SUMMARY

The discussion centers on the concept of dimensions in the universe, specifically the classical understanding of four dimensions: three spatial dimensions and one time dimension. Participants emphasize that these dimensions are foundational to physics rather than provable entities. The conversation also touches on alternative geometrical frameworks, such as Riemannian and hyperbolic geometry, which offer different perspectives on the universe's structure. Ultimately, the dialogue highlights the philosophical implications of understanding dimensions in the context of physics.

PREREQUISITES
  • Understanding of classical physics principles
  • Familiarity with the concept of dimensions in physics
  • Basic knowledge of Riemannian geometry
  • Awareness of philosophical implications in scientific theories
NEXT STEPS
  • Research the principles of Riemannian geometry
  • Explore hyperbolic geometry and its applications in physics
  • Study the philosophical foundations of scientific theories
  • Investigate the role of dimensions in modern physics theories
USEFUL FOR

Students of physics, mathematicians, philosophers, and anyone interested in the foundational concepts of dimensions and their implications in understanding the universe.

Can anybody tell me the known dimensions and how they are proved? I still can't understand how time is proved.

Classical belief is that the universe has four dimensions, three spatial dimensions and one time dimension. It isn't a matter of proving them or not, they are merely foundations that all our approximations in physics are built upon. Don't get any idea that physics is a true or exact science in any way. I, however, would say that it is the most accurate approximation of Truth mankind has ever created. This all starts to get into philosophy though.

I myself don't really understand the other geometries, but there are all sorts of other views about the geometry of the universe, such as Riemannian geometry or hyperbolic geometry. I hope I gave you a satisfactory answer. I can't understand how you think the three spatial dimensions are proved any more than time.
