So why the hot pursuit of QG while GUT unification does not look even attainable. None(AFAIK) of the QG theories seem to address this question (GUT), or am I wrong.

krash661 said:is GUT mean grand unified theory ?
i hope i do not receive a warning for spam by my post that is a question.
String theory claims that quantum gravity must emerge from a theory addressing unification.ftr said:So why the hot pursuit of QG while GUT unification does not look even attainable. None(AFAIK) of the QG theories seem to address this question (GUT), or am I wrong.
tom.stoer said:Your question is clear.
But I do not see why a certain research program should have priority. It depends on the perspective, of course. If you are interested in particle physics, then 'GUT' is more important. But if you are interested in quantum gravity (+ other interactions on top), then QG should have priority.
We do not know which research program will succeed, so most experts would agree that there should be more than one game in town ;-)
ftr said:Yes, I agree variety is good. But To my mind it sound easier and more important to UNIFY electroweak and the strong force in an unambiguous way (at least as first step). If we cannot do that, then there is a hint of either something is wrong with the formalism or the nature of these forces is not what we think it is. That might even shed some light on gravity. In another word, why not try another route, which seems to be little researched if not neglected.
PAllen said:What makes you think GUT's are little researched? They have been enormously researched and continue to be researched. Just because they are not written up in popular press doesn't mean they aren't researched.
ftr said:What I meant is that GUT is not discussed by high profile scientists or Theoretical centers. Can you cite some, I appreciate it.
mitchell porter said:No, that is too much to ask, there are too many variations. Just look at the threads in this sub-forum, there are many discussions of theories which don't fit the paradigm that I described.
GUT (Grand Unified Theory) attempts to unify three of the four fundamental forces of nature (strong nuclear, weak nuclear, and electromagnetic) into one single force. On the other hand, quantum gravity is a theoretical framework that aims to reconcile general relativity (which explains the force of gravity) with quantum mechanics (which describes the behavior of subatomic particles).
There is currently no definitive answer to this question. Some theories, such as string theory, attempt to unify GUT and quantum gravity, but they have not yet been proven or widely accepted by the scientific community.
The main challenge is that the two theories operate at vastly different scales. GUT deals with the forces at the subatomic level, while quantum gravity attempts to explain the behavior of gravity at the scale of the entire universe. Additionally, there is currently no experimental evidence or direct observations to support either theory.
If successfully unified, GUT and quantum gravity could provide a more complete and accurate understanding of the fundamental workings of the universe. It could also potentially lead to new technological advancements and advancements in our understanding of the origins of the universe.
Yes, there are ongoing research efforts and experiments being conducted to test and further develop theories of GUT and quantum gravity. These include experiments at particle accelerators, observations of cosmic microwave background radiation, and theoretical advancements in string theory and other potential unifying theories.
