in order for the second law to hold, it would also have to be that the equilibrium constant of any chemical reaction that can change pressure, or indirectly perform work, can never be dependent...

To clarify: The black dot in the middle is the body which emits radiation from being warm. The half circle, and the circle with a little opening, as indicated in the drawing, are the mirrors

Hello! I have another idea for how to break the second law of thermodynamics, and I don't see where this one cracks either. I would be glad if someone could explain this to me. Kelvin-Planck statement of the second law: "No process is possible whose sole result is the absorption of heat...

If the ratio between liquid water and gasous water doesn't matter, how can the reaction be said to be in DYNAMIC equilibrium? State as in state of matter, right? Liquid or gas in our case. It is precisely the increase/decrease of pressure that I use to power the generator. The...

What else would russ_watters mean by this?:

That would mean that it is impossible for a chemical reaction involving different states of matter to exist in dynamic equilibrium. I don't think that's true. See this link: http://en.wikipedia.org/wiki/Dynamic_equilibrium I read your links, but nothing there explains why my idea doesn't work?

You mean mixing an acid and a base produces H2O, not CO2. But that completely contradicts what this formula says: K = \frac{[A]^2}{[B]\times[C]}

I appreciate your help russ_watters, but I don't see how a steam table can answer this question. Forget about a vapor-liquid equilibrium, it is a chemical equilibrium instead. I thought I was just simplifying the problem, but apparently not. Below is the formula for chemical equilibrium...

I still don't understand. Once I separated the gas from the liquid (whether its a vapor-liquid equilibrium, or a chemical equilibrium for an ordinary chemical reaction), why wouldn't 50 % of the gas in the gas container condense, and why wouldn't 50 % of the liquid in the liquid container...

Thanks for your reply! I thought vapor-liquid equilibrium was just like chemical equilibrium, but for states of matter instead of a chemical reaction with products and reactants. I know that for a chemical reaction, if you remove a product, or a reactant, you will disrupt the equilibrium, and...

Hi! I have an idea for how to break the second law of thermodynamics, and I don't see where it cracks. I would really appreciate if someone could explain this to me. Kelvin-Planck statement of the second law: "No process is possible whose sole result is the absorption of heat from a reservoir...
