The "origin of its own domain" simply means that the origin of the universe cannot be explained using the scientific method. Science is the study of physical reality, and if there was a point at which physical reality (the universe) didn't exist, then there can be no scientific method used to explain its origins.
If, that's the main point...if. Science doesn't seem to be claiming that the Universe from nothing, it seems to be applying that the Universe as we know it now, is not like the Universe as it was back at the time of the big bang.
I'm not at anyways of an expert so what I'm saying may indeed be incorrect. We know that at a point of a black hole gravity becomes so strong that all matter is put into a point where it is infinitely dense with infinite mass (correct me if I'm wrong), this point is called a singularity. All that swirling condensed mass creates energy however as it's gathered towards that point that is released. This released energy output is massive, in the theorized black holes in the middle of every galaxy this output comes out to 1000X's the output of our milkyway. That's a lot of mass producing that energy. If the big bang was anything like that but on a larger scale, it would make sense that hte mass and energy expelled from that energy output would result in our current universe. Now if your question is where did that mass and energy come from, well that I don't know, but just as you can say God always was, you can make the same claim that Matter and Energy always were.
Morality, the sense of right and wrong. Evolution or natural selection doesn't tell us whether Nazi Germany's worldview was right or wrong. Evolution or natural selection doesn't tell us whether rape or murder is wrong. In order to have objective morality, there must be a moral standard that transcends the standard of mankind
.
What is objective morality? There really doesn't seem to be any, morality may be objective by civilizations, by societies, but certainly not overwhelmingly as a species. Again I point to slavery, is it moral to own another human being. Not how you treat them, not whether it was the only situation that could work for them (because in that case the moral option would be to create a society where such a case does not exist). The OT seems to indicate that slavery is not immoral. The United States for the first 200+ years of it's existence certainly looked it as moral. As did many nations, now we look at it as a detestable act. Is it rape if a husband has sex with his wife despite her not wanting to? If so, is that moral? Does a woman even have the moral right to deny her husband sexual satisfaction? Despite the belief that women should submit to their husbands. Because that is considered a form of rape, but few hundred years ago, that wasn't an issue. If morality is objective and our immoral behavior results in destruction, then our history of slavery, rape, murder among the human species should have ended up with our demise millennia ago.
We have the pieces, but we can't seem to find out how these pieces "came together" without Intelligent Design. So if this is what you (in general) believe, you have to believe that a blind, mindless process was able to do something yesterday that intelligent people of today haven't yet figured out how to do.
Blind and Mindless are related to things that are alive. When it gets cold doesn't water freeze? When it gets too hot water evaporates. That is a blind and mindless process but it does it anyway. Is it intelligent design telling water that it needs to do this? I do believe that the laws were put into place, but in what means IDK, for all we know God can be a being from another Universe that visited ours and likes ours so much that adopted us because God was lonely. Who really knows? But claiming intelligent design doesn't prove the existence of the Christian God, just a God, or An Intelligent Designer.
If you start the universe off with a big bang, at no point will you get consioussness. If you are sad, are you sad, or is your brain sad? If you are happy; are you happy, or is your brain happy? At best we can show that the brain and the mind correlate, but they are not the same thing. The brain and mind are independent of each other and if the brain cant be used to explain the origin of the mind, yet the mind exist, then where does it get its origins?
This interesting because it seems people ignore how our nervous and endocrine system works. IT also ignores the connection between our brains and our bodies. When you touch a hot stove, you jerk your hand away, your brain isn't the one that told you to do that, that was an automatic response ignoring your brain, because it doesn't need the time to decide whether or not touching this is a good idea. The pain however reinforces for your brain that this is unpleasant, at that point your body floods with endorphins to ease the pain. We now make the connection that something that burns us leads to pain, and so we avoid hot things. Our bodies produce lots of chemicals some react slowly some react quickly. Let someone scare you and see how quickly you want to run away. Animals have that same instinct too, It is an early form of reasoning. If I do X, Y will happen, I do not like Y because Y makes me feel bad. Same as how animals will look for drugs and alcohol (elephants, Jaguars, monkeys), because there is a form of reasoning (I will consume X because X causes Y and Y felt good, so the more Y i have the more I will feel Good), What is Good? The release of Dopamine, something that is found in some bacteria and almost all multicellular organisms and so far only in arthropods has the "reward/action repeat" effects of dopamine not been shown...they have some other form that does this...however what is the mind? How do you define it?
So answer me this, how can you explain the origins of the universe by using science??
We can do a lot of cool things with science, no doubt. But we are speaking in terms of absolute origins. Those are the deeper questions.
I don't know, I"m not a scientist, what I do know is that at one point people thought that touching the heavens would be impossible, but we have landed on the moon. We've seen distant galaxies, every week we push the presupposed limits on us. So I cannot agree that Science will never know, because we haven't seen the end of science.
