Big Think explains Matrioshka Brains, theoretical megastructures that could harness the power of stars: the ultimate computer. Here is how to build one if you want to get started.

How would you, a superpower civilization that ranks high on the Kardashev scale, use such a computer, which could conceivably have all the power of the Sun at its disposal? Among science fiction aficionados, uses of this hypothetical super-tool, a class B stellar engine, could range from uploading human minds into virtual reality to changing the structure of the universe, as imagined author Charles Stross. The computers could also be used to simulate reality, potentially creating a whole alternate universe. This, of course, leads to the question - how real is our current universe?
