- Theoretical physicist, author, broadcaster and professor Jim Al-Khalili sets out to discover the background of the rules of the universe and how humans discovered them. Al-Khalili investigates the laws that link everything, the concepts of energy, and how the concept of information relates to today's reality. Energy is vital to everything living, but what exactly is it? Out to answer this question, Al-Khalili proves how energy is so crucial to daily existence and its link to understanding the entire universe.

Energy is just a moth invariant compared to time, check Time Matters, 5th edition.
Dr Jim Al-Khalili is a brilliant presenter! 👍
The GOAT
The science professor who can go toe to toe with Dr Brian Cox. How lucky is England to have such amazing educators.
Brian Cox is an entertainer, not an educator.

Wonderful, thankyou. Boiling the kettle for a cuppa will never be quite the same.
Watching Jim Al-Khalili videos should be watched at least a few times to truly comprehend!
Jim, you are a true teacher par excellence! Thank you for taking the time to form this sublime presentation.👍

stunning documentary. as always really appreciate the beautiful work.
one of my favorites!...well worth rewatching on just about a weekly basis...thanks for uploading.
My favourite science presenter...
Why on earth were we not taught about the artistry of science in the early 80’s. It was all equations & exams. This thing is amazing. As is the mighty Jim Alkali
We were in the UK, I did physics, this is what we were taught in A level, they dumbed it down for those taking lower valued exams.
The technology access to creating and viewing all these media made a difference. It's a pity the youth of today don't appreciate this. I hope schools simply play this video in classrooms
It was planned by Marxist to dumb down the next generations.
You wouldnt be able to fully grasp these concepts without that basis of the boring stuff. So while yes it was much more dull even for me a late 80s kid, what they teach today us fsr more dumbed down. I have to teach my kids on top of it because its just unacceptably simplistic.
@DanielCruz-qu9jw yeah history especially i loved but had bad teachers. You could fire up a playlist on youtube now and get a very very good education on anything.
They do very much take it for granted. I thought the internet would make us all geniuses. I realize now how utterly naive i was to think that lol. The internet made people dumber! And more jerks.
I love this guy! I recently turned off one of his videos because someone had jacked up the music track to the point I couldn't hear Jim explaining whatever it was. Gravity, light, perhaps some notes on Newton...
What a beautiful way to look at things! Inspiring! Thanks 🙂
British documentaries are so good.
Beautifully done documentary! Keep up the great work!
I LOVE THIS GUY! My apologies professor, but Queefie is known to botch beautiful names. Your passion and energy is unmatched, and what beautiful, powerful tools for a teacher to possess in their arsenal, indeed!
Oh shut up...lol
@@veronicajackson699 Whatever "Veronica". See, I said your name, no problem...
Christ almighty.
Prof Al-Khalili has created many of the most interesting and instructive videos on CZcams. Every one of his creations is a treasure.
Fascinating! Thanks for posting.
entropy becomes how wave functions behave when they are "clumpy" lol I love it!
Awesome 👍Looking forward to the one on information, information entropy and how it ties to thermodynamic entropy...
Love this guy. Every video I watch my mind was craving for
I invented a machine what not need any fuel, also not need Sun light or wind, not need for ocean waves.
This machine work around o'clock.
Cheap and clean energy.
Will totally change all energy industry.
Patenting on the way.
Your the best.Please keep the new discoveries coming
Very nice documentary. It should make a person have great respect for our engineers.
Well put together....
This is so cool! Thanks!!
Beautiful, Beautiful!
Excellent!!!
second or third vision of that doc.... fascinating every time.
Excellent 👍 thankyou 😊
Thank U so much 👍👍👍♥️♥️♥️
Great Explanation 🙌😊❤️
11:31 amazing!!! Oh man I LOVE Britain🇬🇧🇬🇧🇬🇧 so much! Simple things...Even the Victorian kitchen is so lovely!
Great episode! I have seen this same episode on another channel. Good excuse to watch again 😊
As an engineer I owe a lot to physics to understand the basic principles of material world around us. This video took me a step forward to understand it better. Thanks a lot for this wonderful production.
