I love how KZread just became an enormous story telling machine - science is good for my curiosity, and having it told by a friendly face is so much better than all those overdramatic, oversimplified TV documentaries where every single sentence of a scientist is buried under a dozen silly sentences spoken by some off-screen voice, interrupted by silly music, and a moving camera for no good reason. Dr Becky could read me the phonebook, and it would still be better than all that attention grabbing shit and clickbait. Seeing and hearing her tell a scientific story is not only feeding my curiosity, it‘s also calming my emotions and helping me relax after work / before sleep.

I think you just became my new favourite science channel. Subscribed.

I really enjoyed this. I hope you add more videos to this series soon.

Often wondered about these. Great vid, thank you!

A Dr. Becky video a day will keep the dumb at bay. So glad I came across your channel. Ty you rock Doc!

Interesting video. Thanks! FRBs seem to be in fashion these days. (Glad you mentioned GRBs (gamma-ray bursts) too.) The video was informative and I liked the discussion of the possible theories/theoretical models for FRBs.

You always have great stories and a way to simplify complex subjects. A suggestion going forward would be to not say "over and out". On a radio "over" means your turn to talk. "Out" means the conversation is done and you are signing off. So "over and out" means "your turn to talk AND we're done talking". I always look forward to your videos. Thank you.

Excellent!

I was expecting to see at least one million subscribers to this channel. I was unpleasant surprised when I saw only 30K subs. I hope you will continue to spread your knowledge for us little people. Thank you and best wishes from Croatia.

Hadn't seen this one yet. Awesome video!

Great stuff, thanks.

Superb!! Thank you :)

That meerkat image looks fascinating. There's just so much going on. As I understand, the origin of those filament structures is still unknown? How much more do we expeced to be able to see with the event horizon telescope?

Love your channel

Love your vids, can watch them for days!! A big puzzle for me is how we still pick up the comic microwave background for near the beginning of the universe. It radiates out (into what?) and should have past us already. Or even wondering how we could ever have gotten in front of it. I can't make it work in 4 dimensions in my head. (p.s. excuse my grammer!)

great video, just found your channel

PART 2 Please!!!! Since FRB 180916.J0158+65 is causing so much buzz even in mainstream media.

I enjoy your channel very much. You have a great ability to make sense of such complicated subjects. I love space and all it’s secrets. It’s amazing how enormous the cosmos really is. Imagine the things we haven’t even discovered yet! I hope someday we have the ability to travel outside our solar system. And see first hand what a black hole really looks like. Watch the birth of a star or visit another earth like planet. It amazes me how complex our universe is. Thank you for the great videos

This was a very interesting video and I quite enjoyed it, but how did the contributions (and projected expectations) of the CHIME array, especially with regard to its discovery of a R(epeating)FRB in the north polar sky not warrant mention? Also, your description of the Blitzar left me to wonder if that's another name for a Strange (Quark) Star?

Hi Becky, I see you fixed the camera focus issue but there's still some distortion in the audio, so can you try getting a better microphone please? If you don't know what I'm talking about listen at 5:05 where it's really bad. There's also some echo from the walls but that's not as big of an issue (to me, might be worse to others). I'm only complaining about this because otherwise I really love these videos and hope you keep making them! Also I only found your channel from a random comment you made on the last deep sky video. If you want more viewers can you get Brady to give you a shout-out in one of his videos?

The narration/explanation is fine as far as it goes. I struggle with understanding the graphic charts (if that's what they're even called). Could stand some explanation why they're used with the units on the x & y axes, etc..

I hope the mystery goes on a while, love a good mystery

I really enjoy your channel, Doc Becky, not the least those out takes at the end...Dr. Becky 'Unleashed!' Some FRB signatures look good and some make me suspicious about the narrow bandwidth and linearity. Satellites and some UAVs use chirp radar altimeters and these wont be the same as aircraft radar altimeters. Aircraft have a faster sweep by far than the FRBs you show and mostly work at 4200-4400 Mhz. Still, like lunchtime microwave ovens, some satellites and UAVs might be masquerading as FRBs.

