Recognize this place?
yes you have guessed
it’s our planet , Everybody you know of,
every hopeful parent, every curious child,
every animal, every Explorer and destroyer,
the rich and the poor all live here, but Have
you ever wondered looking up in the Night
Sky, and wondering what may be out there,
welcome to cosmology classes
so the first question is, What is cosmology?
so Basically cosmology is the branch of astronomy
concerned with the studies of the origin and
evolution of the universe, from The Big Bang
until the present and onto the future, it
is a scientific study of the origin evolution
and eventual fate of the universe
Cosmology is an old term in terms of nature
but, the new subject in terms of modern science
Cosmology first began in the ancient times
when The Greek and the Babylonians started
noticing how the constellations in the sky
were moving from one place to another hello
and that was birth of cosmology
Cosmology is the study of the large scale
properties of our universe as a whole this
means that scientists and cosmologists will
look far into the past of how the universe
was born all the way to the end of how it
will die they look billions of years into
the past to the edge of the observable universe
to see how this whole universe was created
they also test modern theories in physics
to determine how it's going to die
What is the fate of our universe??
well scientists have built instruments to
test this, for example ESA and NASA’s Hubble
Space Telescope may be known for its incredible
images but did you know that its core mission
was Cosmo logical research while we still
have a long way to go Hubble has greatly improved
our understanding of dark energy and the nature
of our expanding universe another great discovery
came from NASA’s Wilkinson microwave Anisotropy
which mapped tiny fluctuations in our cosmic
microwave background or CMB for short that
ancient light leftover from our early universe
and it discovered that
familiar atoms only make up 4.6% of our universe and
dark matter makes up 24%
this means that everything we
see accounts for less than 5% of our universe
