Discussion Overview

The discussion revolves around the effects of using lasers or blasters to create holes in metal, specifically questioning whether any matter from the metal is completely eliminated from the universe during the process. The scope includes conceptual reasoning and technical explanations related to material transformation and conservation of mass.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants question whether the matter from the metal is completely eliminated from the universe when a hole is made using a blaster or laser.
  • One participant refers to laser ablation as a relevant process to consider in this context.
  • Another participant asserts that the matter is not eliminated, suggesting that the metal behaves similarly to water when boiled, where vaporization occurs but matter is not lost from the universe.
  • A participant challenges the notion of something "disappearing from this universe," implying that all matter undergoes transformation rather than elimination.

Areas of Agreement / Disagreement

Participants express disagreement regarding the concept of matter elimination, with some asserting that matter is transformed rather than eliminated, while others seek clarification on the implications of the original question.

Contextual Notes

The discussion includes assumptions about the definitions of "elimination" and "disappear," which remain unresolved. The nature of matter transformation during the processes discussed is also not fully explored.

When blaster or laser is used to make a hole in a piece of metal is any of the matter of the metal completely eliminated from the universe?

Great. Explanation?

Where does the water in a pan go when you boil it dry? That's what happens to the metal - the difference is that just that some metal vapors burn but water vapor doesn't.

What to explain? Do you know any process that will make something to "dissapear from this universe"? Whatever that means.
