Hi Spark! I always liked documentaries with Jim Al-Khalili! But... I have a question for you! What do you think about that book which claims to have figured out what are and how work black holes. According to it those might be very brightly shining objects that become invisible exactly because of the laws of physics. Also, this book suggests a new idea for the origins of the Universe. According to it, it is eternal and uncreated and that is the only way it could be. The book describes the philosophy behind that. It it logical though. Also, the book describes tides in a completely different way. Yes, it still is because of the Moon, but in completely different way from what we think today. Among other things the book looks at failures of flat eart theory and hollow earth theory. It even addresses the question what is truth... Anyway, what do you think about those theories? The book is titled as "NEW THEORY OF WHERE THE UNIVERSE COMES FROM AND HOW IT WORKS". Also, the book claims to have figured out the true pattern of Magnetic field and how it works... Also, the questions about free will and Astrology are discussed in this book explaining why the latter should be taken as seriously as weather forecast and the free will is possible only within certain conditions. The most important of which is - we have to understand the reality around us... Its author uses a funny pen name - george warehouseman... Possibly to trigger some unstable PhD's... ha ha ha Also, the book addresses questions about what is good and bad, what is Truth and many, many others.

@vladimir putin is andrei panin jfk is jimmy carter nice dude. Love that you don't just accept facts and are trying to disprove what everyone's " normal" point of view. But one important feature of science is to question yourself as well. In flat earth - Where is the center of gravity? What is at the edge of flat earth? If you question yourself and others you'll get closer to the truth

The one about information changed me

why always the need to compare things... now you insulted both of them

​@@seekter-kafa You don't feel the need to compare things, others do. I don't eat pork, others do. It's called the world, dude, and it's filled with possibilities. A simple comment, done with good intentions, does not reduce anyones greatness. No one was offended. Sagan is dead and Jim is not reading this comment section. I just mentioned two people that summon in me great admiration and gratitude. All is cool dude, just relax, go for a swim in the sea, or climb a mountain, and the unbearable pain of external comparisons will be gone...

@@bartolomeugusmao4445 no wonder this world is going to shit

@@seekter-kafa Man, your world is going to shits, not mine. I'm cool. Is your world going to shits because people keep comparing cientists?

rightly said.

FYI, If it wasn't for the USA we would be speaking German.

@@whirledpeas3477 German sounds like an angry old man

True!

I agree. Love this guy. I've seen several of his vids.

hehe

Anthony Andrea Be well

@MeMyself AndEye Are you some kind of conspiracy theorist, flat Earther nut? What exactly does he say that's untruthful?

it paints a bleak picture, doesn't it? I encountered it during my chemistry studies - along with the physics (such as thermodynamics, and esp entropy as explained in this video), the biochemistry, which showed to me that we are nothing but chemicals reacting according to laws of physics, is difficult to deal with at first. The understanding that all that I (or you, or anyone) think, feel, do, want, hate, love, all of it is simply a chain of chemical reactions performed by complex structures composed of only a handful of different elementary particles, can be very depressing. Not even in a sad way, but more in an apathetic way. I kind of learned to ignore that aspect of reality over the years, but I would be lying if I said that it didn't affect the way I view life.

@@SMPKarma encountered this in biochem while trying to be a medical job. It gives you a weird lens on even though it’s all chemical reactions, the energy of people is real and therefore everything derives meaning from that, what we give the energy to all that. Entropy and the connections you can draw out of it to apply to life is interesting

I’m not sure sure it’s what happened with it lol lol 😆 I’m oooooooooo

Here's how my dad described entropy to me. A whirlpool high in the mountain stream fills up with rocks. The snow melts, the water rushes down causing the whirlpool to swirl. Grinding all the rock to fine sand. This sand is concentrated in a sandbar year after year and eventually lower levels are compact ed. Dirt clods out of that level are eventually ground into fine dust by heat, cold and rainwater. When this dust is dry it flies up in the upper atmosphere, where each Mote of dust has water crystalized around it forming ice which then falls back to earth and becomes rain.

