Dark Matter and Dark Energy cannot be detected though they are presumable all around us.
The effects of these things have been detected though, and work to understand them is ongoing - science is like that, and it takes time and structured effort to progress from early observations to a fuller understanding, and even then knowledge is provisional. For example, back in antiquity people would have recognised the medical condition we call diabetes without them knowing anything about insulin (or hormones in general) but, over time, medical science did progress so that we now understand that condition well enough to have developed treatments.
11 dimensions cannot be detected or even imagined, even though they are supposedly a part of our real universe. And yet all these are accepted as possibilities merely because of some mathematics on pieces of paper.
And here is something that explains the working of the mind and is something that many people can actually feel around them and work with everyday...and its all hocus pocus....!!!
Its a mindset problem, guys! Its all in the programming.
You're conflating scientific theories, based on the likes of mathematics or other related theories, that in due course will be investigated once methods are developed, and quite possibly be rejected, with unsubstantiated woo that you say already exists for which there is, as yet, no reasonable basis to accept.
