A BRIEF TOUR IN SPACE FROM BIG BANG TO CURVATURES

first person to realize that there are
galaxies beyond the Milky Way and
they are slowly moving away from
each other as the universe expands.
Later, scientists studied that subject
and found out that the universe is
expanding because of dark energy. As
galaxies move, their curvature moves
along with them and gravity causes the
distortion of Space Time which creates
a curvature. Thus, the curvature moves
along with the objects in space. As
light itself has no mass, even the
slightest change of gravity will affect
the wave of light passing through the
curvature. But as all the other objects
like any part of a spaceship or any
living being have a perfect mass of
their own, the effect of gravity on them
is almost 0. So, astronomers in space
