As far as I know the deepest spot on earth is the Marianas Trench. 7 miles deep I think. Would you like to go down that far to see it?

Or would you rather go in the opposite direction out to vast universes and see what's there?

Of course there is a third option. For the incurious. Stay right here and focus on this and question nothing beyond what you can see touch feel hear taste. Different strokes.
