The society we live in, where we really have to ask if the ISS is underwater... You can literally see it in the sky at the right time.

For heaven's sake, don't mention submarines. Those vessels are filmed in space with a blue screen showing deep water. Everyone knows you can't dive deeper than the flat earth's swimming pools!

14:51 "Okay guys, brainstorming time! How do we hide our advanced underwater breathing technology from the public?" "...invent fake space travel...?" "Let's do it!"

As someone with underwater photography experience, I freaking WISH we could get such lighting underwater lol. Filming these allegedly "fake" ISS footage clips would be impossible to do in such a manner underwater, just like you explained, but I can also confirm from personal experience. The way the water affects the light and colours is exactly the reason why I main macrophotography instead. Seriously, these deniers are ridiculous

Not a shocker that Pokie didn't apologize ... Rule#1: Never admit you are wrong, just move the goalposts.

It's crazy the lenghts flat earthers and space deniers will go to delude themselves into believing they are the smartest people on the planet.

I bet most people making claims about where and how the ISS is faked and filmed have never worked on a film production before. It would take hundreds of people to pull this off. Prop makers, catering, production assistants, costuming, continuity control, camera department, grip department, consulting experts, and the list goes on. The more people involved the less integrity the operation has. I'm not saying it's impossible, but I am saying it would be insane to keep this a secret going for 20 plus years. Also, The soft hatch, if under water, would simply cave in over the airlock because water has mass, and therefore, apparent weight in earth's gravitational field. I really don't know what else needs to be said about that.

It amazes me that anyone can sit and watch someone throughly explain how something is legitimately real and impossible to fake, and they’ll still cry about it! Nicely job, Dave (and Rusty!). Always fantastic to see you tear down the flerfs’ false perceptions.

You missed one extra that can't be debunked... the refraction of light between the helmet glass and the water/space. In water, the light is refracted to make the astronaut's face look smaller - in space, the refraction to the vacuum is much less, so the face looks 'normal'. You can't get around the 'tiny face' seen in water training. 😅

Local government public meetings in the US can be unbelievably unhinged. Not just at the county level, but municipal government and school boards too.

My friend was so convinced of flat earth, he said he was going to Antartica to find the edge. He came around eventually

I'd love to see a flerf show a "soft hatch" underwater actually behave like the clips. But of course they cant, since neither a hard or soft material would work that way in water.

I remember a Mythbusters episode where they focused on NASA conspiracy theories. For the Moonwalks (1/6 G), they actually tried to recreate it with wire harnesses and underwater footage. As expected, while they could fake a few details of the original footage, they couldn't get all of the details to match, and there were idiosyncrasies in the recreation that gave away when water or wires were used.

So...People who can easily track its movement in space and even see it with the naked eye from time to time, think its underwater? Do they think WE are underwater?

Thank you Dave for what you do. My husband recently came face to face with a real life flat earther and her posse of conspiracy theory nuts. Thanks to your videos I was prepared and able to easily set his mind at ease. Thank you for your patience and thorough answers.

LEO calling himself a realist when he doesn’t have a clue how physics works is hilarious

Well done Dave. Totally destroyed Leo. I don’t care what he wants to be called. He is still wrong.

The most hilarious thing about it; why would NASA put all this effort and money into faking it..... just to forget to edit out a bubble lmao

The ISS is not in a pool, it's actually offshore. I hooked it once while fishing. Spent hours reeling it up. NASA was pissed.

Great breakdown, Dave! 🙂A while back I did a deep dive (pun intended) into the mythical "Space Bubbles." *Characteristics of “Space Bubbles:”* 1. They move in straight-line trajectories, with no turbulence. 2. They move in different directions from each other. 3. They can have dramatically different velocities from each other, independent of size. 4. Some slow-moving ones can be seen to flash with a regular rhythm. 5. They travel alone. *Characteristics of Scuba Bubbles:* 1. They move upwards in the same direction, but with turbulent trajectories. 2. Small bubbles all have pretty much the same velocity, but it is dependent on bubble size (see Stokes’ Law, Newtonian viscosity). 3. They have a morphing shape as they ascend, and larger bubbles will break apart (especially as they get larger as they ascend to lower pressures). 4. They travel in packs.

"How's that debunking working out now that they are officially being investigated by the senate" has got to be the most idiotic thing I've ever read in my life. Do these people have any idea how unfathomably idiotic the average politician is? They'd investigate a geyser if they thought it dispensed Mountain Dew.

