Best TH-cam video on The Vacuum of Space. You state obscure facts in all your vids, that no one else dares to mention. After viewing others and getting my "feet wet", I ALWAYS learn more in depth knowledge for your channel.
Oh, i'm surprised to watch a video of "Scienceclic" in english, i already watched all your videos in french! Good continuation for transmit your scientists-knowledge in english!
Absolutely incredible content. The attention to detail is utterly awesome. When you showed the matter getting "syringed" out of the container, the animation is so incredibly intuitive, and instructive. We can see how the volume has suddenly increased, but since no new matter is introduced, the pressure is dropped, thereby reducing the concentration of atoms inside the container (e.g... the fundamental principle of how pumps work!). Please keep making more!
understanding complex subjects of physics is necessary and not easy. Your videos are very clear and simple! Your efforts in preparing your videos deserve gratitude and recognition !! Thank you very much. Already subscribed, I like and I share.
I have just discovered this channel and am so glad I did; the explanations are exceptionally clear and the animations are just superb. I appreciate the thought, time and energy that is so obviously put into the making of these videos. This channel is a significant educational resource that we all benefit from - thank you. There are a couple of philosophical issues around this particular episode worth considering. One often hears the claim that virtual particles may come into existence (however briefly) out of 'nothing' and disappear back into nothing. The vacuum is not nothing, it is most definitely a something, and a pregnant something at that. It has an energy content and other properties such that it is the kind of thing that may give rise to particular kinds of virtual particles, themselves with particular kinds of properties - a buzzing sea of fluctuation, motion, energy and action. Even spacetime is arguable a something, which has specific properties in that it may be warped or distorted, that light has its particular velocity in relation to it, that it bears a certain relation to energy and mass etc... Sometimes the claim that matter and anti matter and even the universe itself can arise out of 'nothing' is posed as a way of dismissing the question 'why is there something rather than nothing?' But this is a very loose way of talking. If the universe or any of its parts ever did just 'pop into existence', it popped into existence out of a deeper ground of being and becoming; out of a something, however mysterious that may be.
I agree all your comment and the video is really very well made with in depth knowledge. I am more interested in the vacuum catastrophe, we need to find the solution just like plank found for ultraviolet catastrophe!
All videos on this channel are great, accurate and very informative, but depiction of atom and it's electrons you've created is the best I've seen on internet. Not only scientific but also, so beautiful. Thank you
i don't have links to hand which is a bit annoying, but there are "as good if not bette" depictions of atoms as we currently understand them, even tables of fields, i'll have a quick search.
4:08 You can still define it in terms of an equilibrium. The temperature of a location is the temperature at which a black body would radiate as much radiation as it absorbs. This definition of temperature allows us to assign a value for temperature even for empty space, that turns out to be around 2.7 Kelvin (if you're in the middle of nowhere). Edit: actually, rethinking about it, the temperature i described will probably not be the same as the CMB temperature, as a younger, naïve me thought.
but space has an emissivity of zero, it neither absorbs nor emits. And it's full of 1.7K CM-neutrinos (actual matter), and maybe cold dark matter. So in lieu of a 3 hour video: space has no temperature (unless it is the space that is an event horizon...make it a 5 hour video).
I believe that anti gravity relies on a perfect vacuum and absolute zero temps. Gravity can only act on an existing body and the less heat and object emits the slower it becomes. The laws of physics literally begins to reverse itself the closer one gets to zero conditions. I like to imagine a perfect vacuum acting like bubbles in a pool. You remove an area of space and you begin to float upwards.
Those pairs of virtual particles created are also entangled (corelated) and that creates the space(time). Quantum fluctuations constantly generate new space (statistically equally everywhere) and that's why Universe expansion is accelerating.
4:37 paraphrasing: "the nucleus of the atom is 100,000 times smaller than the atom, yet makes up 99.9% of its mass. The rest of the atom is empty space." For a moment there I thought the nucleus could represent planet earth having 99.9% of the mass of living things and the remaining empty space in the atom could represent the entire known universe. An intelligent, grand design.

