An article on the basic concepts that follow the idea that information is the real substance of the Universe.
This is part six of the Information Universe series. See the link for part one.
There are a number of basic concepts that come from the Information Universe when it is applied to know principles of physics. These basic concepts not only provide a starting point to a formal Information Universe but they actually salve some problems that have plagued physics for many years. Among other things these basic concepts provide a manner of unifying quantum mechanics and General Relativity.
The first of the two most basic concepts that come from the Information Universe is that rather than be a continual coordinate system that it is actually quantized. Put another way space what consists of pixels like those on a computer screen the unit of this pixilation comes from quantum mechanics and it is call Planck length (1.616199 × 10-35 m). In Quantum Mechanics Planck length is the shortest possible measurable length in the Information Universe Planck length smallest possible unit of space forming a pixel. This pixilation has the side affect of unifying Quantum mechanics and General Relativity. While it does not produce a graviton it does divide space into discrete units and since General Relativity depicts gravity as a warping of space-time around a mass this would provide a way of bringing gravity into the quantum world.
The second the two most basic concepts that come from the Information Universe is that time is also quantized. Once again from quantum mechanics provides the unit of this time pixel and it is call Planck time (5.39106 × 10−44 s). In Quantum Mechanics Planck time is the shortest possible measurable period of time and in the Information Universe Planck length smallest possible unit of time forming a pixel of time.
These two basic concepts come from the fact that if the universe is indeed a calculating information system then such pixilation would be expected since there would have to be a level below that of both space and time at which the calculations take place.
An additional basic concept of the Information Universe is that since speed of light is one Planck length per Planck time it is the fast speed that an object can travel that covers every point in space. So for an object to go faster than light it would have to skip over segments of space. However for an object to go slower than light requires it to remain in the same Planck length pixel for more than one Planck time.
The fourth basic concept is that fundamental particles such as electrons and photons occupy one Planck length pixel for any given Planck time. That is the have a diameter of 1 Planck length and thus a volume of 1 Planck volume (4.22419 × 10−105 m3). In fact this would also be the size the singularity at the center of a black hole. One of the great results of this is the elimination of infinities from the physics by eliminating objects of zero size.
These basic concepts are the starting point of an Information Universe model. From here a full Information Universe model can be produced as mention in the article on developing an Information Universe Model. They are also critical to understanding how our universe can be based on information rather than material stuff.
