That reminds me someone told me I lost wait and I knew it was a dream. I was right.

You just need to be more patient.

I have space questions:

1) Do we view space as an area interior space similar to navigating the ocean or an exterior space like navigating the planet (where you can walk in the same direction and end up where you started).

2) if we view it like the ocean how do we know that the north pole is actually in the z positive direction from the earths core?

You would never return to where you started.

Up is defined as away from the center of the earth defined by gravity and north is determined using the positioning of electrons / magnet / the compass

You mean “z” as in 3D contrasted X and Y coordinates, right?

Yes. If the universe is a giant box and the earths core is at the origin how do we know the north pole is is the z positive direction of the coordinate system? Do we actually know or is it just depicted that way?

It’s depicted that way because we think of the North Pole relative to the earth’s core since we live on earth

If an alien in the sombrero galaxy drew the grid it would be a hell of a coincidence if it lined up like that but only a coincidence

Yeah, I get that. I want to know if we know our actual orientation in the universe.

It is just depicted that way. What you're touching upon here is one of the fundamentals of special relativity: there exists no absolute coordinate system, only coordinates relative to other things, so we might as well conveniently define the z axis by the earth's north pole

Edit: and as far as I remember the space of our universe is probably slightly positively curved, which might mean that you would end up where you started if you travelled in a straight line. I'm not certain though

hrmm... i need to find a space nerd to have this convo in person with.
