The Universe May Be A Sphere

800wm

From phys.org:

A trio of researchers with the University of Manchester, Università di Roma 'La Sapienza' and Sorbonne Universities has sparked a major debate among cosmologists by claiming that data from the Planck space observatory suggests the universe is a sphere — not flat, as current conventional theory suggests.

In their paper published Monday in the journal Nature Astronomy, Eleonora Di Valentino, Alessandro Melchiorri, and Joseph Silk outline their arguments and suggest their findings indicate that there exists a cosmological crisis that must be addressed.

Conventional theory, which backs inflation theory, suggests that after the Big Bang, the universe expanded in a way that was flat — two lights shone in parallel would travel forever in parallel.

But now, after studying data sent back to Earth from the Planck space observatory (which mapped over the years 2009 to 2013), Di Valentino, Melchiorri, and Silk have come to disagree with conventional thinking.

They claim that there is evidence that the universe is closed — that it is shaped like a sphere.

If you shine two lights into the dark of space, they suggest, at some point, the light would come back around to you from behind.

The researchers came to this conclusion after looking at data from the Planck observatory that showed a discrepancy between the concentration of dark matter and dark energy and outward expansion; there was more gravitational lensing than theory has predicted.

Such an imbalance, they claim, would have the universe collapsing in on itself, resulting in a sphere shape.

Others who have looked at the same data prior to this new effort have called the data from the observatory a statistical fluke.

The research trio note that there are other problems with the flat theory as well, such as scientists' inability to accurately measure the Hubble constant; each team that tries finds a different answer.

There have also been problems with reconciling surveys of with a flat model.

They conclude by acknowledging that with current technology there is no way to settle the debate — new devices will need to be invented that will be able to measure in ways not subject to debate.

Helpful Hints from joeeze: When a light bulb in a difficult-to-access multiple-bulb fixture burns out, replace them all

1201000544-l

The penny dropped for me after I ascended a tall ladder to replace a burned-out outdoor flood.

Only when I was back inside and all proud of myself did I look at my handiwork and realize I'd have to cheat death another time in the near future to replace the companion bulb in the two-bulb fixture.

Doh!

Wait a sec — what's that music I'm hearing?

Jackson Pollock — Action painting from below (through glass)

YouTube caption:

Not satisfied with black and white stills, Hans Namuth wanted to create a color film that managed to focus on Pollock and his painting at the same time, partially because he found more interest in Pollock's image than in his art.

His solution was to have Pollock paint on a large sheet of glass as Namuth filmed from underneath the work.

As Namuth could not afford professional lighting, the film was shot outdoors, next to Pollock's Long Island home.

This documentary (co-produced with Paul Falkenberg) is considered one of the most influential for artists.

In November 1950, Namuth and Pollock's relationship came to an abrupt conclusion.

After coming in from the cold weather shoot of the glass painting, Pollock, who had been treated in the 1930s for alcoholism, poured himself a tumbler of bourbon whiskey after supposedly having been sober for two years.

An argument between Namuth and Pollock ensued with each calling the other a "phony," culminating in Pollock overturning a table of food and dinnerware in front of several guests.
