#impossiblespace

What makes a space impossible? How do we know whether or not a space can really exist within the confines of the space itself if we have no real way or understanding of how to get there, or how to leave there. Is the space we live in impossible? Is the force dragging us down to the center of the earth pretty much something impossible? You can say "Is that real?" or "Does that really exist?" about any space. Is the concept of space impossible. Rooms are never endless but could that be logical. Could separations like doors and walls, and things to contain us like tall buildings be more impossible then walking on air. Could the confines of space be impossible. Impossible to contain air, water, life?