Not everything. (If humans had evolved in our galaxy, several hundreds of billions of years in the future, rather than now; we would have no way of ever discovering that the universe had a beginning, as there would be no other galaxies visible to us. We would probably believe that the universe comprised of the Milky Way only and had been here forever. There are probably mysteries we can't even guess at..)

Yeah, those Microwave Oven FRBs.... Here it sometimes happened that I went to cook dinner while my 13cm amateur radio station is on, and heard the receiver open while in the kitchen. The oven produces enough products on 2320 MHz to explain that...

You rock! Science woman.

Haha, hella, that's some 415 right there

Dr. Becky, so, would the WOW signal be considered a FRB? or is there not enough information to make this determination. I realize it's a transient event however was just wondering. ;)

Now, the frequency sweep, could that be a chirp due to dispersion in the inter(planetary|stellar|galactic) medium? It shouldn't be quite so sharp if that's the case, I think; but I don't know much about dispersion of such media. Would be interesting to see articles or videos on it!

Very interesting. One thing that strikes me: how do we know that all these phenomena are caused by the same type of event?

Maybe it is focused and not spreading much which would make it short as the beam passes over the antenna. Maybe lensing of high energy signal closer to the source of the high energy events focuses it like a lenses.

Dr. Becky, Has the possibility of a magnetar star, going through a magnetic quake realignment with the magnetic pole alignment focused at the earth, been considered in the science community?

I love you Dr Becky 😍♥️😍♥️😍♥️😍♥️😍♥️😍♥️

Just a wild idea, buy maybe the magnetar is forcing a highly ionized gas to swirl and rub particles together collecting massive amounts of static charge? So perhaps those radio bursts are gigantic lightning discharges from the staticly charged gas, grounding on the magnetar in a split second? That would be cool. :)

Dr Becky, if possible, could you tell me why we have ruled out FRBs being the hawking radiation generated from final stage black hole evaporation. I did a bit of calculation and found decaying black holes can still possibly explain a lot of what we are observing; even, repeated FBRs; particularly when you consider the effects of the gravity of such black holes in increasing the hawking radiation pulse. It possible to explain repeat FRBs through hawking decay with other simple phenomenon like galactic black holes accumulating numerous small black holes in slow decaying orbit that lasts long enough for the small black holes to periodically evaporate as an FRBs. Thank you

Who is the better teacher? Dr. Becky or Prof. Meghan Gray?

Is that energy estimate based on the source radiating in all directions? If it's well focused then it might be a lot less. Maybe it's the aliens version of Project Starshot :-)

I've heard somewhere that neutron stars have "crust" structures. Could it be that when the "crust" breaks, a large amount of energy is released causing FRBs?

What particularly tickles me about the topics in this video is that report about microwave ovens. It may seem trivial and perhaps even embarrassing to write such a report, but I suspect that it is in fact a pretty important study in how to find and eliminate sources of faulty data.

Becky, you are brilliant, articulate, an amazing educator, energetic...all things we all know and love and don't need to express. You need a better Microphone. Please. It's a really important component to your presence. I wish it weren't critical for this media, but it is and I would hate your wobderful videos to not reach a greater audience over such a trivial, seemingly superficial detail.

5:42 That's so funny! I guess they must have been in a hurry.

I think there was a recent paper on these, they localized one pretty much

It’s like when you have the collapse to a black hole it happened so quickly that the space-time fabric is in effect snapped back to fill in the space and that generates the RF burst. You could have an object it’s fluctuating between being a black hole and a pulsar going back-and-forth, Interesting

Having the staffs lunch/dinner detract from relevant data collection saddens me. Love the channel.

Yeah. No hungering for knowledge among that lot.

