8C20.90 - Dark Energy

Code Number:
Demo Title:
Dark Energy
Dark Energy
Area of Study:
Sliding capacitor, Electrometer, 67 1/2 volt battery.

The demonstration shows that when the charged capacitor plates are moved apart the voltage rises.  This is an analog of the theory the dark energy is increasing as the universe expands.
