2. The universe is made up of millions
of Galaxies.
A galaxy is a swarm of billions
of stars, clouds and dust
rotating around a central
point.

3. • The Galaxy is 100,000 light-years
across, but only a few thousand light-
years thick.
• As we start out towards the next step, we
see other galaxies like the Milky Way
begin to appear. Compared to stars in
the Milky Way, galaxies are packed
together much more closely, and
collisions between galaxies are much
more common. The Andromeda Galaxy,
the nearest galaxy to the Milky Way, is
2.5 million light-years away and on a
collision course for Earth. Don't panic,
though, as the collision won't happen for
another 3 billion years

4. • At a size scale not much larger
than our last, we see that the
galaxies are clumped together.
These galaxy clusters typically
have hundreds of galaxies and
are millions of light years across.
Galaxies orbit around the center
of their clusters,These groups of
galaxy clusters are
called superclusters. A
supercluster may contain
hundreds of thousands of galaxies

5. Hubble's Law
Hubble's Law describes the expansion of the universe mathematically:

The Age of the Universe
• Imagine a galaxy which flies out from the big bang
at the speed of light, The distance it traveled
denoted as
d=vt

6.  Big Bang Theory
 Steady State Theory
 Creation Theory

8. According to the theory, the Universe was created sometime between 10
billion and 20 billion years ago from a cosmic expansion that continues to
spread matter in all directions.

11. •The universe has always been as
it is today
•New matter is always being
produced
•The universe is continuously
contracting and expanding.

12. •God created the Heavens and
the Earth.
•Adam and Eve
•Religion

13. How the planets created according to the
Theories
• An important necessity for the appearance of
life is heavy elements. Since only hydrogen
and Helium gas were formed during the big
bang

14. • Stars use light elements like
Hydrogen and Helium as their
fuel. Like nuclear bombs, they use
the power of the atom for energy
• This process is
called fission. In a star, the
energy comes from
converting the light elements
into heavier elements. This
process is called fusion. All
of the material in the
universe heavier than
Hydrogen and Helium were
made by fusion in a star.
Stars

15. • The heavier elements were made
in supernovae, Supernovae are extremely
bright and extremely hot
• This is where the heaviest elements in the
universe are made.
• All of the material needed to make rocky
planets was made in stars, and some of it was
made in supernovae. This means that planets
couldn't exist until there had been enough time
for a star to completely go through its life cycle
and become a supernova
Planets

16. • The material would then be
ejected back into space, and
would form a new star,
possibly with planets. It also
means that everything in the
world, including you, came
from a star. As the astronomer
Carl Sagan said, "We are star
stuff."

17. • A bigger
planet has
been created
by collision
small rocks
and planets

18. • The Sun and the Earth formed
about four and a half billion years
ago, when our long-lived
astronomer was 37 "Milky Way
years" old. A solar system forms
relatively quickly, and ours
probably took only about 100
million years. The Sun and the
planets formed from a cloud of
sparse gas in the

19. The end of the Universe
(or) it’s beginning
Looking back over the scales of the universe and seeing
humanity's role, unimaginably small in both space and time,
one might wonder whether science has painted a bleak,
depressing, and hopeless picture for humanity. Some would
say so, while others find comfort in the majesty and
grandeur of the universe, and the possibilities that the future
might bring. For now, the future of humanity in this universe,
as chaotic and vast as it is, remains uncertain
