What's the Universe Made Of? FULL EPISODE | NOVA Wonders | PBS America

[@mtmmf7632]

I love PBS space documentaries…

[@TheDavidlloydjones]

Are they planning on doing space documentaries?

[@mtmmf7632]

@@TheDavidlloydjones they have one called “Black Hole Apocalypse” that I felt was really good.

@@TheDavidlloydjones Exactly, it would be a nice change from this formulaic muck.

[@laughingoutloud5742]

I'd love an update to this episode. So much more to learn about gravitational waves and the JWST has contributed to the search for answers ❤

[@greg9404]

Yeah this is from 2018.

[@ThorPalsson]

I love PBS Nova Thanks for sharing with non Americans

[@larrywalsh9939]

What I want to know is why a documentary about physics is being hosted by a mathematician, a neurologist, and a computer scientist. Were there no actual physicists available to host a physics documentary? Perhaps somewhere there's a dentist's exhibition going on somewhere in the world, being presented by a tailor. Because after all, why would you want to get a dentist to talk to you about dentistry? It's not as if tailors know anything less about dentistry than dentists.

She's not just a computer programmer, she's an astrophysicist. This isn't the stuff you should be watching, chump. Lol

[@GlenADahl]

could it be that dark energy is going into a round-and-round orbit?

[@kimweonill]

Mind blown. Thank you so much.

[@MrTorleon]

Interesting and informative. However, latest findings by the James Webb Telescope has really excited the space science community, as it seems our understanding of the cosmos is requiring a radical reconsideration - but that is all good :)

Why must there be music playing when people are speaking?

[@lindsayparker2965]

Dear PBS, excellent content, but please put the year of publication in the title of your YT videos. With subjects such as this one where new discoveries are made daily/monthly/yearly your viewers need to see this context. Ultimately, without knowing how up to date the info covered in the video is, it is a form of misinformation. (And before anyone mentions it, yes I know the year or publication is buried in the credits at the end... but it needs to be more prominent)

[@jazzy8330]

so basically we know fuck all

[@Kaib902]

Well it's dark and it's some type of matter and/or maybe energy and if it's not lit you can't see it but if you light it you can kinda see it.....again we can't see it so its dark, we don't know what it is but it's matter or/and energy maybe 😂😂 that's what we know

Star Formation is the beginning of the Universe Creation held in the form of Milky Way.

[@alex79suited]

That's a mistake running the clock backwards doesn't mean that everything was closer together that's WRONG. Galacty can form wherever there's enough material to form a first star. Pure hydrogen stars are super massive and do not last long. That's a fundamental mistake of the big bang theory. I'm sorry but it just is. Lots of little bangs. Each galaxy had its own bang. Galacty are a closed environment. I'm Alex 79suited and I support this comment. 💯 percent. Peace from Canada eh. 🇨🇦

Turned it off immediately. Only one section relates to the title, and in a typical American bargain basement pop-science way. I'm off to the Watching Paint Dry channel instead.

Have those who disbelieved not considered that the heavens and the earth were a joined entity, and then We separated them and made from water every living thing? Then will they not believe? in the Qoran

[@Milos_Adventure]

since i was a kid i always wonder how this stars planets are made and is the outer space is never ending no bounderies i always base in science and i love it i ask my parents before since i was a kid hwere humans came from they say god created us from adam and eve that i always LOL just because why they always believe in a myth a fairytales written on a book made by religios group with no piece of evidence its mind blowing

[@zakirhussain-js9ku]

At most deep level Universe is made up of submicroscopic quantum particles of mass, electric & magnetic charge. Whatever happens in the Universe results from interactions b/w quantum particles. When in motion these quantum particles carry force, energy & momentum in the direction of motion.

[@tindahannimark]

What will happen if it's stop expanding?

[@pallehansen1145]

It would eventually become static, or maybe even start to contract, ultimately resulting in a big crunch 😬

[@speedoflight3539]

As far as we know Universe is made of Elements and Space lot of Space in between the elements in Space. Life as we are and every other life around us. Enjoy

[@roy2689]

smiley faces in space? whats not to like...😃😃😃😃😃😃

[@WassimMohamed1985]

Is it that artificial?!

[@geogoes360]

I think dark matter is just a space-time anomaly that creates the illusion of invisible mass. If mass creates a space-time warp, then vice versa should be true, a space-time warp should create the illusion of mass.

[@pallehansen1145]

Interesting theory, although there is a problem with that. Something must be causing the warp in space time, and since we agree it isn't mass, it must be energy. Thus, you still end up having to introduce some form of energy to cause the warp, and then we have dark energi again.

[@geogoes360]

​@@pallehansen1145That would be the version according to what we know about space-time at the moment, but perhaps space is able to compress in certain areas, just as it is able to expand between galaxies, and this creates that illusion that there must be matter or energy that makes it compress, i.e. that illusory dark energy/matter.

[@eschewobfuscation.]

Sound engineering is horrible. One cannot hear and focus on the narrative of the speakers from all the sound effects. It is a common issue in many recent documentaries from PBS. Someone should dial the noise down, and the vocals up. This isn’t a musical.

[@leymealea]

❤❤❤

[@karlc8808]

This seems to be the way religion was dreamed up.

I would love if dark matter is stuff that has reached the fift state of matter

[@TheDavidlloydjones]

Whizzz. BANG. BOOM. bom-bom-boom. Wugga-wugga, this is exciting. This is real SCIENCE. And it's modern, too, and we know that 'cause the, uh, music is ELECTRONCI!! Yay, electronic! Yay SCIENCE. Yay wugga-wugga bom-bom-boom.

[@JJArsenault-ys5yy]

Dark matter/energy + space/time = black hole

[@siphotheguy1870]

The universe is basically made of star poop.

[@MrBenzeneRing]

I have question to @Nova. How can we claim that universe is expanding? We don’t know the direction of movement since we don’t have reference point. If universe is expanding faster and faster then isn’t its getting pulled into something or at something? May be we are looking at it in wrong direction? Who proven its expanding and NOT “CONTRACTING” ?

[@laughingoutloud5742]

Umm...did you watch this episode? All the answers are right there.

[@jimmylee695]

Any objects giving out light (electromagnetic radiation), we can tell if it's moving away from us or moving towards us by the 'Doppler' effect. So the light will be bunched up towards the blue end of the spectrum if it's traveling towards us, and stretched out if it's flying away from us, and almost every galaxy is flying away from us. Also, the farther out, the faster it is receding away. There are galaxies so far away that it is flying away faster than the speed of light, which is allowed because only the space in-between the galaxies is stretching faster than lightspeed.

[@demscastillon]

Light is the answer

[@Kaib902]

Have you ever seen an explosion, it expands in all directions, not trying to be rude but this video might be to advanced for you if you still don't understand that

[@ykkfamily]

Boooooring... Done! Gone

[@youtubeisnow1984]

one of the more lame segments in science I've seen... waay better stuff out there... I have no idea how this got into my recommended list... not surprised by the low number of views.

[@migueleckstein2213]

EINSTEIN never said that the entire universe was a single galaxy , not he said that on his equations and if you say that the universe is a single galaxy; do not mix EINSTEIN with your personal opinion ever since pbs got big $ DEm funding, there is a chosen narrative or even may be, $ Science for sale.

[@croozerdog]

sounds more like a mistake than pushing some agenda, video seems pretty okay in covering the basics in an interesting way
