  Weigh one ton of feathers there.

  Of course it will

  You're loading the feathers on the moon scale, at a rate of 84 to 1

  In other words, the gravity on the moon is 16% of Earths

  It is so little that the astronauts walking up there, have a tough time knowing which way is up. While walking. They trip all over the place, and have a hard time getting up righted.

  I also scuba dive. DEEP! In pitch black night dives, you have no sense of up, down, or sideways. When in sunken naval vessels retrieving items, many divers get disoriented due to the weightlessness.

  Panic ensues, divers die. They never remember to purge their regulators, to see which way the bubbles go. Air bubbles always go up. You have better vision at night with a dive light in your hand, in many of the worlds oceans, that you do during the day.

  It is so dark at night, you can place your hand directly on your mask, and NOT see the outline of your fingers. That's as dark as it gets.

  The fluid in your ears touching tiny fibers, are the controllers to your brain, to let you know which way is upright while on the planet, along with your eyesight, to confirm the signals from the liquid in your ears.

  This is why people get car sick and ocean sickness. They do not see movement, if reading a book in a car. The signal from the ears, are saying you're moving, but the signals from your eyes, tell your brain you are in fact not moving. Conflict, and sickness ensues.

  Diving is weightlessness, when buoyancy compensation has been achieved. During the day one can see the bubbles when exhaling, At night, Nothing until you turn your light on.

  Entering any type of ship, is the most dangerous undertaking, besides depth & time, while diving. Imagine going into a upside down ship where the walkways in the corridors are above your head. It is very easy to walk normally on the floors upside down with corrections in buoyancy, during daylight.

  Now imagine darkness you have never witnessed before, and doing the same thing. You will become disoriented, and trying to leave the ship, you will walk the stairways upside down, until you reach the bilge room. Bottom of the hull, not the top, you thought you were heading towards.

  This is where most inexperienced divers lose their lives. All they needed to do was purge the regulator, and they would have seen the bubbles going towards their feet, thus relocating their sense of direction. Time to walk on the ceiling to go up.

  Astronauts are given this exact same training in pools to understand zero gravity, and low gravity effects on the brains balance tools we possess.

  Weightless on the moon is as difficult in the ocean. Most rocks weigh less under water, as well.

  I have 2 bags

  1 with a tonne of feathers,

  1 with a tonne of concrete

  dropped from 10 meters

  which would hit the ground first?

  take same bags to the moon

  which would hit the moon first?

  A ton is a ton, be it a ton of feathers, a ton of steel, or a ton of styrofoam.

  Assuming the bags are the same size, in the same orientation, and the 2 bags are released at the same instant both bags will hit the ground at exactly the same time.

  On the Moon the bags will take a bit longer to fall because the Moon's gravity is only about 1/6th as strong as Earth's.

  For those that don't get it - Everything that has mass has some amount of gravity - you, me, your car, a dime, a leaf, everything.

  To keep it simple use Newton's law of universal gravitation - He figured it out about 340 years ago.

   

  • F is the force between the masses;
  • G is the gravitational constant (6.674×10⁻¹¹ N · (m/kg)²);
  • m₁ is the first mass;
  • m₂ is the second mass;
  • r is the distance between the centers of the masses.

  Reminded of old joke. 

  How can you tell that an engineer wrote a recipe for fried chicken?

  great replies

  1 thing everyone forgot

  the moon has no air

  therefore gravity does not exist on the moon

  the answer is

  both will hit earth or moon at the same time

  ApexPC:

  Everything that has mass has some amount of gravity

  So you are saying ,essentially, that all "Matter" has mass.

  The four types of matter are Liquid, solid, gas, and plasma

  Newton was unaware of plasma. Today his disciples spend years in training learning when and how to shut their eyes to it. It’s not just the Big Bang, General Relativity, and Quantum Mechanics that are in trouble but the foundation of them all: Gravity is an exhausted and bankrupt concept. A higher, more comprehensive foundation is needed. The technologies of gravity have lifted us to a viewpoint that’s bigger than gravity, and we need new ideas and new tools to make sense of the new vistas.

  Gases lighter than air like hydrogen, & helium have mass, yet gravity has zero effect on them.

  Plasma is readily blasted from the sun in Coronal Mass Ejections, into space escaping the suns magnetic field all the way to, and past Earth. The suns gravity, (biggest baddest in our neighborhood) has no effect on plasma.

  Ask any scientist worth his yearly grant money, "What is gravity"? a truthful one will tell you. "I don't know".

  Given the distance of 30 meters in the question, you're correct, they will land at the same time. Add more elevation to the equation and a new set of rules apply.

  We need a different type of math to find the answers of the universe. All scientists do is create new theories, to explain what outdated math will not. They get together and say, "this new theory is the new game in town", we will use this to baffle with bull shyt for a while.

