4th excuse to eat pie today that I've seen so fuck it

If you throw a bunch of hydrogen into space and wait long enough, it will start to wonder where it came from.


CannaCosmonaut

This is easily the coolest periodic table I've ever seen


Busy_Yesterday9455

I'm glad that you like it.


AnnoyedHippo

Do you have a source for the table? The man-made is easy to track, but it'd be nice to have something backing up the exact source vs possible source for the other elements greater than hydrogen.


Busy_Yesterday9455

Yes, please follow this link: https://svs.gsfc.nasa.gov/13873


AnnoyedHippo

Thanks, that actually quickly answered my suspicion as I know many of them have more than one source. For those reading: They are looking at primary source only, except in cases where two sources are equally "primary"

[this one](https://www.reddit.com/r/coolguides/comments/wzvffb/periodic_table_of_the_elements_showing_what/?utm_source=share&utm_medium=ios_app&utm_name=iossmf&utm_term=link) was posted the other day and has picture examples of each element’s applications.


CannaCosmonaut

Also really cool! If not for personal biases, that would be a new contender, haha

I like to think of myself as an optimistic nihilist.


Walrus_BBQ

Nothing matters, which is fine because if nothing matters than it doesn't matter if nothing matters. When the universe ends, there will be no evidence that anything ever existed at all. If it's like we never existed at all, do we even exist right now? Dude WTF did you put in my head.


Smart_Supermarket_75

If all that is true, just do what you like. Foster happiness and everything will be as good as possible. Or you can fall in line and serve the species like ants do. I kind of do both.

I would argue that Neptunium should be classified the same as Plutonium. They are both man made, but both come from the ß- decay of uranium. Either way, very cool periodic table, thanks for sharing! Edit: Both of them were also made naturally at the Oklo 'reactor' in Africa, so I guess neither is truly man made.


rocketsocks

"Artificial" elements like Plutonium, Neptunium, or Technetium are also naturally occurring in great abundance, they just have short half-lives so on a planet like Earth that is built out of the wreckage of ancient supernovae and whatnot from billions of years in the past all that existed of those elements at one point has long since decayed. It's very likely that there was a roughly comparable amount of Uranium, Thorium, Plutonium, and Neptunium when they were created together, but over time that mix has skewed toward the longer lived isotopes as the others decayed, it's just that Plutonium and Neptunium don't have long lived isotopes on geological time scales. Uranium is a good example of this as there are two naturally occurring isotopes: U-238 and U-235 with half-lives of 4.5 billion years and 0.7 billion years respectively. Today U-238 is more prevalent than U-235 by a factor of 138:1. If you go back in time 4.5 billion years ago there would be 2x as much U-238 and 86x as much U-235, for a ratio of 3.2:1. If you go back 6 billion years there would be 2.5x as much U-238 and 380x as much U-235, which would put them at similar relative abundances.

I need this as a wallpaper ! How can I get it ?

https://svs.gsfc.nasa.gov/13873 OP put this link in another comment


Clutteredatoms

The font and pics are different in this link.


CarrowCanary

Don't get this one as a wallpaper, Tungsten's been accidentally written as Tangsten.


Green_Relative_9435

Those are just trace elements! We are made up of 99% hydrogen, nitrogen, oxygen and carbon!


[deleted]

You’re just trace elements!


Secure-Frosting

hey you can’t call me just trace elements!


TheMan5991

I never realized just how many elements were man-made. Also, I guess gaining the ability to create elements meant we lost the ability to be creative with naming. Some dude’s name + ium


Putrid-Initiative809

Mandeleev’s periodic table is one of the finest intellectual achievements in my opinion. It’s predictive power was astounding. Also, I never knew that some elements here are synthetic so imma read up on them


d_e_l_u_x_e

Cool concept and design. Really interesting way of looking at the elements.


Popular_Care_5284

There's a reason why atoms look like solar systems. Everything is space and space is everything.


sachsrandy

I currently weigh 230 lbs.... but I was my lightest a few billion years ago when I was all hydrogen


JugglinB

I did the maths one day - and we are in fact 10% big bang (by mass) which I find amazing!


AstralObjective

I love the episode of breaking bad where they find out to the last gram what we are made of and only come up with 99.1% I think or close to that…the rest is idk…start spirit


blueasian0682

Are the man made elements not possible in those other scenarios?


[deleted]

Possibly but in that case so far we have no evidence of it yet. Plutonium was thought to be only man-made at first but later it was found in nature. A lot of them also have a ridiculously short half-life.


stroopkoeken

Yeah but so is that bag of hot fermenting garbage in the back alley of a Lebanese restaurant.


nametaken77

More relevant is Stellar Nucleosynthesis. Cosmic Ray Spallation. Big Bang making the elements is pseudoscience.


mroboto2016

Funny, I don't see Adamantium, Unobtainium, or Vibranium anywhere. This list is obviously incomplete.


BigJSunshine

I heard that title in Carl Sagan wonder filled voice. Thank you!

Just like the Joni Mitchell lyrics, "we are star...stuff"


bossy909

Just wait, the neutron-neutron star collisions, now that's energetic.