Don't be silly, the ISS is in the middle of Mississippi. Twice.

now for the real conspiracy: all scuba diving videos are actually in space

Dave I would also point out that the astronauts suits are instantly dry, with any water dripping down, even in a pressurized underwater capsule gravity would pull any remaining water down.

I really wish these people would actually learn about visual effects, and even with all the modern tools and technology how hard it is to do. Just a few views of some of the Corridor Crew videos would show how difficult techniques like rotoscoping are, and its almost certainly not done in real time. I would love them to show a video of someone removing bubbles from a scene in real time now, let alone in the pre-2000's when the ISS was being built

Wow he actually titled the video "sweet and sour propaganda." What a classy guy lol.

I am actually going to argue that building such a structure deep underwater would be possibly even more difficult than launching it to space.

Another point on the blue shift in water is that it will vary depending on distance from the light source to the subject to the camera as the light is being filtered out throughout that distance. Objects with a longer distance here will appear more filtered and it will be impossible to correct the color of every object to it's original colors independently.

Your attention to detail alone is why I watch and enjoy your videos! You manage to put your experience as a professional photographer to new uses and make as amateurs aware of what goes into a good shoot (imagine trying to do an "underwater" scene without being under water - it would be equally hard than faking a spacewalk scene in water).

There’s a girl who constantly tells me the ISS is fake and I’m like “bruh I saw it with my own eyes AND in binoculars that shit ain’t fake” and she go “…but what if it is??”😂

As someone who grew up and lived in Brevard County, FL, my entire life until a few years ago, he is by-far NOT the most weird or insane person we have there. In fact, as far as crazies go he is pretty chill. And, he is more eloquent then many, many people in this godforsaken county.

Another point: underwater the heads in the helmet look much smaller than they are, but they look absolutely normal during EVAs

I'm honestly worried about the flat earth topics being brought up in government meetings and politicians entertaining them. People wonder why I rail on flat earth people so much. Stupidity spreads like a disease. The conspiracy hill is slippery as hell.

I love how you approach these questions from two perspectives: 1) why what we see is what you'd expect with the real IIS, *and* 2) why what they propose (e.g. underwater) doesn't fit with what we see. Honestly I can't believe we're even debating topics like this, but it provides good entertainment and fun thought experiments.

The fact that such an explanation is even necessary, just shows how far we’ve fallen as a species

I’m a diver. And in the past I’ve also taken a lot of photos underwater. One thing you notice is that the underwater world appears different to the surface. There is what I can only describe as a matte finish underwater. Peoples faces especially look matte but everything else has a similar appearance. Also even after a 2 hour dive you still have small bubbles attached to you which are visible and often detach. I would guess not one ISS denier is also a diver of any experience. Possibly because diving takes a level of intelligence.

You missed a big one. Water has a strong index of refraction. Look at the astronauts' faces in the underwater footage. They have shrunken heads underwater but not so in the EVAs.

It amazes me that NASA supposedly has this amazing special effects tech but Hollywood refuses to touch it.

Man, I have that same scope you have in the background, (127?) I've seen the ISS with my own eyes. I find FE's entertaining, but after a bit they just make my head hurt🤣

If simulating zero g is so easy, I'd like to see some flat earthers recreate the effects in their garages and swimming pools. That could be hilarious.

To be honest, at this point it would be easier to completely 100% CGI anything space related than trying to film it under water and then removing how the water interacts with everything.

It's impressive how you keep coming up with points I've never heard before and make them easy to understand. Excellent video once again!

( _warning_ _:_ _Longish_ _post_ ) I have a relative who lives about 150km away from me, and with their help I did a really simple triangulation of the ISS's altitude (as well as a bunch of other satellites, including Terra, Lacrosse 5 and ALOS-2). We actually did the mathematical working out on the basis that the surface between us was flat, since the Earth's curvature is only about 1 degree over that distance. You could even do it, roughly, by scale drawing. We got an altitude for the ISS of 390 km, and a groundspeed of 6 km/ sec. We got similar altitudes and grounds speeds for all the other satellites we did this with. That's far higher, and far faster, than any normal aircraft or balloon - and this kind of measurement isn't that hard to do. I've also been able to track the signals produced by several with a radio kit that cost me about £30. To boot, there are plenty of natural objects staying up in the sky that are, by any method of measurement, far far higher than the altitude of any aircraft - so there's no reason for incredulity that such a thing could be. So, even for a flat-earther who has openly bought into it on the basis of something other than following evidence, like religious belief, there's no room for the outright denial that satellites, in general, are machines up there and doing the things claimed. Yet, time and again, this is exactly what they do, meeting objections like mine with attempts at social-tactic dismissal, accusations of fakery (so... don't believe me, just do the experiment yourself folks), or just silence. To my mind they (those who do react this way, as no group of people are all identical) act in a way that suggests this is more an emotion-driven kickback against the modern view of the world, and - perhaps - the place they (and all people) hold within it.