Perhaps that number is so much higher due to us not understanding the constraints that may be placed on quantum field theory if successfully merged with General Relativity. I wonder if some other scalar field may play a role in slowing down this speed in a similar way to how the Higg's field provides mass to certain particles, making them travel in space slower than the speed of light. Perhaps there may be something other than just the Graviton at play here, but rather something even more fundamental than the fields we know of, related to the very ability for quantum fields to be randomly disturbed as a whole.
It is by will alone I set my mind in motion. It is by the juice of Sapho that thoughts acquire speed, the lips acquire stains, the stains become a warning. It is by will alone I set my mind in motion.
I think that the phenomenon of virtual particles could be a consequence of the existence of matter within the universe instead of being a property of "space" if expressed within a more fundamental theory than nowerdays qf-theories. Just as Mach argued if inertial forces within rotating frames could vanish, when removing the masses of the universe, one could also question if the properties of what we call "vacuum" in general keep the same if one does so. I could imagine that all those mass relations and parameters of nowerdays standard model are not just good given numbers but are subtile anomalies occuring from our lack of understanding about the connection between fundamental particle physics and cosmology.
After watching and understanding this, how can one deny that the universe wasn't created by God. There's no way all this happened by accident. It's perfection.
@@shrimpflea According to the Bible, God always was. And always will be. He's out of the realm of time as we know it here on Earth. He has no beginning and no end.

Can someone who is good at physics explain this to me: So the interstellar medium is "empty", meaning you couldn't propagate any sound waves or heat through massive particles. But light can travel through, which for me implies there is some sort of medium it is travelling through. What is this light medium?
Amazing, so when they say solar radiation from the sun causes the earth's temps to rise, what is exactly traveling through the vacuum to say reach this planet and warm it up when we are traveling not only around the sun and rolling side to side but moving and then all in a galaxy that's in interstellar space, it's mind boggling!? Thanks!
Since your sense of *cold and hot* depend on heat getting extracted from you or vis versa empty space would feel cold. You would get torn appart. Diffusion would cause you to lose heat (and everything else). So in case you wouldnt die instantaneously, it would feel cold.
Could the “vacuum disaster” number be a one that can be broken down into a base number at each point of time as it moves through the space/continuums? I wonder if it’s divisible by 9, or how Tesla may have understood this conundrum
How do we know there's 1 particle in vacuum between galaxies, how was it measured? How did we come to this conclusion? If I was to place sealed container of air close to pluto how exactly will the air particles be measured in that container?
@@ScienceClicEN ohh, didn't expect you to answer yourself. And certainly not that fast, thank you! Wow I see, I thought it was with some other software. You must be pretty skilled and/or put a huge effort in them. Appreciate it and also all other aspects of your amazing videos!
can you explain how light doesn't collapse when projected on a wall for example (and we can still see the uncertainity)? If the collapse it's not time dependent, why do we still see wave patterns 🤔
If a atom or matter is 99,9% space, then a black hole is rather a space then a mass conserver. So its not mass that fall's to each other but its space, that wants to cluster. What happens to the space between the electron and the atom at almost the light speed of the electron, going arround it? You get a inward wave going in the direction of the core and a outward wave, is there a differance, like with the inward and outward track of a racetrack. I mean if the nucleas bend space a bit, and the electron does, then the space between them gets stretched more, then the space outside the electron. So this 99,9% of space is less dence, then all the space arround it. Does this more stretched space then let the electron fall a bit deeper to the core for instance?
Sean Carroll says the whole atoms are made of empty space thing is wrong. Ill have to figure out how to reconcile the various descriptions in context to one another.
I think what he could mean by that is that the electrons in an atom are spread throughout space, and therefore the atom is not really empty, it is filled with this "electron probability presence"
If the black holes convert virtual particles into real particles due to its immense gravity, why doesn’t that real particle fall back into the black hole? And, he was referring to Hawkins radiation correct?
galaxies are moving apart because of anti gravity. The absence of matter negates gravity...Matter creates gravity, the absence of matter creates anti gravity. Matter creates energy, so too does a vacuum creating negative energy. I like to thing of it like a scale of 10 to -10. 10 being matter and -10 being it's vacuum counter part. Lol I aint no scientist I just like speculating.
i recently have been considering if the empty holes in our universe i.e. "the large voids" have a space/time that is "faster" than ours. with 0 atoms in a cubic meter what does this mean for time? the idea that "virtual particles" appear then disappear inside a solo vacuum should not be an explanation for where virtual particles go. we really do not know what happens there in the voids and as you mentioned it might have something to do with dark matter and the expansion of the universe.
