of their curvature also increases and
decreases time to time. Time is a
function of light so when light will
cross a big curvature, time will run
slow and when light will cross a
relatively small curvature, time will
run relatively fast. These curvatures of
different objects in space are moving.
Planets are orbiting stars and stars are
orbiting the core of different galaxies.
Galaxies are spinning in a fixed pace.
Some objects in space are fixed.
Someone might say that „they seem to
move because the Earth is moving but
actually they are in a fixed place.‟ But
accept all those concepts, all the fixed
and moving objects in space are
moving in a different way. They are
moving because of dark energy. From