Do people not realize you can actually see the ISS orbiting the earth with a telescope

the fact that people claim the ISS is fake despite being visible with the naked eye from the ground is actually hilarious

I'd heard of flat earthers, but I didn't know there are people who believe space doesn't exist, or that the ISS is underwater. I'm starting to think that some people fall down some sort of rabbit hole, where logic and reason go away completely, to the point where the more ridiculous the claim, the more plausible it seems to the person.

LEO, "I'm not a flat earther, I just believe the earth is flat and all the evidence that goes against my belief is a conspiracy."

I'm in absolute disbelief that Pokie didn't concede (/s just in case)

LEO is a special kind of person. A demonstrable realist who refuses to look at any evidence with an open mind because it doesn't suit his narrative. Keep up the good work Dave and hopefully one day LEO's brain will melt, not that that would take a lot.

Not only do we know these people have never been to space, but now we know they have never been underwater. Moving underwater is so much effort and astronauts move things around effortlessly and frictionlessly. Don’t know if that last word is a real word.

Honestly those people who don’t think we went to the moon or think that we actually don’t have a space station jeez grow up… Stop acting like a baby and just accept that humans have gone to the moon. Start acting like your age rather than an a literal toddler….

I think flat earthers and space deniers just think water is invisible. I was going to say more on this but then I just felt a great weight of exasperation that this is a topic of debate at all.

I *so* admire your patience, Dave. Cool and collected, delivering blow after blow without any putdowns or sarcasm. Stylish. Nice!

It will never cease to amaze me idiots just can't come to terms with the fact there are people a trillion times smarter than them who got us into space.

Here is a good quote that my dad told me once… “Arguing with a smart person is hard, but arguing with a stupid person is harder” Most people don’t care to learn the truth if they are chin deep in their own misconceptions and lies.

Debunking Flerfs, argument by argument 👍🏻

wanna hear a joke? so the flat earther said, show me proof and I'll admit i was wrong.

A Flerfer got fired from my job for sucking at his job. He told me 0-G is filmed underwater, and I've heard that before from flerf videos, searched it, and I am so glad it's YOU here to debunk it!

my brain hurts so bad. Why would people not understand that bubbles float in the same direction? The most thoughts of all time.

“The Level films” lol 😆 you mean like the last one with all three contributing commentators being MMA fighters? Bryce Mitchel, Eddie Bravo and Joel Bauman enlighten us on satellites, rocket science and orbital mechanics. It’s hilarious.

I’ve just realized... I always thought that you, Dave, were soothing Rusty for having to endure such Clownitude. In reality... *he* is the one doing the soothing. Excellent Doggo! ❤️❤️❤️❤️🦴🦴🦴🦴 And I thank you, for your service to Science and Sanity. (There’ll be a little extra in your NASA Shill account this week. 😉)

Plot twist: Outer space IS water. After all, there's supposed to be water above the firmament, right? So we're in an air bubble inside an infinite ocean of space water. /s

I asked level earth observer how he thought the hatches on submarines ( or the practice escape towers) actually worked given that they are not floppy. No response so far

I simply love your videos Dave! Absolutely brilliant! And the best part is, you`re so to the point they cannot refute anything, instead they just do their usual rants and nonsense :D Keep it up mate!

All you have to do is look at the pool footage to realize that space footage isn't pool footage. You just have to look at it and be honest.

It can be fun to out-crazy them. Them: "the ISS is fake!" You: "Pfffft...you believe in space?"

oh, sorry, i missed the entire video because I've been looking at the dog

This gives them a purpose. They don’t actually want evidence. It’s all around them if they really wanted to know the truth.

Should I be shocked that LEO doesn't understand space? No. Should I be shocked LEO also doesn't understand water? Also no.

