Undergrad Is "Pair Production" a creation event?

Click For Summary
SUMMARY

The discussion centers on the concept of "pair production" as a creation event in physics. One participant defines pair production as the conversion of massless particles, such as photons, into massive particles, like electron-positron pairs, emphasizing that this process adheres to energy and momentum conservation laws. The opposing viewpoint argues that all creation events in physics involve some form of conversion, challenging the notion of creation from nothing. Ultimately, the conversation concludes that the debate is more about semantics than scientific resolution.

PREREQUISITES
  • Understanding of pair production in particle physics
  • Knowledge of energy conservation laws
  • Familiarity with particle types: bosons and fermions
  • Basic concepts of particle annihilation
NEXT STEPS
  • Research the principles of quantum field theory
  • Study the mechanisms of particle-antiparticle creation
  • Explore the implications of energy-matter conversion in physics
  • Investigate other creation events in cosmology and their definitions
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the philosophical implications of creation events in the universe.

Okay, please forgive what seems to be a religious debate cause I assure you it is not. I am merely seeking your opinion on an exchange.

Now, I said that pair production is an "example of creation that requires no conscious act". To this example my opponent said the following:

“Matter creation is the process inverse to particle annihilation. It is the COVERSION of massless particles into one or more massive particles. This process is the time reversal of annihilation. Since all known massless particles are bosons and the most familiar massive particles are fermions, usually what is considered is the process which converts two bosons (e.g. photons) into two fermions (e.g., an electron–positron pair). This process is known as pair production”
"It is a natural occurrence, it can’t occur unless the conditions are right, and it works on Energy conservation laws as well as momentum conservation laws. "
" It can’t occur in empty space, it can’t occur when the conditions are provided."

He argues that this is an example of a conversion of energy to matter (even though I've already been explained here that energy is not a thing but a property, bear with me ). But isn't that the case everywhere? Things merely change shape, they don't just appear out of "nothing".

Are there other types of "creation" events in physics? As far as I remember all of them refer to some sort of conversion.

This is not a scientific topic. It is just a semantic argument about the definition of the word "creation". Your definition allows creation from something his definition requires creation from nothing.

This cannot be resolved by science. It can only be resolved by agreement to use the same dictionary.

Thread closed.

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