I wonder sometime if it is possible for particles to gain energy directly from Gravitational Waves. What I mean by that is a kind of particle "surfing" on the Gravitational Waves. I wonder if the particles themselves can gain back some part of energy from Gravitational Waves. Maybe this would be the case with FRBs. I had similar thoughts on Dark Matter, but it seams not to be the case...

Well, it depends on what you are looking at. If you are into magnetic fields, then FRB is explained quickly. When a magnetic field breaks, it creates an electric field in proportion to it.

Maybe they’re from stars that blink into existence and then instantly blink out. I could see the birth of a star that couldn’t quite hold what it takes to burn for millions or billions of years blinking out instantly and giving off a fast burst of energy. Anyway... great vid

Any chance Dr. Ed Copeland's past research on topological defects may have anything to do with FRB's Dr. Becky?

Clearly it was the battle of Endor in another galaxy.

The signature from the Death Star's Superlaser... It shouldn't have been detectable, but they didn't shield the Kyber Crystals properly... 😉

yay! :D

I'm going with one of; 1. Giant alien microwave meal 2. Giant space laser battle 3. New type of natural nuclear explosion we don't know about yet

Sounds like an EMP. They can be made by collapsing magnetic field, so I would be thinking a neutron star becoming or entering a black hole because that's what could have such a strong field and what could collapse it.

How is it known the FRBs come from afar? Can earth telescopes 'triangulate' with the different time of arrival of the signal?

Connecting of very strong magnetic field lines in an ionized gas surrounding a magnetar. Just a thought.

"What on Earth is producing them" uh.... hopefully nothing on Earth is producing them ;)

10:00 well, nothing on Earth, obviously :D Except for those damn microwaves.

I mean, FRBs are kinda neat, but something that's really baffling are astrophysical MASERs. How in the hell do you get a uniform 'beam' of microwaves from an uncontained gas cloud in the interstellar medium?

...they are probably coming from newly formed neutron stars or magnetars where their periodicity varies with the age of the object.

I don't know if you read comments on old videos, but... Could the, "Wow!" signal back in the 70's have been the first detection of a FRB?

Alien: *gingerly closes microwave... "Sorry. My bad."

Wouldn't a relativly massive body falling to the surface of a white dwarf or a neutron star at the point of collision /shortlived event/ create a radio burst

Who in their right mind opens a microwave either before it is done or without hitting cancel first??? Good God people it's radiation !!! When I was a kid my friends mom had gotten a new microwave oven, the first one I had ever seen. If you walked by when it was in use with anything metal on you sparks would come off the metal. Hated them ever since. On a side note, suddenly I find brilliance not only mentally invigorating but extraordinarily beautiful. New sub here for sure.

Could our sun be causing the frb?

iirc, the one in 2013 was associated with a NS-NS merger / hypernova, wasn't it? clear spectroscopy of gold, etc.

Somethings pushed so hard gives extra radio waves. Radio waves are radio speed.

Is it just me, or does the term "quick radio burst" describe it better?? Fast RBs sounds to me like they were "quicker" than normal RBs, which is just ... not possible. :)

👍Ok every good 👍

I wonder about how they detect this. In radio astronomy you have only a single for pixel detector and very very short integration times. There must be giant archive for all of this. It's strange to know that they are so far away and also the time of origin was very long ago. And it would be a very very low chance of this happening only in our lifetime. This must happen a lot more and could happen closer. You named 3Bn LY away/ago on one source, how do you calculate redshift due to expansion onto this?

@DrBecky

5 жыл бұрын

You can't calculate the redshift from the radio signal - the repeat observations allowed us to pinpoint location in the sky. This corresponded to that dwarf galaxy, so people got an optical spectrum to get a redshift and therefore a distance.

FRB's are from a US Naval communications satellite

Funny how you said at the end: find out what on Earth is causing these fast radio bursts. I’m sure what is not on Earth that is causing them is what you meant 🤗🤗
