Maybe that's because using observational evidence isn't "delving more and more into the mystical."
Infinite universes and many other modern theories are so out of the understanding of man and so beyond the realm of human understanding, that it is as good as mystical.
The scientists can’t understand it, or explain it. The state of the “cosmic egg” pre big bang is not within the realm of human understanding. Nor is where it came from. Nor is the concept of infinite universes beyond our cosmic egg/ big bang universe (which was supposed to contain everything), nor is a cat that is both dead AND alive but not until you observe it (quantum theory), nor is the timeless ingularity of a black hole, or the other dimensions it may lead to. All these take the scientists into realms they cannot understand, observe, or see beyond. In that sense, the limits of science mesh quite well with the mysticism of religion.
You don’t think it’s as mystical as God? What is God, except the infinite, that which preceded everything, he is indeterminate and mysterious, he is beyond time and space, all knowing, all powerful.
How are the modern mysteries of science any different than the spiritualist’s yearning for God?
You realize of course the scientists have not observed any other universes, and certainly not infinite universes? Almost by definition, they cannot see anything beyond this universe.
What they have done is, using Earth bound observations, decided there are a few areas of the sky in which they see variations in the cosmic background radiation.
Now, a non-religious person might say that’s interesting, maybe our ability to detect the radiation is inaccurate, etc.
But the “religious mystical scientist” makes a splash by theorizing that we are observing the “bruising” of our universe from 4 of the “infinite universes” which they theorize exist and actually “bump into” our universe.
I hope you don’t think this is anything other than an enormous and unknowable, unprovable leap of faith by the scientists? Because they sure as hell did not observe any of the things they are theorizing based on scant data.
I’m not commenting as a religious, or as a scientist, and neither are they.
