fact: pressure causes "heat".
fact: heat doesn't exist. It's just things disintegrating radially (flying apart outward as a field)
Two pieces in mutual isopressure get "hot" inside and the "material" radiates out as a
piece field (pieces SO "tiny" they can ghost out through the object as its attractive field).
fact: "space" is a fluid of such pieces (the Blood of the World).
The piece field that radiated out due to internal "heat" caused by mutual isopressure
also ghosts through the disparate pieces that "space" is. They rush inward replacing what ghosted out.
"Space", "light", and "electricity" are all just pieces of space that supply this process of turnover into field.