Totally depends on what youre trying to say. If you only look at 1m^3 of pure vacuum, time wouldnt slow down or speed up. Why are you expecting that to happen? Because of gravity?
To most people the idea that we live in a simulated universe is absurd. Then if you read about the double split experiment and quantum mechanics with particles appering out of nowhere I atleast go.... aight...., our universe does seem a bit simulated after all 😅
Could virtual particles just be accelerated in time, and become more visible in a vacuum. Also having mass but at such speeds temporally that the pressure they exert is low, it could be where the missing matter and dark energy is. It would maybe also mean the big bang is somehow still sending them, which is a bit to much of temporal mind bender, more so if considered at the relative temporal speed they exist at there could potentially be formations of greater bodies because at their speed they could actually behave as a solid. I guess the question is how they enter gravity wells if any of this has any kind of truth. It is entirely speculation though.
It is not really correct to call atoms "mostly empty space" concidering that the size of an atom is roughly defined by the space that its electrons take up. It would be more accurate to say that we are mostly made of electrons by volume.
but electron are point particles, and it's their electric fields, not the electrons, that do the work. On the other hand, white dwarfs are made of electrons, by volume (hence: degenerate pressure). But it doesn't matter: the "mostly empty space" is a useless classical concept anyway.
if i was a billionaire, id be like "yo A.R..... here's 100million, produces the worlds best teaching videos on anything science you want". AI will sing your praise long after humanity has turned to dust
I’ve often wondered what would happen if you were exposed to Space , would you boil because of the pressure difference before suffering from freezing ? Or something different seeing as even though it’s so cold , around minus 260 degrees , there wouldn’t be a lot of molecules to transfer energy(heat) away from the body , would the lack of pressure kill you or the temperature or both ? , does anyone know ? . Thanks . R .
yes. but no. The original ether was a stationary medium (in a Galilean sense). The quantum fields could be considered ether, but they are we behaved under Lorentz transformation (e.g.: you cannot move relative to the electromagentic field, it looks the same no matter how you move [w/o acceleration]), so they're not The ether.
5:20 Maybe I'm just being pedantic about the animation, but don't virtual particles occur in matter/antimatter pairs? I only know this thanks to Stephen Hawkning and the concept of Hawking Radiation btw. So it's possible I could be wrong and the matter/antimatter pairs only happen with photons. But that doesn't sit right with me. Please elaborate if I'm mistaken.
I may be wrong on this (since i’m not a physicist), but from what I’ve researched; The “matter/antimatter pairs spawning into existence and annihilating each other” is a very simplified explanation of quantum virtual particles. It’s better if it’s expressed in waves that has constant destructive interferences.
Haven't watch video yet. But I would assume that a true vacuum would not even contain spacetime fabric. So basically its outside of the universe or existed only before the universe?

I try to combine the cosmological constant and the schrodinger solution on the planck scale.
I used planck units.
At the end I went back to SI units to compare with the measured vacuum energy density (0.63 10^-9 J/m^3.)
Combine:
1) Einstein, cosmological constant
2) Schrödinger solution
3) Planck units
Result:
- vacuum catastrophe solved?
1)Einstein, cosmological constant
Λ = (8π 𝐺 ƐΛ)/(𝑐^4)
Planck units:
G=1
c=1
Λ (6.1871424 10^34)^-2 = (8π ƐΛ [planckEnergy/planckVolume^3]
1.1056 10^-52 (6.1871424 10^34)^-2 = 8π ƐΛ
0.001149 10^-120 = ƐΛ
0.1149 10^-122/ ƐΛ = 1
2)Schrödinger solution, n=1
(ℎbar^2 𝑛^2 𝜋^2) / (2𝑚𝐿^2) = E
Planck units
hbar=1
n=1
m= mplanck =1
L= Lplanck=1
0.5 𝜋^2= E
1= E/0.5 𝜋^2
3)Einstein, Cosmological Constant = Schrödinger solution
0.1149 10^-122/ ƐΛ = 1 = E/0.5 𝜋^2
0.1149 10^-122 0.5 𝜋^2= ƐΛ Eplanck
Eplanck =1
0.1149 10^-122 0.5 𝜋^2= ƐΛ
0.567 10^-122 = ƐΛ [planckEnergy/planckVolume^3]
0.567 10^-122 1.9561 10^9 /(1.61625502 10^-35)^3= ƐΛ [J/m^3]
ƐΛ = 2.627 10^-9 J/m^3.

