As astronomers search for life outside our solar system, they have to try and answer one big question: What’s the recipe for a habitable planet? We tend to think about the ingredients we encounter every day: liquid water, the protective blanket of the atmosphere, a sun that is neither too warm nor too hot. But there are other factors that are probably equally important: Earth’s cooled and hardened crust, its gooey molten guts, its magnetic field, its volcanoes and deep sea vents. These are the features that fostered life as we know it - they were shaped by unseen processes hidden deep within the globe.
In short, if we want to learn how life could arise on other planets, we need to know what’s going on under the hood.
But that’s easier said than done. As you drill down into a planet, temperatures and pressures quickly rise. Scientists and their tools wouldn’t survive a few dozen miles down, let alone a few thousand. So how can they study the insides of planets?
Enter NIF and OMEGA - by some measure, the two largest lasers in the world. They inhabit large warehouse-style buildings, and focus scores of intense laser beams onto the head of a pin. When facilities like these were first imagined, the goal was to create nuclear fusion - but planetary scientists quickly realized they could be used to investigate matter under core-like conditions.
The last decade has seen a flood of experiments - and the results have been bizarre. Nickel, a metal that conducts electricity, turns into an insulator. Water forms a hot, conductive ice. Hydrogen becomes a metallic fluid. Sodium, normally a shiny opaque metal, goes completely clear. These startling insights are helping scientists understand how planets form, and how they might evolve to support life.

Incredibly impressed by the way the concepts were broken down into manageable chunks, including going through the background to lead the audience to why we use lasers and how that experimental method falls in contrast to others. Masterful.
Vox is usually pretty good at that, and I'm pretty sure they won some awards for it on their "Missing Chapter" series. Or at least got nominated for one.
Wow! Adam Cole (Triple threat - animator, songwriter, host,) needs a raise - along with everyone else involved! I would think that this type of video takes a lot more time and money to do - And I have started to notice that other channels are beginning to put the same sort of increased effort into making fewer but better videos - I think this is a great trend if it continues. Awesome work everyone!
Literally the perfect example of “Quality over Quantity”
I thought you meant the wrestler and I was slightly confused for a moment
@@vincentd.9171 bay bay
Is he really? I like your name btw!
Ithought the song at the end was an oldFrank Zappa!gem Inever heard before🥷
I've loved Vox videos for ages - this one blows most of them out of the water! Just a succinct, enjoyable, understandable demonstration of an EXTREMELY complex topic. Great work 👏🏻
loved the nif jingle
edit: and the visuals towards the end when they were explaining the experiment in the amphitheater
7:33
Loved the visuals as well.
The play the same jingle before nuking cities.
*May not be entirely accurate
Astrophysics major here! This video is freaking amazing and I really appreciate how accessible it is, great work Vox
"As big as three football fields"
For Christ's sake, America, what does that mean in *normal* measurements?
america measures things in football fields, empire state buildings, elephants and olympic swimming pools
Just googled it, it's ~19.5 kilometers.
@@arry5276 what? It’s at most 0.329km. Or 0.146km if we stack them like in the video
@@arry5276 one football field: 91m x 64m or 300 feet by 210 feet
I'm a American. And I still don't know what that means.
as a teacher it gives me warm fuzzies that the one scientist interviewed quoted a single phrase from her second grade teacher that sparked her entire career
Any discussion of NIF has to include that its purpose is not fusion energy, but nuclear weapons research - after the test ban treaty, experiments that replicate the conditions inside bombs were the only way to continue testing and/or developing nuclear weapons.
Yep, was thinking about it.
And thank goodness too - they would never have gotten the money otherwise to do their research
they briefly mentioned it but did not give details
yup. and the defense department invented some of the tech required for the internet. you know, in case there was a nuclear war and all the military command centers couldn't talk to each other.
Good purpose. Both left and right wing voters are getting value from it. May their nukes be large and numerous.
We need more videos like this!
Just as you think Vox had reached the peak editing of RUclips informative videos, they go a step further
IT'S GOOD QUESTION GUY! Man I can't believe I'd forgotten his content, he taught me how to find the speed of light! With peeps! And a microwave! And a little bit of physics (just a little bit!)
*THE SUN IS A DEADLY LASER*
This was so beautifuly done, congrats to the motion graphics designer
The end track is to good, love it need the full thing
Definitely a hit single!
What’s the song ?
Likewise!
Walking down the street by Bruno hovart
What a wonderfully produced video. I’m amazed at how well everything was translated to us. Great job!
I love the way you made the intro music & sounds synced with the explanation 😂
Ah yes, 3 football fields. The freedom units of America.
😂😂😂😂
Adam Cole is for sure elevating his niche of Vox content to a new level. Standing on the shoulders of giants with his team who've been doing this for some time (Joss/Mona/Dion), and all the more impressive for it. Fantastic work, keep this up!
One of the most entertaining, informing, and enjoyable Vox clips i have seen in a minute. Awesome job!
It's always a pleasure and a privilege to watch extraordinary scientists talk about very complex topics that they are passionate about in a way that some layman like me could understand. The amazing storytelling and animations help a lot as well! Just impressive from all aspects!
I've been to NIF so many times on family visit days and every time is so interesting. They actually recently completed their initial goal of ignition, or the best their facility can do, and the tests are changing. A family friend used to work on the targets and explained them to me once years ago for an interview. The targets really are mind bogglingly tiny, as small as a hair like in the video, but they have layers of materials to help the reaction move forward! This video was such an interesting blast from the past for me, wonderful job vox!
Man, I'm obsessed with that end credits song.
