The universe consists of definitive boundaries that delineate physical reality from what can be imagined. Within this framework, there are elements that may exist beyond our capacity to conceive. The idea of supermassive black holes potentially leading to other universes reflects the intriguing theories surrounding the multiverse, highlighting the intersection of philosophy and physics. However, any claims about unobservable phenomena remain speculative without direct evidence. Emphasizing the importance of mathematical foundations, one advocates for focusing on theories grounded in observable reality rather than those based purely on abstract imagination.
