You'll be amazed to learn that if you fell into a supermassive black hole, you wouldn't even feel yourself cross the event horizon – it would just feel like you're floating in free fall! But hold on, if it's a smaller black hole, things get wild: you'd experience immense 'tidal forces' that would stretch and squash you, famously known as 'spaghettification,' long before you hit the center. Imagine someone watching you from afar: they'd see your time tick slower and slower as you approach the black hole, eventually appearing to completely stop at the event horizon – meaning they'd never actually see you fall in. This creates a mind-bending paradox: from your perspective, you're definitely going into the black hole, but from an outside observer's view, you never cross the threshold! You'll hear about a mind-blowing paradox: from an outside perspective, you'd be 'incinerated' by intense radiation before even crossing the event horizon, and your information would escape! But from your own point of view, Einstein's theory says you'd definitely fall in and face 'spaghettification' as you approach the singularity – a totally different, gruesome end! Get ready for the concept of 'black hole complementarity,' a modern idea suggesting that both these drastically different fates are true, depending on whose perspective you're taking – it really pushes your understanding of reality. This leads to a deep quantum mechanics puzzle: if your information comes out, but you also go in, are you duplicated? The 'no cloning theorem' says that's impossible, hinting at wild solutions like wormholes connecting the inside and outside of the black hole! we wouldn't even notice something according to Einstein's theory as we fall across the horizon into the interior of the black hole So from the point of view of someone outside, nothing goes into the black hole ever. According to Einstein's theory, what would a person experience as they cross the event horizon of a supermassive black hole? From the perspective of an observer outside a black hole, what happens to an object as it approaches the event horizon? What is the primary difference in the experience of spaghettification between falling into a smaller black hole versus a supermassive one? What does the principle of Black Hole Complementarity suggest about the fate of an object falling into a black hole? Why is the 'no cloning theorem' a significant problem when considering the information paradox of black holes?
