Heat Death of the Universe Quotes

In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter. Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

The arrow of time doesn't move forward forever. There's a phase in the history of the universe where you go from low entropy to high entropy. But then, once you reach the locally maximum entropy you can get to, there's no more arrow of time.

The story of the universe finally comes to an end. For the first time in its life, the universe will be permanent and unchanging. Entropy finally stops increasing because the cosmos cannot get any more disordered. Nothing happens, and it keeps not happening, forever. It's what's known as the heat-death of the universe. An era when the cosmos will remain vast and cold and desolate for the rest of time the arrow of time has simply ceased to exist. It's an inescapable fact of the universe written into the fundamental laws of physics, the entire cosmos will die.

In high school, when I first heard of entropy, I was attracted to it immediately. They said that in nature all systems are breaking down, and I thought, What a wonderful thing; perhaps I can make some small contribution to this process, myself.

The 2nd law of thermodynamics has the same degree of truth as the statement that if you throw a tumblerful of water into the sea, you cannot get the same tumblerful of water out again.

The most likely possibility, favored by current data, is that the universe will die in Ice, not Fire. However, personally I believe that trillions of years from now, we (if we are still around) will have the technology to leave the universe, perhaps in an interdimensional life boat, and move to a warmer universe.

The idea that the universe is running down comes from a simple observation about machines. Every machine consumes more energy than it renders.

Trillions of years into the future, when all stars are gone...all parts of the cosmos will cool to the same temperature as the ever-cooling background. At that time, space travel will no longer provide refuge because even Hell will have frozen over. We may then declare that the universe has died-not with a bang, but with a whimper.

Heat energy of uniform temperature [is] the ultimate fate of all energy. The power of sunlight and coal, electric power, water power, winds and tides do the work of the world, and in the end all unite to hasten the merry molecular dance.

For almost a century, the Universe has been known to be expanding as a consequence of the Big Bang about 14 billion years ago. However, the discovery that this expansion is accelerating is astounding. If the expansion will continue to speed up, the Universe will end in ice.

Question: Who governs the governors? Answer: Entropy

All things tend toward entropy. The whole universe is moving outward, the stars pulling away from one another, God knows what falling through the cracks between them.

Jacob's room is the place entropy goes to die.

but even if we survive the collapse of our sun, we will not survive forever.

As for the end of the universe…I say let it come as it will, in ice, fire, or darkness. What did the universe ever do for me that I should mind its welfare?
