The document discusses the evolution of the universe from the Big Bang theory. It describes the Big Bang theory as the most accepted explanation for the origin and early development of the universe. It states that before the Big Bang, there was nothing - no time, no matter. After the Big Bang, the universe began rapidly expanding from an extremely dense and hot state. As it expanded, the early universe progressed through different eras from radiation to the formation of atoms, galaxies, and stars. The expansion of the universe continues today.

3. Universe
• The universe is the set of all that has physical
existence in the Earth and outside her.

4. Theories
Several theories about the origin of the
universe.
• Steady State Theory: The universe never had
an origin, it always existed.
• Inflationary Theory: Is a set of proposals that
explain from the big bang the rapid expansion
that took place in the first moments until
today.

5. • Oscillating Theory: Would oscillate between a
great explosion and a great implosion.
• Multiverse Theory: In addition to our universe,
there will be undiscovered.
• Creationist (religious) Theory: The universe
created by god.
• Big Bang Theory: A bigger explosion.

6. Big Bang
This theory is the most accepted because there
are proof.
Before explosion, there was nothing, no time, no
matter…
Is still unknown is the caused, that happened at
one point very concrete.

7. Universe development
After of the Big Bang, the universe begings to
spand.

8. The eras
Radiation era
Phases:
Matery era Atoms
Galaxys

9. The theory of expanding
The theory explain that:
Matter and antimatter joins
Causing explosions

10. The beging of the end
The universe after expanding its stop to spand.

11. After the Big Bang, what happened?
• At the time of the Big Bang, the 4
fundamental forces of nature: gravitation,
strong force, electromagnetism, weak
force.
• Hydrogen, Litium and Helium

12. Then the radiation and matter that cover the
entire universe are separated, which is
defined as the decoupling. Then galaxies,
stars and planets appear.

13. Arno Allan Penzias and Robert
Woodrow Wilson
A curious fact is that in 1965, these two
physicists detected a radiation in the radio
wavelengths, which correspond to an
extremely low temperature

14. Conclusion of the after of the Big
Bang
• The pieces of matter generated in the
explosion cooled down.
• A part of that matter create 100,000
million galaxies that make up the universe.
• The other part is called dark matter and
its nature is a mystery today for scientists.
