Entropy only increases in a perfectly closed system. So the simple answer is the Universe isn't completely closed. There are interdimensional holes. Like those caused by black holes but there are other types as well. The universe exists in a multidimensional set of planes this can allow energy to flow in or out.
The closest would be your sun. It produces tons of energy everyday. One only need to devise efficient ways of harvesting it.
I have read of the concept of a Dyson Sphere to harvest almost all of it.
Yes advanced civilizations utilize that method often. Interestingly some of the more powerful telescopes are detecting potential Dyson Sphere civilization candidates.
They can be very hard to get since most Dyson Sphere civilizations are rather private. Fortunately since you know THE THREAD he can arrange a visit to one.
Dyson Sphere civilizations are among the highest type of any known civilization.
You can ask anything you like. Doesn't have to be astrophysics. Lol 😛
They are almost at least a billion years old. Some much older. Takes a long time for a civilization to reach that level.
Rats. So, even my young great niece won't live to see humanity achieve that. 🙁
They exist. They can just be hard to find since the Universe is so big and well mainly empty..
Likely not. A Dyson Sphere civilizations is the highest ranking I think for a civilization. I think it is what is called a type 9 civ.
Aha, a numbered ranking system. What rank type does present human civilization on earth have?
It seems there are several ranking systems for civilizations the one that uses the type 9 is kind of messy. Best to use an easier one The Kardashev System I think. Sorry for any confusion.
This, while not unexpected, is very sad. 🙁
