How do we know that the universe is actually expanding? What if everything inside the universe is just shrinking?

but yeah the universe is expanding and the earth is definitely doing at least 4 different movements right now :^)
What if the light pellets are shrinking too?
Gravity keeps distances relative.
>gravity that can't even stop a helium balloon from soaring or butterflies from flying
Some nature things can ignore gravity... birds can because they evolved to... but stars can't, that's why they orbit the megastar at the center of our galaxy, and that megastar is influenced by other galaxies' megastar centers.
Pellets?!

You know, the light pellets the sun emits that lets us see everything, they bounce around and into our eyes. They look red because it's the illusion that they are running away from us when they're actually shrinking.
>birds can ignore gravity
>biological creatures can ignore physics
They don't bounce around. This is not how photons actually work. This is the high school definition of photons to make them seem less odd than they are.
Yeah, because of their wings, retard.

Not an argument.
There are times when it's not worth an argument. Your statement is so fucking retarded that I would gain absolutely nothing from arguing with you.
