Why is space black?

The video explores why space appears black, starting with Olbers Paradox, which questions why the night sky isn't as bright as a star if the universe is infinite. It explains that the universe is finite and expanding, supported by the Hubble constant and redshift observations. Human vision limitations also contribute to the perception of a black night sky, as our eyes can't detect the dim colors present. The video concludes by linking these concepts to broader questions about the universe's nature.

What evidence suggests that the universe has a beginning and is not everlasting?

How do human eyes perceive colors at night compared to during the day?

What role does Rayleigh scattering play in the color of the night sky?
