What is the closest notion that describes physical matter from the point of view of qm? Matter is far from being solid substance and we experience it via exchange particles. These exchange particles, if real, are energy, right?PeroK said:
Energy is a property of matter and fields, but matter and fields have other properties besides energy: momentum, angular momentum (both vector quantities) and charge, for example.

Quantum particles aren't really things and this is why I was looking for a close counterpart. It seems there is none.weirdoguy said:

Matter is decsribed by the standard model of particle physics, which is underpinned by QFT (Quantum Field Theory). Particle interactions (in particular the electromagnetic interaction) can be calculated by considering the exchange of virtual photons. Particles cannot be energy any more than particles can be momentum or can be spin. Particles have energy, momentum, charge and spin.CoolMint said:
Given that all matter is composed of quantum particles, then anything isn't really a thing! But, saying some things are things and some things aren't things is just playing with words. It's not physics.CoolMint said:
Matter and energy are closely related and can be converted into each other through various physical and chemical processes. According to Einstein's famous equation, E=mc^2, matter can be converted into energy and vice versa.
Yes, matter is a form of energy. Matter is made up of atoms, which contain particles such as protons, neutrons, and electrons. These particles have mass and therefore have energy. Additionally, the movement and interactions of these particles also contribute to the energy of matter.
Matter can be converted into energy through processes such as nuclear fission and fusion, where the nucleus of an atom is split or combined, releasing a large amount of energy. Matter can also be converted into energy through chemical reactions, such as burning fossil fuels.
Yes, energy can be converted into matter through processes such as pair production, where high-energy photons (particles of light) can create particles of matter and antimatter. However, this process requires extremely high amounts of energy and is not commonly observed in everyday life.
The understanding that matter is a form of energy has greatly impacted our understanding of the universe. It has allowed us to develop theories and models, such as the Big Bang Theory, to explain the origin and evolution of the universe. It has also led to advancements in technology, such as nuclear power, that harness the energy of matter for practical use.
