"Sexism was the only thing that kept Jerrie Cobb out of space in 1960, and it cannot be allowed to stand in her way now." -Patricia Ireland It isn't every week that you cover topics ranging from the birth of the Universe to the fundamental nature of space, and the go from sexism in NASA to the anthropic principle to. the math of reality television. But all that and more was on tap this past week at Starts With A Bang, with new articles on: ....
"Some say the world will end in fire, Some say in ice. From what I've tasted of desire I hold with those who favor fire. But if it had to perish twice, I think I know enough of hate To say that for destruction ice Is also great And would suffice." -Robert Frost Depending on where you are in the world right now, you might really be feeling the effects of the emerging winter, as cold snaps, freezes and snowstorms take hold across the northern hemisphere. ....
“I took a deep breath and listened to the old brag of my heart. I am, I am, I am.” -Sylvia Plath It's been two weeks since our last edition of our Comments of the Week, and from the heartbreaking to the mystifying, there's a lot we've written about and explored together. If you missed anything, go ahead and take a look back at our amazing suite of articles over that time: ....
Image credit: The Cosmic Perspective / Jeffrey O. Bennett, Megan O. Donahue, Nicholas Schneider and Mark Voit. From Azri our original question-asker on the topic of how long the Universe has been accelerating: Just when you mentioned that the universe was almost 7.8 billion years old when started accelerating: I think that calculation is based on a constant” cosmological constant! what if Dark energy was dynamical !? can one expect more than 8 bill years, lets say almost recently! If dark energy changes over time which it may then it s conceivable that the Universe began accelerating either slightly earlier or later than this. If dark energy was weaker in the past and is stronger now, then the Universe will have been accelerating for ....
and then as March goes on, I ll have an exclusive interview with the Principal Investigator of LIGO, Dave Reitze (so drop me your questions here!), I ll be giving public talks in Portland, OR and in Memphis, TN at MidSouthCon, and then we have some even bigger events coming up in the spring! But there s no reason to dawdle any further; there s some great science to dive into right now on this edition of our Comments Of The Week! Image credit: NASA. real and virtual gravitons: If I am understanding correctly, there is a gravitational pull between any two massive bodies and that gravitational pull is facilitated through VIRTUAL gravitons. The radiation of VIRTUAL gravitons does not consume any energy or mass from either of the massive bodies and so the gravitational field could theoretically persist until the end of time. [.] However in the merger of black holes some energy is turned into REAL graviton particles and those should exhibit the particle-wave duality jus ....
