- In October 2022, astronomers witnessed the most powerful gamma-ray burst ever recorded, dubbed the B.O.A.T (Brightest of All Time). This extraordinary explosion from 2 billion light-years away unleashed more energy in seconds than our sun will emit in its entire lifetime. Join us as we explore the science behind this cosmic event, the mystery of its missing signatures, and the insights it offers into dark matter and the formation of heavy elements like gold. Dive into the fascinating world of gamma-ray bursts and discover what this monumental explosion tells us about the universe's most extreme phenomena.

Not 2.4 billion miles away, but 2.4 BILLION LIGHT YEARS away. What's that...like several hundred galaxies away? Across the universe?? It's a LOT.
Yes, 2.4 billion light-years is an incredibly vast distance, far beyond what we can easily imagine. To put it in perspective, 1 light-year is about 9.46 trillion kilometers, so 2.4 billion light-years is truly an astronomical number. It stretches across not just hundreds of galaxies, but likely a significant portion of the observable universe. The fact that this event happened so far away and still had an impact on Earth is truly mind blowing
The Milky Way has a diameter of about 100 thousand light years. 2.4 billion light years is not a few hundred, but about 24,000 galaxies the size of the Milky Way. That's insane.
@chaszaszman_9868 There are 2.5 million light years between The Milky Way and Andromeda. Using this figure, because even though the diameter of a galaxy is vast, the distance between galaxies is far greater, you would come across 960 galaxies if you travelled 2.4 billion light years in any one direction.
So basically incomprehensible
Normal people really can’t comprehend that distance
The gamma-ray burst (GRB) on October 9, 2022, called GRB 2219A, was the brightest ever observed, with its energy levels 10 times higher than any previously recorded GRBs. It lasted for 10 minutes, with an afterglow visible for over 10 hours, making it an unprecedented event in terms of both intensity and duration.
Why are you repeating the narrator 🤣🤤🤤🤤
@@jonscholes8721my exact thought
Because it's worth repeating!@@jonscholes8721
"occurs only once every 10 thousand years"
Now how in the hellcould you possibly know that?
I been counting the years, and it's been happening without fail for the past 40 thousand years of observing it n so it's safe to say that it occurs every 10 thousand years.
You can look for patterns. For example studying layers of the Earth's crust tells you lots of things like how CO2 levels went up and down cyclically or when the earths magnetic poles switched. They can come look for other things to know about other past events.
Jesus did you really just fucking ask this?
@@davemccombsIt's the Internet dave.. people aren't very bright and if they don't understand something they jump to "That's wrong," rather than actually looking into it. Brain rot.
Beautiful presentation.
You and your team make great content.
Thank you!
It's literally low-effort, AI-generated and narrated content. That's how low your standards are.
The universe is a mere appearance, and reality is hidden.
A little vague but I get your meaning. And I agree.
The little bang
I can’t wait for her to join the new wave of WNBA stars!
THANK YOU !!! Such a clearly written essay that does not condesend or lose the audience with austentsious vocabulary. It's a wonderful presentation of fascinating information. I have subscribed
BOAT means "The brightest gamma-ray burst of all time". Have you been smoking again?
Real person or AI voice? Being Texan I appreciate the accent.
You ain't seen nothin' yet, wait until we witness a super Black Hole explosion. Astrophysics doesn't even have a word for it.
😂 they were shocked 😂
At one point it sounds like he says "our sadmosphere" ):
Good Night guys
Repetition can be boring....Repetition can be boring...Repetition can be boring....Repetition can be boring....Repetition can be boring !!!!!
Let me guess now the human races new goal is to create a gamma ray bomb 😂
It Elons Tes Star 💫 running amuck
Discovered on my b-day!! Lol
Where do werdos come from?
So how can that be in our galaxy if it was 2.4 billion light years away? Our galaxy stretches 100K light years across. This would have to be from another far far away galaxy. And from that distance shouldn’t that already happened in the past?
Space is Past
T
Get to the point
2.4 billion light years away. good god..
garbage
Yep, your opinion is:-)
Do better.
NOT THIS “SOUTHERNER” AGAIN! THIS ACCENT IS AN ANTI-INTELLECTUAL, HILLBILLY VOICE THAT IS. VERY DISTRACTING IN A SCIENTIFIC TOPIC!
I resemble that remark! Ozarks native.
must have slept when it happened, didnt notice a thing
