It's a very well known fact that no process has 100% achievable efficiency. Eventually all unused work turns into heat friction and is cooled off by the atmosphere.
But it makes me wonder with that process that since although human life lives and dies, throughout the course of the lifespan efficiency is once again lost due to heat friction. With each birth shows less energy than it's predecessor.
It's not just human life, it's everything. The planet...hell the entire solar system does not sustain 100% efficiency for anything because once again due to heat friction.
So if all efficiency is dimminished, then where does that leave the solar system's future in the long run? Scientists already prooved that due to the big bang was the start of the energy, yet from there the universe does nothing but accelerated expansion. If there's going to be nothing but dissapated energy....how is it expanding?

As of now, the expansion is thought to be the result of the universe exerting a force that repels gravitational forces. And energy isn't created or destroyed as stated in the first law of thermodynamics. So therefore, the dissipated energy is stored somewhere as internal energy. It's a cycle.

Father Knows Best o It's a very well known fact that no process has 100% achievable efficiency. Eventually all unused work turns into heat friction and is cooled off by the atmosphere.

Scientists already prooved that due to the big bang was the start of the energy, yet from there the universe does nothing but accelerated expansion. If there's going to be nothing but dissapated energy....how is it expanding? A very very good short story written on what you are talking about. Entropy.

Asimov is the s**t, dude.
EDIT: Oh damn, now I get it. It took some thinking but those basic quantum mechanics theories came back. That's right. The universe ultimately seeks chaos, however smaller parts within it can try to reverse this process on their respective scale. Yet generally, heat energy becomes useless and virtually unusable. Once entropy is at a maximum within a system, specifically within the universe, its up in the air about what will happen. Perhaps it will never reach that if the expansion reverses direction known in theory as the Big Crunch. But as of now there is no proof of said action occurring.

Well as you just said, the universe is expanding and also to boot it's an accelerated expansion. So that said, how is a Big Crunch even possible?

Perhaps when the total entropy or size of the universe reaches a certain point, the cosmological constant that is accelerating the universe's expansion will become negative and hence reverse the process. Yet I don't know much about the specifics of the science. Regular physics blew my mind enough, so this stuff is beyond me.

Well as you just said, the universe is expanding and also to boot it's an accelerated expansion. So that said, how is a Big Crunch even possible? The thing is, under current theories, the universe actually has a shape. If you do straight in one direction constantly, you could end up back where you started. That's a theory. Basically, the universe is not as infinite as we think it is. Also, it is highly possible that this is not the first universe, or even that there are many other universes that exist inside an even larger system. Much like solar systems inside of a galaxy. We just don't know. Regardless, there is no such thing as infinite energy. Yes, you can't get rid of energy or matter, but think of it like this; If you burn a log, can you put the ashes back together and burn them again? The universe is kind of like that. Asimovs idea though, is that eventually, we will figure out a way to reverse the whole process, the problem is that it will take much longer than man could exist. I think he's wrong, just for the record. I think we'll figure something out, we always do.

Asimov is the s**t. He makes complicated ideas like this relatively easy to comprehend. At least as abstract as a human mind can analyze, since ideas like that are figuratively impossible to answer truthly; it's all guessing.

The power to reverse entropy is, as he said, the power of a god or an entity with powers beyond our universe. And I doubt even in our most evolved state will we be able to refute such a steadfast law. Granted how far we've gotten as of now, it's all been in concordance with the laws of the universe. And when faced with obstacles like flight - well, man found a certain configuration of materials allowed for flight and with the laws of physics he was able to achieve flight. There was always a loophole. But this is the brick wall of problems. A direct violation of laws set down by the universe itself.

You have to remember though, a law of the universe isn't exactly set into stone as many think. It's just called a law because the same outcome is attainable through thinkable means over and over.
