SUMMARY

The discussion explores the conceptual similarities between gravitational forces, as described by the Ricci tensor in general relativity, and the surface tension forces that maintain the structure of a soap bubble. Participants debate whether these two phenomena are fundamentally comparable or entirely distinct. Key references include the concept of "minimal surface" and the Ricci tensor's role in preventing the universe's collapse. The conversation highlights the complexity of understanding these physical principles, especially for beginners.

PREREQUISITES
  • Understanding of general relativity and the Ricci tensor
  • Basic knowledge of surface tension and its effects on physical structures
  • Familiarity with the concept of minimal surfaces in mathematics
  • Ability to interpret scientific papers, such as those found on arXiv
NEXT STEPS
  • Research "Ricci tensor in general relativity" for foundational knowledge
  • Explore "surface tension in fluid dynamics" to understand its principles
  • Study "minimal surfaces" in mathematics for a deeper grasp of the concept
  • Read scientific papers on the relationship between gravity and surface tension
USEFUL FOR

This discussion is beneficial for physics students, researchers in general relativity, and anyone interested in the comparative study of gravitational and surface tension forces.

forces (Ricci tensor etc.) which prevent universe from collapsing and
the tensorial forces of surface tensions which prevent a soap bubble from collapsing?

Are these two phenomena absolutely incomparable?
Could someone explain in simple words why?
I'm new, and a student in quest for knowledge
Thank you, everybody

Thank you Sir, I downloaded the suggested file, but on the face of it it'll take me months (if ever) to digest it.

Could anyone be so kind and anticipate the answer:
Are the two systems absolutely incomparable?why?

My naive view of the problem is that
soapbubble and universe are like a fully spherical vault ( a vault is semi spherical, an arch is semicircular), in which every element is a Keystone
and surface tension and gravitation prevent collapse.

I realize this is silly and not true. My question is " untrue, silly but impossible in principle?"
