What is true about the big bang

• It was an explotion of all matter and all the energy that today fill the cosmos

• Concentration of all matter and all the energy that today fill the cosmos

• it explains the creation on earth

• Expansion and cooling of matter and formation of galaxies ,planets and life

The big bang theory can not explain the origin of the universe, cuz astronomers... saw that all galaxies that fill the universe were not standing still and were constantly moving away from each other.

• Fred Hoyle

• Georges Lemaitre

Space is expanding and at very large scales its uniform

• yes

• no

The theory of relativity is about that matter and energy affect space and time

• yes

• no

“primeval atom” or “cosmic egg” expanding at the moment of the creation of the universe, which later became known as the Big Bang theory.

• no

• yes

Whatn is the Steady State theory about?

(Fred Hoyle )

• One thing is how the universe itselfs expands and another is how matter moves in expanding space

• Matter is constantly created as the universe expands

• Big Bang

  matter dilute as the universe expands

• That the matter and energy affect time and space

Is it true that: as the universe expands, the same energy is spread over more space,so the energy density decreases, therefore the wavelength of a radiation increases proportionally as the universe expands.Longer wavelenght means lower energy, the nergy of the radiation is falling.

• yes

• no

In the dark ages the entire universe was a cloud of light atoms with virtually nothing to excite them to emit light.

• yes

• no

when the universe was only ........... it was the syze of solar system,and mattwe was in the form of an extremely "hot" soup of elementary elements.
