I'll say here the same thing that I always say on all of my first dates:
I WANT TO SEE IT.

so, really it went supernova 21 Million light years ago...

So it blew up 168,000 years ago and we’re just now finding out about it. That star must have connections to the Clintons and Bidens.

Nope.
A Light Year is a measure of Distance. It is not a measure of Time.

My payment when down when I refinanced my whip! Yeah, I extended the term another seven years, but lower payment!
Your expectations are way, way too high.

For those saying how quick life can end this star blew up 21 million years ago the light is just now hitting Earth

Our star isn’t big enough to go supernova.

Well, only less than 1% go supernova anyway so it’s unlikely either way.
And of those 1% that do go supernova, all of them are far larger than our sun.
Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either. In order to create a supernova, a star needs about 10 times the mass of our sun

Well, that’s a pretty fricking depressing outlook.

Ban bet that it doesn’t?
It’s not even a question of if it will go supernova, it’s a foregone conclusion that it will…and do so “soon” on a cosmic time scale.

Whole bunch of dumb out there.

Downvoted the dyslexic guy for calling people dumb.

I think you missed the joke.

Err… isn’t a measure of distance over time?

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
The vastness of space is so incomprehensible. It takes me 24 hours just to get to Wyoming

No. Distance over time is speed.

umm... it's the distance light travels in 1 year... yes, it measures distance, but if something is 1 light year away, it took 1 year for that ray of light to go from source to your eyes... therefore, yes, it went supernova 21 million years ago

If a supernova occurred within 5 light years of Earth, it would wipe out life on earth instantly.
And how many stars fall into that radius?
