Although it is true that the observable universe is 900 million light-centuries wide and that light travels at 671 million miles per hour, it is still a small fraction of the estimated 10500 universes. Therefore, it is possible that the observable universe is either nearly or exactly 0% of the actual universe. This means that the actual universe could be infinitely large, so urrong, space may not necessarily have boundaries. However, it is still unclear whether space is finite or infinite because there is no concrete evidence to support either side. The public may not be as interested in this topic as you are, but that doesn’t mean that the research to gain an answer has stopped. It is still possible to uncover the answer, it just takes some time.
