Gaaaaaahdang that’s a fun fact

In the vaccum of space is what you mean, sounds moves at the speed of sound in air, because it's sound after all lol

What is meant by „the sound“, is the sound of the sun. And since space doesn’t conduct sound waves because of the lack of particles, the assumption is made that it would be possible. Therefore you would need to choose a medium. Water could have also been chosen, sondwaves now travel four times faster than in air. The time would shrink to only 3,5 years. But the more familiar medium is air, thats why the formulation of the statement may have confused you.

@@abdou.the.heretic Vaccum isn't a medium in which soundwaves can travel..

Having played in marching band and intuitively knowing how long it takes for sound to get from one place to another, that makes the Sun actually sound reasonably close to us, which in a sense it is.

I go back a few years. This sound is quite similar to the cabinet noise of a 9-speed standard tank truck traveling at 130-140 kph with moderate load and no requirement of intermediate gears.

​@@richardkammerer2814Thank you for that extremely specific example

@@richardkammerer2814 oh that's a really concrete comparison! Nice!

The moment I heard these sounds (specially the whistle from the Sun's magnetic field) I immediately thought it would be a good idea for them to be used in some form of movie or something, it would make for some really good sfx/soundtrack if edited properly!

Yeah, not using any of this if I ever get a chance to use radio interference noises to depict cosmic radiation in sci-fi exterior shots. Unless the characters fly too close to the sun. *Then* I'd use the Whistler waves.

True but then our ears aren't scientific instruments.

sound pressure isn't same as sound volume

of course this varies by frequency. In the most sensitive area from about 2k to 4k you need a lot less dB for a perceived change. Right at 3k a 3dB change is all thats needed. But down low at 100-300hz you need a lot more gain to perceive a noticeable difference. Fletcher-Munsson curve and whatnot.

What??!

Nuts

For real, Parker is an amazing accomplishment in heat management. This is hard to do in space!

I'd like to add thanks that the incredible man the Parker Solar Probe is named for was still living to see his namesake's launch. Now they both fly free.

It was quite simple to design I imagine. They just had to always make sure to approach the sun during the nighttime.

@@spjspj4 a person who thinks all the time has nothing to think about except thoughts

Only because the logarithmic scale is base 10 doesnt mean a change of 10 dB results in a sound being 10 times as loud, the sound "only" doubles in volume for a change of 10 dB

*EXCUSE ME* !!! On the video at 2:30 it says "3.85 x 10^26 W/s" What the *FOOOWKKKK????????? ???? I know what a WATT is but I have NEVER heard of a "W/s" The narrator says "Watts every second" NO. There is no such unit. There is a Joule and there is a Joule per second but there is *NO SUCH THING* as a "Watt per second" or a "Watt every second". The narrator even says "3.85 x 10^26 Watts every second" No No No, this is NOT a unit. You have a choice: either Joules per second or Watts, but NOT "Watts every second".

@@simonmultiverse6349the whole thing is silly. They are taking radio waves and lowering them in frequency until they reach the sound wave level, there is zero sound coming from the sun. All of these sounds of the planets are not sounds at all, just radio and microwaves lowered in frequency. Any form of energy could be lowered to sound waves, a lightbulb, a microwave oven, and even the transmission from a radio antenna are lowered so we can hear it. They never were sound waves in the first place.

Yes, 'fascinating', and all that... but unless such information leads to something that is practically useful to us (like finally cracking the tech to make nuclear fussion reactors, or some such) then it's in essense nothing more than mere entertainment at this point.

@@sunnyjim1355 There are times that I still feel the need for childlike wonder, especially in space stuff. In the meantime we can exploit every single asteroid and crack all the secrets of physics but I still need the wonder from time to time.

@@simonmultiverse6349have you ever heard of a kilowatt hour?

Just saw that and searched the comments. Now that this minor error is pointed out and corrected, we can resume watching this cool video.

I learnt the difference between energy and power when I was about ten years old. Spent my life watching almost everyone get it wrong.

