The Webb telescope wasn't looking at the beginning of time, THAT'S THE WHOLE POINT!!! Several galaxies that Webb documented were well-developed spirals very nearly 13.6 or 13.7 billions years old, and which seemingly formed only a few hundred thousand years after the "Big Bang". But this is a problem!!! According to current theory, that is NOT ENOUGH TIME for such galaxies to form. Conclusion: THE UNIVERSE IS OLDER THAN 13.8 BILLION YEARS OLD, AND POSSIBLY MUCH OLDER. Such misleading headlines and assertions only serve to further confuse a cosmology that's already in the dumps!!! The Big Bang theory no longer explains observations, and it should be questioned now more than ever. That goes especially for the current estimated AGE of the universe, which is NOT supported by the new data.

Technology can only carry us so far within any field of study before we cannot advance any further and we will be left speculating from there on. Thats whats going on in astronomy right now or seeing so far into the past, or how far we can see in any given direction or how we keep finding new smaller building blocks of the universe until we get to a point we cant look any further etc etc. No field of study will ever be complete.

This has really helped me get rid of the deterministic view point I had developed over my college education and helped me by giving me hope that I would see my Dad again in the afterlife. I would even settle for knowing that he was reincarnated. At least then, he wouldn't be gone forever. I miss him every day. He was and is the reason I became a scientist in the first place. Thank you.

I know exactly how you feel, you are however pretty much your dad. All he gave you in spirit and upbringing and his genes. Even though he isnt here he is still here in you and even if there is nothing after death you had an exclusive opportunity to know him and yourself thru life and as we turn to atoms we feed life giving other life opportunity to feel the love and sorrow.

Given how relatively young humankind has developed in this universe, it’s ludicrous to think that there isn’t a much much older intelligent civilization/world(s) out there in those different and distant galaxies. It’s actually mathematically impossible that we’re alone in this universe.

[@ayandey137]

Mathematically impossile? Can you explain?

[@mai3cle]

Improbable might be a better word. Mathematics is about “proving” things yet how can you prove something is impossible, unlikely maybe but proving a negative gives you almost infinite options. It always seemed unlikely that we could be the ONLY sentiment life in such a vast cosmos but when you consider that humans have only existed for a blink of an eye in the universe time scale so for us to be able to discover/communicate with another life form has so many variables that would need to align such as the same time period , close enough for communication to travel within such a time frame plus a type of “life” that we could actually recognise and interact with.

[@skunkgucc]

Global military burden (GMB) is only 2.2% if you can believe it (that might be a bit conservative of an estimate, imo) so the question is less of a "collective resources being squandered" one and more of an ideological one, and some kind of globally-minded "progressive" technocracy is pretty much what we have now in most wealthy countries... so when people fantasize about some sort of vague techno-utopia I think it rarely goes further than that- a fantasy.

Suggestion: It would be great in every new video, the Background and/or Introduction part shrinks a bit more than previous videos. And basically the video gets into REAL NEW material for presentation.

that bites reality in a few ways - there has to be different writers and people at work on each episode .. it is way too well done to be made by 1 single team. so no team can really estimate how much the viewer knows at a given point .. especially since its likely not possible to do the videos in any kind of fixed order

Yes, instead of just unwinding all these animation clips to leave the impression of knowing everything.

[@Jabranalibabry]

They're actually only seeing graphs and data, bro. Two popular methods: one measures the star's woble as it rotates because planets pull on the star too but it's a very tiny woble. This only works to find big planets like Jupiter. Second method is to see the spectrum of the light the star emits, when a planet crosses it there is a very tiny shift in the spectrum as the atmosphere of the planet has molecules that react with the light and subtly shift it. Hope it helps! Both have their problems and nuances.

