Cosmic Cold Spot Just a WMAP Data Artifact

What! No Parallel Universe? Cosmic Cold Spot Just Data Artifact |
Universe Today
"Rats! Another perplexing space mystery solved by science. New analysis
of the famous "cold spot" in the cosmic microwave background reveals,
and confirms, actually, that the spot is just an artifact of the
statistical methods used to find it. That means there is no supervoid
lurking in the CMB, and no parallel universe lying just beyond the edge
of our own. What fun is that?"

They indicated the "cold spot" had a star "in front" and "behind".
How in the world do you have a star "behind" a supervoid at the edge
of the Universe, and us able to see it? Not that this result is
surprising, just wondering about that little datumn...

Pity.

I continue to be somewhat irritated at how well our simple cosmological
models work.

Eric if you continue to be somewhat irritated why you
have not received your long overdue BSc yet, that
mentality in your notion you just expressed may very
well be the reason for it.

OTOH you may be a very rare character and you may
gain fame in some profession wherein the guiding
principle rules that simple solutions are discarded
for more complicated ones.

You'd make a good bureaucrat... or maybe
you are the Anti-Occam... sort of an Anti-Christ.

Thansk for the laughs, dude,... ahahhahanson

I know that these cold and hot spots in the
cosmic microwave background are LIGHT CONES.
(I refer here to the WMAP picture).

I think you're confusing light-cones with ice-cream cones. *They* are cold.

Why it's the identical but evil twin star in the parallel universe, of
course. :-)

Pity, that it turned out to be just a data artifact? Or pity that it
blows some favoured model of the universe out of the water for you?

Well, obviously this particular model didn't work.

Based on his next comment, it is a pity that "vanilla" GR is
sufficient... again.

There was no model to support this. It flew in the face of
classical mechanics and multiverse cosmology both.

Can't you understand GR.

Intersection of ball and cone is SPOT. This is how we observe spot.

Lot of spots means lots of light cones and there seems to exist
two types of light cones. Perhaps these two types of light cones
corresponds two different types of mass which exist ???

Please take a look Ned Wright's cosmology tutorial to see how
we observe in GR.
