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?
 
Physics news on Phys.org
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")

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
