I don't think there is an up in the universe.

On Earth, there is clearly an up and down.

Feet on the ground: down

Opposite direction of feet: up

But my ups are different from the ups of people on the other side of the planet. Our ups are literally at opposite directions.

And in space? There is literally no up or down because there is no/ not enough gravity to make an up or down for you.

You in space looking at the Earth while it's upside-down to you? Welp, nothing you can do about it.

And do you know what that means?

You could look at the Milky Way galaxy "upside-down" and that would technically be the right direction. You could look at the Milky Way galaxy "sideways" and it would technically be the right direction. You spin and flip in all directions and diagonally; no matter where you face, it would technically be the right direction.....
