SUMMARY

The forum discussion centers on the current gaps in physics knowledge and the ongoing quest for a "Theory of Everything" that unifies the four fundamental forces of nature. Participants highlight that while classical mechanics is well understood, significant research continues in quantum mechanics, relativity, and energy sources like fusion. The conversation emphasizes that many fundamental questions remain unanswered, such as the nature of consciousness, the control of gravity, and the economic feasibility of space travel. The need for physicists is projected to increase with advancements in fusion energy and other emerging technologies.

PREREQUISITES
  • Understanding of theoretical physics concepts
  • Familiarity with quantum mechanics and its implications
  • Knowledge of classical mechanics and its applications
  • Awareness of current energy challenges and fusion technology
NEXT STEPS
  • Research the latest developments in fusion energy technology
  • Explore the unresolved questions in quantum mechanics
  • Study the implications of the Theory of Everything in modern physics
  • Investigate the relationship between physics and other scientific fields, such as psychology and life sciences
USEFUL FOR

This discussion is beneficial for theoretical physicists, students of physics, energy researchers, and anyone interested in the future of scientific discovery and technological advancement.

We don't understand the Pauli Exclusion Principle at all.

We do not understand metals from first principle. The simple nearly free electron approach works ok, but refinements on it fail. We are unable to calculate band gaps from first principle.

The big cookie in physics is resolving the apparent contradictions implicit in the theories of General Relativity and Quantum Physics.

Claude.

_Apparent_ contradictions?
Are you stating that the problem is merely a paradox?

List of unsolved problems in physics

With more knowledge, this list is not getting shorter, it is getting longer as more and more questions are coming up.

Just added a few items ...