[@RavingKats]

​​​​​@@HistoryoftheUniverseI meant the notion that anything beyond 62 billion light years and the light would never reach us because the expansion rate of space to us is more than the speed of light. The furthest stuff we are looking at is 47 billion light years away by now (though we can see back 13.3-13.4 billion years back when the light left it). This is a miraculously close margin. If you calculate the size of the universe when it may achieve heat death, and what percentage of the total age of the universe to that point has gone by so far, it is astounding that we are now in a moment where the cosmic horizon is slightly closer than the vanishing point where no information could EVER reach us. We can in this moment see to the beginning but in the grand scheme of things only a tiny tiny bit longer. We exist in a near perfect window of time for it. I am explaining this all poorly I feel, but eventually in enough years where the furthest object has gone 17 billion light years further away plus the number of years of the age of the universe at that point beyond that time has gone by in addition, the beginning of the universe can never be seen again. Does that make sense? We are within that tiny band of time. With the rate of expansion accelerating, I cannot really mental math when that time will be, but age of the universe so far is a sizable fraction of that total time. Napkin math tells me 4 billion years from the fall of spot, so like 21-22 billion year old universe and we could not see its birth, and we are 13.8 billion years into that total time. Please someone correct me if I am wrong on any of this. So, 2/3 into it.

Great video, thank you. Top prose, top information, top clarity, top clarity. Top of the Universe. "Rara Avis" - our predecessors used to say of something which was hard to come by, something of rare beauty, literally a rare bird...

I love history of the universe, it's one of my favorite channels to watch .

[@carlknibbs2849]

Love your content always amazing thanks

[@iRiShNFT]

Thank You

[@anehakansson7771]

Brilliant, as usual.

[@RX552VBK]

Excellent video. I enjoyed every moment of your hard work. Thank you.

I've been waiting for so long for a HOAT episode about James Webb! It was great indeed! Love this channel

[@Just.A.T-Rex]

HOAT?

[@Jesse-cw5pv]

Webb has such amazing engineering. Worth it for those amazing pictures

[@hughlion1817]

It's truly a feat of engineering that even despite the 100+ independent failure points that could have arised during deployment, it still managed to end up ok. Almost 30 years from announcement to deployment but yes absolutely worth it!

[@charlie-george]

Loved this one

[@youlookinalittlesussyovert4260]

Babe wake up, HistoryoftheUniverse just posted a new video

[@SofaKingShit]

Don't wake up babies.

I love how the paper's title referenced one of my most favorite bands.

[@anjunatony]

What an amazing documentary. Seriously great job 👏

[@Ezekiel903]

we know that energy can appear and disappear from nowhere, but that such a mass of energy appeared from nowhere to create the universe is very unlikely! first they explained the big bang with a singularity, now quantum fluctuation! I think singularity is only a word for "we don't know".

[@douglasrowland3722]

Don't worry yourself about it. The Truth Shall Never Vary. The only way the Universe could have come into existence is by A guiding Intellect that controls Atoms and molecules and energy..A designer that is not made of matter and can be Everywhere At Once This Intellect is The One that lit the Stars and hung the Planets

[@Tyler-rj7bq]

strange time to release this, guess ill have to go to bed at 10am

[@CamiloJamesGuitar]

What an awesome documentary! Will be showing this to everyone I know 🙏

[@AshleySmith2-lo7oq]

This is no shade to the channel but I find these videos so great to fall asleep to! Partially it is the narrator's voice (is that a Welsh accent? It's quite mild if so), his cadence and rhythm is soothing. And it is the subject matter, which I genuinely find fascinating. I also love falling asleep to Attenborough's nature docs, from every era. I can't put on Planet Earth if I plan on gettinh anything else done that day, cos I know I'll be dozing within 20mins. Please keep making these excellent, informative, horizon expanding videos!

[@Numba003]

Thank you guys for yet another excellent episode! I remember being quite excited to hear when Webb had finally successfully finished deploying (not to mention launching successfully in the first place). I hope it continues doing good science for a long while yet. God be with you out there everybody. ✝️ :)

[@tuberroot1112]

"not to mention launching successfully in the first place". Yeah, not to mention. Like they managed not to mention the name of the "massive rocket", not once but twice. Quite deliberate. I wonder why ? Oh, it was not a MAGA rocket. It was European with French boosters.

[@aaronpotton2641]

I get so excited when you post a new video, I've watched every video on your channel multiple times over and they never get boring. This is the best channel on KZbin in my opinion 👏
