"When you think something is true, you really should try as hard as you can to disprove it." Christ this is a good quote.
This is true I spent a while checking sources to see if flat earth is possible I even went on some flat earther gura channels sadly for some reason what the gura was saying sounded like nonsense to me with really obnoxious music in the background no comments explaining making it really hard to understand from their point of view just not proving their point at all where sphere earth explained things in detail saying what this thing is that and not this instead you know
That's ho scientific reasoning works
@Waldel Martell are you s flat Earther or something? I never said gravity

Good luck, flerfo!
You mention Christ and he is a good example oi this, actually.

Technically people are not afraid of vaccines perse, we all witnessed their validity growing up. It's more the concern now that additional vaccines are being introduced that are seemingly unnecessary, outside of the handful of true stories where a child changed dramatically after a vaccination. Skepticism is a primary factor in human evolution. Also knowing that our media IS propaganda, it should be easy to understand the person who is skeptical about putting something into their children that is presented by governments, who themselves are proven to be untrustworthy.

I see a new use for the worlds roundest object!
XD I was thinking the same thing when he said the object can't have any surface roughness
So if there's a giant sphere and a laser hits it then there would be a laser at the other side that's weaker and smaller then if you used it to hit another sphere there would be another small laser,theoretically there should be many spheres and many smaller lasers until there is only a laser the size of a single photon that can't refract around another sphere 1: there's no sphere small enough 2: the photon would haft to refract all around the sphere to create the laser. On this. Theasis it's possible that a satalite (astronomy wise,not a satalite like a tv satalite) should be able to create this laser on the other side possibly like there's a hole in the object; imagine how cool that'd look... NASA should use a perfectly round object to orbit earth to see how cool that'd look
Jokes on you I can't see anything.

@Aidan Snyder in what way is it disproven
@Aidan Snyder I don't want to speak over the real facts because you're biased, but I'll also make the effort to answer respectfully, and I think it's an important point. I don't agree with your "edit", you're saying people can't accept major unanswered questions anymore. However, science does, and religion doesn't. In fact, what did the people when they couldn't find answers? They created gods to explain. Science doesn't claim to know everything and that's exactly why scientific theories exist. A scientific theory is something that is based on facts and observations, you can upgrade it or disprove it when you find new elements. What happened with the evolutionism ? It's is based on millions years of proofs and facts and everything matches perfectly. Every year we add new elements which make it more reliable.
What I find fascinating, is that creationists claim to use science to disprove evolutionism, while creationism has absolutely no scientific proof. Stephen Hawking once said: "The Universe doesn't need God to exist"
@Aidan Snyder I have read your entire comment. I'm willing to teach things to uninformed people who want to learn, but not to creationists, because they will never change their mind. Arguing with people who do not want to recognize anything is wasting my time and depressing. Then, as I implied, I see myself as an agnostic, there is absolutely no evidence of the existence of God, and the Universe does not need him to exist, but nobody has a proof of it's non-existence, which is basically impossible to prove. I also remind you that the Bible is not a scientific document, and that is an indisputable fact, there is no debate on it. Since you don't agree, we apparently don't have the same science, or we don't live in the same world.
The theologians and the Vatican said that God gave "an impulse" to create the universe, but they agree on the scientific explanations like the Big Bang and the age of our Earth (~4.5 billion years) because they cannot deny it. The Church here in Europe said clearly that we cannot read the Bible and take everything in it litterally. And this time, it's not my opinion...
Also, the Earth is'n flat, and it's statistically absolutely impossible that we are "unique" in the Universe. It's just common sense don't you think?
Thank you for your respect, and have a good evening.

