The Cosmological Constant and the Laws of Physics

There's a whole field called thermodynamics that says you need to extract usable useful low entropy energy from the universe in order to do work. 1997 really threw it into perspective if here is a theorem if the cosmological constant really is constant and the laws of physics as we currently understand them are correct we only have a limited amount of free energy. We can't for any given galaxy extract more than a finite Amount of Free Energy. If we cannot evade the cosmology constant then our long-term future is to end in a heat death after some finite amount of computation has been released.