Hahaha, me too.@@mandjaco

@@mandjaco It got corrected?

@@tonyho1959 I mean, here in the comments.

Auroras sound a lot more interesting, ever got those with your hardware?

@@DanSlotea Yes I have. You are correct. basically a weaker version of what I was talking about. Aurora effect and meteor showers. Both have interesting effects on how radio waves propagate on the planet. A massive corona ejection on the other hand, nearly wipes out the ability for radio waves to propagate, on many bands and all you get on the radio is the noise of the solar flare itself.

Watt hours are a thing

Agreed but again they are not a unit of power. Watt-hours is an amount of energy. A Watt-hour is 3600 Joules. @@RoboticNerd

watt per second is how fast a power source "warming up" or dying

@@sakesaurusig then it would be not to dissimilar form metres/s/s, which is acceleration, so the full term for watts per second would be joules/s/s, which would be the amount of joules per second that you are gaining in a second

This point is so nerdy, I love it!!!

Yup, twice the perceived volume, 10 times the energy.

@@LiamE69Had to think hard about this for a while. Yes 10dB is indeed ten times the incident power level. The concept of doubling or ten times the loudness is the one that confused me. Going from 10dB to 20dB requires ten times the sound power, so does going from 100dB to 110dB. They both cause the same subjective increase in loudness. It makes no sense dividing 20 by 10 and saying it is a doubling. Going from 110 by 100 gives a 1.1 ratio but is the same subjective increase. A doubling of power adds 3dB to the perceived loudness. Ten times the power adds 10dB. A hundred times adds 20dB.

Saturn's sound remains screeching and haunting

​@@summerbrooks9922Pluto sounds like an ambient video game OST

Thank you for the correction! I did think that seemed low but I didn't go back and double-check 😫

@@astrumspace What is the music used at 5:45 and 11:30? Is it generic youtube library music or a specific artist? It sounds nice and relaxing. Keep up the good work.

Wow a huge difference of perspective at this speed. This jump in speed is astonishing, is there any research suggesting the mass is conserved and it's a pure force gain? Possibly due to it reaching a certain free point where the net force just instantly triples

@cocopatty WHICH PAPERS? Where? Can you provide a source citation? I want to see that.

I think it's a combination of that and the intense magnetic fields spewing out charged particles... That's what I've heard.. it's probably a combination of everything

no matter how dense the corona is... its far less dense than the sun. So that wouldnt explain why the corona is hotter than the sun.

Ikuona

@@summerbrooks9922 yes. How Can I help you?

Ew

@@AlecsNeo ew? Yes, I, and many others know that in most, if not nearly all cases Metric is better; but many of our brains still work best on Imperial as we were "trained" in it from a young age and throughout our lives, it is very useful to us to have both. You saying a mere "ew" is an issue on *your* end, not ours.

Hello @Simple_But_Expensive, I appreciate your insightful comment. As an astrophysicist at NASA's Jet Propulsion Laboratory with a specialization in celestial bodies, I've spent a significant portion of my career studying phenomena related to our Sun. Your understanding of the Sun's "hum" from your background as a power plant technician is fascinating. In the field of astrophysics, we refer to this "hum" as oscillations within the Sun's body, a subject studied under helioseismology. These oscillations are the result of turbulent convection of the Sun's plasma in its outer layers. While it might seem intuitive that a larger object like the Sun would oscillate at a lower frequency, the actual situation is a bit more complex. The Sun's oscillations are driven by a combination of factors, including its immense size, the intense heat and pressure within, and the dynamics of plasma and nuclear fusion. This results in a broad spectrum of oscillation frequencies, some of which fall in the millihertz range-higher than a 60 cycle (or 60 hertz) hum. Regarding the uniformity of the Sun's "hum," it's true that the Sun's oscillations vary across its surface and depth. However, from our vantage point on Earth, these variations are difficult to discern due to the vast distance. As you correctly surmised, a closer examination would provide a more nuanced understanding of these oscillations. It's always exciting when we can apply our everyday experiences and knowledge to understanding celestial phenomena. The Sun, as familiar as it is to us, is still a subject of ongoing research and continues to reveal its secrets. Your curiosity and eagerness to understand these phenomena by applying your professional knowledge are commendable.

