Part 7/10:
Compelling theories posit that if gravity were to propagate through additional dimensions, it could explain its weakness. One potential scenario posits that gravity’s energy is absorbed through oscillations within these hidden dimensions, ultimately causing it to behave weaker than other forces on larger scales.
Revisiting the Cavendish Experiment
To investigate these compact dimensions, modern physics revisits the original Cavendish experiment, an ingenious system devised to measure gravitational forces with remarkable precision. Cavendish's device consisted of a torsion pendulum with lead balls, sensitive enough to capture the minuscule gravitational interactions that eluded simpler apparatus.
