We Just Picked Up an Intense Burst of 15 Weird Signals From a Distant Galaxy

Postby Phoenix76 » Thu Aug 31, 2017 7:20 am

In the early hours of Saturday morning, researchers searching the Universe for signs of alien life detected 15 explosive radio signals in the space of just five hours, all coming from a tiny galaxy 3 billion light-years away.

It's the same galaxy we've received repeated signals from in the past, but the blasts, known as 'fast radio bursts' have never been as frequent as these latest discoveries, causing the team to ask other scientists to tune in and help figure out what the hell's causing them.

Plus, the Breakthrough Listen team points out that when the pulses left their host galaxy, our Solar System would have been less than 2 billion years old - a billion years before even the simplest multicellular life began to evolve on Earth - so we wouldn't have been the most lucrative target for intelligent life out there.


Interesting concept of perhaps some alien force sending signals so many billion years ago.

I find this intensely interesting and I thank you for pointing it out, but I doubt that it's the signal of an intelligent species.

I would imagine that it's related to the gamma ray bursters that have been in the science news.

I wonder if a distant galaxy gave off a gamma ray burst...if we might not see it as a radio wave burst since a truly distant galaxy might be receeding at close to the speed of light...which would cause a gamma ray burst to turn into a radio wave burst because of the gamma radiation being red shifted.

I haven't worked out the math by plugging figures into the equations (probably from laziness), but I wonder if the original scientists took the red shifted nature of distant galaxies into account--red shifted, of course, from the continued expansion of the Universe.

Gee Gorgeous, although I don't think you can, please explain your post.

Wrong.
The continents have since repeatedly collided and been torn apart, so maps of Earth in the distant past are quite different to today's. The history of life on Earth began about 3.8 billion years ago, initially with single-celled prokaryotic cells, such as bacteria.

Except that multicellular life first appeared on Earth less than 2 billion years ago. So, not wrong.

If you're uncertain, that means you can only be a gray. Are you a member of the Illuminati? Or the Annunaki? I think you are.

Simples, the signal is Engineered. :-P

Gamma-ray bursts run to wavelengths of 10-11m or shorter, radio is meter+, so that would require at least 12 orders of magnitude of redshift. At 3 billion ly, you might get a shift from the low end of gamma to the high end of X, but that is about it. (Also too lazy to look up the formulae.)
