![]() In the end, "information" is a great way of boiling things down to a simple concept. And yes, you can approach the event horizon closely and find out things about it - as long as you stay on the same side. But every single time, you need to think of some explanation, justifying your answer. Some of them might make sense physically, some might be completely hare brained. You can think of all sorts of crazy schemes. How about things, that just get really close, but don't cross into it? What about things on the very surface of the event horizon? What about tiny, tiny, minuscle things? What about, if I deform the black hole a little bit? But once you make this off-hand remark, people think of loop holes. In layman's terms, you want to express the concept of "nothing can leave a black hole". We don't even have any experimental evidence that Hawking radiation exists yet.Īnyway, it's not an answer you are going to get with experimental certainty in your lifetime, though there are a lot of mathematical models on the question. But that still wouldn't really tell us what happened inside of one. So when I say science may never know, that's not quite true because it technically would be possible to recreate things that went into the black hole by capturing and measuring hawking radiation of one. Now, recently it has been shown (mathematically modeled) that Hawking radiation preserves the information of the stuff that was inside the black hole. The nice thing about science is that it's ok to not know the answer to something. To be certain, we would need experimental data and observations from inside a black hole, which by definition is impossible to receive information from. What happens inside of a black hole is one thing science will probably never be able to answer with certainty. What do we need to reach answers to these questions? We make our world significant by the courage of our questions and by the depth of our answers.
