New Findings Deepen the Mystery of Fast Radio Bursts
An anonymous reader writes: Last week, it was reported that the mystery of fast radio bursts were solved, and that they were due to the merger of a neutron star with another collapsed object, well outside of our galaxy. However, not only was that analysis fundamentally flawed, but a new paper out today identifies fast radio bursts that repeat, a dealbreaker for the merger scenario. Instead, it's thought that these events come from the evolution of young neutron stars, as the data show an extragalactic but non-transient origin for these bursts. Planned follow-up observations plan on identifying the source locations as well as their true nature, and discerning whether all fast radio bursts have the same origin, or whether there are multiple different classes.

Do we know this isn't gravitational lensing? (https://en.wikipedia.org/wiki/Gravitational_lens)
These are just the microwave ovens...
Feh, sounds like intergalactic war to me.
deserve's got nothing to do with it...
The Fermi Paradox pokes some pretty large holes in your theory.
Occam's Razor encourages us to look for more ordinary explanations first.
If it weren't for deadlines, nothing would be late.

Yes, if we apply Occam's Razor, we can deduce that this is just Zorlax the Mighty trying to connect on LinkedIn.

The Fermi Paradox only applies to civilizations in our own galaxy, not to events happening billions of LYs away. There are plausible explanations for why civilizations might be rare in our own galaxy, yet common in other galaxies. For instance, a hypernova about 4 billion years ago may have sterilized much of the Milky Way, exterminating life on many planets that could have gone on to evolve intelligent beings.

Occam's Razor is a good rule of thumb for respectable scientific hypotheses, not for speculative conjectures on Slashdot.
I would expect that when a ship transitions into or out of warp drive, it would cause something like this focused tightly along the path of travel.
And you expect that based on... what? A few seasons of TNG and BSG?
My guess is that this is the cause of these events and a clever scientist...
...would have a better theory.
systemd is Roko's Basilisk.

It does no such thing! Occam's Razor simply states that when encountering two (apparently) equally effective models to explain an unknown, it is preferential to assume the mathematically simpler is accurate until it is found to be flawed.
However, some Cult-like misunderstanding of his statement seems to be the defining philosophical dogma of an unfortunate amount of otherwise educated and often rational individuals. I've seen people arguing for a disproven model over a more complex one that continues to fit observations "because Occam's Razor."
The only scientific hypotheses I respect are the ones derived from speculative conjecture on Slashdot. Everything else is just theoretical wankery.
Possible explanations first yes, but not at the exclusion of exploring all possibilities.

Can we, or have we mapped where these are coming from?

That's not true, you have fantastic tranny factories as well.
There seem to be a gigantic particle accelerator somewhere close to the center of the Milky Way:

You basically just repeated what the parent post said. The simpler explanation is the more ordinary one that requires the least unproven assumptions.

I'm not saying it is aliens, but it is aliens.
Everyone knew the world was round, if you live near an ocean it's very hard not to notice. Columbus just thought it was half as big around as everybody else did, so they predicted he'd starve before he reached India.

The paper from the actual researchers is far more guarded, and suggest that it may be EMI similar to Perytons, which are radio sources that appear to look like a pulsar signature.
From Wikipedia - "In 2015, Perytons were found to be the result of premature opening of microwave oven doors at the Parkes Observatory. The microwave oven releases a frequency-swept radio pulse that mimics an FRB as the magnetron turns off.[2][10]"
http://arxiv.org/pdf/1503.0524...
Here is a paper on Perytons, and their possible sources: http://arxiv.org/pdf/1404.5080...
Here is a link on Pulsar physics, including a very basic back of the envelope derivation of the dispersion medium of pulsars. Apparently two pulses from a pulsar are detected a few milliseconds from one another, and stem from the mass difference between the electron and a proton and their interaction with interstellar space. Still trying to get a handle on this.. http://www.cv.nrao.edu/course/...

Revisionist history much?

No, not at all. Google Eratosthenes.

To be fair warp drive is being speculatively thought about and some models would produce a flash. See the serious overview for example https://www.youtube.com/watch?... "Warp drives and bending time Prof Tamara Davis" Australian Academy of Science. "It could be that the optic boom of arrival at the destination would fry the destination" "The energy required to operate the drive could exceed that contained in the mass of the observable universe"
However the energy currently thought to be involved in a FRB is way outside anything human civilization could do - e.g. Wikipedia records the energy of one FRB as "The power exceeded 1.3×10*42 ergs/s. That is estimated to be as much energy in one millisecond as the Sun emits in 10,000 years"
So it is not likely to be warp drive given what we understand.
Facts are history now plebs have politics for religion on social media.
No, if you go there and check, it turns out India is not in the Caribbean.
However, not only was that analysis fundamentally flawed...
That's not possible. I read it on /.

Yes. Everyone thought Columbus was crazy, that is why he got government support for a really expensive expedition.
He seems to have a better grasp than you do:
As far back as the 3rd century BC, Eratosthenes had correctly computed the circumference of the Earth by using simple geometry and studying the shadows cast by objects at two different locations: Alexandria and Syene (modern-day Aswan).[30] Eratosthenes's results were confirmed by a comparison of stellar observations at Alexandria and Rhodes, carried out by Posidonius in the 1st century BC. These measurements were widely known among scholars, but confusion about the old-fashioned units of distance in which they were expressed had led, in Columbus's day, to some debate about the exact size of the Earth.
Toscanelli's notions of the geography of the Atlantic Ocean, which directly influenced Columbus's plans
From d'Ailly's Imago Mundi Columbus learned of Alfraganus's estimate that a degree of latitude (or a degree of longitude along the equator) spanned 56 miles, but did not realize that this was expressed in the Arabic mile rather than the shorter Roman mile with which he was familiar (1,480 m).[31] He therefore estimated the circumference of the Earth to be about 30,200 km, whereas the correct value is 40,000 km (25,000 mi).

~ People that think they are better than anyone else for any reason are the cause of all the strife in the world.
And those aren't the biggest issues considering the inside of the bubble experiences radiation that diverges when travel exceeds c, and the bubble is causally isolated from the inside, so you would need it to be generated by stuff in front of it...
And Columbus would have starved too, if there wasn't a continent in the way.
The age of enlightenment lie by excellence. Since they were so "enlighted" then the previous age must have been dumb idiot. Thus the myth cropped up that people thought the earth was flat. Actually among the scholar and sailor (those who count with respect to this myth) they knew and were taught the earth was a sphere, and had pretty good estimate back in the ancient greek world. As for the paysant/serf who know what they taught beyond "will I have bread tomorrow".

Whoosh.
No, you completely misunderstand. It has nothing to do with "unproven assumptions," it purely has to do with the mathematical complexity of an issue. Occam's Razor has nothing to do with trying to explain why something does what it does, it is purely in the scope of modelling the behavior of what something does. Everyone (like you) who tries to apply it beyond that is delving into the realm of incompetent hard-dogma philosophy.
