At Big Questions Online Andrew Briggs ponders the ultimate nature of reality and wonders whether, at bottom, everything is information. It's an intriguing question. What is the fundamental reality that makes up our world and ourselves?
Generations of scientists have assumed it was matter made of atoms, but as we learn more about the atom it seems that the appearance of materiality that the world presents to our senses is in fact something of an illusion, a trick played on our senses by something even more fundamental than matter. After all, when we dissect an atom down to its tiniest constituents we find that they're really just ghostly manifestations of energy (whatever that is). They seem to be nothing more substantial than a mathematical abstraction.
We find that these subatomic particles don't play by the same rules that macroscopic material objects play by. Subatomic particles can be in two different places simultaneously, a phenomenon called superposition, and they can also affect each other even though they're at opposite ends of the universe moving away from each other at the speed of light, a bizarre phenomenon called quantum entanglement.
If matter turns out not to be the fundamental reality what would be? If, as Briggs suggests, it's information then that suggests an even more basic reality, i.e. mind, that underlies everything. That would really upset the metaphysical applecart because if mind is the fundamental reality then we're but a few short steps, philosophically speaking, from the conclusion that God, or something very much like God, exists.
