Laws of Physics
From Simulism
The laws of physics impact the idea of simulation in a variety of ways. There are several notable speculations regarding cosmology and simulation that are curious to ponder.
The known Universe has approximately 1080 atoms in it, organized with approximately 1057 atoms in a star, about 1011 stars in a galaxy, and about 1011 galaxies. These numbers, although "astronomical", pale in comparison to the exponential growth rate of Moore's law. Were Moore's law to continue at the present rate, every atom in the universe would be be tangled up inside a computer after a few short millenia. Clearly, Moore's law can't continue; however, this also begs the question: why is the Universe "so small" in comparison to Moore's law? Is it because the Universe we live in is simulated, and that this is the size of the simulation space?
There is another notable speculation with regards to cosmology. We can note that the universe is about 15 billion years old, the Earth is about 4.5 billion years old; that life has existed on Earth for 3.5 billion years, and that dinosaurs evolved more than hundreds of millions of years ago. There is no particular law of physics that says that this couldn't have happened earlier: Humans might have evolved hundreds of millions of years ago, instead of just recently. In this case, one might expect that the post-human singularity has already happened. Perhaps it has already happened elsewhere, on some other planet, elsewhere in the universe. If so, then where are these Jupiter brains? They are not obviously visible in astronomical photographs. On the other hand, one of the great mysteries of cosmology is that a very large portion of the known universe consists of "dark matter". Is it possible that super-human intelligences have already come into being, many billions of years ago, and have recruited large chunks of the universe for use as a computer? Arew we possibly witnessing this as the form of "dark matter", or possibly even "dark energy"?
