Physicists have proposed that our universe exists inside of a Black Hole of a higher dimensional Universe.
Have you ever wondered what lies beyond the observable universe? What if our universe is just a tiny part of a much larger and more complex reality? What if our universe exists inside of a Black Hole?

This may sound like a science fiction scenario, but some physicists have proposed that this could be the case. In this article, we will explore the idea that universe exists inside of a Black Hole, and what implications this would have for our understanding of cosmology and physics.

What is a black hole?
A black hole is a region of space where gravity is so strong that nothing can escape, not even light. According to Einstein’s theory of general relativity, black holes are formed when massive stars collapse at the end of their life cycle. The resulting singularity is a point of infinite density and zero volume, where the laws of physics break down.
The boundary of a black hole is called the event horizon, which marks the point of no return for anything that crosses it. The size of the event horizon depends on the mass of the black hole. For example, a black hole with the mass of the sun would have an event horizon of about 3 kilometers in radius.
How Could Our Universe exists inside of a Black Hole?
One way to approach this question is to ask: what happens inside a black hole? According to classical physics, nothing can survive inside a black hole. However, quantum physics suggests that there may be some form of structure or information that persists beyond the event horizon.
One possibility is that the singularity at the center of a black hole is not a point, but a sphere or a torus. This would create a wormhole, a shortcut in space-time that connects two distant regions of the universe. In this case, one end of the wormhole would be inside the black hole, and the other end would be outside in another region of space.
Another possibility is that the singularity at the center of a black hole is not a sphere or a torus, but a hyper-sphere or a hyper-torus. This would create a bubble universe, a self-contained region of space-time that has its own laws of physics and constants. In this case, the bubble universe exists inside of a Black Hole, and our observable universe would be just a part of it.
What evidence do we have for this hypothesis?
The idea that our universe exists inside of a Black Hole is speculative and has not been proven by any direct observation or experiment. However, there are some indirect clues that support this hypothesis.
One clue is the cosmic microwave background (CMB), which is the radiation left over from the Big Bang. The CMB has a uniform temperature across the sky, except for tiny fluctuations that reveal the structure of the early universe. Some physicists have argued that these fluctuations could be explained by assuming that our universe exists inside of a Black Hole, and that the CMB is actually the radiation emitted by the event horizon.
Another clue is the expansion of the universe. According to the standard model of cosmology, our universe is expanding at an accelerating rate due to dark energy, a mysterious force that counteracts gravity. However, some physicists have proposed that dark energy could be an illusion caused by assuming that our universe is flat and infinite. If our universe is actually curved and finite, as it would be inside of a black hole, then dark energy would not be needed to explain the expansion.
What implications would this have for our understanding of cosmology and physics?
If our universe exists inside of a Black Hole, then this would have profound implications for our understanding of cosmology and physics. For one thing, it would mean that our universe has an origin and an end, and that it may not be unique or isolated. It would also mean that there may be other universes beyond ours, either connected by wormholes or existing as separate bubbles.
Moreover, it would mean that there may be new laws of physics and new dimensions of reality that we have not yet discovered or understood. It would also mean that there may be paradoxes and contradictions between quantum mechanics and general relativity that need to be resolved.
In short, it would mean that our universe is much more mysterious and fascinating than we ever imagined.
