Discussion Overview

The discussion revolves around the question of how energy can be transformed into mass, exploring both theoretical and experimental aspects of this concept. Participants inquire about the mechanisms involved, particularly in the context of particle physics and specific phenomena such as pair production and Hawking radiation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants inquire about the large-scale transformation of energy into mass, noting that current examples are primarily from small-scale physics experiments.
  • One participant mentions electron-positron pair production as a known example of energy converting into mass, referencing external sources for further details.
  • Another participant explains that creating mass from energy involves producing a particle and its antiparticle, which must then be separated to prevent recombination.
  • Hawking radiation is introduced as a theoretical process where particle-antiparticle pairs are produced in intense gravitational fields, although it is noted that experimental proof of this process is lacking.
  • There is a question regarding the observation of photon-photon creations of particle-antiparticle pairs, with uncertainty expressed about the reading of relevant literature.
  • A participant confirms that photon pairs can indeed be created from matter, suggesting that this has been observed multiple times.

Areas of Agreement / Disagreement

Participants express uncertainty and differing interpretations regarding the mechanisms of energy-to-mass transformation, particularly concerning the observation of specific phenomena. No consensus is reached on the details of these processes or the extent of experimental evidence available.

Contextual Notes

Limitations include the lack of experimental proof for certain theoretical processes discussed, as well as varying interpretations of literature regarding particle interactions and observations.

Do you mean on a large scale? The only examples of people purposely converting energy to mass are small scale physics experiments.

Some details on electron-positron pair production can be found here: http://en.wikipedia.org/wiki/Pair_production.
 
thaaaaaaaaaaaaank you
 
To transform energy in mass one needs to create a particle and it's antiparticle from energy...then separate them before they recombine...Al68 posted the only 'observed' example I know.

In theory, Hawking radiation results from particle/antiparticle production...you can read about that in Wikipedia for an explanation...essentially an intense gravitational field separates the pair and we observe one as real and the other "disappears" beyond an event horizon..."we" don't have experimental proof of that and certainy don't know how to do it ourselves.

Hi Naty1 What I got from the article was there have not been actual photon-photon creations of particle anti particles observed but I am not to sure of my reading. DO you know have these actually occurred in cloud chambers?
