Reflecting about that i.e. just 6 parameters whose value have to be like they are with a high degree of precision to have a universe like ours and that the probability for having those 6 values to be as they are should have a very low probability in connection with the theories about multiverse. They write that it may be that an infinite number of universes pop up and disappear, exist at the same "time", the concept of time and simultaneity are equally to be used in awareness of the concept in a context of science and physics and cosmology. It just is said it happens to be that only in this universe or those with equal values of i.e. those 6 numbers there is the possibility to have life and intelligence develop so that there are individuals who can reflect about this kind of questions. I did apply in my reflections this fact that a universe like ours is extremely unlikely to be but that still the event of such an universe is actually in place and the one in which we live. Why i.e can we not ask ourselves the question about how a such universe that is in extreme not probable would have to be without conflict of what we know about our universe and its laws of physics would have to be to make possible beaming yourself from any place in the universe to any other place in an economic and efficient way and that we could detect the property in an affordable and possible way within the reach of our technology and our science? I know, such an universe is totally not probable and its probability to be true is in extreme low. But is not our universe with its parameters of which the 6 numbers in the book of Martin Rees refer to also highly unlikely? So I am postulating that being in an universe whose defining properties require i.e. those 6 parameters to be as they are to a high degree of precision is not equally unlikely and why can we not happen to be in a universe where properties not being in conflict with what we know about the universe and that can be detected with our knowledge and science? If you apply additionally to this the concepts of those "parallel universes" next to each other like layers as some studies related to the string theories, the just by searching for such properties specified we might result of being in a "layer" that has this additional properties? As I wrote at the beginning, this are just reflections. But if I would be 4 decades younger than I am and would love physics as I have always done this would be a direction I would love to study and research! Just to put in relation as to how little we really know about how even just our universe is. Just a few years ago we had not even a clue about what euphemistically we call dark energy and dark matter. And this makes up the dominant part of what exists in our universe!
