Testing G Speed

First effort influence
casting general doubt
Contending differently first
analyzing key role without
Illustration imagine blink
general phenomenon relativity
Gravity bending light
heightened acceleration negativity
Distinct solar eclipse
nonexistent instant waves
Conducted experiment distortion
predictable theory behaves
Cosmic dark matter
timing light speed
Measurement precision principle
bending radio waves precede
Unsettled constant super-string
quantum theory quest
Speed of gravity?
Extra-dimensional theoretical test
