Betelgeuse Going Kaboom Very, Very Soon

As with Uranus, there has been a subtle change with the way Betelgeuse is pronounced, when i was younger it was always pronounced as Beetlejuice but seems like to distance it from the film of the same name, astronomy types want to pronounce it as Betelgeist but that may be irrelevant because it may soon become known as a massive black hole 650 light years away because Betelgeuse is predicted to go supernova very, very soon.
A supernova is the extremely bright, super-powerful explosion of a star. In short gravity wants to crush it inwards but the outward pushing burning fuel inside the star keeps it from collapsing but when the fuel runs out...BANG.
It explodes and sheds all it's hots gas and what's left is the dense, gravity crushed core and the last Supernova seen from Earth was in 1604 and was described as bright as the moon during the day which sounds very cool indeed or at least very cool as long as the thing happens further than 100 light years, any closer than that and our ringside seat would not end with a ringside, a seat or any of us to say how lovely it looked.
The first step of a supernova is the Star has to dim as the gravity starts to win the battle against the outward pressure of the fuel and Betelgeuse has become noticeably dimmer since 2019 and as the light from the star takes 650 years to reach us, it meant the destructive process started in 1396 when England and France were only at half-time in their 100 year war.
The Hubble Space Telescope has also captured images of Betelgeuse starting to shed its outer layers and just getting ready to go the full kaboom and make a mess of the shoulder of Orion so get the deckchair, grab the popcorn and something wet...and then put it back again because to our normal people very, very soon means something very different than when an Astrophysicist says it because it will go supernova..sometime within the next 100,000 years, give or take.
It could be tomorrow, it could be the year 102,023 but i wouldn't hold my breath but i do find myself looking towards Orion in the Winter months just to make sure he still has his shoulder.