  10 years ago, there was NOTHING between the many galaxies out there. Now all of a sudden, there is dark matter.

  Fookin brilliant! Can't see it. Can't touch it. Can't catch any of it. Just take our word for it, it's there. It will only cost 40 billion this year to learn more about it.

  Same results in a year.

  Sign that guy up for another grant, will ya.

  Because of gravity, if you drop something, it falls down, instead of up. Well, everybody knows that! But, what does this really mean? What is gravity?

  Gravity has played a big part in making the universe the way it is. Gravity is what makes pieces of matter clump together into planets, moons, and stars. Gravity is what makes the planets orbit the stars--like Earth orbits our star, the Sun. Gravity is what makes the stars clump together in huge, swirling galaxies.

  A great scientist, Albert Einstein, who lived in the 20th century, had a new idea about gravity. He thought that gravity is what happens when space itself is curved or warped around a mass, such as a star or a planet. Thus, a star or planet would cause kind of a dip in space so that any other object that came too near would tend to fall into the dip.

  This 2-D animation gives an idea of how gravity works in 3-D.

   

  

  Quite a number of experiments show that Einstein was right about this idea and a lot of others. But there are questions for which even Einstein had no answers.

  For example, if gravity is a force that causes all matter to be attracted to all other matter, why are atoms mostly empty space inside? (There is really hardly any actual matter in an atom!) How are the forces that hold atoms together different from gravity? Is it possible that all the forces we see at work in nature are really different sides of the same basic force or structure?

  Could some of the same laws of nature be at work in the designs of all things in the pictures above? These are big questions that scientists and ordinary people like us have wondered about for a long time. For a long time we haven't known how to go about finding the answers, other than trying to work things out on paper. But now NASA has a special program, called . . . for seeking answers to these and other mysteries of the universe. Fundamental Physics hopes to do two things: To discover and explore fundamental physical laws governing matter, space, and time.   To discover and understand the basic rules nature uses to build the complex and beautiful structures we see around us.   Over the years, scientists and engineers have developed new technologies and instruments that will help us understand nature. Now we can take these new instruments into space and do experiments where the forces of gravity are very, very small (like when the Space Shuttle or the International Space Station are orbiting Earth in "free fall"). This way, scientists can do very delicate experiments to see what single atoms do under special conditions. NASA hopes these experiments will help us understand our universe and ourselves. NASA also hopes the experiments will help develop technologies that will benefit people in their everyday lives.

  Now you're just copying & pasting outdated physics. At least you know what you're looking for.

  This is it for me. When these supposed genius' (scientists ) figure this out, as their new foundation of math, we'll be getting on with things...

  Scientist, theoretical, or not, need to know this new math

  Now that's an everyday formula for the uninitiated...

  Find the value of "U"

  Just fecken with you bro  :-))

  What keeps them in our atmosphere then, why don't they just leak out into space?

  Dude, you ask the tough ones don't cha?

  Every scientist in the world will tell you GRAVITY. However they can not explain gravity.

  We lose trace elements (gaseous) every second into space due to the solar winds. The molecules have to be traveling 7 feet per second I think to do this. Most particles rotate with the earth not shoot straight outward into space.

  Now that's their story, and they're sticking to it, like that stuff on Aldrin's boots.

  If I may be so bold, I believe, it is the magnetosphere that keeps our atmosphere pressurized, thus not allowing the entire atmosphere to be stripped away.

  There is very little energy holding an atom together. This is another quandary for the pseudo-scientists. You've got protons & electrons buzzing around the nucleus, but no one knows why they stay there. What force holds them in order.

  Electromagnetic fields, is the answer, more so than gravity.

  It's all magnetics in fact that keep us as water, bone bags together. Positive, negative push and pull on every atom in us, and surrounding us. We displace a certain amount of energy where ever we are. Just like a ship in an ocean.

  Like a plane, or a submarine, energetic pressures rise dramatically when we fly higher and dive deeper in the ocean. All atoms being equal, we survive at the 1 G zone very well. Under extreme pressures our bone bags crush from to much pressure.

  The magnetic pressure is more attractive the closer you go towards the core, as well as outward to the magnetosphere. The electron forces are reacting with the environment around us, essentially, ( this slays me after today with you) gluing us together and keeping us on the planet.

  There's more to this, however it's getting late here, I can only imagine what time it is there. 5 hours I think difference.

  If anyone grasps this concept, you do Paul. I know this will be by no means, the end of a long line of questioning, haranguing, LOL, and everything else you can get in the pot.

  So I thank you for playing along, and bid you adieu, for the evening. 

  No stealing my hypothesis, and turning a paper into the scientific journal before I do. I call dibs on all my pseudo science...
