Stars have only existed for about fifty years. Duh.

How can the stars have existed for fifty years when the universe itself is only slightly under a week old?
some_guy@lemmy.sdf.org 10 months ago
I could explain, but there’s a lot of string theory involved and I only have limited time.
InternetCitizen2@lemmy.world 10 months ago
I mean there has to be a few somewhere made this year. Reminds me tangentially of something I was reading during a statistics class, that due to many possibilities and infinite numbers I should be able to open my dryer and find all clothing folded.
DarkCloud@lemmy.world 10 months ago
Youngest star is 1300 years old…
So most species are older than HOPS-315.
MonkderVierte@lemmy.zip 10 months ago
But Polaris is not proto.
marcos@lemmy.world 10 months ago
A medieval star!

Rumors to this day state it pulses to a Gregorian chant
doomsel@lemmy.world 10 months ago
If I understand correctly, it is 2billion years old, but 50million years ago it merged with another star, making it more massive and thereby more bright an visible from earth. Fun fact: Due to it beeing a yellow supergiant it will turn red in a couple of thousand years and then die quiet soon.
Saleh@feddit.org 10 months ago
“soon” and “young” are always interesting terms in Geology and Astronomy.
samus12345@sh.itjust.works 10 months ago
Tens of millions of years old? Practically brand new!
commie@lemmy.dbzer0.com 10 months ago
I love it. it feels like Polaris will be there long after this rock is barren and cold, and we can continue to navigate by it in the gay space communism
Swedneck@discuss.tchncs.de 10 months ago
fwiw it’ll at least stop being the north star in some thousand years (might be longer), which is arguably even more fucked to think about
like, people in the past had a different north star, what the fuck
dwindling7373@feddit.it 10 months ago
Apparently the star is going to fizzle out soon, but beside that, if you are not on earth it becomes irrelevant for navigation.

why would you want to dash my hopes like that?

Sharks are also older than trees, flowers, Saturn’s rings, and the Atlantic ocean.
prole@lemmy.blahaj.zone 10 months ago
Sharks are older than trees?!?
rottingleaf@lemmy.world 10 months ago
I would cut the shapes of prehistoric sharks in cardboard in my childhood. Have a pouch of those somewhere.
They were really beautiful.
owenfromcanada@lemmy.ca 10 months ago
And don’t even get me started on horseshoe crabs. Older than plants, those ones.
panda_abyss@lemmy.ca 10 months ago
In defence of plants, it takes a highly evolved form of life to be able to do nothing all day and get away with it.
jimjam5@lemmy.world 10 months ago
From Wikipedia:
Horseshoe crabs have been described as “living fossils”, having changed little since they first appeared in the Triassic.
ChickenLadyLovesLife@lemmy.world 10 months ago
Those fuckers have like nine different types of eyes. Even that tail is one big photoreceptor! Primitive, my ass - you try surviving crawling around in the mud for 400 million fucking years.
Aeao@lemmy.world 10 months ago
Back in my day you used to be able to buy twelve horseshoe crabs for a nickel… Of course that was before the war… Back then id swear at least two and a half teenth of my crew where horse shew crab but who you going to tell ? Tattling wouldn’t be invented for another 2 score years up in Kentucky you had to wait another 6!
But it’s was easier and I miss those days. If you could dodge the knowledge toads you were already 12 up on these Irish but we can’t say that anymore can we? No sir…now we got to give everything to the freckled folk and act like that’s the way it’s meant to be but it’s not. It wasn’t a thing until the battle of leaky hill… But we lost and I had to accept that to get tomatoes down at the Paul’s service at a decent price. Don’t even get me started about the tomatoes. You never damn believe it.
Sorry I’m going to be a grandfather soon so I’m practicing

thinking about things too much makes me feel ill, i try not to do it very often
Aeao@lemmy.world 10 months ago
Explain what you mean in 6 paragraphs please
Aeao@lemmy.world 10 months ago
I got to ask all the Internet tho… Which is better?!
The concept of north?
Or sharks?
Saleh@feddit.org 10 months ago
Dont need the north star for the concept of north.
Aeao@lemmy.world 10 months ago
And you don’t need alligators to make a swamp. Not relevant to the question I asked.
rottingleaf@lemmy.world 10 months ago
Sharks are cooler.
Klear@lemmy.world 10 months ago
North is very cold tho.
ArbitraryValue@sh.itjust.works 10 months ago
North star? More like noob star.
logicbomb@lemmy.world 10 months ago
Also from Wikipedia:
Although appearing to the naked eye as a single point of light, Polaris is a triple star system, composed of the primary, a yellow supergiant designated Polaris Aa, in orbit with a smaller companion, Polaris Ab; the pair is in a wider orbit with Polaris B. The outer pair AB were discovered in August 1779 by William Herschel, where the ‘A’ refers to what is now known to be the Aa/Ab pair.
I learned something new today. And if I’m reading the details section correctly, while the outer pair of stars are actually older than sharks, it’s the bright star that you can actually see that’s younger than sharks.
Skullgrid@lemmy.world 10 months ago
And if I’m reading the details section correctly, while the outer pair of stars are actually older than sharks, it’s the bright star that you can actually see that’s younger than sharks.
This makes even less sense, how is the heavier thing in the middle younger than the things that orbit it?
ryedaft@sh.itjust.works 10 months ago
The bigger the star, the brighter it burns
Also it dies sooner. So any given big star is more likely to be young
Aeao@lemmy.world 10 months ago
I can explain that but I have to use the only thing available to illustrate.
So imagine my left testicle here formed before this penis in the middle… And yes it is technically a penis despite the small size, and this testicle-
dwindling7373@feddit.it 10 months ago
I may be wrong but a mass of inhert hydrogen has the same mass of a radiating one, so they could have been orbiting a mass of gas a long time before the “newer” one ignited.
ch00f@lemmy.world 10 months ago
45-67Million Years according to Wikipedia.
Sharks are hundreds of millions.

Fuckin’ Sirius. So close and yet so far.
ChickenLadyLovesLife@lemmy.world 10 months ago
Not directly relevant, but I think Keanu Reaves named his band “Dog Star” because he was “Sirius” about his music career.
frenchfryenjoyer@lemmings.world 10 months ago
all these new stars nowadays, it’s hard for old me to keep track lol
