    Energy Mass
AI Thread Summary
In pair production, energy is converted into equal amounts of matter and antimatter to comply with conservation laws, including charge, baryon number, lepton number, energy, and momentum. These laws are fundamental to the universe and are experimentally verified. The discussion touches on the philosophical aspect of why the universe adheres to these specific laws and symmetries, which remains unanswered by science. Noether's Theorem links conservation laws to the symmetries of the universe, but it ultimately leads back to the question of why these symmetries exist. The conversation emphasizes that the adherence to these laws is simply a characteristic of our universe.

Why is it that when energy is converted into mass we must make equal amounts of anti matter as matter during pair production?

Are you aware of the various conservation laws that have to be obeyed, or are you asking why these conservation laws must be obeyed?
 
Hi, I'm aware that charge, baryon number, lepton number, energy and momentum must be conserved. Yeah I should have asked why these laws must be obeyed.

It is an experimental fact that the universe we live in obeys these laws. As for why we live in a universe that obeys these laws and not some other laws... that's not something that science can answer.

(Moving beyond a B-level answer: you could google for "Noether's Theorem" and take a look at http://math.ucr.edu/home/baez/noether.html to see how conservation laws follow from the symmetries of our universe. But that just moves the "Why?" question around - why do we live in a universe with these particular symmetries and not some others? Sooner or later it comes down to "because that's how it is")

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
