They are uncaused because of how the theory is formulated, and it's formulated this way to accommodate cornerstone physical principles. They are random because they do not have a deterministic cause, and would be paradoxical otherwise. Giving them ONE cause is like choosing a starting point on a...

It can depend of your starting point. Is it the uncertainty principle? Is it the zero point energy of oscillators? Is it the impossibility of having zero temperature? Or perhaps quantum corrections to vacuum diagrams? Depends on what you define to be the most fundamental of these things. The...

I really just wanted someone with enough knowledge in alternative gravity theories/GUTs to give their contribution to a simple question. I totally agree than peripherical details can be helpful, just not here. I should have formulated it as "IF, and only IF, you know of a theory where tetrads...

Assuming what I did and what I did not before asking a wider group of people is extremely presumptuos. Especially given the fact that neither my advisor, nor you, clearly knew the answer to my question. The difference is you're [Mild insult deleted by the Mentors]. The closest answer was...

Advisors and professors are not omniscent. The broader audience the higher the chance of an interesting response, but I'm now reconsidering such conclusion

Unfortunately there's no "tetrad fields in modern theories" list, and I can't go read every publication with "tetrad" in it. So no, studying something for something's sake is different from finding "all the bibliography" where it appears in modern theories

I'm a graduate theoretical physics student at the (almost) end of his master's degree with a fairly varied curriculum, as I attended both QFT (and sub-courses on qed qcd etc) and GR courses. However in my latest intro to quantum gravity classes I familiarised with tetrads and, after a lot of...
