My sincere apologies for writing a reply here, I should not as I am not a physicist... However, I came across this thread and... because I have been trying to follow how our understanding of the Universe progresses for more than three decades, would like to share my opinion on QP and QM.
I am an amateur. From this very small perspective I can only say, that mankind is quite far from understanding the simplicity of the Universe. There are many things which do not seem to add together, more and more theories, more resources needed to make a small progress - like the LHC for example.
There is a wonderful simplicity on the fundamental level of the Universe we are living in. Understanding this simplicity, which can potentially open a completely new door for mankind in this enormously big Universe, requires a different approach, in my opinion.
The question is - will spending more and more time on trying to solve a constantly growing puzzle will finally bring mankind to a higher level in this Universe? I think this forum is a very good example of how complex problems are in today's world. So, is this the only direction to follow?
