In a recent article put out by Forbes magazine, we read that the Universe, as we know it, has a fundamental flaw staring us right in the face which is letting us know that our knowledge is incomplete.
We do know that there are four fundamental forces: gravity and electromagnetism are just two of the four fundamental forces of nature, specifically two that you can observe every day. What are the other two, and how do they affect you if you can't see them?
The remaining two forces work at the atomic level, which we never feel, despite being made of atoms. The strong force holds the nucleus together. Lastly, the weak force is responsible for radioactive decay, specifically, beta decay where a neutron within the nucleus changes into a proton and an electron, which is ejected from the nucleus.
Without these fundamental forces, you and all the other matter in the universe would fall apart and float away. Let's look at each fundamental force, what each does, how it was discovered and how it relates to the others.
The problem for us is that the four fundamental forces are described by two different and mutually incompatible frameworks: General Relativity for gravitation, and Quantum Field Theory for the electromagnetic and nuclear forces. Einstein's theory on its own is just fine, describing how matter-and-energy relate to the curvature of space-and-time.
Quantum field theories on their own are fine as well, describing how particles interact and experience forces. But where gravitational fields are strongest, and on the smallest of scales, we have no way of describing nature. But the basic idea, that fundamental quantum bits (or qbits) possess temperature and information, and that everything else about gravitation, including perhaps even space and time, can be derived from that, is too big to ignore.
Its an electric universe as Tesla would say... that is why electromagnetism is one of those fundamental forces. Its what really keeps things in place and in that knowledge, we know this from discovering how to create gravity in space in an enclosed space.
In space, it is possible to create "artificial gravity" by spinning your spacecraft or space station. When the station spins, centrifugal force acts to pull the inhabitants to the outside. This process could be used to simulate gravity. A kind of illusion. And, even more fascinating is that illusion is defined by another kind of illusion - Gravitons which are theoretical light particles. Such light particles are thought to carry the electromagnetic force. Gravity is very weak compared to the other forces in the universe, so its force-carrying particles are very difficult to detect. Nobody has ever detected a graviton, and the only way that we know of them is to produce them by tricking them into having mass.
We know that in order to do that, we have to produce gravity uniformly over a surface and that surface would have to have a lot of mass! How to achieve that? Again, its all about generating an illusion. Basically, all you need is to feel the mass which is generated by centrifugal 'pseudo' force.
An example given... a brick has the same mass on the surface of the earth as it does in deep space. Weight is the force that something feels due to gravity: so the brick would have a much larger weight near the earth's surface than it does in deep space.
Here or there, centrifugal force is a pseudo force... a kind of illusion when you think about it as we are yet left only with information to determine what is the weight of anything if not for gravity and electromagnetism holding everything in place. The weight of something is felt but is it really. Its information coming at us and in that packet of information is data which determines how we will react to such data which is controlled by electromagnetism. We just don't know who, as 'men' of man's science, is controlling that data and its conduit.
What we can observe, in order to increase mass using the weight of what we think we know as we feel it in the place where we are, is that weight can be controlled by the speed of applied energy to the already theoretical force known as electromagnetism. Thus, the further away from earth, the more spin - acceleration upon that information 'weight' is needed to produce the kind of generated mass necessary for uniform gravity spread over a surface. So we think, and so we think we feel it.
The illusion is just that... information on the quantum level applies differently in the place where you are in comparison to the place where you are not but both are useful in the socio-quantum 'social' imagination.
