Imagine being proven right about something like this half a millenia after you're dead.
So sad he never live to see his answer be correct.
@@destroyerdog Not sad, _glorious._ Galileo knew he wouldn't live to discover all the answers he sought, but he went on seeking them anyway--even though it cost him his liberty--because it was worth it if only to pass on that legacy of inquiry to future generations. Think about that.
His findings was proven long before Apollo 16. This was just a great visual experiment
He wasn’t proven right with that, in fact, he proved himself right back in the 16th century. You can prove his findings to be correct at your own home.
If the church had all the power, we wouldn't have gone to the moon to experiment such evil things in the first place 😂
You can hear his smile in his voice. I love it.

When he says that one of the reasons we got here today is because of a gentleman called Galileo, it really brings into focus the achievements that humanity can make when we try. That one man centuries ago decided to start doing experiments and studies, which one day contributed to humans walking on the Moon and talking fondly about him and his work.
He and the many other scientists and discoverers like him would be proud.
The astronauts from the USA did NOT land on Moon until 1973. They had a lubricants-freezing problem in their suit in the shoulder gears in 1973. Any human landings before are fake.

No Moon mining, please.
Moon does NOT self-rotate.
Moon is hollow.
The Moon gives light at night to help grow vegetables and fruits by 20%. This helps to reduce famine, inequality, and wars on Earth.
If Moon is mined, it will be punctured and shrink like a broken flat basketball. It cannot spread light to the surface of the Earth like a convex mirror. It will ONLY reflect to tiny dots on Earth like a concave mirror.
There are invisible structures around Moon to keep the Moon inflated. The inside of the Moon is hollow, like a basketball or soccer or our lungs. When the lungs are expanded, the pressure inside is lower than outside. Moon has higher pressure outside on the surface than inside. The frequent fly-ins and fly-outs of Moon rovers, orbiters, and spacecrafts would puncture the structure and destroy the Moon. Earth will have more wars and famine and more inequality.
Also, there are aliens (Gods who created and managed this Universe and Earth) living on Moon. Please respect them, and do not disturb them. Whoever lands or mines the Moon will be hurt or dead, and no return as punishment.
Under the Moon are lots of pyramids. Earth Human-made nuclear explosions in the past wiped out humans on Earth. The dust also blew to the Moon and covered them up. Moon is dark in the front face, and clean and bright in the back side, because Earth human-made nuclear explosions burnt from Earth to Moon and beyond, again and again; one round of human civilization kills themselves with nuclear, next round again, then again, till now. Each round of human civilization did not last for about 4800 years.
There will be 3 Moons around Earth.
Now the 2nd Moon is built and stored near Saturn.
Right now, Earth would be even hotter if the 2nd Moon is brought near Earth.
Please, no Mars colonization or Moon mining. Please, no nuclear in Space or on Earth. Every Moon and Planet has aliens living there. Aliens are at least 50 years ahead of humanity. Humans are bad, having wars all the time. Human invaders on other Planets and Moons will be killed. Acts of revenge have started-many huge cyclones around launch sites. Please recycle space junk. In the solar system, only Earth has water; other Planets and Moons have no water. Another Planet that has water is in the Milky Way 7th cluster.

Mission Apollo 15, 26 july - 7 august 1971. Scott verifies Galileo's theory, that objects in a vacuum fall together, using a hammer and a feather.
Yes, that is what happened.
After watching the video, I can confirm that is what happened as well.
Surely they had already tested things in a vaccuum in a lab before this!
This was on the third moon walk on the Apollo 15 mission, and Scott's NASA issued Omega Speedmaster watch had not survived the previous moonwalk, and instead he had to use his private watch which he was gifted from Bulova, whom asked him to wear it. The watch was a pilot watch design that Bulova had hoped should fall in favor of the astronauts and thus make NASA "hopefully" make a contract with them instead of Omega. As it happen, Scott brought his one on the mission as his "private/spare" watch and after the Omega failed due to it's crystal popping off because of the conditions on the moon, Scott asked for permission to use his Bulova on the final moonwalk, NASA did grant him this permission and so it was that Bulova got into the highly prestigious moon history. For years this was not remembered until just fairly recently when a man studying the pictures from that mission and was curious about that watch David Scott was wearing and so he contacted him, and suddenly Scott remembered, and he even still had the watch. The watch was sold on auction for a solid $1.6 million dollars, and soon after Bulova made a reissue of this now famous "other" moon-watch.
Curious you left out the stamps.

