Dark matter has a gravitational lensing effect on light. For more explanation see:

The most likely particle associated with dark matter is the WIMP. Researchers are continuing to come up with results leading to a clearer explanation for the difficult to detect particle.
Dark matter found at last? WIMPS in space might hold the crucial clue | Mail Online
Are you referring to some imagined, supposedly conscious, supernatural, human-like, "perfect" being?
Are you referring to our reality, our universe, being created from membranes by an ekpyrotic explosive expansion that is described with M-Theory?
Gravitational lensing... Doesn't explain why these particles themselves do not interact with light. I understand that gravity is the strongest explanation for why
what we assume is a lensing effect is occurring.
Why haven't WIMP's been found in a laboratory? Our particle accelerators have never produced anything with properties even remotely similar to a WIMP. Why is it that in the first 15 years of searching for WIMP's using methods exactly as described or similar to the one in the article you linked me to (Watch through the wormhole, they have a whole episode devoted to dark matter; the amount of "luck" in finding these things is atrocious) found nothing. If these particles are so massive, then why doesn't the atmosphere show signs of being knocked around by massive particle collisions.
The whole point is that all we have is an
Observation. We don't have something being predicted that has a testable consequence. If you posit an invisible dragon that makes no noise, has no smell, and can pass through solid objects, then how is this any different than dark matter which has no known interactions, doesn't affect light except through gravity (which may not even be the case since other mechanisms can produce a lensing effect or simulate one), and apparently passes through objects all the time without leaving any trace.
And are you serious? Your bias against philosophy astounds me (this isn't even about religion anymore). Explain to me how you got imagined, conscious, supernatural, human-like being out of: "This "thing" if it can be called a thing has no attributable qualities; it is outside of existence entirely and to assert any qualities what-so-ever is false to the point of absurdity?"
No, I am not talking about our universe possibly being the result of a membrane. That is almost trivial in comparison to what I am actually asking you to consider. Assume for a moment that M theory is correct. Well, why are their strings at all? Why are there membranes? So you posit some explanation for membranes. This explanation needs some causal basis; something has to support this.
You do this however many times it takes to either find a breaking point BAM! This is the end OR find out that it can be shown that reality has no appreciable end point. Reality (this is universe + whatever might happen to be outside the universe) might be eternal and uncreated; it might be possible to back track in "time" as far back as you want to try. It might ALSO be possible that you can't; that reality has a firm beginning point.
What I am saying is I am asking you to consider what happens if the framework of existence; that system upon which all other systems are based; the quality or faculty which allows for bare existence to be true ITSELF HAD A BEGINNING?
This is the game two year olds play when they first learn the word "Why." They keep asking until a breaking point happens; either the other person gives up or they have no appreciable way to understand they answer and they give up. In this case, whether or not the universe has a beginning is only relevant IF AND ONLY IF you suppose that there is nothing outside the universe (No parallel universes, no membranes, no anything). But then, if you assume that the universe is in fact all there is, then you have to ask yourself: What happens if the universe actually had a beginning?
How do you get something from nothing? The answer is that given logic and existence you can't. As long as identity is in play (A=A is tautologically true), then you can't have creation ex nihilo. So then what if the universe (where we assume it is all there is) had a beginning? Well you need something which avoids logic entirely.
The only facet of logic which can derive anything (including the system within which it resides) is a contradiction. The principle of explosion allows you to get anything from a contradiction. The only way to assert a contradiction in a "valid" manner is if the entire universe of discourse were indeterminate.
What I am telling you is that if there is a First Cause; a Prime Mover; An Uncaused Causer; Consummate Perfection; Transcendent Absolute; etc then it has, First and Foremost, the property of being Completely and Utterly indiscriminate and nothing can be attributed to it in a manner which is true, and thus it is beyond the comprehension of beings which exist (flatly). It cannot be comprehended by us in anyway. The only thing to know about this "being" (it technically isn't a being) is that it is wholly unknowable.
There isn't any special relationship; no prayers; no mythos; no mind; no decisions; no awareness; NOTHING. This "thing" might technically be the only thing which can be called supernatural and still have the term mean a bloody thing.
Side Note: I don't believe there is actually any such thing as "supernatural." Either something is real and it has real effects; in which case it is natural, or it doesn't have any effects which aren't imagined; in which case it is imaginary and therefore not real. So if it turns out that turnips + wing of bat + tongue of salamander = live for 3000 years, then this still isn't supernatural; it's just a previously unexplored aspect of the natural world.
