The
____________________
is
the
brand
of
Physics
that
studies
the
Universe
.
In
its
beginings
,
it
was
told
that
the

was
the
centre
of
the
Universe
.
That
model
was
called
____________________
and
it
was
believed
to
be
true
until
the
16th
century
when
Nicholas
Copernicus
created
the
____________________
model
,
which
says
that
the
____________________
is
the
centre
of
the
Universe
.
Nowadays
,
we
consider
that
Copernicus'
theory
is
only
partly
true
as
the
Sun
is
only
the
centre
of
its
system
but
not
the
centre
of
the
whole
Universe
.
The
Solar
System
belongs
to
a
galaxy