Adam, we need this diamond track on Spotify please!
This is a great explainer! You got the scientists themselves, awesome animation of actual science, and you managed to take one tiny-sized experiment and enlarge it in a way that everyone can understand it. Please produce more videos like this! As an Earth-sciences student, I feel like I gained important knowledge from this video.
*NIF!* Man this video production was so good. Love the style of it!
Vox, i love your channel so much. My ADHD doesnt let me focus on classes, research papers, etc. but this is both informational and entertaining enough to keep my attention. And the editing omg!! Whoever decided on the jingle for "NIF! :D" deserves a raise and a hug. So good.
The animations were great in this one, kudos!
@Vox where could I listen to the song from the outro? It is magnificent! :)
This is one of the best examples of the type of presentation I came to love from Vox that breaks down complicated topics. Excellent job on this one even the song at the end!
Love everything you make Adam!
Super interesting, great audio, great visuals, great editing.
More please!
Great video :) Thanks. Everyone focuses only on the NIF result for the fusion, but nobody was so far explaining the experiments and details like this video.
This video was absolutely amazing, super informative and I loved the song at the end with the credits, props to the team!
Oh man that's awesome! I do high pressure laser compression experiments so it's really cool to see it featured on a channel like this!
what was the song at the end?
Very informative video. Love the content. Thank you for keeping us up to date with the latest info out there.
The editing and choice of music is amazing
I’m used to Vox bringing excellent videos which cover a wide array of interesting content…. But the outro for this video 🔥🔥🔥🔥 fire.
cant help but to comment again how i love this video, it's very well produced, edited, explained, broken down and presented. kudos to all the staff including the host of this video. wishing to see more of him soon! good job vox!
So well explained! Had me glued to the screen. And the music was just perfect!!
Excellent video. Concepts presented well, good visuals, charming presenter, amusing without being cheese. Kudos!
Thanks Vox for making great videos.
this is extremely well edited! more videos like this please
One of the most impressive videos I've seen so far. Immaculate job
One of the best graphics works I have seen in years. Must have went a lot sweat in making this video. Keep producing such content. We love you.
Loved the video! Also the song that Adam did, was real good and chill
Wow great video and *amazing animation and graphics.*
Adam Cole definitely needs a raise.
And music and producing and presenting and writing.
this was one of the best vox videos i've ever watched - so funny yet so informative
This video is absolutely amazing!! Keep them coming 🙌
The illustration work is seriously top notch!
Vox never disappoints! Awesome work as always!
Coolest format I have seen in a Vox video, congratulations! Thanks for the lesson.
This was totally great. Makes what am sure is a very complex topic extremely relatable.
this is absolutely incredible. brilliant animation work!
Loved the editing!
Wow! That was so informative and fun, love that y'all included the Star Trek bit. Great job guys!
Really enjoyed the video, especially the kind of hopefull mood thought-out it
Truly beautiful explanation. Thank you vox 💛
This was incredible! Amazing video!!
Adam Cole teaching us (scientists) how science communication to the general audience should be done. Great job!
Incredible research and production on this subject matter! Thank You
Incredible video, thank you so much!
I loved everything about this video! Well done Vox!
Brilliant animator and fantastic break-down!
Beutiful video Vox! Congratulations to the the production team. Bravo!🙌
I often just watch vox videos just because the qaulity and style of production is just so wonderously enjoyable. It's even better that this channel seems to exclusively cover subjects that I happen to also be interested in.
Some great illustrations and animations in this video
That editing is so good oml
The animations in this video felt different than in other Vox videos: I really loved them
Exceptional motion graphics and sound design on this video! Big props to Adam Cole and the Vox team 👏👏👏
Wow. Wow. That was just so incredibly awesome, impressive, mind-blowing!! The things that some humans can frkn manage to figure out leaves me humbled, excited and speechless. I’m so envious of what knowledge people will have 100 years from now… (permitting we don’t destroy ourselves before then)
That was totally awesome. Great work!
Amazing production!
I like the style (and substance) of those videos.
this is such an amazing video, the subtle humor, songs, the graphics, presentation and the *NIF* tune hahaha
Good job Vox. Excellent video.
Song choice killed it
Good job on this video. Just the right level!
Awesome video! Well done!
😜 Marjorie Taylor Greene will be investigating
Loved this episode!
This is so well done!
great topic, great presentation, I really liked it
Amazing video, I love the ending song.
That outro music is a jam! I need it as a single, or something...
Okay vox i see u w the budget upgrade
One of vox’s best videos yet. Well done team
Hey is it possible that a link could be posted to the song at the end? I absolutely love it haha. I’d love to jam out to some science/engineering tunes 🤓
what is the name of the song at the end? that song is great!
In the credits it says it's Journey to the Center of the Earth by Adam Cole (the producer of this video). But I can't find it anywhere. I assume that means it's something he made just for this video, but I desperately need a full length version, because it's so good!
Loved the song at the end.
9:02 ive been seeing so many different ways creators are using dalle2 as a medium. i love those Dalle2 atoms
Love that song at the end. Is that released in full anywhere?
This song at the ending got me, well played.
This was hands down the most beautiful Vox episode ever!
The nerdy groove at the end....I tip my hat to you Sir Cole. Btw, can I get some of that on my playlist?
Loved the production of this video. Keep it up Vox. We love you. Also, a message from 7 year old me: MORE MORE MORE
Best episode yall have made in YEARS
They just made the Death Star all over again but non-deadly
Good to know the location and the work being done in styropro's workplace
Top quality production!
Nice production.
Best Vox video I’ve seen in a while!
