Betelgeuse and dimming

Betelgeuse stands a very good chance of gradually brightening again, and going about its business for a very long time to come. If it doesn't, we don't expect it to simple fade away, though. 

People like to consider unusual possibilities, and the exceptional. A supernova is one of those possibilities. 

What are the other possibilities?

I am sorry that I am asking many questions but one comment had mentioned that it can just dim into a supernova. And other seem to say if it keeps dimming it’s unusual so not sure which is right answer?

also don’t expect it to simply fade away ? What can it do instead

Media sensationalism.

Compared to the huge distances between stars.

when someone suggests the speed of light is so god-awful slow, i feel a need to ask: "compared to what"?

therefore i've no idea how to reply to your quote

Light is super slow. The star right next to us, the one we call the sun, it's light takes 8 minutes and 20 seconds to reach us. That's 500 seconds! And it's right next to us!

Light is super slow compared to what?? what are you on about?

The observable universe is 93 billion light years across. That's the time it would take light to go from one end to the other. 93.000.000.000 years. That's almost 7 times longer than the age of the universe itself.

Hmm... Compared to the speed of imagination and thought?? Are there any other things to compare it to? Light is the fastest thing in nature we know.

Yes, Betelgeuse will dim first before going supernova. Supernovas are very rare, so the sort of dimming that precedes one is also very unusual.  A star of Betelgeuse' mass will contract under gravity, once it has used up its available hydrogen fuel, and then rebound explosively as a supernova

True, a supernova at Betelgeuse right now won't be seen for centuries. If we see it supernova soon, this will actually have occurred about the year 1380.

Wow. Watching a show about London's underground and they were just talking about the Black Death in 1348. Kind of gives you some focus on how long ago the light we see now left Betelgeuse.

So it will eventually brighten again and not just Dim until it’s gone then 

 

so what’s this very usual talk then?

You need to realize that this star, "Betelgeuse" is over 642 light years away! At that distance, it could have imploded and turned into a Black Hole years ago.
I feel you're reading more into it than what is really known!

Here is the newest update, still dimming 

So if I understand correctly and you can correct me if I am wrong, the dimming is because the star is burning itself out. That causes dimming which eventually when it is fully burnt out or dimming it can go supernova. 
 

if it keeps dimming sign of possible supernova if it stops dimming and starts to brighten then not sign of supernova. 
 

i hope I finally understand

It's not unusual for the star to be fading, that's what happens.

It's unusual because it's a rare thing for for us to observe. 

Don't worry, you're safe.

Would Betelguese supernova be the most power ever would the size of it? 
 

Would it be the biggest on detected history or has there been more powerful?

i havé also read the dimming is slowing  down which means that it may not be ready to go yet?

do you all think it will happen in our lifetime?

Light is slow compared to need.

It would mean Trump wouldn't need the sun bed any more.
