    I love how UA-cam 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.

    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.

    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.

    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.

    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.

    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.

    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...

    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

    USAF x37b opening "dark matter" walking through and not knowing where it is. so using echo location to determine where it is. Now that that is solved, off I go into the wild blue yonder. p.s microwave ovens were a byproduct of the original radar dishes. the x37b has heat absorbing "fiber" glass which turns the heat and radiation into electricity and is channeled to "diamond battery" banks. This allows the collection of electricity in excess of that produced by a nuclear reactor. Then by sending energy really fast through a radar dish and funneling the burst though layered gas tubes you get really fast radio bursts. By knowing the speed of the burst through the different gas tubes allows the receiving dish to know the craft's exact distance from at least 6 collector dishes.

    If these radio bursts are coming from 3 billion light years away, shouldn't they be "red shifted," in which case they're even more energetic than they appear?
