What is the strongest, most likely prediction out of all the GUTs that is possible to measure with current (or near future) technology?
But there may not be experimental verification until centuries later.Well judging from how many theoreticians have turned into string theory I am not sure that the main motivation is a "breakthrough" that would come from an experiment... I think it's more like how attractive the whole concept and field is to them... some people love topology and geometry...
That's why I said that they don't care about the experiment. Even if the experiment proves their theory unnatural, they have contributed to a field of mathematics.But there may not be experimental verification until centuries later.
Yeah. But i think its important to have relevance also.That's why I said that they don't care about the experiment. Even if the experiment proves their theory unnatural, they have contributed to a field of mathematics.
If we would know that...Anyway, if the world is to find a GUT, where should it put its effort right now?
When my office is a mess, and I can't find something, it is futile to look for that particular thing. The only viable option is to straighten up the whole office, file everything, and hope that what I'd like to find shows up.Yeah. But i think its important to have relevance also.

yeah, but its probably not as fun as it sounds hahaWhen my office is a mess, and I can't find something, it is futile to look for that particular thing. The only viable option is to straighten up the whole office, file everything, and hope that what I'd like to find shows up.
Looking for a GUT is like that. You try everything and maybe eventually you find something interesting.
yeh, but you have to understand something essential... for each theory that is proven natural, at least another one [or several hundrends] are proved unnatural. The reason is also kind of recent, with the mainstream topic in theoretician circles being the diphoton excess that was seen at ~750GeV. Although that excess is not yet considered important and the bets are against it (I heard something like 20:1, so betting on its unimportance wouldn't return you much money), there have been several hundreds of papers trying to explain it in the last few months [the number of papers can also give you an idea of how chaotic your room looks like ]... Not all of them will be right and maybe none is going to be... So yes... it may be or it may not seem fun... but when you are clueless your only option is to search.yeah, but its probably not as fun as it sounds haha
We already have a theory of QG. It's called String Theory. And it potentially also is a GUT :PPresumably we'll get to a GUT before Quantum Gravity
So what does string theory predict for the muon lifetime? Or for any other observable? ;)We already have a theory of QG. It's called String Theory. And it potentially also is a GUT :P
yeah I mean experimentally verifying oneWe already have a theory of QG. It's called String Theory. And it potentially also is a GUT :P