And then Einstein managed to get the Nobel Prize in physics for demonstrating that light can, in fact, be viewed as particles after all. But of course, phenomena such as the one shown in this video demonstrates that light still also has properties of waves.
+Eugene Khutoryansky But he was mistaken. Einstein has a hoax. Light is waves. cant be both man. Seriously.
+Eugene Khutoryansky
I have heard several talks of theoretical physicist Sean Carroll who says it's definitely a wave. (yes, available on youtube)
+Mc Einstein en.wikipedia.org/wiki/Wave%E2%80%93particle_duality
+Thulyblu, yes it is definitely a wave. It is also definitely a particle. Hence the wave particle duality of light and everything else in the Universe.
Particle-wave duality. Every elementary particle or quantic entity exhibits the properties of both particles and waves. The classical concepts "particle" or "wave" cannot fully describe the behavior of quantum-scale objects.

+jeneau saunders You'd probably have to wait for one to just happen to float right past the center of your eye.
+jeneau saunders Problem is that you move your eye when you want to try to look at it. And the floater is moving with it... in the liquid.
+jeneau saunders the trick is not to chase the floaters but concentrate on one thing and let them follow you.
As airline pilot, I see fresnel's bright spot all the time... When you are at around 5000' in a cylindrical object like a fuselage, you can see a bright light until you get close enough to the ground and the shadow is less diffused to show the bright spot... The light basically diffuses around the cylinder at a particular altitude and all the light around the fuselage is shown inside the shadow... Derek, if you want me to show you this I can get you videos on this anytime as I see this everyday in my line of work
You've changed the way I look at my eye floaters forever! :-)
In lighting for film and TV, we often use rectangles of black cloth stretched on a lightweight metal frame to create shadow areas. These flags or cutters as we call them are held in place by special "C" or "Grip" stands along with arms and knuckles that look like huge tinker toys.
Over the course of the years I've noticed that when the flag is twisted so that it is more or less in line with the beam of light instead of perpendicular, the edges of the shadow caused by the flag has a brighter line next to the shadow of the flag. I'd wonder if this effect is a manifestation of Fresnel's theory, only linear rather than circular?
Not only do I see it with my very own eyes... I see it *in* my very own eyes.

But while I didn't ask many people, The few I asked said they don't really see anything.
I never knew what they were until now.
I thought it where Some sort of bacteria(or small hair/dust) .i asked a doctor What it could be, he looked at me like i was seeing "things" like halucinating. (Shitty doctor perhaps) Now i know. Some science is going on in my eyeball. First time i Hear other people see this to. Nice to know.
Actually those are things floating around in the fluid in your eyes.
I'm so happy others have seen these things cuz of talked to all my siblings and some friends and there all looked at me like I was crazy
On the iron-sight of a C7, on the long-range setting, the whole is made in such a way that there will be a destructive interference point in the middle of the sight that you can line up with the pin at the canon end of the weapon.
It's insanely precise for an iron-sight and works off the same principle!

"if you wants to see the light, you have to look at the shadows"

Veritasium, I have to tell you that I think you are the smartest vulgarisateur I have ever heard of. Any time someone comes to me to know more about science I tell them go and watch Veritasium. One day we will meet and will thank you for all of that !!
his conclusions are so bang on love them !
Use a non-reflective marble, otherwise it could be an odd reflective ripple.
Or... Don't. Either way.
A Vantablack marble perhaps?
I thaught about that too. I would recommend a flat circular object maybe coated with something like vantablack.
actually, I think someone might produce a shadow at the center of 'round light' using Babinet's Principle :)
or a simple focusing effect that always happens with glass spheres.
is there a bright spot in the centre of a solar eclipse?
Men, probably.
You should try to see it
The sun is not a coherent light source so the effect would not occur
Well maybe....u cant see the spot on moon's surface....the poisson spot would be in middle of the shadow of the moon on the earth's surface....and i guess u can't go to the moon to see it. And the possibility is there because moon's diameter, it's distance from earth, and the wavelength of visible ray is satisfies fresnel's number which is needed to be >1 for poisson's spot....
you wouldn;t need to be on the moon to see it, if you where on earth at the bright spot it *should* be as light as day despite being in the moons shadow.
The mind-blowingness of this experiment put aside, pretty relieved floaters are normal.
This thing actually blows my mind .

