I just thought of something else , Bill.
if the expanding space is the REASON why the galaxies
are all moving away from each other then this proves that

FREE ENERGY REALLY IS POSSIBLE

not that I ever doubted that it was , except for when I
really didn't know much about physics that is , even then
I didn't really know the concept of what free energy actually meant.
actually I firmly believe that energy can be made free.
once energy has been expended to build a machine that will
continuously output energy 24/7 without the need for energy input of any type and that type of machine would be described as a free energy machine.
the machine itself cost energy but the energy that it outputs
would be free , therefore the energy that it outputs would be

free energy

simply tie a string from one of the expanding galaxies to
a spool of string that is attached to a electricity generator
on another one of the expanding galaxies.
the galaxies will expand away from each other because
the space is expanding , this will cause the spool of string
to unwind from the spool and will turn the electricity generator that will generate

FREE ENERGY

TA DAAAA !!!
now if theres anything that simply cannot be tolerated by
either real science or ( possibly )even the fantasy science cults it would be the existence of

FREE ENERGY

some might say that the free energy would only be available
until the string unwinds from the spool and that would of
course be true , but if free energy is not possible then
it should not be possible for even a short amount of time.
so either the galaxies are moving because of the initial momentum of the big bang which would be the energy input.
or
the galaxies are moving because of the expanding space
that results in zero input energy to the free energy machine.
