--or....Or....OR....maybe someone made a miscalculation in one of the fundamental laws, and scientists are manufacturing things to fill these giant dark holes with made-up objects which can neither be observed nor discredited.

Haha...you're very cynical Daniel, but yeah, as time goes on, I've come to understand that almost nothing is impossible. It's all super interesting to think about though. The puzzle is more endless than life itself. I watched a nice little Doco about universal theory recently, I'd like to share. Go to YouTube and search for "Athene's Theory Of Everything" I'm not postulating this to be the bible or anything, but it sure made me think, holy shit! What did I just watch?

Surely we would have detected these 'Macros' by now if they are as massive as thought to be.

They've been working on this theory for more than 40 years now. So it's probably not a simple miscalculation...

One thing is for sure, Stephen Hawking said something about Black Holes that the whole scientific world would not agree. Secondly, Hawking also said that Higgs Particle would wipe us all out of kingdom come. To grind and measure this whole world of Particle Physics and the universe I almost totally find everything we read daily here in science section that nothing they say are true and factual except another one played a fool out of us from believing their fictional definition of the universe. NOTHING they say are evidence and facts except they get paid for what they do.

There's more than 5 times as much dark matter as ordinary matter. If dark matter consists of macroscopic objects made of baryons and/or quarks, and those objects are scattered evenly throughout space, wouldn't those objects absorb lots of electromagnetic radiation from stars? I can't tell if that's addressed in the paper.

You're getting warm, but think bigger still:
Dwarf-planet mass is an underestimate if cold dark matter resides in gravitationally-bound (Bok) globules of 2 to 50 stellar masses with its luminous stellar metallicity condensed into icy chondrules.
Giant molecular clouds (GMCs) of circa 100,000 stellar masses may trap CDM Bok globules from their disk-crossing halo orbits, whereupon inward diffusion of luminous gaseous stellar metallicity exceeds its condensation into icy chondrules, rendering Bok globules opaque and thus visible. Nascent stars may also sublime the most most volatile components of icy chondrules, adding to their gaseous metallicity within GMCs, and gaseous stellar metallicity lowers the speed of sound, promoting gravitational instability within Bok Globules to form stars.
So astrophysicists may have things exactly backwards: the outgassing of primordial Bok globules (in the form of 'cometary tails' and 'elephant trunks') may form and sustain GMCs, rather than GMCs forming Bok globules.
Halo Bok globules (with luminous stellar metallicity condensed into icy chondrules) = cold dark matter of galactic halos

@Terry Penrose. Hahaha... I discovered Athene's Theory about two years ago. I watched it about five times now. Very interesting and always entertaining.

I like it that theres some fresh thinking on this. Dark matter has always bothered me. There isnt the slightest trace of this ubiquitous stuff in our solar system. Ive also read that there may 100K free floating interstellar dark planetesimals for every star in the galaxy. This could account for the 5X mass issue. This makes a lot more sense.

It appears that the nature and position of dark matter has now been identified -- it is merely ordinary matter in the distant spaces between stars. See:
The Cosmic Smog model for solar system formation, and the nature of 'Dark Matter'
At: http://www.aoi.com.au/bcw1/Cosmic/index.htm
The analysis suggests that there may be as much as a billion times the mass of our solar system lying between the 100 AU boundary and half-way to the nearest star.
