So… what if we’ve been living inside a black hole this whole time?

Anyone here into space, the universe, or alien theories? Just to spark your curiosity today some physicists have proposed that our entire universe might actually exist inside a black hole.
It’s both mind-blowing and humbling. Makes you wonder… maybe we're just part of a cosmic cycle.
Who knows? Maybe black holes don’t end things maybe they begin them.

It sounds like sci-fi, but it’s based on real theories in general relativity. The idea is that a black hole in a higher-dimensional space (a "parent universe") could contain a whole new universe within it,, ours.

It would explain a lot:

• Why time behaves strangely near black holes (and maybe why we experience time the way we do)
• Why the universe is expanding similar to how space-time stretches inside a black hole
• And why we might never detect what's "outside" our universe because the event horizon seals us in

Let me know your thoughts, I love diving into these rabbit holes (or... black holes 😅)