Thank you both for explaining this in such concise detail.

@@positivefandom9066 Yes, same. There is something calming (I have OCPD) about seeing someone know (much) more than I and to not be able to find anything that seems fallacious or biased, or parroting, but people who understands both the broad concept of their field and the small details (which makes the whole). In "English": I enjoy people who know what they're talking about, or a discussion between specialists (it can bring insights and is interesting and can learn a lot) *TLDR;* Ahhh sweet brain stimuli! My neurons are happy:)

Unfortunately, the writing style of the second commenter appears to be very much in line with AI-generated text. Unfortunately, that response likely wasn't real

@@ricdeh1701 Sure, but so is your inhuman overuse of 'Unfortunately'. Currently 100% of your sentences begin with unfortunately, something most humans (a positive, and fortunate being) would be unlikely to do?

The sun remains a condensed matter entity and liquid metallic hydrogen. So you seem to be spot on with your idea of solids electromagnetically active.

That would demonstrate a true miracle.

So the Buddhists had it right all along. So much for the Abrahamic religions.

Then, we must be kin to the stars as different substrates of electromagnetic energy.

@@summerbrooks9922 hell yeah we are! I'm a star! You're a star! We're all stars!

There is a limit to how strong a wave of sound can be unfortunately, which means supernova aren’t actually all that loud (_in terms of sound ofcourse_) However there is another problem.. because the waves supernova generate are so high in frequency and so high in energy that they can’t be heard as sound waves, however if these waves are stretched from space expanding then I truly wonder how a high energy wave would sound like once it is stretched enough to become a sound wave…but it might not be “audible” per say as it might break the sound wave limit I was talking about, it might require ultra high pressure gases to raise the limit just enough for it to be audible but the pressures I’m talking about are probably impossible for a gas to exist at anyways. All of this ofcourse depends on the imaginary physics that make sound waves travel through space

Or super massive cluster and the black hole inside with the star fighting to escape

Classical physics remains the essence of how our universe actually works. Guard it with fierceness.

@@summerbrooks9922 well, may e at classical scales. Quantum mechanics is pretty different and manifests on only a few ways at our macro scale. Astronomers still working out the curvature of the universe and the like. I am curious and love to learn more. As an engineer I am keenly aware of how knowledge is literally power

I was wondering that, too. I think these are actually useful questions in terms of making mysterious things more comprehensible and engaging.

Soot.

The sun is not a ball of plasma. It is a drop of condensed matter composed of a lattice, hexagonal planar, which chemically supports the liquid metallic hydrogen into a helium molecular into the sun's atmosphere in the photosphere. 15:09

He's a real creator :D he's excellent. Many of those other space videos out there are AI generated click baits but Astrum and SEA are real, and they're my favorite space channels!

Thank you!

Pierre Marie Robitaille is the new multidisciplinary Newton of our time. His influence encouraged this European scientist to compose a new and vibrant book, "The Liquid Sun." It demonstrates the best ideas of the sun as a condensed matter entity composed of Liquid metallic hydrogen. Proof of which knocks black holes out of the fairy tale storybook. And it kicks dark matter into oblivion. Where it belongs. Donald E Scott has buttressed this view with convincing g evidence.

How humble you remain! So fine.

Hate to break it to you buddy but we don't exist. Frederick is just dreaming again. We gotta play along until he wakes up. Didn't anyone tell you?

Statistically, everything is possible at 100% certainty over infinite time and infinite space. So us existing is not a big deal. We are a certainty just waiting to happen sooner or later. It just looks magical to us because our lifespan is infinitesimally small compared to the scale of the universe.

We’re also made of them. Stars are our ancestors. Or we are their ghosts. Not sure which I prefer but they’re both elementally true.
