In this answer, Yuttadhammo Bhikkhu wrote about various types of death (quoted below).
- Where can I find references to and more info on the various types of death that is mentioned - khaṇika-maraṇa, sammuti-maraṇa and samuccheda-maraṇa? It can be from the Pali Canon or other sources.
- Are there also other types of death? According to this source, there is also paramattha-maraṇa (ultimate death).
- Does sammuti-maraṇa refer to physical death? This source calls it "conventional death".
Any other additional info or explanation is welcomed.
The Buddha never, afaik, used a term that could be translated as "rebirth". In fact, the idea of anything being reborn goes against orthodox early Buddhist teachings. Throughout the Buddha's teachings, it is made clear that at the breakup of the body there is birth, not rebirth - as in birth of new things, not the return of anything old.
... In this life, there is what is called khaṇika-maraṇa - death of a moment. Each momentary experience is born and dies, never to arise again. At the moment of conceptual death (sammuti-maraṇa), this process of momentary birth and death continues unimpeded unless one has experienced "death by cutting off" (samuccheda-maraṇa) - i.e. of the defilements (q.v. Vism VIII.167) - in which case there is no further arising.
To put it succinctly, physical death isn't even real according to early Buddhism; it is a concept based on the artificial construct of a "being" who is "born".
(And in this comment:) New birth is related to old birth, but nothing is ever reborn.
