“I heard police or ambulancemen, standing in our house, say, “She must have provoked him,” or, “Mrs Stewart, it takes two to make a fight.” They had no idea. The truth is my mother did nothing to deserve the violence she endured. She did not provoke my father, and even if she had, violence is an unacceptable way of dealing with conflict. Violence is a choice a man makes and he alone is responsible for it.”
No but there’s this one interview where he says basically “People won’t listen to you or take you seriously unless you’re an old white man, and since I’m an old white man I’m going to use that to help the people who need it” This guy is amazing.
A Redshift Lookup Table for our Universe Image Credit: Sergey V. Pilipenko (LPI, MIPT)
Explanation: How far away is “redshift six”? Although humans are inherently familiar with distance and time, what is actually measured for astronomical objects is redshift, a color displacement that depends on exactly how energy density has evolved in our universe. Now since cosmological measurements in recent years have led to a concordance on what energy forms pervade our universe, it is now possible to make a simple table relating observed cosmological redshift, labeled “z”, with standard concepts of distance and time, including the extrapolated time since the universe began. One such table is listed above, where redshift z is listed in the first and last columns, while the corresponding universe age in billions of years is listed in the central column. To find the meaning of the rest of the columns, please read the accompanying technical paper. Although stars in our galaxy are effectively at cosmological redshift zero, the most distant supernovae seen occur out past redshift one, which the above chart shows occurred when the universe was approximately half its present age. By contrast, the most distant gamma-ray bursts yet observed occur out past redshift six, occurring when the universe was younger than one billion years old, less than 10 percent of its present age.
Little known fact about me. I studied Astrophysics during my first three years of University, before abandoning academic pursuits of the sciences in favor of the cinematic arts. But I still love astronomy. The name of my wifi network at home is “The Redshift” and this is what that means.
