Ben Tippett gives us his take on it.
Hi!LIGO just announced detecting.1. gravitational waves2. colliding black holes 1.3 billion years away.this is just me talking about my feelings about it.

Abstract: Learned et. al. proposed that a sufficiently advanced extra-terrestrial civilization may tickle Cepheid and RR Lyrae variable stars with a neutrino beam at the right time, thus causing them to trigger early and jogging the otherwise very regular phase of their expansion and contraction ...

It's fascinating that now we always have to take into account the possible involvement of intelligent beings when observing astronomical phenomena. David Deutch wrote quite a bit about this in his book The Beginning of Infinity .

There it is. Of course, all the MSM reporters will be poring over it all afternoon before they write their stories....
Gravitational waves emitted by the merger of two black holes have been detected, setting the course for a new era of observational astrophysics.

It seems as if the #LIGO rumors were essentially true.

Gorilla fossil suggests split from humans as far back as 10 million years ago
(Phys.org)—An international team of researchers studying fossils unearthed in Ethiopia's Chorora Formation in the Afar rift has dated some gorilla teeth fossils to approximately 8 million years ago, which the team suggests, shows that the human gorilla split had to have occurred at least 10 million years ago. The team has published a report of its findings and theories in the journal Nature.

I get from SIMBAD that there are 418 stars within our two-way microwave sphere (starting at Battle of Britain), excluding white dwarfs and brown dwarfs. Only 21 of those are G class. Should probably also exclude flare stars. Of course, this number grows faster every year.

Thomas at CDF helped me get my SIMBAD query right. If you want to exclude Brown Dwarfs, use maintype, not 'otype' Thanks, Thomas!

Graviational waves

The rumors are true: LIGO has seen gravitational waves! Based on the details of the signal detected, the LIGO team estimates that 1.3 billion years ago. two black holes spiralled into each other and collided. One was 29 times the mass of the Sun, the other 36 times. When they merged, 3 times the mass of the Sun was converted directly to energy and released as gravitational waves.

For a very short time, this event produced over 10 times more power than all the stars in the Universe!

We knew these things happened. We just weren't good enough at detecting gravitational waves to see them - until now.

I'll open comments on this breaking news item so we can all learn more. LIGO now has a page on this event, which is called GW150914 because it was seen on September 14th, 2015:

http://www.ligo.org/science/Publication-GW150914/index.php

You can see the gravitational waveforms here:

At left in blue is the wave detected in Livingston, Louisiana. At right in red is the wave detected in Hanford Washington. The detector in Hanford saw the wave a few milliseconds later, so it must have come from the sky in the Southern hemisphere.

Open source is now ready to directly compete with Mathematica for use in the classroom
When I think about what makes SageMath different, one of the most fundamental things is that it was created by people who use it every day.  It was created by people doing research math, by people teaching math at universities, and by computer programmers a...

Introduction
Feel free to circle me, but if you want me to circle you back, then please have some content in your profile, use your real name, and provide some information on who you are, and some clear indication of what interests you. Please don't use a stock photo fro your profile pic - that's a red flag.

I suffer from a low curiosity threshold.  I am a space systems engineer, blogger, podcaster and a skeptical but open-minded investigator.   Especially interested in space, astronomy, and the search for intelligent ETs.  Although most of my G+ posts are science or space related, I also spout off on music from time, totally unqualified though I am.

My two closely related podcasts are: Unseenpodcast.com and wowsignalpodcast.com. To join the panel pool for the Unseen Podcast, please visit the Participant's Community and knock on the door. We usually record Friday nights on the East Coast of the US
