Our star isn’t big enough to go supernova.

If a supernova explosion were to occur within about 25 light-years of Earth, our planet would probably lose its atmosphere, and all life would perish. However, astronomers haven't found any dangerous supernova candidates in our cosmic backyard, so there's no reason to worry.

That’s 25.9 trillion miles. Or 6 trillion less than our national debt.
So if I traveled one mile for every dollar the US government is in debt, I would have passed up this this place.

Well, only less than 1% go supernova anyway so it’s unlikely either way.

I don’t think the human race makes it to the year 2100. Some type of natural or cosmic cataclysm is going to wipe us off the map eventually.

I would like to see a Supernova star so close to us that we can see it at noon on a sunny day.

don’t be a putz.
“the light from the supernova reached earth last week”
that better?

better keep a close eye on Proxima Centauri then

So, 1 week and 21 years ago?

You may get your wish. Astronomers have been reporting Betelgeuse is showing some unusual activity and is a good candidate to go supernova.

I recalibrated my algorithms and data endpoints and can confirm it is/was observed in a galaxy 21 million lightyears away.

Wouldn’t this be 21 million years ago?
Light travels at 168000 miles per SECOND A light year is how far light travel in a year. The star that went supernova is 21 MILLION light years away.
To kinda put this in perspective, the light from our sun takes about 9 minutes just to reach Earth.
Space is vast.

Well…I mean, that’s making a lot of assumptions, but maybe.

Just don’t say it 3 times back to back.

The one statistic that put the speed of light into perspective for me was that light can travel around the earth 7 times in one second. Just say 1 Mississippi out loud and think about something going around the entire planet 7x compared to how long it takes us to travel just short distances.
Looking at the OP image and thinking about a star with a size we can't comprehend, that has an age we can't comprehend, at a distance we can't comprehend, exploding with a violence we can't comprehend, and thinking we really matter in this universe seems silly

Downvoted the dyslexic guy for calling people dumb.
