a. Describe the big bang theory. (1 point) b. Match each model of the universe with the future it predicts. (1 point) A. Closed B. Flat C. Open The universe will stop expanding but will not collapse. The universe will continue to expand forever. The universe will stop expanding and then collapse back to its point of origin. c. Match each observation to the conclusion it supports in the big bang theory. (1 point) A. Light from other galaxies is shifted toward the red end of the spectrum. B. Cosmic background radiation appears uniform across the sky. C. The amount of helium in the universe matches predictions. Nucleosynthesis of light elements occurred shortly after the expansion of the original ball of energy. The universe is expanding. The universe began from a single point.

A)

The Big Bang is the earliest known event in the observable Universe, its earliest known phase of evolution, and the name of the model for this process. According to this scenario, the Big Bang took place around 13.800 million years ago, when the known Universe emerged from very dense and hot matter. This theory is based on observations showing that space is expanding from an initial state where all the matter in the universe had a very high density and temperature, to a more cold and stable one.

B)

A. Closed. The universe will stop expanding and then collapse back to its point of origin.

B. Flat. The universe will stop expanding but will not collapse.

C. Open. The universe will continue to expand forever.
