Origin of Universe

What is the big bang theory?

• A theory that states that the universe started in a large mass and then imploded to form everything.

• A theory that states that the universe was there, will be and is there. Is homogeneous and isotropic.

• A theory that states that the universe is slowly coming back to a center.

• A theory that states that the universe started in a small mass and then expanded, the expansion cooled down the temperature and that resulted in the formation of matter, energy, space and time.

According to the big bang theory, the universe began as an explosion and is still expanding. This theory is supported by observations that the stellar spectra of distant galaxies show a - (hint: which one is moving away?)

• a shift toward the yellow end of the spectrum

• a shift toward the white end of the spectrum
