CMB Haze Effect

[Guest Nim]

From Kosmoi.com/Science/Cosmology/Big Bang

 

"A critical further prediction was that the further away one looks, the hotter the universe should appear to be (as looking further away corresponds to looking backwards in time), and at some extremely distant point the radiation in the universe should be so thick as to become opaque."

 

AND

 

"In 1989, NASA launched the Cosmic Background Explorer satellite (COBE), and the initial findings (released in 1990) were a stunning endorsement of the Big Bang predictions regarding CMBR, finding a local residual temperature of 2.726 K, determining that the CMBR was indeed isotropic, and confirming the "haze" effect as distance increased."

 

Even without the CMB, wouldn't this effect still exist since the farther we look out into space the more matter we have to look threw? Kinda like how tape looks transparent when it is off the roll but becomes more opaque when its on the roll. Or how lake water looks clear in your hand but green in the lake.

 

Does the haze effect that is caused by the CMB have an official name? Also, can we see far out enough into space to find the opaque barrier that they predicted to exist? Does this barrier have a name? How do they know that the barrier isn't just a consequence of looking threw tons and tons of matter?
