Is the event horizon of a black hole physical?

In summary: Bekenstein-Hawking entropy of a black hole. This was a bit like a physicist admitting that a year's salary was exactly equal to the price of a new car. It was a fact that nobody could deny...In summary, the conversation discusses the issue of whether or not the event horizon of a black hole is physical. Some argue that it is physical, while others argue that it is merely a set of coordinates. The concept of physicality is debated, with some defining it as something that can be touched or interacted with, while others include energy and matter in their definition. The idea of a "firewall" at the event horizon is also mentioned, and potential explanations for the horizon's physicality are discussed,