@@SMPKarma To be a top down and truly great physicist, you need to be a top down and truly great mathematician. Here's the CLEAR proof ON BALANCE. ULTIMATE, CLEAR, BALANCED, INTEGRATED, IRREFUTABLE, AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/energy is gravity: Consider what is TIME. E=MC2 is taken directly from F=ma, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS the rotation of WHAT IS THE MOON matches it's revolution; AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); AS the stars AND PLANETS are POINTS in the night sky ON BALANCE; AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Great. Consider WHAT IS THE EYE ON BALANCE !!! Great. c squared CLEARLY represents a dimension of SPACE ON BALANCE. GREAT. Consider TIME AND time dilation ON BALANCE. Consider what is THE SUN ON BALANCE. GREAT. Indeed, notice what is the orange AND setting Sun ON BALANCE !! ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Consider WHAT IS THE EYE ON BALANCE !!!! GREAT ❤️❤️❤️❤️. Finally, what is lava IS orange; AND it is even blood red. Excellent. By Frank DiMeglio Consider what is the man (AND THE EYE ON BALANCE) who IS standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Indeed, in identifying or considering what is THE EYE/EARTH balance, what is THE EARTH is ALSO BLUE. Great. NOTICE: Gravity cannot be shielded (or blocked) ON BALANCE. Magnificent !! Water flows downhill. Great. By Frank

These documentaries by Jim Al-Khalili are like comfort food for a hungry scientific mind. ;)

@@BillAnt: Yes! I hadn't thought of it that way. But these videos are like really, really good chocolate cake for my hungry, (non) scientific mind. I just wanna know how stuff works! And he's amazing!

Reply to Ed. Many questions. 7777wavesflow@gm

you can like Billy Madison!

No, don't go back to the dumbing-down school system. Don't be ridiculous unless you need the piece of paper. Do your own research online and get the knowledge you want/need.

I’ve thought the same thing. A lesson for everybody who has big ideas. Don’t give up no matter how dark it gets. don’t listen to the haters

The proverbial thin line between genius and insanity is manifested here.

Makes me so sad that with such a great mind, depression could stand in his way and ultimately make him doubt and fall into his own darkness. He missed out being lifted into the light by a few years..... so sad, he would never know, but leave with doubt.

Entropy in a man --- the self destruction of Bolzmann, the entropy if you will.

That's fucked

There is a reason for that. Complex concepts require more than just flashy pictures. ;-)

You can say that again. All this knowledge at your fingertips. Only a click away. Rate of discoveries will skyrocket! And some will be by AI-enabled computers.

“Have”. Happily, we DID have rich presentations which explained complex concepts. But then, sadly, the fuzzy-thinking leftist fruitcakes took over most of America’s academies.

@@andiofski2653 Dude, the rate at which you can assimilate information is not limited by any external factors, right now. My university had over one million books in the science library. Just how many of those can you read in your lifetime, let alone understand? ;-)

@@wiltonsmith3397 Look, Ma! There is the kid that didn't go to university. ;-)

gee mr murgatroyd, i never would have guessed without your help.

Yes, but matter is also spreading out. The Universe is expanding at great relative speed. I would argue that matter clumping together is a local phenomenon. You thoughts?

​@@pas9ify - Indeed clumping of matter by gravity and electrostatic charge is a relatively local phenomenon. Looking at the big picture of the Universe, ultimately it will end up in total entropy (the Big Chill) due to matter always seeking out the lowest state of energy and randomness.

@@BillAnt Thanks Bill!

I know right! He says two sentences and then walks off

Yes. I noticed that :)

lol thats like a mic drop

I can't un-see it, now!

