General and Special Relativity assumes C is a constant. It is not. GR is a thought experiment and not much more.

Here's a more concise rundown of key experiments validating General Relativity:

1919 Solar Eclipse -
Light from stars was seen bending around the Sun during an eclipse, confirming gravitational lensing.

Mercury's Orbit -
Explained the extra precession not accounted for by Newton's laws.

Hafele-Keating -
Atomic clocks in airplanes confirmed time dilation due to gravity and speed.

Gravitational Redshift -
Showed light loses energy climbing out of a gravitational well.

LIGO's Gravitational Waves -
Detected waves from black hole mergers, proving their existence.

Shapiro Delay -
Radar signals to planets showed light slows near massive objects.

Binary Pulsar -
Energy loss in binary systems matched predictions for gravitational wave emission.

Galaxy Cluster Lensing -
Light bending by clusters confirms spacetime curvature.

Gravity Probe B -
Measured frame-dragging and geodetic effects around Earth.

Cassini's Radio Signals -
Proved how gravity affects light's path near the Sun.
