Why the process of recombination is called re combination?

Click For Summary

Discussion Overview

The discussion revolves around the terminology of the process known as "recombination," specifically questioning the use of the prefix "re." Participants explore the implications of this terminology in the context of atomic formation in the early universe.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the use of "re" in "recombination," asking if there was a prior combination process that justifies this terminology.
  • Another participant suggests that the term "recombination" is a misnomer, implying that the prefix may not be appropriate.
  • A different participant defines recombination as the process that occurs when the universe cools enough for electrically neutral hydrogen atoms to form.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of the term "recombination," indicating that there is no consensus on whether the prefix "re" is justified.

Why the process of recombination is called "re"combination?

The process in which the nucleus and electrons combined to form neutral atoms at early times is called recombination. But why it is added an "re" to "combination"? Is there any combination process before this process?
Thx!

i used to go out with a misnomer :redface:
 


Recombination is defined as when the universe cooled sufficient to permit electrically neutral hydrogen atoms to form.
