The laws of physics place no limits on progress, be it scientific, economic, cultural, or intellectual. In fact, the laws of physics require the knowledge and wealth possessed by intelligent beings in the universe to increase without limit, this knowledge and wealth becoming literally infinite by the the end of time. Intelligent life forms must inevitably expand out from their planets of origin, and convert the entire universe into a biosphere. If the laws of physics be for us, who can be against us?
