From a certain point of view, due to the fact that information cannot travel faster than the speed of light, you could argue that in our part of the galaxy the explosion truly hadn’t happened yet until the light got to us
@Ahbar Ahad what they mean is that information cannot travel faster than light, so until we saw it, it hadnt technically happened to us, as everything wouldve been the exact same until the light reached us, including gravity and any effect it mightve had etc.
@@urimc Why weep over the simple clarity conceptualized in the Physical Principle of Least Action, or by the Laws of Motion, Thermodynamics and Relativity? Because logic can prove a "Creator God" never existed for the simple reason that it is not necessary for it to exist and all things can be explained and understood without it?
@@cordongrouch9323 I dont know about you... but i have the feeling @Darth Uri meant it as a joke. Not sure if you meant that reply as a joke too or not but yeah.
Once in a lifetime? I would say Once in millenia or so. 2years of great night light in the sky... I am sure some believed that their God was doing something, or the end of the world.
@The super dogs OH, OK. If that is happening all the time, why are we talking about 1054 not another. This one was spectacular and it lasted 2 years. Imagine 2 years of bright night sky. How many did we see that in the last 100yrs?
What's also beautiful is the fact that 10,000 years ago people were not understanding what a bright light was but nowadays we have things that are thousands and thousands and thousands of miles away
Hate to burst your bubble, but it's extraordinarily unlikely anyone alive today will see Betelgeuse go supernova. Betelgeuse is ~600 light years away. In order for anyone alive today to see it explode, it would had to have already gone supernova somewhere around the time of Henry V. It's possible, but even with its perturbations, if they are the start of a supernova, but still unlikely. Stars lifecycles are counted in thousands and millions of years increments. I'd love to see Betelgeuse go supernova before I shuffle off this mortal coil too. I just know it's less likely than me being a sole powerball winner.
I believe Betelgeuse is at a point where it may go supernova at any moment. But with how things go in the universe, it's very possible that it may not happen in our life time or even our great-grandchildren's lifetime. However it COULD, and that is the best we can hope for at this point.
Its times like these, I wish my passion for math equaled my passion 4 space 😢, your awsome dude your vids make me remember day to day how small we really r and how we should humble ourselves thank u 💯
If your wondering why it took so long to for the star to stop shine is because it's was millions of light years away so when it exploded it would be only 2 possibilities the material and gas would stay there for a short time but it would most likely be this the star was millions of light years away so when it exploded the light traveled for years to reach earth so when it did reach the light kept going it's like water still falling even if you closed the valve but it's light Example: the light of the sun takes 8:20 to reach earth so if the sun suddenly disappeared it would take 8:20 for us to realize it's gone because light is still traveling it's the same for the star
It's so sad that we will experience nothing compared to the things that are there to be experienced Edit: to everyone who replied me thanks a lot for your kind hearted comment It really helps me to understand the importance of being born in a era that doesn't have world ending ai, natural disaster or any other apocalypse. An era in which i can live and die peacefully cause i know that there are billions of galaxies in the cosmos with trillions of stars each having a planet inside its habitable zone with the possibility of life existing on them which is far greater than being born in stone age or a era of war in the past without this technology and modern science knowledge. Again thank you everyone for opening my eye :) (Not to mention that the universe is probably infinite so there could be a different me somewhere out there experiencing the things that I wanted to)
At least we are born now. In an age of medicine, discovery, understanding, science and technology. Better than being born in the past with little to no understanding of the universe, cold, starvation and strict rules and laws about modesty. At least we are born now before the water shortages, droughts, mass deforestation to the point of no return, infertility in humans due to the micro plastics we consume, be glad we won’t burn when the sun expands before imploding. We are in a time of safety after the age of technology was invented but before our apocalyptic demise.
the thing is, everyone is saying we will never witness something as amazing as this from our universe, but literally anything could happen at any moment! the beauty of it is we would never be able to see it coming
@@Idkidkidk494 what they meant was we evolved scientifically. These people didn’t know what it was and thought it was religious or the end of the world. People now know what it is.
The nebula is around 6500 light years away so it isn't really old compared to a lot of things we see out there. In real time, the star exploded 2k years after Gobleki Tepe was built
I saw something like that a few years ago. Asked around, nobody seemed to know anything about but. It didn't last long, didn't move, and was slightly brighter than everything in the night sky. Then pow, it startled me. Like a ridiculous light turned on. Then at a point, it slowly dimmed then stayed fir awhile like it started, then gone.
@@robertm1672 you are saying that you watched a star explode. Right ? But the thing is there are no (visible to the naked eye) star explosions for almost a 1000 years
@Dolly Nawaka I am saying I saw something that resembled. Your adding I'm the rest. And your intellectually deceitful, as there's plenty of documented sightings of cosmic explosions. Fyi, I was at Lowell observatory. Feel stupid now.
I’m sure there’s an easy explanation, but if we can still see with a telescope then why is it not still visible on earth? Like why did it go dim? I wanna assume it’s because it spread out wide enough to no longer be bright enough, but at the rate of space 1000 years just doesn’t seem long, and it didn’t even take that long to go dim. Again likely a very simple answer that’s going straight over my head. I’m curious😂 I should note it’s possibly a visible spec if you were in an area with no light pollution, im aware that that in the past 1000 years has definitely made a difference
it's amazing how we improve our technology so fast. in 1000 years, we already moved from a simple civilization to a complicated technology civilization. In the next 100 - 200 years, we could already have a space colony in a space dock with asteroid mining as livelihood.
My head when he said supernova Su -su su supernova nova can't stop hyperstellar 원초 그걸 찾아 Bring the light of a dying star 불러낸 내 우주를 봐봐, supernova So this is a kpop song
Idk if anyone else has commented this but just some friendly feedback the interesting thing about supernovas is that they actually implode rather than explode
Crazy thing is the actual even may have happened millions of years ago and they witnessed it after such a long time because of the time it would take light to travel the distance.
