@@mrloop1530 My baked potato was done perfectly. However, as I was also pretending to be a magnetar, I created a colossal gravitational surge which permanently lowered the value of house prices in the neighborhood. The baked potato was still nice though 👍
Lmao the astronomers open the microwave too early created this huge invesyigation 😂 idk why that so funny sounding, but I guess it helped us learn still.
Saturday evening is the time that my friendlt neighbourhood astronomer comes out to play. When they found that the micro-wave ovens aere what they detected everyone thought that Lorimer Bursts were not FRBs even Lorimer had doubts in the back of his mind but was elated when they detected more distant bursts.
Still in shock about Arecibo. Would love a video comparing fixed dishes, steered dishes, steered arrays and the new Canadian array. Want to have a mission to build bigger and better! I love the way you tell the story. But I was left imagining the size of the magnitars that must be causing these fast pulses. They must be stupenduous. The best part of your videos is the fact that you are a scientist, and let the view draw their own conclusions. Great work, and thanks!
@@LaunchPadAstronomy yep, you just précised the history of FRB‘s down with images and humour in a way my limited brain can understand, with all of the connected theories about them as they were evolving, in a really entertaining way all in under 20 minutes.
We tend to divide things that create energy like stars, from things like rocks that don't. When in fact, since everything is made of atoms that have electrons in orbit around a nucleus, everything is therefore an energy source. So all planets emit electromagnetic forces, as do stars, as do galaxies. So we shouldn't be surprised at how energetic our universe is. I find it amazing that galaxies act just like individual atoms, and our universe acts like a gigantic solar system. The more we look the more we learn!
Mysterious Ferbys hahah.. Keep up the good work, Christian! Love the humour. This channel deserves way more views, but I suspect that it's inevitable at this point :)
And.... if someone happened to believe they saw (and video’d) about 1-2 seconds of a magnetar extinguishing in October 2020, in Australia, who would you recommend they contact about it?
Launch Pad Astronomy OK, thank you. Can they really tell how far away a magnetar is by the length of time the radiation signals continue for, or did I misunderstand that part?
Sorry I think I misread your first message. I thought you said "meteor" not "magnetar". Magnetars are too faint in the sky to be seen without a large telescope. Sorry for the confusion! As to your second question, the answer is "yes" if there's a sufficient understanding of the distribution of free electrons between us and the source. Of course, there's only estimates of that distribution, which adds uncertainty to the distance estimate, but there's certainly enough information to know it's coming from cosmological distances vs. local to our Galaxy.
I appreciate the calm and easy to understand presentation of facts :) A lot of other science-y youtube channels are difficult to follow, but you always seem to be very easy to follow and understand! Do you have a teaching degree or something?!?! lol.
@@LaunchPadAstronomy Oh you're easily more digestible than 75% of my teachers, I'm Canadian and been to University and college for 3 different 2 year programs!
That was a wonderful explanation on such a complex topic. My question is : is it possible to observe these FRBs with amateur telescopes of say size 3 to 5m dishes esp a source like SGR 1935+2154 ?
@@bcutter0.515 Thanks. Interesting. So if we could figure out how to negate our mass (our being us and the thing we sit in that does the actually negating, like a space ship) then could we too travel at the speed of light? Or close to it, without the infinite energy we'd need as I understand Einstein. Which is not at all, if I'm going to be honest.
Is this dispersion taken into account with our measurements? It seems like this should alter the outcome for equations that tell us the universe is expanding.
At optical wavelengths, dispersion is much less of an issue because the frequency of visible light is too high to be affected by free electrons, so even with this taken into account, it doesn't change our measurements of the Hubble Constant, etc.
To the individual that "disliked" this video...I've watched every video about space that I could possibly find on UA-cam and @LaunchpadAstronomy is as good as it gets! So if this doesn't make you happy then you might want to find another hobby!
Ok i have a curious question you mention free electrons . Where do I get some . Free is a great price and a price I like . Great video mate and fascinating as well . But picking on the microwave lol that was funny
Dear Christian. I've been looking through the papers of the Fast Radio Bursts mentioned in the video description table and found one an interesting, I would even say a fascinating, thing. The explanation of the different wavelengths arriving to us in a different time is not correct. I am speaking about the dispersion in a vacuum. You said the space between a Fast Radio Burst source and our detector is not entirely empty - there are lots of molecules of substance the electromagnetic waves have to travel through. As a result, these molecules are influencing the speed of the travelling electromagnetic waves and, as a result, we have a dispersion effect in a vacuum. From the Graph on "Fig. 2. A dynamic spectrum showing the frequency-dependent delay of FRB 110220", located in the article "A Population of Fast Radio Bursts at Cosmological Distances" we can clearly see that: Frequencies 1500 MHz arriving at time zero; Frequencies 1400 MHz arriving with 250 ms delay; Frequencies 1300 MHz arriving with 600 ms delay; Frequencies 1200 MHz arriving with 1000 ms delay. But, oh my, how I do love this word. But, when we open the article Dispersion (optics), we can see that the red light refracts less than the blue light, what means that the material of the prism, light travels through, slows down lower frequencies less than the higher frequencies. What in its turn means, if the molecules of substance slow down the electromagnetic waves travel through, from a Fast Radio Burst source to the detector, then we have to get lower frequencies to come first, at zero time, and the higher frequencies to come with the delay. However, we have a completely different situation here. Higher frequencies come first, and lower frequencies come with the delay. What means, in the final result, that this explanation is not correct. It's not the substance that slows down different frequencies, with a different rate. There must be something entirely different happening there. Isnt it fascinating? Regards, Sergusy.
We could, but CHIME is in many respects the best suited FRB survey instrument we could have designed :) Probably the next best option would be to build a radio dish on the far side of the Moon and just monitor the sky overhead.
What if the filament or the dark matter that holds our galaxies together is also the edge of the universe, like time inside itself, which creates gravity.

Can the collision of two drawf galaxies cause a black hole?

no it speeds up again. remember, photons are massless, it doesn't require any energy to accelerate them
