Practical physics

In the 17th century, Descartes insisted on the view of mechanical nature.  Mechanical view of nature, like a mechanical watch that was familiar at the time, thinks that natural phenomena are caused by the relationship between things and things.  In the view of mechanical nature, it was thought that local interaction is a force that works naturally. In fact, Newton's universal gravitation was criticized by scientists in France and Germany because it was a force working between distant substances. Universal gravitation was nonlocal interaction.

Nonlocal interaction can be transmitted instantaneously even between distant substances. Nonlocal interaction requires no medium like space. In modern physics, the propagation of electromagnetic waves, light, gravity is considered space as a medium.   Space is used as a concept to replace nonlocal interaction. However, this space is the concept that relativity is brought from Riemannian geometry. Modern physics treats space as naturally existing existence. When, where, and who proved the existence of space?

Space is a concept that has come to be used in physics without being proved. Gravity is explained as bending of space. However, nobody can bend the space. If we can bend the space, we can generate gravity and antigravity will be possible as well. The reason why gravity can not be controlled is because the space is fictitious. Modern physics has a fundamental mistake.

Newton's gravitation is also strange. It has the same gravity of outer space and gravity on Earth, but it is not proven.  At the end of the 18 th century, Cavendish's experiments are said to have proved that mass produces gravity. However, in the mid-nineteenth century Faraday discovered lead was diamagnetic. Mass does not produce gravity.

Gravity has not been proved yet. Explanation of gravity by relativity theory is explained by the concept of space that is not a thing. If we can explain gravity with things, we should be able to control gravity. Not only space. Wave functions also do not exist. The fact that quantum mechanics seems to be successful is due to the incorporation of classical statistical mechanics. Quantum mechanics can not explain the details of nuclei. If we can explain the atomic mechanism, we should be able to realize low temperature nuclear fusion.

Space is not a thing. Quantum is not a thing. String is not a thing. Mathematics is not a thing. Modern science and physics are far out of the methodology claimed by Descartes. As a critical thinker, against the mainstream science, we must be aware of scientific methodologies. Practical physics is our goal.
