The Star Explosion So Powerful, It Compressed Our Atmosphere from 2 Billion Light Years Away

[@dainbramage9508]

Considering how this happened during a time when we actually had the tech to see it makes me wonder if these events are relatively common on an astronomical timeline

[@8rlx0]

1 in 10000 seems pretty common in astronomical timeline

[@yaldabaoth2]

With a sample size of 1, it's impossible to tell.

[@thorr18BEM]

Very narrow emissions though so shouldn't be perfectly aimed at us most of the time.

[@idrbn3]

It happened 2,000,000,000 years ago. We just happened to live in a time where we had the tech to see it.if we had never evolved to do that then we just wouldn't know about it yet it still happened.I believe it's highly likely that we will never figure out the how,why,where and when was because fundamentally everything is quantum ( as far as our science allows us to describe it) .....unless our science and tech can "rewind" EVERY event in the ENTIRE universe from now back to then🫡

Not a gamma ray burst, but around 2007, I was up at 3AM with my dad to watch a Persied meteor shower. We saw several nice meteors every minute with orange/green whispy ion trails. Then we saw an extremely bright bolide meteor streak across the sky and flash several times with several colors. Blue red and white and the green/orang ion trail glowed for maybe 2-3 minutes. Probably the coolest thing I've ever seen. I'll never forget it.

[@mirthenary]

On Sept 17, 2021, I was on my way to Elkins, WV for work, and saw a meteor in the middle of the day! There were a couple of bright orange flashes, and it was gone, but it left two puffs of smoke behind! By the time I pulled over to take a picture, it was starting to blow away. But I still have the pic of it. Pretty amazing that I caught an actual meteor in the middle of the day

[@thanos8914]

[@CC-ns2ds]

I got drunk with friends and climbed on my school roof one time at night to watch a meteor shower and an absolutely huge (huge relative to the others) one plunged, what appeared to be, straight down and glowed bright blue-white and left what I could only describe as a ‘scar’ in the night sky, I’ll never forget that.

[@paulc5525]

In 1989 i was rafting in Nepal. One night I couldn't sleep and was just gazing at the sky, when i saw a flash of light. It expanded and receded in about 3 or 4 seconds, like something exploding. Everyone else was asleep so couldn't compare what I saw. Maybe it was meteorite, but it didn't move.

[@bill9540]

[@VaraLaFey]

Could've been a meteorite coming straight at you. Neil deGrasse Tyson has a similar story from during one of the meteor showers.

[@edmoran869]

When a meteorite is coming straight at you, it doesn't appear to move, because the ability to detect movement is proportional to its angular momentum. Just as if it was moving directly away from you. But if it goes in any other direction in even seconds of arc, movement is detected.

I attended a public seminar given at my research institute by the man who theorized and named the Axions, and won a Nobel prize for it his work on time crystals, Frank Wilczek. So this comes directly from the horse's mouth, even if I might be botchering some of the details from my recollection. I am also telling this because it was said in a public forum, even if it feels like a cool secret to keep. He said that as a child/teenager/younger self, there was this brand of detergent called Axion, that sounded like a particle and he said that in the future he would use that name for something. Then the axions were discovered, and there were even some competing names (I cannot recall at the moment, but they were not that great), he said "You can thank me for a much better name". He said that he was very lucky that there were some connection between these particles and some axis, so that he had an excuse to call them Axions. So, yes, the particle is not named after axis, as many scientist think, but after the detergent. The axis thing was just the excuse given to the journal publisher and referees.

[@anirudhnair558]

Just curious, what was the research institute? and if the seminar was recorded?

Alex, have you ever thought of nothing? Like before the big bang nothing. I've been thinking about it a lot recently. Maybe nothing is impossible and maybe thats why we have space time foam and spooky quantum physics, particles popping into existance. If nothing is impossible, for us the universe has an age as we experience time, but since there was no time before, there is no real beginning and the universe could might as well be infinite, there will always and forever be something. Might be worth a video on its own. Love your episodes. Watching both on YT and listening as a playlist when I go to sleep. Thanks for your hard work!

Both came into being at the same time, and the box was already full of air at that point.

when calculating the immense energy of a gamma ray burst is the fact that the energy is concentrated into a thin (do we know how thin?) stream used to come up with the energy output? the brightness of the sun is at a disadvantage when compared to a narrow beam? or do they just compare the apparent brightness of any objects i was wondering what the odds were of being directly in the line of fire, but i guess if we knew the angle of spread of a grb we'd just have to take a fraction of the entire sphere... 🙂unless the burst itself is so powerful it creates its own EM frields that spread the beam out more

[@yousaidthusly461]

You can visually see these large GRBs in the night if you’re lucky; but they’re ultra-fast flashes that look like thunder flashes. The difference is the intensity is incredible, like a flash photo being taken nearby. It also has the uncanny visual effect of depth of field; being from outside our solar system, the entire black background of the universe momentarily flashes; objects in the way shadow the glow, and faint spots dot the sky. These are actual objects, but each so tiny and far away it’s like static on a screen, except the white flash encompasses more of the visual field and happens so quickly that the dots are barely noticeable. But if it lasts long enough, the entire Oort Cloud and Kuiper Belt can potentially be visible. Lastly, the speed of light reflected off the Oort Cloud creates a ghost “ripple” effect where the light “wake” is seen, the effect of light bouncing off the objects in the cloud reaching us after the initial GRB! But if the GRB is too fast or has mostly non-visual EM emissions, these effects are not visual and must be detected using instruments

[@Pados_music]

Are you referring to gama ray bursts? I don't thing that are visible.

[@yousaidthusly461]

@@Pados_music In ultra-high spectra no. It’s when the light is reflected off of a surface where the energy can drop down to visible spectra. And most Gamma Ray bursts do not since energies from them are mostly in gamma, x-ray, and infrared spectra, which either pass through or get absorbed by most material. But one so powerful and long lasting it not only blasted against and compressed our atmosphere (!!!!!!) from the sheer energy released by the nova and its proximity, there would definitely be a brief visible artifact of the GRB due to it interacting with particles on the way to the surface of the Earth, and there is a better likelihood that a GRB that close would have a higher chance of lower EM spectrum reaching our solar system unobstructed. I have to emphasize how incredibly rare it is to actually “see” a GRB since there’s no way to know it is one unless you verified its origin; if the spectra emitted react off of surfaces; and if your brain happens to catch the brief moment, since it’s frequent to occur faster than the human mind can process images.
