Following is about Space around our globe. Same kind of comment can be applied to all Cosmic Matter. How though?
The Outer Space Treaty represented a recognition that no one can own space because once you reach orbit, you circle the globe every 90 minutes, so international boundaries disappear. That’s why it should be a place of cooperation rather than conflict. Unfortunately, space is also a place of high strategic value from a military point of view, which is why talk of space as a “war-fighting domain” is disturbing and violates the spirit of the agreement signed more than 50 years ago.
May common sense, and the spirit of that treaty prevail. (Extract from comment by Bob McDonald of CBC).
