Bold should be: ...we believe only 700 million years after the cosmos was potentially born in what we believe (and many do not) was something we call the Big Bang.
Astronomers know two processes that form the dust, Krause said. One, old sun-like stars near death generate dust. Two, infrared space missions have revealed the dust is produced in supernovae explosions.
Bold should be: Astronomers used to believe there were two processes that form dust, but now we realize we were wrong, which seems to be happening on more of a regular basis.
"The first process takes several billion years," Krause noted. "Supernovae explosions, by contrast, produce dust in much less time, only about 10 million years."
Bold should be: The first process we thought took several billion years, but now we realize, that our juiced up numbers to pull the line for the Theory of Evolution, we miscalculated.
More insightful commentary to come!
FWIW, the astronomical time scales have nothing to do with evolution. It's all based on geometry and the speed of light. We can measure the distance to the nearby stars (~500 light years away or so) via parallax. Beyond that, we can use the period-luminosity relation of variable stars to measure out to a few million light years. After that, redshifts are involved and things get a little wonky.
I was reading through your posts archive. This particular one I found very entertaining. Keep up the good work.
