Theories on the Origin of the 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.

The ​ (a)   claims the universe has always been the same.

• Steady State Theory

• Oscillating Model

• Big Bang Theory

The steady state theory suggested that the universe has always existed and maintains the same structure. This theory was later discredited due to which discovery?

• The amount of hydrogen in the universe is extremely high to remain steady.

• The scale of the universe is much greater than was previously understood.

• The shift of light toward longer wavelengths indicates that most galaxies are moving away from Earth.

• More powerful telescopes have made observations of planets orbiting stars other than the Sun.
