The scalar fields are amazing. What are the electrical signals works like this: with the further away you go the stronger the signal. This is crazy but once the scalar field is established the field can become stronger. The further apart you have received from the transmitter.
Echo’s assumption is: Because scalar absorbs the ether (the energy) from the environment and when they get further apart so they can get more energy from the environment that’s why the light is brighter.
Storing the energy from the environment this is one reason why John was so excited when he’s developing scalar that’s because scalar is a natural field and it’s a healthy field.
