Space-Ocean

So we live on this planet Earth, we know all that we know. What about all the creations that are outside of our ability to grasp? The Heilige Bashefer created so many wonders, space, planets, galaxies, the deep ocean which apparently we know less than what we know about space. What about all these wonderful Niflaos that noone knows about? Hashem created these things, are we not meant to know of them? When a person creates or makes something they feel a need and want to share it with others. I know we done speak for Hashem, but what is the meaning of not being able to know any of these wonders? Also does space and the ocean have to do with Olam Haba? Is it like a separate world? After all there are Malachim in the universe and apparently there are so many galaxies that Hashem created. It is truly a wonder….
