When Stars Collide
A few paragraphs from my book, “When Stars Collide” (working title)
This is the realm of multimessenger astronomy, the amalgamation of instruments each designed to witness a cosmic event though a unique point of view. Not unlike seeing the human body from the outside, optical light refracting from clothing and skin, an x-ray image looks past the superficial to the inside. Add ultrasound, CAT, and fMRI and we have a multimessenger means to probe the interior as we do the vast exterior of the cosmos with telescopes.

What makes astronomy so exciting is that while you anticipate one thing, you are often met by another. It is not that the laws of physics are being broken, rather that our understanding of the laws is being challenged and expanded. What we did not expect catches us off guard, keeps us humble, and reinforces a childlike sense of the mystery and magic of the incredibly vast universe in which we reside.

Franco was annoyed that I had not kept up with the LIGO email lists, that we could not reflect on this together. I realized my mistake, for I had missed the live unfolding of something extraordinary. But what we didn’t know then was that just three days later there would be another detection event, this one a total game changer.

This confirmed that the signal was real. It could be seen with an unaided human eye above the background noise in the data from both Hanford and Livingston. At that point, all skepticism disappeared and a chant erupted in the telecon chat: “Send the alert!” “Send the alert!” “Send the alert!”
The alert went out to hundreds of astronomical observatories around the world, partners who had for years waited for just such an opportunity. This started it all. This was the birth of multimessenger astronomy.