Physics owes a huge debt to engineers. No physicist alone could have created something like CERN. It's the engineering behind it that makes it what it is.
Very good 👍🏼
Very cool
I really like this guy.
Thank you!🌈🌈🌺🌺
Now I finally understand why it's useless to clean my room. Entropy in closed systems will increase one way or another.
So far, it appears that the universe started as something tiny and started to expand to what we can observe and detect today. It also appears that anything we can observe or detect is made from extremely tiny particles which interact and combine with each other based on some fundamental predetermined rules. We also have identified quit a few of these extremely tiny particles and have identified quit a few of the rules these particles follow to interact and combine. Perhaps most of the particles and most of the rules but there may be more and, we also figured out that anything that we can observe or detect is made from the same basic stuff and we named this stuff energy. We know this because we have figured out how to calculate a value or quantity of energy for anything that we can observe or detect. It also appears that after the universe started to expand, no more energy was added or removed as it continues to expand. We do not know what the rules were that determined the amount of energy in the universe nor what caused the energy in the universe to start expanding.
The rules for how energy expands, transforms, interacts and combines cause energy to cycle from concentrated to diluted states. Although the cycles can be repeated almost to an infinite number of times, there will be a time when they stop because as the cycles keep repeating, the total amount of energy in the universe keeps becoming more and more diluted. We call this rule entropy. At some point in time, all the energy will become so diluted that it will not be able to cycle back into more concentrated states and we think this is when the universe ends.
We still do not know the rules before the universe started to expand and we still do not know the rules after the universe will end and there are probably still many rules that we do not know as the energy in the universe continues to expand and cycle back and forth from concentrated to diluted states.
What if the universe is rotatating, revolving around a center as it expands? We would see the same galaxies at different times in their lives. As we focused backward in time, the same objects would be found in different parts of the sky. That would mean the universe is less massive than we suppose. Your Welcome.
@@CPHSDC It’s always fun, entertaining and sometimes interesting to play the “what if games”. Sometimes they can help us think about new ideas but until we can find some evidence for the “what ifs” they will remain speculation.
@@Danny_6Handford I would look at galaxies and quantify, date them, arrange them along vectors in space time and see if any fit together. But I only have a pair of binoculars. ANOTHER WAY of saying what I'm saying is the universe is smaller than we currently construct it and some of what we catalogue are duplicates. Pretty weird. Subtract all that mass.
I am so jealous of those old tomes in that library. I would die to have just one!
Fantastic review 👍 great work, this should be in school inspite of history, since only science is changing the world for the better! and nothing more.
But history can warn us (if we choose to listen). It can also inspire the future.
@@GavinM161 People learn only on failures not from the frontiers of science. Just look in the past (constantly) - wars, colonialism, slavery, tyrany, imperialism, dictatorship, regim, earthquaqes, tsunamis, poverty, famine, death. Science gives new possibilities, wealth, richness of life. We should see bright future in front of us not the dead end behind. Einstein said that we can not solve problems with the same way of thinking that they were created (stuck in the moment and can not get out). It means that we should study something new e.g. science. Science has advantages even over the religion, since religion can give you nothing and takes everything e.g. life, and science can give you everything and takes nothing e.g. life.
How history can inspire the future? you are going to be great worrior, hero, crusader, king, mass murder, dictator, knight or saint? The greates threat for us, are we so nothimg to warn. If you look at the history from industrial revolution everything has changed (1700). Even now - blue led light reduces the consumption of coal and green house effect, heat pumps generate energy from air, PV gives you power from sun, WWTP produces methane and clean sewage. Everything is in the future mind not in the old history - but first, you have to create it (the most difficult part with no copying - ethos).
It's been the 8th of march and it is still here?
this is going to be another banger!!!!!! and that's the way the cookie man crumbles🍪🍪🍪
😀😀😀
I didn't know yevgeny prigozhin did documentaries,so great
1:26 What is the hauntingly beautiful music at the beginning? Would love to listen to it in its entirety!
I can't help unfortunately but I agree it's fantastic.
