Earth receiving mysterious radio signals
- tomrod 12y agoMuch like many things: cool if true, and I wonder what's behind it. (e.g. Bloop, EM Drive, etc.)
- modzu 12y agothey suggest it could be a cell phone tower :(
- recondite 12y agoJust don't forget, the primer is 3-dimensional: https://www.youtube.com/watch?v=HgPSUer1ujM https://www.youtube.com/watch?v=HgPSUer1ujM There, I just saved us like a week's worth of effort.
- rustyconover 12y agoWe just have to think like a Vegan. No meat, no dairy, no animal products. And intergalactic wormholes.
- kposehn 12y agoBecause once upon a time, we were each a hell of an engineer.
- rustyconover 12y agoCould Elon Musk have launched something with SpaceX that is faking these signals, so he could fax down plans for Tesla's new teleporter to be unveiled at the end of the month? Conspiracy hat engaged.

- sytelus 12y agoThis is very interesting paper that just came out last week. So they found fast radio bursts (FRB) to have DMs (Dispersion Measure) that are in perfect multiplication with integers to a constant. This was supposed to be bit more random and so these being in such order is very surprising and unlikely to be just coincidence. Only 11 FRBs are found so far which might also means source of signal is not all around. On the downside, the signal were assumed to require huge amount of energy in short burst that Sun would produce in entire day. That assumption lead to belief that FRBs were too close to be in our Milkeyway and more likely to be in other galaxy. Overall very interesting development.
- pg_is_a_butt 12y agojesus... i hate that people can say whatever they want here and be bumped to the top. spreading idiocy isn't helpful. stay quiet. "perfect multiplication with integers to a constant"... first off... it was 187.5... not an integer. 2nd... it wasn't "perfect" in any way... the measurement points fell STATISTICALLY on the 187.5 multiplier line, but some were well off the line, and others high or low. pulsars in a system with fast orbiting planets currently inline with earth could explain such patterns. you are unlikely to be an astronomer. on the downside, you don't seem to care.
- cpncrunch 12y agoNo, they're not -- read the paper. You'll see that the DMs are close to multiples of 187.5, but not exact. In fact some are quite far off (5%). I'm slightly dubious of the paper. I haven't calculated the probability myself, but is the 1/10000 chance calculated from assuming they are exactly 187.5 multiples (DMest), or from the actual results (which aren't exact multiples)? I'm hoping it's the latter.

- dfryer 12y agoThe paper is much more conservative than the article about it. They're saying that the close relationship between the signal and the human-made second, plus the fact that most of these signals were observed at one particular telescope, suggests strongly that it's a local, human source. "Paper doesn't rule out aliens" isn't a particularly strong statement. I've read many papers that don't rule out aliens, dragons OR unicorns.
- dchichkov 12y agoThe paper starts with: "Eleven FRBs have been detected so far, nine with the Parkes and one at the Arecibo telescope." That arithmetic is wrong. Tongue-in-the-cheek - April's fool? edit: it actually seems more like a genuine typo in a pre-print. The list further in the article contains 10 FRBs from Parkes. edit 2: linked to the abstract. http://arxiv.org/abs/1503.05245 http://arxiv.org/abs/1503.05245
- cpeterso 12y agoThe eleventh could have been detected somewhere else.
- Sniffnoy 12y agoA note -- if you're linking to arXiv, it's better to link to the abstract (http://arxiv.org/abs/1503.05245 http://arxiv.org/abs/1503.05245) rather than directly to the PDF. From the abstract, one can easily click through to the PDF; not so the reverse. And the abstract allows one to do things like see different versions of the paper, search for other things by the same authors, etc.
- lotsofmangos 12y agoIs always a good idea to not rule out aliens, just in case. Especially aliens with elaborate senses of humour. It might explain a lot.

- soheil 12y ago"Failing some observational bias, the suggestive correlation with terrestrial time standards seems to nearly clinch the case for human association of these peculiar phenomena." It's just from the latest NSA microwave oven.
- itistoday2 12y agoTold you! Aliens be at it! 👽 </dives> EDIT: Hah! Your lack of humor has no power over my emoji aliens!! Hahahaha! 😄👽👽
- capex 12y agoFirst I double checked if 1st April has passed.
- KamiCrit 12y agoWow!

- houseofshards 12y agoWhat does the article mean by "fast" radio signals ? Don't radio waves always travel at the speed of light ?
- JonathonW 12y agoThey're "fast" in that they only last a short period of time-- these signals only last a few milliseconds, and they're rarely detected in real-time.
- justinpombrio 12y agoSo... brief.
- gre 12y agoThey mean the signals last about a millisecond.
- IndianAstronaut 12y agoThis has me curious as to how much radio data from space remains unanalyzed? There is probably more data being received than the select group of scientists working on this can analyze. How much machine learning power has been directed at this?