This is one of the best physics experiment i have ever watched on you tube ❤️
Oh my god i always thought about the stuff i saw in front of my eyes when i stared at the sky now i know thank you
did you watch the video at all victor??!
@Victor Giaquinto did you really watch the video?
@@Ultiminati Once again, that's not the exact cause of the "eye floaters"
Here's a more in-depth video about them czcams.com/video/Y6e_m9iq-4Q/video.html
Don't know why everyone is slamming on Victor. He's correct.
If anyone was paying attention to the video, it's Victor...
Eye floaters have nothing to do with the phenomenon portrayed in this video.
Eye floaters are caused by tiny flakes of debris in the fluid filling the eye.
When starting at a uniform, bright surface (such as a blue sky on a sunny day), the shadows this debris causes are cast on the retina, and the 'floaters' we see are these shadows.
In the video, we're just observing a bright spot caused when a coherent light source strikes a round object.
Constructive interference causes a bright spot to appear, under a very controlled set of circumstances.
Sky-light is not coherent at all, eye floaters are very rarely completely round, or spherical.
I'm not saying that an eye floater could never exhibit the effect portrayed in this video, but it's really got very little to do with why we see eye floaters in the first place.
Am I the only one who considers this channel by far the most science oriented on CZcams? Am I alone on not caring too much about "Lava on Dry Ice" and all the other click bait "Science" videos? Kids are watching, making them smarter here. Bravo Prof Muller:)
And I'm sure this video is coinciding with the several "Blood Moon Eclipses" we've seen recently, where instead of planet earth blocking off all light towards the moon it was instead refracted by the atmosphere creating a red eclipse. Would love a whole video devoted to "floaters" 6:32. I see them looking at my screen so I wonder if focus has anything to do with that.
+fla playa Well, there's nothing wrong with a little "clickbait" science every once in a while. Remember, 90% of science is just screwing around.
TheRinzl2r Except for the simple fact of all time low ACT scores for 2015. Other then that fact I would agree. Time for being smaart Agian or we will lose. (not your grammar by the way) :)
I think I saw this awhile ago but it still blows my mind
A cool thing about this video -and most of them- is that it starts from something we all know, to guide us to to deeper science. On the other hand, I don't completely agree with calling Poisson's idea a "mistake". He may have been wrong in his assumption of light being particles(*), but that did not prevent him from drawing a correct and interesting conclusion, based on the assumption that it would be a wave. Thinking so hard about a competing theory is an accomplishment in itself. The only regret is that he didn't actually perform the experiment.
(*) was it actually wrong?: first of all, in those days, the debate particles/waves was unsolved, so he *couldn't* know. Secondly, light obviously also has a particle character, so he wasn't completely wrong after all.
omg!! Thank you so much Veritasium I'm so glad now! I always thought that my eyes have problems because I always see weird things floating around my eyeball !! thank you so much man !!
i wish i could remember the informations ive been struck with through all of these knowledge-filled videos
While you mentioning the eye floaters, there are also string-like eyefloaters, which result in a line-like spot.
So, I think that it can also be visible with a capsule or cylindric objects. The important property is the light source. Directional lightrays is key.
You have the proof with the double-gap experiment. The distance between the gap (diameter of sphere or capsule) and the resulting inferences. Also the wavelength could be influencing the inferences (my assumption).
Thanks for this video.

+AMaleWhale They are said to be more frequent with age, so it might just be that you don't have too many of them yet.
I have some, but hardly notice them unless it is a dim light setting personally
+AMaleWhale Poor vision maybe. You really should be able to see them if you look at a blank blue sky. (No clouds, just a solid tone). And just stare straight at the sky.
No in fact it means you don't have something wrong with you. Floaters are a defect.
+AMaleWhale You tend to see less of them as you age, old man!
Dude! Best video yet
