No wonder I’m so fucking tired

No wonder.

  • Water: 2 hydrogens per 1 oxygen, 66%!
  • Carbohydrates: same story
  • Fats: a LOT of hydrogen
  • Proteins: yep, lots of hydrogen!
  • Vitamins: same

Most organic molecules feature a lot of hydrogen that essentially serves as a placeholder for all the free bonds of carbon (and there is plenty!), oxygen, and nitrogen. Hydrogen is essentially the default thing to connect to about any organic molecule. And yes, it is primarily taken from water in the grand scheme of things.

To expand on that, hydrogen is just lone protons. Some of those protons pick up an electron, but if it’s a proton, it’s hydrogen. And considering that nuclear fusion is hard^[citation needed]^, it makes sense that one of the most common things to attach to other atoms would just be the smallest, most abundant, and most simple kind of atom out there.

JasonDJ ,

Well there’s usually an electron orbiting it…and sometimes it’s even stuck to a neutron.

You had me wondering if “hydrogen” was just the name we’ve given a rogue proton.

bionicjoey ,

An H+ ion is a rogue proton. I’ve heard a physicist say before that she always would forget this fact.

Hydrogen is a colorless, odorless gas that, given enough time, starts to wonder where it came from.

Lovecraft Howard Philip called the author a clown. I don’t know if that’s an insult or a compliment, given the time period that would have had to be in. Clowns were cool at some point, right?

Aatube OP ,

That's an intriguing way to look at it. I can't find an origin for that quotation, though. Would you kindly link it?

Kolanaki ,
@Kolanaki@yiffit.net avatar

It was literally in the wiki you linked to lol. Though I was mistaken, it wasn’t Howard Philip Lovecraft, but “Philip Howard.”

Philip Howard, writing a lipogrammatic appraisal of A Void in his column Lost Words, said “This is a story chock-full of plots and sub-plots, of loops within loops, of trails in pursuit of trails, all of which allow its author an opportunity to display his customary virtuosity as an avant-gardist magician, acrobat and clown.”

profdc9 , to til in TIL ~62% of the atoms in a human body are Hydrogen, and are as old as the universe.

Hydrogen is an electron and proton. I am guessing that most protons have been fully ionized many times since the beginning of the universe, thus not being complete intact atoms. Checkmate scientists!

If you break down that far, isn't everything as old as the universe?

h3mlocke ,

Yeah that’s what I was thinking…

PrinceWith999Enemies ,

I’m a biologist rather than a physicist, but I will take a swing at this.

Not really, although it depends on how you do your definitions. Most of the elements were formed by stars, which were themselves formed by the OG hydrogen, so hydrogen came first. So, first energy, then particles, then hydrogen, then stars and such, then oxygen and iron and all of those things.

I’m open to any corrections.

Ross_audio ,

When fusion or fission occurs you get new atoms.

It’s Hydrogen that’s existed since the universe cooled enough for electrons and protons to make atoms. Seconds after the big bang.

That’s most hydrogen.

It’s never been fused into heavier elements just still sticking around and caught in the planetary part of the solar system rather than the sun itself. Or any previous suns.

There’s some helium like that but most helium was formed inside suns later, and heavier elements all formed later in suns or supernovas.

CrayonRosary ,

Don’t forget neutron star collisions. Modern physics doesn’t think there’s enough energy in supernovae to create all the elements, so some must have come from neutron star collisions.

jol ,

But you don’t get new protons and neurons that way right? Higher nucleei are just hydrogen nucleei that got too cozy with each other.

Entropywins ,

More like 380,000 years after the big bang you still needed everything to cool down and forces to separate and lots of other really cool stuff to happen before hydrogen could form.

bitwaba ,

Atoms didn’t exist until 380,000 years after the big bang. Before that the universe was too dense for atoms to form and everything existed as a hot dense plasma where no electron could be captured by protons and neutrons. The protons that make up the nucleus of hydrogen did exist, it’s just that everything was too energetic to become an atom yet.

“All of the protons in the universe have been around since the beginning of the universe. Most of them haven’t undergone nuclear fusion”

Isn’t that good of a post title

Zorque ,

Maybe not for you, but its much more interesting for me, as it gives more info than "if you think about it, old things are old"

beebarfbadger ,

Yes, Neil deGrasse Tyson, you are very jaded and knowledgeable. Now let the rest of us have fun.

As far as I’m aware, protons don’t decay. If they formed at the beginning of the universe, they stick around until they get annihilated by anti-matter. But are we getting new protons after the universe formed? No idea.

Not me. I make my hydrogen from scratch every morning. Takes a while, but you can really tell the difference.

Given enough time, Hydrogen will begin to wonder where it came from, and where it is going.

numberfour002 ,

If it hadn’t been for hydrogen, oh. I’d been married long time ago. Where did you come from, where did you go? Where did you come from hydrogen, oh.
