Sorry, I think I meant any virtual particle that can become Hawking radiation.

According to Black Hole Complementarity, when an observer sees another falling into a black hole, the effect that gravity has on light waves would make any observation of the person slow down, eventually stopping him before he hits the horizon. In addition, he will appear to be "stretched" across the whole horizon, his particles being hit and separated by the halves of virtual photon pairs that, since the other half is unobservable inside the horizon, have the same effect as normal photons. Meanwhile, to the one falling in, there is nothing particularly interesting about the horizon. Am I correct? Then in theory, say the person falling in is feet first. What will happen? Will his feet appear to slow down and never hit the horizon although he should observe nothing special at the horizon? In addition, since the stretched horizon (hot membrane resulting from aforementioned unruh effect) is above the horizon, won't the person falling in observe it anyways?

Hi, I'm laifuthegreat and I'm nowhere near as intelligent as the majority of the forums.

Note* I'm not a professional, I'm a high school student with an interest in physics. There seems to have been some debate within the world of modern physics about recent discoveries making it even more unlikely that the universe would be built to support life. They amount of dark matter and energy is balanced perfectly to allow for the universe to support life. There's been many proposed solutions, including there being multiple universes, therefore allowing it to just be a product of probability. However, I'm personally confused about the problem. If there is absolutely no significance to life, no God, no purpose, then why does it matter? While the universe may be finely tuned for life, this should hold no more significance than a particular speck of dust being where it is? It's improbable, but all outcomes are one of many possibilities, one of them still has to occur. Since life holds no significance, the fact that the universe has life against all odds is also insignificant. I am sure that there is a problem with this logic, so can someone explain it to me?
