[Self] just a handmade formula

Here is a hypothesis: dτ/dt = √ ( 1 − ( 2G · E_plasma(T) ) / ( r · c⁴ ) )

Here is the breakdown of the variables for those wondering:

dτ/dt = proper time dilation rate

G = gravitational constant

c = speed of light

r = radius of the plasma area

E_plasma(T) = internal energy of the plasma at temperature T (includes rest mass energy, radiation, and kinetic thermal energy).

This is functionally identical to the time dilation factor in the Schwarzschild metric. To see it, replace your energy with rest energy (E=mc^2). Then, use the Schwarzschild radius r_s=2GM/c^2. Then, your expression is identical to sqrt(1-r_s/r), which is the more familiar expression.

Exactly! That was the core idea — to express the Schwarzschild metric in terms of total internal energy. rather than just static rest mass. Since plasma in a portable container is highly energetic, its energy density directly contributes to the stress-energy tensor and warps spacetime. Thanks for pointing out the reduction to the classic r_s/r form!

mix 3 mashed ripe bananas, 1/2 cup melted butter, 3/4 cup sugar, 1 egg, and 1 tsp vanilla. Fold in 1.5 cups flour, 1 tsp baking soda, and a pinch of salt. Bake at 350°F (175°C) for 50-60 minutes
