It really depends on what you mean? It’s a purposely, nearly obtusely, intangible concept. I’m not unwilling to talk about it if I get a proper definition, but my opinion would be a mere opinion formed from the facts I have on hand. I have some suppositions that are outside the realm of what science has been able to dig in to, but without actually factual backing, I also acknowledge that my ideas are conjecture that line up with how I perceive the world.
