Supervoid


The image above is a cosmic microwave background radiation map of the universe, bright colors hot, dark colors cold. The circled bit at the lower right is a part of the sky deemed too large and too cold to be easily explained by science.

The reason I'm posting this is because of one sentence in the explanation of the map and the CMB cold spot on the Astronomy Picture of the Day, where I found it. The sentence is this:

Published speculation has included spectacular progenitor hypotheses that involve a supervoid, a cosmic texture, or even quantum entanglement with a parallel universe.

These are actual scientists speculating about this, not addled callers to Coast to Coast. I'm not saying I understand what that sentence even means. But it sure is fun to read.

so the CMB cold spot is hell?

better alert NASA.

and the Pope.

Nope, the CMB is a ribbon of Daath. Hell's a travelin' fool. Get your facts straight. ;-)

It's really only comparatively cold.

It can't be colder than -273'C or whatever Kelvin is. We're not much above that in our narrow comfort zone.

I wonder what the hottest temperature in the universe is. If there is a mysterious hot spot somewhere out there.
