Repeating Fast Radio Bursts From Deep Space!!!

No while i haven't seen it with my own eyes there are experiments, papers in peer reviewed journals and data confirming that statement available. In science you have models that are valid within certain constrains and for all intents and purposes can be proven within certain boundary conditions. Unfortunately we haven't found a general physics model that encapsulates all natural phenomena but as gravity was not defined before the 17th century, or people thought no material can withstand the effects of breaking the sound barrier before WW2 just because we do not have understanding of how things work does not mean they are not possible. There are theories and hypothesis that are put in place and as technology advances they are confirmed or disproved.

I agree with all of that. It also doesn't have anything to do with what I said.

I'm talking about the PEOPLE who use science as a dogma instead of seeing it for what it is: an ever-evolving quest for information.

Back on topic, neutron star seems plausible to me especially if the more they search for them, the more they find.

Milky Way has a lot of neutron stars and yet all FRBs are from high-redshift galaxies. Maybe FRBs are caused by Hawking radiation from primordial black holes.

Back in the day astronomers talked about blitzars (really strange objects) but now they kinda forgot about them
 
If I have taught TPU anything, I was hoping it would be how to spot a basic troll post. This thread makes me sad so many took the bait of a few.

Anyways I love topics like these. Is it Aliens? Maybe. Do I think it is......naaaaa. See from my small mind it seems pretty simple. Man cannot predict the weather. We can estimate but nothing with even 90% accuracy. This problem is literally in our backyard and something that is dyer to our survival. Yet we CAN'T understand or predict it 100% due to so many variables.

Now take this issue and multiply it an almost infinite amount. Space. How many variables between a star that's 3 light years away? Nevermind a billon. How many folds? How many gravitational fields. How many unknown or understood phenomenon's are between us and the subject we THINK we see? I LOVE science. BUT any real scientist will say IDKWTF it really is. Not until we go there and see first hand.

At this point I would like to know with 100% certainty that its gonna rain today because I just waxed my damn car.

I agree totally. But we CAN speculate. And to my small mind, I think about the fact that we've found three or four planets that meet several criteria for the possibility of being inhabitable, right in our galactic neighborhood. Thinking that way, I find it almost impossible to believe that there *aren't* any other intelligent life out there. Of the untold legions of star systems out there, statistics almost dictate that there HAS to be someone else out there. I'm not saying that this energy burst IS them... I'm just saying that someday we will hopefully find out for sure.

I imagine they're probably doing the same thing we are now... little green men wondering if there are little brown men out there in the universe.... And maybe... juuuuust maybe... sending out high energy radio waves :)
 
Philosopher Nick Bostrom wrote an interesting article on the Fermi paradox (millions of goldilocks-zone planets, yet we haven't had hard proof of aliens yet) and a hypothesis he calls the "Great Filter". You can search and read for more detail, but the summary is that there is/has been/will be loads of life out there in the universe, but life and technology develops and expands at an intelligent level in a relatively short period of time. Then with the development of stronger and stronger weapons, disease from population explosion, famine, pollution, etc. lead to mass extinction events. Who knows if it's right or wrong, but interesting to think about when looking at human civilization going from primitive life just 20k years ago to nuclear power and weapons and space travel today. That's a miniscule blip in time relative to the universe, and humans making it another 500 or 1000 years often seems like a longshot.

63 reported UFO sightings last week, 5255 sightings in the last year. Do you think they're all crazy?
http://www.mufon.com/live-ufo-map.html

US Air Force's statement on UFOs:
From 1947 to 1969, the Air Force investigated Unidentified Flying Objects under Project Blue Book. The project, headquartered at Wright-Patterson Air Force Base, Ohio, was terminated December 17, 1969. Of a total of 12,618 sightings reported to Project Blue Book, 701 remained "unidentified."

The UFOs are mostly harmless (not a threat to national security), they can't be engaged because they're too fast (can't really learn anything from them), and the Air Force was getting inundated with reports of UFOs so the military brass shut the program down giving the statement above. The USAF still fields reports from civilian aircraft, military aircraft and air traffic controllers. They do investigate sometimes as well. They are usually classified and archived and reach the same conclusions as above (harmless, can't engage, usually have RADAR data and multiple witnesses).

