Discussion Overview

The discussion centers on the nature of photons, specifically whether they have mass or are solely energy. It also explores the concept of energy-mass conversion and the nature of antimatter, with a request for explanations suitable for beginners.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether photons have mass or if they are only energy, and whether energy can be converted to mass similarly to how mass is converted into energy in nuclear reactions.
  • Another participant references the concept of energy-mass conversion via E=mc^2, suggesting that energy can indeed be converted to mass.
  • There is a mention of antimatter being similar to matter but with opposite charges, and that when matter and antimatter meet, they annihilate and produce gamma ray photons.
  • It is noted that antimatter particles have equal masses to their matter counterparts but will only annihilate if their quantum numbers are equal.
  • A participant expresses confusion over the term "cre8d" used in the initial post.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the nature of photons, as the initial question remains open and is met with varying responses. The discussion includes both supportive and clarifying statements regarding energy-mass conversion and antimatter, but no definitive agreement is established.

Contextual Notes

The discussion includes assumptions about the definitions of mass and energy, as well as the conditions under which energy can be converted to mass. The nuances of quantum numbers in relation to particle annihilation are also mentioned but not fully explored.

Do photons have mass or are they only energy?
And is it possible to convert energy to mass like mass is converted into energy in a nuclear reaction?
I read in Dan Brown's "Angels and Demons" that CERN has cre8d antimatter, but what exactly is it? Please answer in terms that a noob can understand!

cre8d?...

energy is converted to mass and the other way around via E=mc^2
antimatter is exactly like matter in every respect but if antimatter and matter meet they will annilate and release gamma ray photons

Antimatter particles have opposite charges, but equal masses as their normal-matter counter-parts. The two particles will only annihilate though, if their quantum numbers are equal.