Agreed. A combination of the failure of public schools and the misleading nature of the Internet has led us here.
@@281cu6
But there is less. But it is lack of friction in the air that causes hammer and feather to fall at same time, right? This isnt abt gravity, per se.
There would also be many people who think all you have to do is ascend to 100km altitude and there's no gravity.
@@seedsoflove7684 Yes, exactly. The hammer & feather thing is all about air resistance or the lack of it. Same ring could be done in a vacuum chamber on earth.

Mars has an atmosphere which could influence this experiment. This works in a vacuum
@@conradsz Mars's atmosphere is predominately CO2 and a lot thinner so it would be very interesting to watch the movements of the feather.

Well, Elons looking to go there in case electric cars aren't the answer.
he just drops the casual "How bout that?" like a true professional
how can u be so gullible😲
This is one of the best examples showing, we really went to the moon. Both the feather and hammer took about a second to reach the ground. On the earth, it would take roughly about 0.45 seconds (assuming about a 1 meter drop t=(2/9.8)^1/2 ) You can’t fake gravity. And for those who would say, they slowed the video. That wouldn’t work either. The video technology to slow the video smoothly at that time did not exist. It would have been obvious the video was doctored.
This is so memeable
I would want to drop a helicopter seed on the moon to watch it not spin because there is no air to interact with.
I remember my 8th grade science teacher showing my class this video. He was the coolest science teacher ever!
For all the kids in school at that time, the trip was worth it!
I saw this experiment as a kid, myself!
This experiment proves the theory that all objects fall at the same rate in vacuum regardless of mass, because gravity is not a force as in pulling things towards itself but rather the gravity of massive objects bending the space time continuum which as a result causes objects to head on a collision course and eventually collide with it.
Anyways you can treat it as a force, with Newton laws, although it's not physically correct. Because g is constant, the force of the weight F=m.g will be proportional to the mass of the object, so F/m will be equal to the gravity acceleration anywhere and without depending on the objects.
No. This proves that air molecules effect gravity effect on things with mass.
@@dblshotz75 That makes no sense.
Space-time continuum.. What a great "theory"
@@jakefriesenjake He's correct. In our current understanding of physics, gravity bends both space and time, because they are both interlinked with each other.

@@fendermarshallbluesbox3407 a. We know the Moon's acceleration due to gravity by tracking the radio signals of countless Lunar orbiters and the effects of the Moon's gravity on said signals.
b. By clicking on stats for nerds, we can see that the FPS on this video is 30, which is identical to the framerate that the Apollo TV color cameras ran at (judging by the video quality and how the various cameras of Apollo 15 were used, the TV camera appears to be responsible for this video). Reducing the speed of the video would reduce the framerate.

