Yes, we live in a matrix, but this matrix is one and only
Stephen Wolfram is to every scientist in the world what Black & Decker founders Frederick and Henry Stanley are to every craftsman on the planet. Stephen’s company has been supplying countless powerful computational and mathematical tools for a third of a century.
So when he takes it upon himself to reinvent physics from scratch, the occasional faint voice about physics having been stagnant for a hundred years takes on weight.
According to Stephen’s team, the Universe is based on iterations of the simplest calculation rules, like the game “Life”. So far, these rules look abstract but their repeated (repeated A LOT of times) application generates all known physical phenomena, laws, and entities.
The total possible number of such rules, depending on configuration and complexity, ranges from tens to hundreds of thousands.
To verify the theory as a whole would require as much computational work as nature itself produces. There are no shortcuts. But important features of physics manifest themselves without us recreating the universe in our computers.
It is possible that specific aspects of our universe, such as the dimensionality of space, the masses and charges of particles, could be rediscovered at the tip of a pen.
Traditional approaches to physics tend to study some aspects of the physical world but ignore or idealize other parts. There are inevitably close connections between all aspects of physics in Wolfram’s models. The result will be a large number of new concrete predictions about the universe.
There is no place in this theory for the familiar concepts of space, matter, and time. There is no concept of “empty space” in which “matter” resides. Instead, space itself is a dynamic construct, created and maintained by constant updating events in the hypergraph.
In essence, time is a computational process. Its flow reflects the execution of computation. It is noteworthy that this type of time flow is necessary to maintain the structure of this type of space.
Contrary to Einstein’s views, time has a completely different character than space. For example, the relativistic phenomenon of slowing down time in fast motion remains valid and has a much more intuitive explanation.
Atoms as such do not exist; they are the result of calculations on some grid of nodes. If they move, they recreate themselves in a new place, like circles on water. And this requires computing power. Computational power is also needed to “recalculate itself” at all new points in time. And that power is limited! So either slow motion and frequent time recalculation, or fast motion and low time clock rate.
The retelling of events takes place, as it is now customary to say, in a decentralized way. In one of his interviews, Stephen even compares this aspect to blockchain. Time is not unified, but causal relationships are strictly observed. Just like the Bitcoin network.
The computational grid is VERY dense — God has an awesome supercomputer.
If we count each element as a cell of the human body, then it turns out that EVERY ELECTRON consists of a trillion planets, each with as many people living on them as on Earth!
The theory promises many more interesting conclusions.
So, yes, we live in a matrix, but this matrix is one and only. There can be no others, and it cannot have external masters. There can be nothing at all, in essence, except this matrix of all possible rules, which generates the world, a part of which we see and realize.