I know one thing for certain, Science will bear out the facts and truth of the matter in time, whether there are other civilizations out there, or primordial goo, eventually we will know as long as other things don't divide and destroy us.

One thing about all the radio bursts, is they assume other civilizations are advanced enough to create these huge devices but fail to account for the lift required to put them in orbit without destroying planets for the raw materials and to get them into a stable orbit, and the effects that would have on other planets orbits. Imagine if we mined the iron required to build planet sized arrays, what effect would it have on our own solar system.

Next is are we saying that a civilization capable of building and using such huge devices is incapable of preventing losses or minimizing losses to the point we are seeing them with such intensity at such great distance?
 
My understanding is that focused radio bursts don't require a lot of energy and can be sent from the surface of a planet. That said, we're getting ahead of ourselves. Article clearly states that the source is most likely human in nature (e.g. a high orbiting satellite). They're observing the star again now to see if they can find the signal back and to learn more about it if they do.

And remember, we're talking 11 light years away. If it was artificial, the signal could have been produced anywhere on that vector (could be closer, could be further away).
 
Really we need to establish a moon base and continue to research the same signals from there out of range from satellite disruption.

and away from microwaves..... I remember the Australians were struggling with an outer-space signal for a very long time that ended up being caused by a local microwave cooker....lol, they must of felt silly.


Strange 'outer space' signal that baffled Australian scientists turns out to be microwave oven

Yes, there's a project that plans to built a microwave/radio array on the far side of the Moon. Perfect place, moon is tidally locked, no atmosphere and no radio disturbances from Earth.

While awesome, I wonder why in the world we aren't doing this all the time. I mean... we aimed it at a star cluster 25k light years away... Which means an inconceivable amount of time between when we sent the message and when we would possibly hear back. Not to mention, while the Hercules cluster has hundreds of thousands of stars in it, it's still an infinitesimally small target in the grand scheme of the entire galaxy/universe. Compound that with the small chance that there IS indeed life in the area, the even smaller chance that there is *intelligent* life in the target area, and the ridiculously unimaginably small chance that we happen to catch someone who happens to be listening for the 3 MINUTES that the signal passes by, and is intelligent enough to recognize an ordered signal, AND intelligent enough to recognize binary when they see it, and if they even operate on the same communications and logic theory that we do. I would imagine binary would be logically universal, but then again perhaps not. The even worse part is that base10 mathematics and an 8-bit language are definitely NOT universal, they're mostly arbitrary. So how would they even recognize what the first part is, beyond gibberish? I guess maybe they would recognize the incremental nature and see a pattern. Presumably once they've cracked that first code, and also figured out the dimensions of the pattern (just as unlikely) then they could figure out the rest fairly easily.

My point is... we should be doing this ALL the time. There's no reason why intelligent life can't exist on FAR closer star systems than the one they chose out of convenience. Then again, maybe that would be a waste of time, as we would have caught their ordered transmissions by now (much like the subject of this thread.)

EDIT: Totally random, but is it just me or does the place in the first picture in the link look like it should be in a Bond movie?

Meh , chances are there is no one that can listen to those signals regardless. The way the messages are encoded is not that problematic , every intelligent life that figured out radio wave communication would eventually figure out the fundamental binary aspect of information too. These are the most basic methods of encoding data , not the most complicated ones , one should in fact expect that these are the most common ones. The idea isn't that such messages need to be understood. The main point is to get across something that is of artificial nature.

The Arecibo message was the only one I'd heard of(until today). I guess I should have taken the time to read the entire wiki link before posting it. Specifically the See also list. Where you'll find the link to the Active SETI page. On which you can read about other transmissions. One of them having already reached its intended destination in 1999. Many of the others will get to where they're going relatively soon as well.

It's aliens.
 
Iirc sunspots can create radiowaves too.

dont forget there is the chance that our signal will be reflected back at us and never reach intended target.