Amazing what special effect can do !!!!
moon gravity looks really cool
Really you can demonstrate the mass thing on earth just using two dense objects of different weights. What Scott showed here is that an object that would normally be greatly affected by air will drop straight down in a vacuum. Which isn't all that surprising.
So lack of air resistance means birds can’t fly in space
And lack of getting to the moon means the feather was weighted. What a bunch of fools.
@@josephm495can you rephrase what you said?
@@justinknauf the experiments were staged as well.
@@abelpazos51 Birds can fly in space, but they can't control what direction they fly in. This makes it very difficult to nest in trees on the Moon, which is why they nearly all flew to the Earth where it is quite easy. David Scott was actually quite lucky to find that feather.
So this proves the moon mission as real, and the documentary called american moon as fake?
Super...
Galileo: Yeah, what about that?
Galileo would be so proud of the brave men for proving his gravity theory true. Don't worry, he was watching from heaven.
Galileo was actually quite brave himself to publicize the ideas he had when surrounded by religious nut jobs. He spent the last 27 years of his life under house arrest for his "foolish, absurd, and heretical" idea that the Sun was at the centre of our solar system.
@oldbloke135 Very true! It was messed up what people did to scientists back then because of new findings.
Why did it drop at the same time
No air resistance, so the feather has nothing to float on so
both are falling with the same gravitational force
Drag force is near 0, therefore the only force acting upon both is gravity.
@@arnavsinha834 No. The hammer is experiencing a greater force because the gravitational force is proportional to the product of the two masses (in this case the mass of the Moon and mass the hammer/feather.) So the force on an object at the surface of the moon is approximately: F~M*m. Where 'M' is the mass of the Moon and 'm' is the mass of the object falling near the surface. The reason the hammer falls just as fast as the feather despite it experiencing a greater force is that the acceleration 'a' an object experiences when subject to a force 'F' is: a=F/m, where 'm' is the mass of the object experiencing the force.
So, we can say F=ma instead of a=F/m, and plug ma into for F in F~M*m. Now we have ma~M*m. 'm' on both sides of this equation represents the mass of the falling object, so we have a~M, acceleration is proportional to the mass of the Moon. so no matter what we are dropping near the surface, its acceleration will depend on the mass of the moon, not it's own mass. The physical interpretation of this is that the inertia of a more massive object balances out the greater force it experiences when gravitationally interacting with the Moon (or any other massive object.)
@@arnavsinha834 Not the same force; the same acceleration. The hammer falls with greater force because of its mass, but it also requires greater force to pull down because of its inertia. Since mass and inertia are exactly proportional to each other, they cancel each other out and the gravity pulls both objects down at the same rate regardless of the difference in their mass.
“I told you” - Galileo Galilei
Can’t wait to see this in 320p in next nasa moon mission
I remember this, but the extra calculations and fuel to take a rusty old hammer into space, would provoke a long conversation in the mission planning room.
Then I don't think your memory is what you think it is. Are you claiming they decided to find a hammer with rust on it to bring just for this experiment? Are you claiming the hammer(s) they had for rock collecting wouldn't have been used?
@@kitcanyon658 And this is why NASA hammers cost so damned much!

Why does the background look like that when they zoom in and out?
If the moon landing was fake, how did they evacuate all that air to demonstrate that a feather and a hammer fall at the same speed?

It's a funny thing! Years ago, due to a misconception about the law of free fall, someone told me this. "If I jump off a cliff, and you fire a bullet off the cliff, at the same time, both I, and the bullet will hit the ground at the same time."
I tried to explain that this logic does not apply, as he is a free-falling object, while the bullet is being projected from the barrel, at a MUCH greater speed.
I so dearly wish that I had said: "This is true. However, that is only provided that the bullet does not completely exit your body. PLEASE don't make me prove it!"!"
I hate to burst your bubble, but if you ignore the curvature of the earth and terminal velocity (basically, done from a low enough cliff), this someone was correct. A horizontally fired bullet would indeed drop to the ground at the same rate that they do, it would just be quite some distance away when both hit the ground. I think you may have misinterpreted what they said and expected that it was fired downward.
@@poulanthrope I agree. This is a classical physics Quiz question. Someone was indeed correct.
Many Physics teachers have a test rig in the back of their classroom. Once set up, you release a steel ball that rolls down a ramp and "kisses a ball balanced at the bottom (tangential, the merest touch)the ball struck begins to fall as the ball that touched it wizzes by(long ramp) the entire class will hear as both balls touch in unison
I just think it's funny he pleads not to be hit by the bullet.
I've never understood how a rocket can propel a craft if there's no resistance in space. What is it pushing against to move the craft?
Reaction engines don't work like that. Neither jet engines, nor rocket engines. Not down here, not in space. When you sit in a wheelchair with bowling ball in your hand and you throw it away from you hard, you will roll backwards. And no, it is NOT because the bowling ball pushes against the air, instead it is Newton's third law: To every action, there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts. "momentum" is the product of mass and velocity. And when there is a momentum in the one direction, there has to be the same momentum in the opposite direction. In space you have no friction at all, so better like the wheelchair. If you are in space weigh 100 kg with the bowling ball that is 5 kg and you push it away with 10 km/h, then you will move backwards with 0.5 km/h . You can also take a bucket of stones in a boat on a calm lake, and you will move forward by throwing stones away to the back. Ever felt the recoil of a gun? You really think the recoil happens because the bullet "pushes against the air"? No, you will also feel the recoil in space. And a rocket shoots out gas molecules (that have a mass) with a certain speed to the back, to the rocket moves forwards.
Or think of an explosion. When you would put dynamit in a bowling ball (haha, that again), then the part will fly away in all directions. bigger parts with less speed than lower parts, but the product of mass and speed will always be the same in any direction.