Jim I have a problem, if energy cannot be created or destroyed how is it possible for the universe to cease to exist. Something is missing in this equation.
So energy self perpetuates ? If there is a finite amount is that amount constant?
Can someone explain if energy changes from one form to another so if heat changes to mechanical energy and this turns into let’s say sound what does sound change into and so on? What was the heat energy before? Can be stored as in coal?
Water / Design shape / location: my proposed solution to hold heat of the reactor
"In any system of energy, Control is what consumes energy the most.
No energy store holds enough energy to extract an amount of energy equal to the total energy it stores.
No system of energy can deliver sum useful energy in excess of the total energy put into constructing it.
This universal truth applies to all systems.
Energy, like time, flows from past to future" (2017).
Humankind....you mean mankind
Jim said ' without food we die ' I've just written it down, lest I forget.
Need 4k
Fusion was still 'only a few years away' even back when this was created. :-)
Law of entropy predicts the work of an immensely huge power WHO set the universe into perfect order before saying GO and it started happening consuming the immense stored energy.
If energy is finite & if it flows from concentrated to dispersed, then both of these depend on a container. So therefore the Universe would be the container & it would have defined edges, right???
just ask what you do for cooling
Carnot's idea of thermal energy or mechanical force caused by heat transfer, or more exactly speaking, accelerating random motions of air particles, is applicable to a limited and constant volume of space, but can never ever be any sort of natural physical force in the infinite space of the universe as you guys have subjectively claimed
It disturbing that BOLTSMAN expedited his own entropy.
Damn....I hate that such brilliance was plagued by mental illness.
The Story of Entropy is Nuanced
Bc I’m well versed in science I knew most these concepts but I knew very few of the names…I’m a learnaholic 😊
What if the universe is rotatating, revolving around a center as it expands? We would see the same galaxies at different times in their lives. As we focused backward in time, the same objects would be found in different parts of the sky. That would mean the universe is less massive than we suppose. Your Welcome.
What if I was rich?
But mass by its force of gravity imposes aggregation of matter. Is matter’s gravity the reciprocal of energy’s entropy?
Let's get physical 😊 🎶 🎵
Sometimes I had a good time
I agree with Libniex, that a wise creator set things in motion almsot Aristotelian. A prime mover - cause snd effect. I know you are a "humanist" so Theologen and Philosoher, you left Theologan out when your repeted it. If you go to the Einstein Museum here in Berne you will see that one of his favorite toys as a Young Man was a steam engine;
Unimaginable things huh 🤔
The Cambridge professor is where l got beck and call from
the reason the heat doesn't go back to the source is because of the Higgs mechanism. as a result, things got "clumpy" and so, did the wave functions. heat is merely too many wavefunctions in a given tensor.
Adverts every 5 mins, totally unwatchable.
CZcams red is the best investment I have ever made. Makes YT actually enjoyable if you can afford an extra subscription. I personally value YT over Netflix and other streaming services.
Love the presentation of information in these videos, but there are such gaps for the newbie like me. At the 10 minute point, yu talk about the need for energy and then bring up the advent of the steam engine but never describe how steam energy powers things... I gather you burn some wood or coal or something that boils water and makes steam to turn a wheel... but I don't really know...would be nice to get more granular so people today could understand all the exact ways that power (electricity) is made...
Is the energy driving the expansion of the Universe self sustaining? Is the expansion a steady one, or is it in waves, or in slow pulses over time? I agree with with Marttihelevirta4149, no one has proved a closed system, or even proved (satisfactorily) a multiverse, of many Universes, or anything else (yet)
The multiverse idea is generally considered to be speculation, not an actual scientific theory, since there is no possibility of it being tested. The expansion of the known universe is currently thought to have started extremely rapidly as a process called inflation, after which it then continued more slowly and still is doing so. This ongoing expansion requires energy to drive it. It's called 'dark energy' since we don't know what it actually is or where it comes from. There isn't any good reason to think it might be manifested in the form of waves or pulses.
The rate of expansion is increasing over time.
