Whenever I have a bad day and it gets overwhelming I always watch these and forget how small we are compared to the universe

The beginning of this video itself gave me goosebumps and made me think how small and nonexistent we are at the scale of the universe.

Audio cut out for me at 41:26 for about a minute

Jim is by far the best when it comes to science documentary

Thank you for not playing loud dramatic music in this video... We can actually understand the talking... Thank you!

I appreciate this scientist so much, he makes complex things understandable. James Al-Khalili.

Finally. A Big Bang explanation I can understand. For 45 years I’ve wrestled with an infinite universe coming from nothing. This video is the first I have seen that says it is non Euclidean. My teachers could never answer the questions I had about Big Bang. I guess they thought non Euclidean geometry wasn’t important enough to teach. The video says it was posted 1 day ago, but I added this to ‘watch later’ a few days ago. Non Euclidean geometry strikes again 😆

I love watching & listening to Jim

Long time ago found out how small and insignificant we are and that nothing I do actually matters for the Universe, so I never had a bad day since then😊

Love your well articulated and informative videos❤ Blessings 🙏🏻

Jim Al Khalili is one of the professors whose video-lectures on cosmology I like and enjoy the most. I have been watching his videos since i fell in love with astronomy physics and quantum physics. i hope he makes more videos.

Imagine , if Hubble was alive today, and he was taking a look at the deep field display, i wonder what he would then be thinking about !!!

aww, i remember beds on the roof in baghdad. nice memory

A FANTASTIC DOCUMENTARY 👏... ALWAYS A PLEASURE TO WATCH DOCUMENTARIES BY PROF. JIM AL-KHALIL.

Just magnificent !👌 👏 a true piece of art of knowledge!✨️ 👌

The sound goes MUTE at approximately 40:25 in and is mute for about 60 seconds right over a crucial bit! It’s a great documentary - please upload again. I want to see that explanation! Keep up the good work!

Jim is fantastic

Well done!

This looks interesting enough to fall asleep too😁

Thanks for this great documentary. I keep learning about physics not knowing a single clue about mathematics 😆. That's the beauty of physics I guess

Great doc

this was just amazing

It's cool how far ahead of Oppenheimer these renditions of small particles were.

Thank You

AAMAZING

Great.

Awesome 👍

Matter EXpands or Space Expands..............intriguing questions in my mind

I watched this video a few days ago How could it be released just 10s minutes ago?

Faced with this revealing reality of how small we are, will human beings have the will and capacity to eternalize as conscious beings, throughout this infinite space?

I lost sound from minute 40 on. Thanks for looking into it. Amazing content

GREAT

“Atoms form?” He mentioned. But, …by themself? So smart, so simple, but go deep you will find the most and ultimate question of the Universe.

Jim is really good in explaining science for people like me who are interested in science but have wasted their life by fallowing other subjects. I wish Neil Degras Tyson who by the way is great too took his lectures more seriously and got rid of his comedy style in science.

I guess thus video was already been posted

Subbed to too many W40k channels thought this said everything 40k at first

Audio cut at 41:26.

TKS

Is there a way to contact the creators of this channel?

I really enjoyed part 1 of this documantary but the staggering number of ads keeps me from watching part 2. UKposts is destroying science.

Why isn't space extra light and illuminated considering all the sun's that are up there,it's so hard to understand,but still fascinating 😊

Star Trek's Dark Expanse

❤

After melting gold down it’s impossible to trace. Scientists: We are watching 13 billion year old light on TV.

Disapointed.. you didn’t say how much sand Would represent the Milkyway. Now I have to count them myself 😅

Random pattern of distribution of energy looking like an explosion in time caused by the fact thathe universe can only do one thing transform energy

I saw this video about a month ago and this version has lots of bits cut out and bad editing. What's the deal?

There are 2 TRILLION GALAXIES...

This clip has been around…why the rebranding?

Why space is dark when there are plenty of ⭐️ stars 🌟?

I can't believe we're living on the outside of the planet . . . how dangerous is that !

Can I blow everyone's mind 😬🙏 nothing is something as we where able too give it a name 😊

I would believe you, scientists, that it is not as bright at night as during the day because the universe is expanding, if you would let me understand why I see the noise from the big bang on TV, but I do not see photons rushing from one end of the universe to the other. Why is the noise from the explosion cooler than the light?

What greater wonder is there than what lies beyond what our eyes and thoughtful abstractions can ascertain? I'll tell you with a question. How is it, I wonder myself, that historians have not revealed to us all along our human path the most life-quality-relevant and deeply dark pattern in human existence associated with the presence throughout human history of dark triad personalities in the human population, those wonderful folk that simply, usually deceptively prey upon the rest of us. Humanity's housekeeping must be our priority. We must devote our intellectual and emotional gifts to rid ourselves of the dark triad types that hold back humanity. I rant...because I am waning and care about the rest of you.

