What is the strongest, most likely prediction out of all the GUTs that is possible to measure with current (or near future) technology?
ChrisVer said: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...
greswd said:But there may not be experimental verification until centuries later.
Yeah. But i think its important to have relevance also.ChrisVer said: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...greswd said:Anyway, if the world is to find a GUT, where should it put its effort right now?

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.greswd said:yeah, but its probably not as fun as it sounds haha
it can be from 0 to infinity? So I guess it should contain the measured one... (currently fighting with ambiguities in my compiler, they are for sure not good)mfb said:So what does string theory predict for the muon lifetime? Or for any other observable? ;)
yeah I mean experimentally verifying onehaushofer said:We already have a theory of QG. It's called String Theory. And it potentially also is a GUT :P
Grand Unified Theories (GUTs) aim to unify the fundamental forces of nature, namely electromagnetism, strong nuclear force, and weak nuclear force, into one single theory. It is believed that GUTs could provide a deeper understanding of the universe and its workings.
The current limitations in predicting GUTs using current technology lie in our understanding of the fundamental forces and particles of the universe. We have not yet been able to fully reconcile the theory of General Relativity (describing gravity) and Quantum Mechanics (describing the other three forces) into one cohesive theory. This is known as the Grand Unification Problem.
While there have been significant advancements in theoretical physics and experimental findings, we are still far from achieving the strongest prediction of GUTs with current technology. The Grand Unification Problem remains a major challenge in the field, and it may require advancements in technology and new discoveries to overcome it.
Some of the current experiments and technologies being used to study and predict GUTs include the Large Hadron Collider (LHC) at CERN, which is designed to search for new particles and interactions that could support GUTs. Other experiments include precision measurements of particle properties and studying the cosmic microwave background radiation for evidence of GUTs.
Continuing to research and predict GUTs with current technology is crucial for our understanding of the fundamental laws of the universe. It could potentially lead to a unified theory that explains all known physical phenomena and provides a deeper understanding of the nature of reality. It could also have practical applications, such as advancements in technology and energy production.
