Eli5: If there’s infinite stars, why isn’t our night sky completely lit up?

2.09K views

As the title says, if there’s infinite stars, wouldn’t the light from all of them have reached us and made our night sky become completely white from the number of stars there are? Is there just not enough stars in proximity to earth for all the light to reach us in time to see?

I’m sure there’s a simple answer, but it’s 1am here and my brain can’t figure it out.

The Universe hasn’t been around forever, and therefore we can only observe stars and galaxies that are a specific and finite distance away. Therefore, we can only receive a finite amount of light, heat, and energy from them, and there cannot be an arbitrarily large amount of light in our night sky.
