each body that moving is generating EM wave

Each body that is moving is generating EM vacuum ( cavitation)


to describe cavitation please use ideal GAS model
to help You I prepared simple example
two empty balls Under Water ! ( water = EM preasure from stars )

each ball drinking energy ( inside balls we have holes ! ) water is going inside ball




IF IF EMPTY BALL WILL START VERY VERY fast rotation respect to own
axis !!! WATER ( energy will not go inside BALL )

ROTATION = photons will not able GO INSIDE BALL !!!
WATER can not WIN with F= m*V*V/ R

ROTATION = WE LOSTING MASS !!!
