“Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before.” -Edgar Allan Poe
No matter where you look in the night sky, a powerful enough telescope appears to reveal points of light. Even if you find a region with no stars in the Milky Way, you’re likely to find thousands of galaxies in the deep sky beyond, as the Hubble Deep Field and successor images demonstrated. However, it wasn’t until 2010 and the WFC3 that we were able to get deep, wide-field views simultaneously.
“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small." -Neil Armstrong

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 just as REAL ph
