Are you sure? As far as I know, none of those have testable explanations.

> Consciousness

Neurology has a lot of information about where consciousness comes from. It's not complete, but nothing we know is.

> experience, spontaneity

More neurology, from what I can tell that these words mean. However, they're vague, and can be defined in so many ways that I don't know precisely what you mean.

> 'the present moment'

This is amazingly vague. It could be related to time, to consciousness, or to who-knows-what.

That begs the question: if you weren't sure what was meant by the terms, why did you assert that they were "all part of science"?

As I understand them they are. I don't know what you mean by them.