To most people the idea that we live in a simulated universe is absurd.
Then if you read about the double split experiment and quantum mechanics with particles appering out of nowhere I atleast go.... aight...., our universe does seem a bit simulated after all 😅
Is an empty planc length cube completely empty then?
4:19 Gravitational waves can also travel in empty space….
Could virtual particles just be accelerated in time, and become more visible in a vacuum. Also having mass but at such speeds temporally that the pressure they exert is low, it could be where the missing matter and dark energy is. It would maybe also mean the big bang is somehow still sending them, which is a bit to much of temporal mind bender, more so if considered at the relative temporal speed they exist at there could potentially be formations of greater bodies because at their speed they could actually behave as a solid. I guess the question is how they enter gravity wells if any of this has any kind of truth. It is entirely speculation though.
Bravo ! 👏 👏 👏 👏
It is not really correct to call atoms "mostly empty space" concidering that the size of an atom is roughly defined by the space that its electrons take up. It would be more accurate to say that we are mostly made of electrons by volume.
but electron are point particles, and it's their electric fields, not the electrons, that do the work. On the other hand, white dwarfs are made of electrons, by volume (hence: degenerate pressure). But it doesn't matter: the "mostly empty space" is a useless classical concept anyway.
At what speed do virtual particles move in space time?
if i was a billionaire, id be like "yo A.R..... here's 100million, produces the worlds best teaching videos on anything science you want". AI will sing your praise long after humanity has turned to dust
I’ve often wondered what would happen if you were exposed to Space , would you boil because of the pressure difference before suffering from freezing ? Or something different seeing as even though it’s so cold , around minus 260 degrees , there wouldn’t be a lot of molecules to transfer energy(heat) away from the body , would the lack of pressure kill you or the temperature or both ? , does anyone know ? .
Thanks . R .
@ 5:00 Might this be seen as a quantification of the unidentified Ether?
yes. but no. The original ether was a stationary medium (in a Galilean sense). The quantum fields could be considered ether, but they are we behaved under Lorentz transformation (e.g.: you cannot move relative to the electromagentic field, it looks the same no matter how you move [w/o acceleration]), so they're not The ether.
4:17 “Electromagnetic waves are the ONLY waves that can propagate through a vacuum or empty space”?!?! What happened to gravitational waves ‽
5:20 Maybe I'm just being pedantic about the animation, but don't virtual particles occur in matter/antimatter pairs? I only know this thanks to Stephen Hawkning and the concept of Hawking Radiation btw. So it's possible I could be wrong and the matter/antimatter pairs only happen with photons. But that doesn't sit right with me. Please elaborate if I'm mistaken.
I may be wrong on this (since i’m not a physicist), but from what I’ve researched; The “matter/antimatter pairs spawning into existence and annihilating each other” is a very simplified explanation of quantum virtual particles. It’s better if it’s expressed in waves that has constant destructive interferences.
Isn’t concept of virtual particles somewhat similar to luminiferous ether ?
How can we know virtual particles exist?
The cassimir effect
Casimir*
The Lamb Shift
And no short vid about vacuum catastrophy?
Haven't watch video yet. But I would assume that a true vacuum would not even contain spacetime fabric. So basically its outside of the universe or existed only before the universe?
The true vacuum you are talking about is equal to no-existance. If something exist isnt empty nor nothing.
I think the key word is "existance".
@@roner61 Yeah my use of "existed" there was a bad choice of wording. But yeah I get what you mean.
Never thought someone would be able to make literally nothing interesting.
Well, technically virtual particles are a *product of vacuum fluctuations, not entirely the same thing as.
Ta créer une chaine anglaise.Mais voir ta chaine en anglais parait bizarre.
PLANETE MARC true c’est la même vidéo
virtual particles are basicly just noise of quantum fields.