@@sosyl BALANCED attraction and repulsion is fundamental regarding what is physics/physical experience, or there wouldn't be SPACE OR TIME. BALANCE AND completeness go hand in hand. What makes gravity, ON BALANCE, a constant force is that it cannot be shielded (or blocked). Gravity is ELECTROMAGNETISM/energy (in and WITH TIME) consistent WITH what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE. The stars AND PLANETS are POINTS in the night sky ON BALANCE. SO, a photon IS at the center of WHAT IS the Sun; as this would then CLEARLY be consistent with the requirement of time AND SPACE. (Consider what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE.) Carefully consider what is THE EARTH/ground ON BALANCE. Consider what is a TWO dimensional surface OR SPACE ON BALANCE !! Consider what is perpetual motion, AND consider TIME (AND time dilation) ON BALANCE. Consider what is THE EYE ON BALANCE. Notice what is the associated black “space” AND the dome AS WELL. NOW, carefully consider WHAT IS THE SUN (ON BALANCE); as TIME is NECESSARILY (AND CLEARLY) possible/potential AND actual (ON/IN BALANCE). CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites ON BALANCE; as the stars AND PLANETS are POINTS in the night sky (ON BALANCE). Consider TIME (AND time dilation) ON BALANCE. E=mc2 is taken directly from F=ma. Indeed, the ultimate mathematical unification (AND UNDERSTANDING) of physics/physical experience combines, BALANCES, AND INCLUDES opposites; as ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); as this CLEARLY explains F=ma AND E=mc2. AGAIN, consider what is TIME (AND time dilation) ON BALANCE !! Again, carefully consider WHAT IS THE MAN who IS standing on WHAT IS THE EARTH/ground ON BALANCE !! BALANCED inertia/INERTIAL RESISTANCE is fundamental (ON BALANCE). By Frank DiMeglio

You started your sentence with the word "dude". ('.')

Khalili deserves more recognition than Neil deGrasse Tyson

Pete Mchardy... you don't believe in punctuation obviously.

It was originally on the BBC irrc

Jim al-Khalili made some brilliant docs for the BBC. Those written and directed by Nick Stacey are the best. Viz. Everything and Nothing, Order and Disorder.

Scott McClure McClure I find the transcript useful for times such as this. This can be accessed via the horizontal ellipsis (the three dots) menu at the bottom right of the screen.

I thought because this stuff was pirated. But looked at their channel and they claim to have licenses for all this stuff. So kind of odd they have tampered with the audio. Me thinks they lie, and that they be pirates arrr ye matey! LOL!

Giggety giggety giggety

The question IS the answer.

It's not a question. Scientists were able to equate the energy reqd for different tasks. For instance, they figured the energy required to heat water by 1 degree Celsius is the same energy required to raise raise a certain weight

Mark Hewitt what ads. I didn’t see any to complain about.

Especially since we've got already fission so well refined... and Gen-IV reactors are right around the corner, its going to be a renissance for reactor technology

even fusion does not prevent a fall to entropy, it just takes if form a more abundant source.

@If you can't melt sand - how do you make glass? maybe you should stop with just asking the whys. When you keep asking too many questions to the point you dont put an effort to read the answers it doesnt bring you closer to uncovering anything. Asking the why question for the sake of asking the why question is a behaviour most grow out off by the time one turns 6

The internet is a cringe parody

The only “scientist” I remember being mentioned in school…. Was Thomas Edison…. And I have a hard time counting him as a scientist… Unless you want to count “marketing” and “the study of patent law” as sciences.

This is real flix

Ummm. . . better than Netflix because it's infinitely more entertaining to the mind than a whole bunch of poorly written, made up crap. Just. . you know. . IMHO

The question should be: Why do people prefer watching Netflix to this?

Because you are a good human being, we are the people who define the world.

Had Netflix for a month and cancelled it yesterday.

Movement is energy

ability to do work. Anything that has energy has the ability to do work and work is essentially the transfer of energy. Each time work is done, the entropy of that system increases irreversibly.

how to learn English friend

I read it as Mr. Stark. Oops.

I feel you bro. TBH I find it amazing that more people don't think about stuff like this. I don't think we're the weird ones.

