New insights about the brightest explosions in the Universe:
Swedish and Japanese researchers have, after ten years, found an explanation to the peculiar emission lines seen in one of the brightest supernovae ever observed—SN 2006gy. At the same time they found an explanation for how the supernova arose.
Superluminous supernovae are the most luminous explosions in the cosmos. SN 2006gy is one of the most studied such events, but researchers have been uncertain about its origin. Astrophysicists at Stockholm University have, together with Japanese colleagues, now discovered large amounts of iron in the supernova through spectral lines that have never previously been seen either in supernovae or in other astrophysical objects. That has led to a new explanation for how the supernova arose.
"No-one had tested to compare spectra from neutral iron, i.e. iron in which all electrons are retained, with the unidentified emission lines in SN 2006gy, because iron is normally ionized (one or more electrons removed). We tried it and saw with excitement how line after line lined up just as in the observed spectrum," says Anders Jerkstrand, Department of Astronomy, Stockholm University.
"It became even more exciting when it quickly turned out that very large amounts of iron were needed to make the lines—at least a third of the Sun's mass—which directly ruled out some old scenarios and instead revealed a new one."

Umm, false flag op on liberals? Ok, this country is fucked, you assholes will gladly overlook election fraud if 'your' team wins and we'll slide into a full blown fascist state. Fucking awesome /s

Yikes. It's only January. It's going to be a long year.

It has been a long 3 watching a criminal conman run the country. If someone like TMB can't live up to the most basic character principles he claims to embody, then I don't see any hope for the country when criminals like Trump are allowed to subvert the system. There has already been widespread voter suppression and fraud, if Trump is given a pass it will only get worse. We have plenty of examples of sham democracies and the US is heading right there.
The insidious part is that the fraud is only required in key places due to the electoral college, so the fraud doesn't have to be so widespread it would be likely caught somewhere. Yay voting machines! Yay lax security! Yay dictatorship!!! Barf
