In the light of the large number of possible description for mass, to what extent do you think that scientific process has been successful in replacing old models with new models? Are all this models compatible?
There have been two important models of matter in history, which tried to explain the concepts of Matter, the molecular kinetic theory and the atomic theory of matter. Nevertheless, different scientists throughout history have as well disputed these two concepts.
The molecular kinetic concept states that all the things, all objects, all matter is made up of molecules, which consisted of small particles that vibrated. This particles speed up their vibration as they are being heated and slow down when they are being frozen. This creates a change of state between them.
Moreover, with further investigation scientists discovered that although the molecular kinetic theory was not completely wrong and that it had the basic concepts and the main idea of what matter was made up right, it wasn’t enough. It was discussed that particles wasn’t the smallest part of the matter. It stated that these particles could be further divided into extremely small atoms, which consisted of protons, neutrons and electrons.
Therefore, the kinetic theory was used as the basis to develop and find out more things. Much more concepts have opened up in the Scientifics mind but as they don’t have a lot of proofs, there are a lot of contradictions that dispute whether they are true or aren’t.
For example, the subatomic particles consist of atoms, even smaller than protons and neutrons called quarks. But then they were defined as vibrating strings. The anti-matter particles state that for every proton, neutron and electron there is another one mirroring it. The newest theory is the string theory where it is denied the first theories that the atoms are round balls, and define the atoms as strings.
All of these models will continuingly improve, or there will be assumptions for newer ones. However they are all ASSUMPTIONS so scientists will always contra arrest them until they have real proofs. In my opinion scientists have advanced in the discoveries of matter, but until they find real proofs about this it will be very difficult to move on and to think of them as reliable.
