Which statements are true and support the Big Bang Theory

Red shift of light from galaxies as they move further apart?
Cosmic Microwave Background Radiations uniform temperature?
Blue shift of light from luminous objects moving towar observer?
Cooling of the universe as it expands from a dense singularity
Dark matter makes up the majority of matter in the galaxy

The statements that are true and support the Big Bang Theory are:

1. Red shift of light from galaxies as they move further apart: This is known as the Doppler effect, and it provides evidence that galaxies are moving away from us. This observation is consistent with the expansion of the universe as predicted by the Big Bang Theory.

2. Cosmic Microwave Background Radiations uniform temperature: The Cosmic Microwave Background (CMB) radiation is a faint energy leftover from the early stages of the universe. The fact that it has a uniform temperature in all directions supports the idea that the universe was once in a hot and dense state, as predicted by the Big Bang Theory.

3. Cooling of the universe as it expands from a dense singularity: The expansion of the universe leads to a decrease in temperature, which is consistent with the Big Bang Theory. As the universe expands, it becomes less dense and therefore cools down.

On the other hand, the statements that are not true or do not necessarily support the Big Bang Theory are:

1. Blue shift of light from luminous objects moving towards the observer: A blue shift occurs when an object is moving towards an observer and the wavelength of its light is compressed, resulting in a higher frequency and a shift towards the blue end of the spectrum. While blue shifts can occur in various scenarios, they are not specifically linked to the Big Bang Theory.

2. Dark matter makes up the majority of matter in the galaxy: The concept of dark matter is not directly related to the Big Bang Theory. Dark matter refers to hypothetical matter that does not interact with light or other forms of electromagnetic radiation, but its presence is inferred through its gravitational effects on visible matter. While it may play a role in the dynamics and evolution of the universe, its composition and abundance are still not completely understood.
