Could the universe be a giant computer?

According to MIT professor Seth Lloyd, the answer is yes. We could be living in the kind of digital world depicted in The Matrix, and not even know it.

How much data can fit in the universe?

Lloyd concluded that our universe could fit a whopping 1090 bits, or a trillion trillion trillion trillion trillion trillion trillion megabits.

Is your brain a quantum computer?

This means that your body is not just a biochemical system: it’s also a macroscopic quantum system. Your brain is not just a bioelectric and biochemical computer, but also a quantum computer. The cells of your body, and the neurons and networks of neurons of your brain, are entangled with each other.

Can you simulate the universe with a quantum computer?

Lloyd also postulates that the Universe can be fully simulated using a quantum computer; however, in the absence of a theory of quantum gravity, such a simulation is not yet possible. “Particles not only collide, they compute.”

How many bytes can the universe store?

One can obtain a rough upper limit for the maximum number of bits of information the universe could possibly hold as being somewhere around 10^122 to 10^124 depending on which parameters you feed in. We know the entropy of a black hole is related to its surface area divided by the Planck length.

How much memory would it take to simulate the world?

If we simulated solely at the atomic level, at least 100 bits would be required to describe each atom. According to web searches, Earth is estimated to have about 1.33*1050 atoms. Totaling it out, that would require about 1.5442 gigabytes of RAM.

How many states are in the universe?

The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don’t move much.

Is the universe a computer Weinberg?

‘ “In the study of anything outside human affairs, including the study of complexity, it is only simplicity that can be interesting.” This is Steven Weinberg’s credo [“Is the Universe a Computer?” NYR, October 24, 2002]. …
