It's official - Betelgeuse isn't about to explode

Scientists have finally determined what made the giant star appear as though it was getting ready to blow.
The red supergiant, which can be found in the constellation Orion, is certainly no stranger to changes in intensity having been going through periods of dimming and brightening for thousands of years.

More recently however, a particularly notable period of low intensity had led scientists to speculate that it may be about to go supernova - producing a monstrous explosion of stellar proportions.

Such an event, when it does happen, could make Betelgeuse (which is 700 light years away) appear so bright in the sky that it would be like a second sun - albeit only for a few weeks.
Now however, Betelgeuse seems to have returned to normal and scientists have determined exactly what happened - the star had belched out a large cloud of dust, temporarily reducing its brightness.

This also means that it won't be going supernova anytime soon.

"We see this all the time in red supergiants, and it's a normal part of their life cycle," said University of Washington astronomer Emily Levesque.

"Red supergiants will occasionally shed material from their surfaces, which will condense around the star as dust. As it cools and dissipates, the dust grains will absorb some of the light heading toward us and block our view."

You haven't provided any facts, you have spouted off some numbers and are claiming them to be true. Personality wise you are also quite a frosty one arent you? You have no scientific links backing up you argument. So lets begin. Firstly Earth is not 8 minutes from the Sun but 8 minutes and 20 seconds. Thats a significant difference. Now lets look at scientific articles for how far away Betelgeuse is. I presume you must have taken 700 light years from Wiki? If so please scroll down and read the part where it tells you about how its distance was calculated. It explains several approaches were us... [More]

So,  the scientists were wrong?

Hell, Betelgeuse could have went supernova years ago and none of us would be none the wiser.

Is there a relevant point to this post ?

So called Finite Fossil fuels, according to “Scientists” .  The Earth is a livings organism, petroleum is its blood.

So the answer to my question is no then.
Comment icon #21 Posted by Festina 2 years ago
  I updated my post.

So the answer is still a no then. Atleast I don't see any connection at all to Betegeuse in your woo.

They were wrong about Betelgeuse and they have wrong about other things as well. The Connection,  It’s called conversation, and it has movement.   Goodnight.
