hold the sun in right hand, and hold the earth in the left hand, feel the attraction force?

that is gravity. what's its speed? infinite, instant.

force has direction, strength, force is instantaneous. only moving matter has limited speed.

if you wave the right hand, the earth will wave in your left hand instantly due to gravity.

when you waving the right hand, that waving force/energy follows the gravity line teleported to the left hand.

without gravity/force, there is no energy transforming. force is the carrier/Messenger/conductor of energy.

the sun does not shoot out energy/photon into space. there is no photon, no mechanism.

the sun only shares its thermal energy with matters surround.

the forces between the sun and planets are the pipelines.

namely f=G x m1m2/rr and f=Ke x q1q2/rr.

every electron on the atoms on the surface of the sun is repelled by every electron on the line of sight surface atoms on earth. Those electrons conduct light energy.

i realize now, electrostatic focre, gravity, light and em waves are all instant force, their speed is infinite in vacuum space, only transmitting within matter/medium it has limited speed.

if this is FACT, communication between stars should be almost instant, about the time light passes through our and their atmosphere.

if that's TRUE, moon landing radio transmission takes 1.5 seconds should be a lie.

think about it.

facebook science groups are pretty cool. only 90% banned me. i have good conversation over there.