The fact that this video even needs to exist is extremely disappointing

I love watching your content, Dave. You are always knowledgeable about what you cover. You always explain things very clearly. And you are also always really 'relax and chill'. Also, I would like to know how a DSLR camera can stay underwater constantly, and still work 'on demand' like it is being used. How do people claim that it is underwater?

Thank you Dave. I've used to be a flatearther.... Thank you Dave to get me out of that hole... Lots of LOVE :)

Videos like this make me love and appreciate space and human achievements even more! Thank you so much for making these very informative videos!

Seriously....what's preventing flat earthers from literally walking to the "ends of the earth" peering into the void and hopefully jumping into said void?

Question: Do flat earthers know that in the southern hemisphere people see the moon upside down because they are actually upside down from the northern hemisphere? How do they explain it?

That hefty camera velcroed to the wall is a very good point ! 😄 I'd love to see what demonstrable earth realistic observer would have to say about that...

Thanks Dave and Rusty, very clear and concise debunking as usual.

I feel like your dog is a good metaphor for flat earthers(poor pup doesn't deserve such a comparison but hear me out)... He's sitting there, not doing anything, not listening to anything you say because he doesn't understand shit. And occasionally, he'll try to to get your attention for some dopamine. It's not a perfect metaphor, at least the dog is cute and fluffy but still

Another interesting thing is the amount of dead pixels in these video cameras. I read a long time ago that companies like Nikon never transport their cameras by air, as it at high altitude exposes the sensor for radiation that damages pixels in the sensors. Just look at that last shot of them looking through the window.. Dead pixel galore.

Here’s my argument to why the ISS isn’t underwater and can’t be Space wants to cause an explosion Water wants to cause an implosion It’s very hard to prepare a single craft for both problems, so now why would the ISS want to be prepared for explosions if it’s for implosions

Excellent video once again! Your attention to the details and logical explanations are epic!👍🏾👍🏾👍🏾

I find it quite hilarious how flat earthers call NASA a fraud, while there are a bunch of other space agencies, yet those ones aren't involved in the conspiracy.

If it is underwater, how did they get all that water into space?

Happy to watch your videos. Always learning something new. I like your calm and elaborated explanations. And Rusty is doing his best too!

I wish LEO many successes in moving a flimsy hatch under the surface of a water pool. He has not thought that out properly, has he?

nice video with good explanations and examples of how this cannot be under water. There is only 1 thing I wish you had mentioned. Refraction and the astronauts helmets. If they were indeed underwater then refraction would be making their heads look super tiny inside the helmets. Can compare to shots of astronauts on spacewalks and see their heads are normal size without having to worry about refraction from being underwater. I think Sly Sparkane did a video showing this many years ago.

2:45 Excuse me, sir, I believe you stopped petting me by accident.

I've been following all your videos and I really love seeing everything explained it's fascinating it just makes me more interested in the amazing work these people do for science. :)

Near the end of this video, it shows an astronaut entering through a hatch after an EVA. (He is met by a male and the female with the photo camera) As the claim is that the EVA is actually underwater ... then WHY is the astronaut COMPLETELY DRY and the is NO water dripping of him ?????

Always a pleasure seeing a new video from you Dave. Now if only the conspiracy theorists attempting to engage with you could match your friendly, rational attitude. (pokie seemed nice though)

Once again it just goes to show that, with the amount of work and special effects and tricks NASA and others would have to go through to fake the ISS and space walks, it would just be easier to actually go to space.

But if they stick their fingers in their ears and yell "CGI CGI CGI" over and over, then they can refute everything.

The ISS is actually not cannon in this universe, it only exists in the Kelvin timeline

What a nice feeling seeing your video after 50 seconds from posting it..😅 You're doing great by debunking their arguments without leaving anything for them .

Debunking claims that the iss is underwater. "Plays a video of Chris Hadfield playing guitar whilst aboard"... Well that was easy.. next?

LEO’s underwater floppy hatch idea is mind boggling really. How many submarines with floppy hatches has he seen? How clueless he is.

Where has all the water gone from the suit when they get back into the space station? They should be soaking wet according to L E O...

NASA tried developing the tools necessary for all these parlor tricks, but then realised it would be cheaper to actually build and fly the station up there instead

Hey Dave, I found your channel about 2 months ago and it has quickly become one of my favorite channels on RU-vid, thank you or the excellent videos, keep it up!
