Just don't call what you're doing science.
For some, it is enough to observe the physical world from the visual, corporeal, four dimensional level. But for us, that does not satisfy.
We wonder why it is a certain way and not another, why it exists at all, what it is really made of, of what it is a part, where it came from, where it will lead.
To answer such questions concerning life (in particular here, biological life) - complexity [the issue on that thread, here it is the will to live] must be broached. Of course there are many mathematical tools to accomplish this - and different investigators are drawn to different toolboxes...
But such things are not of particular interest to everyone. So if you're not curious, then "no problemo"...
As evidence, here is an article comparing cosmologies. Please notice that all quantum cosmologies have a foot in the physically observable but otherwise are altogether speculative. The same could be said of string theory and a few decades ago, black hole theory.
Our investigation here has more than a single foothold, btw.
I could be, but I don't think so.
Cosmology at least has some relation to the observable universe. 'Life fields' are the domain of spiritualists.
