'Dark Matter; Its Source'

Quantum Science is a Paradox, but here goes as a working doc. What I do is to look for as much information as possible and then try a best fit.  
Scientists will spend billions to do the same thing.  
 
This concept has the most beautiful symmetry.  
   
Where has all the light gone?  
Not enough microwaves.  
 
If there was the Universe would be a lot hotter heating up those few hydrogen atoms per cubic meter.  
 
You cannot destroy energy without an equal and opposite result.  
So the Universe should be hot and bright.  
 
Of course the Universe might not be finite and leak into the medium surrounding it. Pigs flying by?  
   
Add up all the energy from the Stars for all time and that is a lot. Where has it gone. Any ideas?  
 
One idea;  
 
Light traveling from different sources creates interference and photons are eliminated to produce black lines and...?  
 
Energy cannot just disappear...what is produced at the interference point? Dark Matter?  
 
We see that with two sets of ripples on a pond where they cancel each other out.  
 
What is there supposed to be a lot of in the Universe?  
Dark Matter!  
 
So to the mathematicians out there, a question.  
 
Is the weight of dark matter in the Universe equal to all of the light and other vanished radiation in terms of E+MC2 since the beginning?  
 
Otherwise we would be cooking in our socks!  
 
Is the expansion of the Universe due to this conversion?