What if the universe is rotatating, revolving around a center as it expands? We would see the same galaxies at different times in their lives. As we focused backward in time, the same objects would be found in different parts of the sky. That would mean the universe is less massive than we suppose. Your Welcome.
When the universe reaches maximum disorder, it will be in a final ordered state, yes?
Without heat life couldn’t exist
Somethings are not made of energy but dead matter but eventually comes alive to something else
Disorder means uniformity of energy and matter here
Jim Al-Khalili’s style of documentary descends from Jacob Bronowski and Carl Sagan… beautiful, carefully paced, thoughtful. This style of documentary seems to be gone now.
I don't know if anyone can compare to Carl Sagan. Unique and unequalled.
a billion dollars&a billion watts ta make a bit of energy? jeezsh!
We can not be using fusion to produce steam. Steam is totally antiquated. We must do better.
Could be great. But moves along too slow with to many ads. Such a shame.
Great leaps?
Life seems to defy the 2nd Law of Thermodynamics.
why this spooky ambient music, im trying to sleep :D
I love the documentary explanation we can learn more , but looking CGI ON EARTH NIGHT AND DAY IS NONSENSE
It's just a visual aid 🤦♂️
Quantum information, Quantum entanglement,
Are, fundamental, underlying of Reality.
Quantum Mind emerge, Quantum Body emerge,
Mind and Body entanglement.. Consciousness emerge.
Spacetime emerge, Mathematics Emerge, Holographic principal.
energy is not created or destroyed, its differential geometry.
Fission is simpler than fusion by a long way. Enough for our needs.
So was wood, once.
Thermodynamics will forever be Carnodymamics to me now
One of my favourite Physics videos but I’m afraid it’s been ruined by the over usage of adverts, pure greed.
As insightful as ever. But what on earth is energy to begin with?
Matter 😉
@@leftmono1016 Thanks, but my understanding is that energy is something relating to "the ability to do work" (per my high school science teacher - hence my initial question:). But if you're right, what is matter - or specifically, what is matter made of?
@@akpanekpo6025 - I’ve just done a quick Google search and the first article I read includes a piece by someone from my small home town in England. Bizarre coincidence.
I didn’t really understand the article fully enough to summarise to be honest.
Interesting topic though!
@@leftmono1016 Thanks, and I’m glad I’m not alone😊
I’m almost sure I misunderstood him, but I recently watched Roger Penrose describe the weirdness of matter by first tapping on the wooden arm of his chair (to demonstrate its solidity) before explaining that if you could slice up the wood beyond its elementary particles (i.e., quarks, etc), you’d be left with nothing but mere mathematical probabilities. In other words, the supposedly solid wooden chair you’re sitting on is no such thing at all. That’s my definition of weirdness.
@@akpanekpo6025 - yes quantum physics is fascinatingly weird!
The illusion of solids amazes me too. Nothing is really as it seems.
rust never sleeps
I can't help wondering why a star like our sun burns for billions of years. Why doesn't it just go boom? Conversely, why can we only sustain a fusion reaction for a few fleeting seconds? The two questions are seemingly at odds with each other!
Technically the sun is going "boom" at every instant since its ignition, only there is so much gravity the matter and energy is all in equilibrium. When the equilibrium is broken that is when stuff like supernova and red giants happen.
The sun has acces to billions of tonnes of matter and insane pressures and temperatures at the core, a natural fusion reaction... we kinda have to science our way to fusion with technology.
The heading of this video uses the words "Laws that govern our existence".
Since all laws are created principles, then anything created must of course imply a creator. God.
So are we being blinded by scientific speculation as opposed to the reality of being ?
How does one change energy into $$$?
It is an energy SLOPE on which we depend.
The differential of energy.
Get it correct!
He should pay attention to the road while driving
THIS IS N-O-T NEW.
🤦
WHO SAID I-T WAS?
Why do stars have so much power
I've been wanting to join your Quantum biology team but I assume that you ignore me because I believe in a creator. I don't believe in a Creator like a majority of people would think of one. I think if you're a humanist and you believe in love and that's good enough. But like I said, be leaving in love is for me is akin believe in a beneficent creator
The average person today cannot make fire if their life was on the line
