SUMMARY
The discussion explores the relationship between Archimedes' principle and relativity, questioning whether a relativistic version of Archimedes' principle exists. Participants agree that relativistic effects are negligible for Earth-bound fluids and suggest that if energy were used instead of mass in a hypothetical relativistic perfect fluid, it complicates the original question. The conversation also touches on the concept of buoyancy pressure in the context of spacetime and hydrostatic equilibrium in neutron stars.
PREREQUISITES- Understanding of Archimedes' principle
- Basic knowledge of Einstein's theory of relativity
- Familiarity with concepts of buoyancy and hydrostatic equilibrium

- Study the properties of relativistic perfect fluids
- Explore hydrostatic equilibrium in neutron stars
- Investigate the effects of spacetime on buoyancy and fluid dynamics
Physicists, students of relativity, and anyone interested in the intersection of classical mechanics and modern physics, particularly in understanding fluid dynamics in extreme conditions.

I suppose such might exist if you want to get really weird about it, but relativistic effects have essentially no bearing upon any kind of Earth-bound fluid action. How often does something at a speed approaching c fall into a bathtub?

Suppose instesd of mass we use energy and our fliud be a relativistic perfect fluid.

That sort of negates the original question, since such can't exist. I'm getting out of my depth here, so I'm going to wait for someone with a better education to respond.

wouldn' t is kinda be hard for the energy to displace the water?
then again, I'm not einstein so i dunno.- #6

gravity = archimedes principle.
the fabric of spacetime replaces the water in this pple. in the universe there is no up or down, therefore the buyoyancy pressure takes place everywhere around matter until matter becomes spherical.

One needs an analog of Archimedes' Principle to discuss hydrostatic equilibrium in the interior of a neutron star.