I still remember teachers at school mocking that there's life in space... it was book bashed we were the only intelligent species in the universe ... turns out they were indoctrinators not a real teacher that matters

I just wonder what exists and doesn’t for a time being

Its actually not even close.. all grains of sand times 250.000 (if we are looking for number of exoplanets in the observable universe)

1920- Arguing over there being only 1 galaxy. 2020- Lander on Mars! It took humans a million years to use stone as a crude tool. It took a further 50 000 years to shape the stone into tools, yet 5 000 years later we have AI probes on Mars.

It is up to 2 trillion galaxys as of a year or so ago, and is probably far higher.

While I enjoy these cosmological based videos,my 50 years studying Einstein's " reality" and especially as he defined in his SRT as much as GR, * think he made a number of mathematical errors, especially in assuming space is "defined" by the matter within it. An (near) empty box 8000 miles square contains no more space than one containing the planet earth and atmosphere. They are of equal size and volume. They are not of equal material density or the compressed field G surrounding the spherical earth within. It was not necessary to assume "matter" defines space, when a universal field (fG) is sufficient. If one thinks of fG as uniform in all directions within a completely empty volume of space,and then see clouds of atoms condensate from tiny edies of disturbance within fG, you get matter condensates, rather like a cloud that becomes dense enough for rain to condense there from. Think of matter as the condensate of gravitational knots and eddies that were the asymmetrical byproduct of some expensive "big bang" into possible an eco universal fG. The point is, Einstan's math on some of these issues described illusions. Consider C (speed of light constant). It can never be measured regardless of its reference frame of origin to exceed 186,320 mi/sec. But that only proves Heisenberg's theory of quantum measurement, not that light speed is fixed and not riding in a totally Newtonian universe. He demonstrated a 4 Dime suinsl world that includes time, but T is simply a measure of distance covered during some unit of time = velocity, always measured however in the reference frame of origin and only relative viewed by the quantum moment of the detection within the reference frame of its receipt. His math seemed to define a ^4D universe in a two D model. To me, fqG (quantum field Gravity) as a pressure force seems much more reasonable than simply pretending space and time somehow become more condensed in the neighborhood of mass condensates like a planet, sand grain, atom, star or galaxy. Furthermore the pesky problems of GR vs QMech seems to disappear when the universal ether is just faG with matter appearing in the twisted knots of that universal field in all dimensions. Time is irrelevant as it simply defined change, evolution of measurable differences between what was, what is and what is to come, the interesting definition of God by the way, Alpha, Present and Omega, or Jehovah to the ancient Hebrews. It's interesting that Mormon Prophet Joseph Smith not only defined in the 1830's the universe Edwin Hubble discovered, but also dark matter, dark energy and a far more massive universe than was then perceived. In any event, I love Albert Einstein. His contributions to our understanding of light and the photovoltaic effect, cosmology and our universe makes us think. But my senses say we need not go completely into his spooky realm of time dilation and variable measuring sticks when assuming our observations are relative, but not absolute truth in a quantum world. You can measure or predict location, but not both. Heisenberg was correct. It is why C will always "appear" to be fixed in the measuring reference frame as 186,320 mi/sec... But that may not be the Newtonian speed at which it is a tally traveling in its own reference frame vector when it is stopped and measured.

Why is the space dark ?

Infinite game for me

You can't put a number to it and say that's how many because it's endless...Imagine that...I can't even...you can't even say everything because that's not even come close to every of it...not an inch close..

How could space expansion be detected? All measuring sticks would have to grow with space, including your eyes.

So why did part 1 come after part 2? Lol

✌️✌️✌️

Elon Musk could buy a candy bar for one being from every galaxy 😮

Funny there's more micro plastic than there are sand and stars put together.

Prove it?

Think about how much more advanced we would be if half the human population hadn't been oppressed for thousands of years.

What about the Mayans and the other civilizations which mentioned about space stars and the universe

Everything = Nothing

The truth is Nobody' knows what's out there

Never mind fixed stars, get your teeth fixed

Bottom of the ocean 😂😂😂???

Great cinematography. However in 536a.d. something happened and they definitely already pondered this 1000 years earlier. And the Greek computer was dated around 2,000 years ago, which was basically a geared device with the constellations on it. The device helped men travel the seas. Anddd half the Egyptian ruins are exactly aligned with certain stars. I don't think people realize the level of understanding of nature and the universe that people had back then.

all assuming the earth is actually a globe..

Unwatchable. More adverts than all the sand and stars in the universe.

Someday, people will think we were so foolish to believe everything in the universe would fit in a single point 😂

No way!