_Dude would explode if he was in a vacuum in anything other than a very strong airtight rigid shell._
The Apollo astronauts were breathing almost pure oxygen with only 1/3 atmospheric pressure. That means that the pressure difference between the inside and outside of their spacesuits were _less_ than what passenger jets are exposed to at typical cruising altitude.
How often do passenger jets explode due to their cabin pressure?

What the fuck is wrong with this comment section?
Unfortunately, there is this incredulously large portion of the population, who refuse to, and/or are afraid to, admit that modern man, in defiance of all the gods that be, have achieved some monumental goals.
A large portion of the people are ignorant about science and basic physics such as free fall and it is pretty sad

@@StaciArdmore you said this already. You were given a reply that explained the statement.
"Science is just religion explained" was something I heard years ago. As a Christian (yes I do believe there is a God) I still trust science to search and at times find answers to the great questions we all seek. 100 years ago a cellphone would have seemed like magic, especially to the rural rubes of our planet who had no inkling of technology even of their own time. Magic is not religion or vice versa. Religion is simply the organized belief system in unexplained occurrences. Magic is fantasy. Science is fantasy made real through experimentation and evidence over time. Now I agree that my statements here in this reply are subjective and do not claim any expertise or unequivocal knowledge of truth in absolutes. And I say this without the advice of a lawyer. LOL have a great day and believe your eyes unless you don't want to. But please, stop trying to ruin it for everyone else!
Look at all the foot prints on the dirt and yet there’s NO blast crater? This is all fake! The men should have been able to leap 9 feet in the air and yet they never leaped more than 18 inches off the ground.
9 feet? You have actual calculations to support that claim, right?
What would the blast crater be from? All the flames shooting out of the engine in a no oxygen environment? They purposely cut the engine about 5-6 feet up to prevent issues with the bell and other damage to the LM. Even then, A15 landed tilted and sustained some bell damage. Have you ever seen a landing video? All the dust that’s ejected laterally from the landing site? Even in photos, you can see the striations. Further, wouldn’t the geniuses who “faked” the landings add a blast crater to convince people like yourself decades later that we went to the moon? Seems like they would’ve figured that one out by like the 4th or 5th landing.
And to add to the replies: Seriously? Would NASA send people to the moon with NO WEIGHTS in their suit so that the first time they try and jump on the moon they fly off into space and die?! How much school did you stay awake for? Go back to class and learn how to think.
according to what calculations?
Why would it make a blast crater when the engine is in a vacuum

@@Lambda.Function Unfortunately for you, unproven opinion cannot change facts.
@@raptorwhite6468 Convenient, define your opinion as "fact" and everyone else is therefore wrong by definition. But you don't actually have any evidence. I have a lot of technical impossibilities for the 60s and 70s along with no less than 100 experts in space flight from the last decade saying it's bullshit. You have what, video footage? We also have video footage of Matt Damon on Mars. That must be a fact now too.
@@Lambda.Function 100 experts? Probably similar to that flerf pilot who turned out not to be one.
If you want evidence, here you go:
- the footage couldn't be faked in any way in 1969, for example the recording of lunar module returning to command module, with moon in the background. It goes on for a long time, showing hundreds of square kilometers of extremely detailed lunar surface. How? Did they make a perfectly detailed model of it? It's impossible
- retroreflectors are on the moon, still being used today to measure its distance from us. I know what you're gonna say about this one - it could be an unmanned probe. But a probe wouldn't have been able to put it there with such precision and it would mean you have to give up on your favourite "proof" - Van Allen belts, they're just as dangerous for probes as for people
- USSR admitted US landed on the moon. No one would want to find evidence against it more than them, yet they haven't. Does that mean they're qualified scientists are less enlightened than you? No, they just know what is a proof and what isn't
- shadows cast by astronauts on the moon are very sharp, even today when making movies about the program, nobody was able to replicate these shadows in a studio
- missions brought back over 100 kg of lunar samples, significantly different from anything found here on Earth
- flights has been tracked and listened to on their way to and from the moon by many different countries and even regular people
- photos of landing sites have been taken by lunar reconnaissance orbiter and chandrayaan 2
I would be able to find more than that, but I've got better things to do
I couldn't imagine what would happen if the hammer would reach the surface of the moon faster than then the feather...😂
