"Quantum" matter you say? Do tell ···
- Florin_Andrei 6y agoI mean, atoms would not exist without quantum mechanics. The system is not stable - it's stabilized by quantum effects. Without QM, electrons would radiate electromagnetic radiation and would fall into the nucleus. The result would be lots of protons and not much else. The properties of solids, all chemistry - these are basically chapters in QM.
- Koshkin 6y agoTo be fair, atoms had existed long before quantum mechanics was invented. It’s a theory, and not a perfect one. Potentially even “wrong,” as it is not consistent with one of the most important classical theories, theory of gravity (somehow gravitational waves resist quantization, and the graviton still remains a fantasy).
- Florin_Andrei 6y agoEverything existed before all theories were created, duh.
- ithkuil 6y agoAnd conversely there are things that currently exist for which theories are yet to be made. And the there are things that we thought they existed because we had theories for them which we later found incomplete or utterly wrong.
- mhh__ 6y agoAll theories are wrong. Quantum Field Theory (QM+SR) is as good as it gets at the moment and we haven't been able to find fault yet. Part of the issue with gravity is that we can get to high energy interactions on earth for the other 3 forces but we cannot get anywhere near for gravity. There's very little data to guide the process forward as opposed to the revolutions of the 20th century where it was the other way around.