We are just too “busy” surviving under this contrived bs economy to be able to concentrate on the greater expanse. Even so-called higher post secondary university education is aimed towards the needs to survive under the edict of “market needs” instead of genuine People needs. So-called higher education is not for self edification but really glorified pseudo trade education, but it doesn’t even fulfill that.

@@TheRoland444 it's all capitalism's fault.

I too feel you bro, everyone else don't care about this

@Benaiah Ahmadinejad Muslim lesbians eh? Thats rare to find. Take my moneu

I thought it’s been said gravity isn’t a force though? 🤔

@@TaPharoahTrue that. even entropy is not a force. Both entropy and gravity are a property of matter...any matter.

It takes energy to create order. A metal bar was extracted from randomly spread ores, purified, and shaped into the bar. The heated bar, as explained in the video, was heated with energy. Left alone this order of heat dissipates and radiates into the cold, less ordered surroundings until an energy balance is reach, i.e. body the bar and the surroundings are at the same energy state. The bar's heat order falls away. Also, over much longer time frames, the environment will pull it apart through corrosion and weathering until it returns to its dusty ore-like starting point.

Lovely explanation

Well put. I have always had exactly the same opinion.

Brilliant explanation , congrats!

Well said. Order and disorder is a human construct.

the motion itself is a disorder, the motion of atoms is a disorder, like gas molecules when they are in slow motion, they are cooler, when they gain more energy, they gain more speed, they become hotter... this is the flow from order to disorder

What adverts? Install uBlock or any adblocker if using a PC, install SmartTube if using a smart TV or install RU-vid Vanced apk if using a mobile device. Does that help?

@@Joe254KE Eh....I'm not big into ad blocking. It's not ethical. You can argue that a lot of ads aren't ethical but I don't think that releases us as consumers to be unethical. That said, I do use Privacy Badger which blocks the more questionable ad networks and practices. I'm OK with ads, to a point. Showing an ad every six minutes, whether the presentation is made for it or not, is past the limit for me. I'll just find this video elsewhere or not at all.

Get premium.

@HylanderSB - Not ethical? Many channels on RU-vid exist JUST to make money out of you! This video doesn't belong to the people who posted it, It was made for television, and probably pirated from there! WHO is being unethical?

@Wren Linnet - 'Spark' had nothing to do with the making of this content. This is a BBC television program - and the BBC is a non-profit organisation paid for by the British public - the BBC TV licence tax payers. You're being duped.

@Southeastern777 - We are talking about energy here, not about energy consumption. Please stay on topic.

We get it by going to disorder?? sounds like a scam to me

@vladimir putin is andrei panin jfk is jimmy carter "Energy" not "Earth" is the topic here.

@Allah is Satan(Saturn); Mahomet=Baphomet You forgot one thing: you're a hoax.

And there is nothing but empty space between each of the particles (Electrons) that make up atoms and between each atom. 99% of everything is empty space

@@stephenhunter70 yes and do photons have energy, nope they seem to defy the laws of physiccs

@@stephenhunter70 well, one could observe that even that empty space is just a perfect equilibrium of "nothing worth showing". basically, the matter is the change in this equilibrium after some timeless and extraneous interaction disturbs the surface of the spacetime like a rock would disturb a calm lake. what we perceive as matter is nothing more than the angle of the oscillating surface of the emerging waves, practically sudden and complex anomalies in an otherwise smooth spacetime. an entropy is when the ripple amplitudes progressively calm with the increase of their curvature. @1littlelee no they don't. they seem to defy it, but no, photons do not travel at exactly 1c. nothing observable ever does.

Okay, but what is energy? This is definitely a common thing to say, that a lot of people will just go along with without thinking too much further. In a way, it's kind of a generic thing to say, so what is energy then? (hint: energy is not everything, and the next episode is about it)

@@ericgraham8150 energy is everything, that's what it is, lol. No energy = nothing exists...
