"How to dominate the universe in three easy steps …

Step 1: Harvest all of your planet's resources.

Step 2: Harvest all of your nearest star's energy.

Step 3: Harvest all the energy from all the stars in your local galaxy; then move on to another galaxy.

Congratulations! Your species now has all the elbow room it needs to grow into a universal superpower.

That's one Russian astronomer's perspective, anyway. Astrophysicist Nikolai Kardashev first proposed these three phases (called Level I, II and III) of galactic expansion — which he referred to as the three "types" of technologically advanced civilizations — in 1962 as a way to measure the energy consumption of increasingly powerful societies. Recently, a paper posted June 13 to the preprint journal arXiv.org has revived Kardashev's model and added a new, apocalyptic twist…."

That's a pretty big jump from Step 2 to 3……

One of the more interesting suggestions would be for a civilisation to harvest all the matter they can to feed a black hole and harvest the energy that escapes. And even if all stars and matter run out they might survive by uploading into a computer that running at near absolute zero temperature and running a simulation at incredibly slow speeds (only a few computations per day) powered by the Hawking radiation emitted by the black hole, we could run not only an entire civilisation, but billions or even trillions of others at the same time.

One perk of infinitesimally slow simulations is that interstellar or even intergalactic communications with other civilisations around their own black holes would seem near instantaneous.

And then even when all stars have collapsed and black holes evaporated and barring proton decay, there might be a chance that they could survive long enough on batteries by switching off all but the most minimal features and wait some 10^1500 years for Iron Stars to appear and use them as a "power renaissance"

If they were smart, they'd put a "collector" or "collectors" between the black hole and the matter source(s), to siphon it off before it goes into the black hole.

Kind of like a supercharger siphoning air, for an engine.
