F(R) Modified Gravity Tool

3D Model

F R Modified Gravity ds² = -(1-rₛ/r)dt² + dr²/(1-rₛ/r)

This equation/formula represents the Schwarzschild Metric, but within the framework to descibe the geometry of spacetime around a non-rotating, spherical mass (like a black hole). 

The shadow is the apple, gravity :D

Who (Wer): First proposed by Hans Adolph Buchdahl (1970) and made famous by Alexei Starobinsky.

What (Was): A “recipe” for gravity that changes Einstein’s rules. Instead of a simple relationship, it uses a complex functionto explain how space bends.

Where (Wo): Everywhere in the universe, but it is specific for black holes and abonomalies.

When (Wann): It is most important when looking at the very beginning of the universe (inflation) or the current era to explain why the universe is expanding so fast.

Why (Warum): To solve mysteries like Dark Energy and Dark Matter. By modifying the equation, scientists hope to explain why galaxies move and expand the way they do without needing to “invent” invisible particles.
