Black holes could potentially serve as tunnels between parallel universes. Famed physicist Stephen Hawking once proposed that every black hole may give birth to a new universe. Whatever matter a black hole consumes, could reappear in a universe on the other side of the black hole. This suggests that black holes might not just be gravitational phenomena, but could also serve as conduits to other universes.
Currently, scientists cannot directly observe what lies inside a black hole, nor is there any evidence to prove that black holes serve as tunnels connecting universes. There is also no proof of the existence of wormholes or parallel universes in the cosmos. These theories remain under intense scrutiny and exploration in the scientific community, with black holes, parallel universes, and wormholes being significant topics of inquiry due to their complexity and mysterious nature.
What has been definitively proven by scientific research to date is that black holes do indeed exist. They possess an immense gravitational pull that exceeds all expectations. Any object that comes within a black hole’s reach is inevitably drawn in, including light, which cannot escape. Objects are pulled towards the center in what is known as free fall.
From the perspective of general relativity, the passage of time inside a black hole is drastically different from that outside. As one approaches the center, time slows down significantly, and may even appear to stop. This means that any matter or person entering a black hole would gradually vanish, becoming completely disconnected from the external world we know. Thus, black holes are profoundly enigmatic, and our current understanding of them is based on limited information.
