They usually do that to items that are not in stock yet or special deals that have ended. Told me that it allows them to have the item in their system and ready for when it shows up, but keeps inventory from going negative before they get it. Their entire system is way out of date. Supposedly they’ve been working on a new one for awhile.
I love reading things about space and astronomy... until I don't. I always makes my head go 'on tilt' and then it makes me frustrated. I just read this about Betelgeuse. Where we see it now at a distance of 640 light-years seems very far away, and it is, but then I remind myself that the Milky Way is 100,000 light-years across.
If this is accurate, Betelgeuse exploded over 600 million years ago -- the show is just now nearing Earth... It's taken that long for the light to get here!
Something incredible is brewing in the constellation Orion, and the entire universe might be about to put on the most dramatic show ever. The star Betelgeuse, a massive red supergiant located around 640 light-years away, is reaching the final stages of its life.
This star is no ordinary space object. It’s 10 to 20 times more massive than the Sun, and it’s been burning through its nuclear fuel at an intense rate. In recent years, especially during the 2019–2020 dimming events, Betelgeuse has shown strange and unpredictable behaviour. These flickers and dips in brightness have scientists on edge, wondering if the long-expected supernova is finally near.
If Betelgeuse explodes, it will release an unimaginable amount of energy, briefly shining brighter than entire galaxies. And here’s the exciting part. The supernova explosion will be visible from Earth, even during the daylight hours, and could last for weeks or even months as a blazing point of light in the sky.
There is no danger to Earth since Betelgeuse is far enough away, but the event will be a once-in-a-lifetime celestial spectacle. The explosion will also enrich space with heavier elements, spreading the building blocks of new stars and planets into the cosmos.
Astronomers around the world are constantly watching Betelgeuse, checking for brightness changes and other signs that might hint at the final collapse. Whether it happens in our lifetime or centuries from now, one thing is certain. When Betelgeuse goes supernova, it will be the most spectacular event ever recorded by humanity in the night sky.
Interesting, but if Betelgeuse is 640 light years away, then it takes light from it 640 years to reach Earth, I think. I'm not sure where the 600 million is coming from?
But a light year is still one Earth year. The distance light travels in a year is about 5.866 trillion miles.
If something happens in space 640 light years away, it takes 640 years to be observable on Earth.

No, an earth year is a measurement of time. A light year is a measurement of distance.
The speed at which light travels is not the same as the amount of time it takes for something to become visible over such a distance.

Yes, but the definition of Light Year is the distance light travels in a vacuum in one Earth year based on the Julian calendar of 365.25 days.
I disagree with your second sentence completely.

Measuring in light-years also allows astronomers to determine how far back in time they are viewing. Because light takes time to travel to our eyes, everything we view in the night sky has already happened. In other words, when you observe something 1 light-year away, you see it as it appeared exactly one year ago. We see the Andromeda galaxy as it appeared 2.5 million years ago. The most distant object we can see, the cosmic microwave background, is also our oldest view of the universe, occurring just after the Big Bang some 13.8 billion years ago_.

I don't have problems, just more work to do.
Did you see it?

It’s pretty cool that they use that number too.
Ah, I just got it from Rusty's comment. Jenny, Jenny, you're the girl for me!

How come it doesn't just implode into a black hole? Seems like it would save the cosmos a lot of trouble.

They’re different measurements. A light year is the distance light travels in a year.

Hell, it may have already happened and we just haven't seen it yet.

If it happened today, our great-great-great -great grandchildren will be dust before the earth sees it.

That's the way everything works when viewing distant things in space.
Ok
Light travels at 670,616,629 mph. So by your reasoning if you shine a flashlight in the dark and I see it…you did it 670,616,629 years ago.
