How did the discovery of Cosmic Microwave Background Radiation support the Big Bang Theory?

• It suggests that Hydrogen and Helium were the first elements to form.

• Expanding

The universe is believed to be approximately 14 billion years old. As a result of gravitational attraction, which MOST likely developed first after the big bang?

• a planet

• a moon

• a galxay

• a star

Radio astronomers Arno Penzias and Robert Wilson discovered a microwave signal during their research in 1964. The microwaves were uniform and coming from all directions in the sky. The phenomenon known as Cosmic Microwave Background (CMB) provided evidence that the universe was once very hot and dense.

• CMB confirmed how matter expanded during the big bang.

• CMB was the magnetic field that was created during the big bang.

• CMB was a reflection of the thermal energy generated during the big bang.

• CMB represented energy trails from moving matter that began with the big bang.

What scientific observation did Edwin Hubble use to determine distances between galaxies?

• As the light source passes Earth, the wavelength increases as the frequency increases.

• As the light source moves toward Earth, the wavelength decreases as the frequency increases

• As the light source moves away from Earth, the wavelength increases as the frequency decreases.

• As the light source affects the gravity of Earth, the wavelength decreases as the frequency decreases.
