Fine tuning specifics (Introduction)

We have no idea why our universe has the finely tuned paraters it has or why they have to be the way they are. All we have done is measure and fit them together. There is no underlying theory. Even if there are multiverses thaat explains nothing. And the Anthropic Priciple is a bogus mess of circular reasoning. It is an example of why scientists need philosophers of science to explain it rationally.:-https://medium.com/starts-with-a-bang/1a2a340bf94a-"Why does our Universe have particles and interactions with the properties that we observe them to have, instead of any other possibilities?-"These are legitimate scientific questions, and there are many people working on uncovering legitimate theoretical answers to them. The general school of thought that these questions may have answers that are knowable to someone in this Universe is known as dynamics, or the notion that there is a physical answer to this question. The alternative is that "the Universe just kind of is this way and there is no knowable reason."-"So, as scientists, we are left with two options:
1.Work as hard as we can to find the dynamics that lead our Universe to be the way it is.
2.Give up on dynamics, and make arguments to justify our ignorance.-"And there are many scientists — surprisingly and frustratingly — who have chosen the second path.-"Simply speaking, the anthropic principle is the idea that the Universe is the way it is to us because it needed to be this way, or there would be no observers here to observe it. The fact that we are here, observing it right now, tells us that the Universe couldn't have existed in a way inconsistent with the potential existence of intelligent observers.-"This is true, of course, but that's all we can learn from it. The question we want to answer is how: how did the Universe come to be this way, to have these properties? And saying "the anthropic principle" or (even worse) "the multiverse" simply isn't going to cut it.-"A statement or admission of our own ignorance, that we do not understand the dynamics that gave rise to the constants of our Universe, does not mean that there are none, that all values are taken on somewhere in some Universe, and that ours just happens to have the values it does, which are serendipitous to our existence.-"That line of thinking not only isn't even science, it's a cop-out, and a distraction from those who are actually seeking scientific answers to the hardest of scientific problems out there.-"The multiverse may be real, but it doesn't hold the answer to the question of why the fundamental constants have the values they do. It can constrain what they must be, but that's all the anthropic principle can do. To get the rest of the way there — to understand why our Universe has the properties it does — requires that we look for dynamics. They may not exist in an accessible way in our Universe, but we have to try, we have to look, and we have to ask.-"The cost of giving up, of not looking for an answer that the Universe might actually reveal if we did, is far too high."
