When researchers reanalysed the gold-standard data set of the early universe, they concluded that the cosmos must be "closed," or curled up like a ball. Most others remain unconvinced.
A provocative paper published today in the journal Nature Astronomy argues that the universe may curve around and close in on itself like a sphere, rather than lying flat like a sheet of paper as the standard theory of cosmology predicts. The authors reanalysed a major cosmological data set and concluded that the data favours a closed universe with 99% certainty — even as other evidence suggests the universe is flat.
The data in question — the Planck space telescope's observations of ancient light called the cosmic microwave background (CMB) — "clearly points towards a closed model," said Alessandro Melchiorri of Sapienza University of Rome. He co-authored the new paper with Eleonora di Valentino of the University of Manchester and Joseph Silk, principally of the University of Oxford. In their view, the discordance between the CMB data, which suggests the universe is closed, and other data pointing to flatness represents a "cosmological crisis" that calls for "drastic rethinking."
In your opinion, which shape is more likely ?

Plasma is a damn good absorber. That's the point.

Oops, ignore that post; I somehow thought you had answered another post of mine.

Plasma is a lot hotter than modern LCD sets, which are also much cheaper.
