  1. This is absolutely wrong. It is convenient that you ignore my reference to the Apollo 15 demonstration on the moon, which you can view http://www.youtube.com/watch?v=5C5_dOEyAfk.

    I have seen many pic. and videos of different NASA missions for MOON. I have noted some similarities in these photos and videos,

    Size of the shadow remains the same in every video

    In day time the back ground remains always black and few stars appear shining in the background, which is quite against to the day time on the earth, as we see every thing bright on the earth in the presence of sun light.

    http://www.youtube.com/watch?v=PimI6HRlKjQ

    In the above link video we can see a man is struggling to walk on the surface of the moon and this causes the dust to lift above the ground. After lifting from the surface it settles down very quickly as it does on the earth surface.

    I think if a massive man is struggling to walk on the surface then the dust should also travel some distance or take some time to settle down on the surface because the weightlessness behavior should be valid for both if there is any such behavior.

    In a free fall of feather and hammer both fall at the same rate on the ground if we consider this correct then what causes the hammer to slow down its speed in free fall on the moon?

    Please correct me may be i am wrong and fails to understand the basic concept

  2. Both of your statements are incorrect. Increasing density does not increase gravitational pull. The gravitational pull between two objects is proportional to the mass of each object, and inversely proportional to the square of the distance between them. Nowhere in that statement does density enter into the equation.

    Calculated value of force between Earth and Moon is 2.1233E20 N approx

    and between Sun and Moon is 4.351E20 N approx. which is much higher than the force between Earth and Moon. Then how is the solar system working and existing in the light of Gravitational force? It is quite illogical and false to explain the Solar system through Gravitational force.

    By keeping in mind how can you justify and balance the force between Earth, Sun and the Moon when there is a total eclipse of Sun or in normal conditions.

    My point of view is about the possesion of moon when it is in between Sun and Earth.

  3. Galileo demonstrated this fact at the leaning tower of Pisa. Commander David Scott also demonstrated it on the moon with a hammer and feather, which have very different densities.

    Galileo was the first man who told us about the behavior of falling objects having different weight.

    Galileo dropped a cannon ball and wooden ball from the top of the Tower of Pisa.

    This story is apocryphal, while some of his earlier predecessors actually performed this experiment, and found in fact a slight difference in the time the two balls struck the ground.

    Although the Leaning Tower of Pisa is there but no one successes to do it again. There is only one possibility available for both balls fall down at the same time when both have the same densities, otherwise there should always a difference in the time.

  4. If you mean Dr. Abdus Salam, he went to college and received his PhD at Cambridge, England.

    I assume you did not receive that education, or a similar one to his. The only connection between you and Abdus Salam is your nationality. In fact, you're his exact opposite: you're probably the most irrational person to ever post on this site.

    If you want anything you have to say on the subject to be taken seriously, I suggest you study Physics, and the scientific method, first. Nothing you can come up with has any value until you do that.

    Thanks for your suggestion

  5. You're using the authority and esteem of the Nobel prize to help argue that the past fifty years of Nobel prize winners have all been wrong? I'm pretty sure they've all accepted the theory of gravity in some form.

    But i also believe no one get this prize due to gravity.

    This is not my aim to show any one inferior.My basic point is that there is always some cousion of improvement .Due to this improvement we are achieving and getting a new aspects in science every day.

  6. Gravity is the "force" that implements containment by existence.

    Without containment by existence, you are out of this world. You can't base a theory of physics solely on local, directional interactions, you must have a global containment to create systems. (This is true conceptually too, but that is a much more involved topic.)

    - David

    I agree with you David

    Let 's take an example

    Took a pipette and filled it with water then hold it by putting the thumb on the top of the pipette.You 'll see the water will never fell down although the gravity is there then what is the factor that is controlling the water in the pipette

    Actually the water that is traped in the pipette is suspended due the air.Air is a refrence medieum in this earth.When we closed the top of the pipette the connection of the water with the air became vanished and the water became suspended in the pipette because there is no more refrence medieum or force according to the 1st law of motion.When you remove your thumb from the top after that the water will fell down very quickly ,air pushed the water that is the real refrence medieum.

    In this experiment ,some more factors are also involved but essence is the diffrence in densities of object and the medieum.

  7. complete balderdash! your theory cannot explain the Cavendish experiment.

    In this universe every positively charged object will attract the negatively charged object and the same charged object will repel each other e.g if you rub a comb with a cloth it will be negatively charged then closer a piece of paper it will be attracted by the comb same is the case with Cavendish experiment

  8. What about physics? They must teach that there. Maybe you went to some school teaching Pre-Socratic Greek "science" or something. ;)

    very funny

    Dr. Abdull Salam won the Nobel prize in Physic.From here you can measure our caliber and approach in Physic.We do not read the science just like a story or a holy subject

    that can never be changed or modified.

    Try to prove your objection on my theory through knowledge and examples

  9. What force is acting on the less dense "mouth air" filled balloon causing it to fall towards the earth? What about a stone dropped in water? No gasses there (essentially).

    U are misunderstanding the core concept of the theory

    My theory based on two things

    Density

    Pressure

    In case of mouth air ballon is under the influnce of atmospheric air.As the densities of the atmospheric air and the air which is present in the ballon are almost the same thats why ballon remain on the earth.

    And in case of water,the affecting medieum is water not the gases because the stone that is falling in the water already coming after crossing the air.when it crosses the medieum of air it will enter in the next medieum that is water now.if the density of the object is less than water it will float on the surface of water e.g paper

    if it is more dense then it will penetrate into the water just like stone

  10. Bukhari, your idea does not appear to me to add value over and above existing physical theories. I urge you to check your premises and be more deliberate in your inductions. So far, your posts appear to express more or less whimsical connections to observable reality.

    Now, if it is simply an issue with lack of familiarity with English, then maybe try writing your ideas in your native tongue and getting someone to help you translate them more faithfully. If English is your native tongue then this cannot explain your lack of coherence.

    - David

    Thanks david, english is not my native tounge.I will try to mange a translator

  11. Really? So the fact there is all this evidence for gravity does not seem to phase the original poster. Or the "math" guy leaping to his support ( at least I think that is what his arbitrary rambling is trying to achieve).

    This should be ....well interesting. Floating and HIGHLY arbitrary mathematical abstractions used to possibly even more arbitrary assertions about the non-existence of gravity. Look, this is just nonsense and I suggest you drop it now : It contradicts hundreds of years of evidence , logic and so forth.

    I think first of all we should discuss the topic with open mind. when newton saw an apple fell from the tree he thaught there is some force that forced the apple to go down ward instead of going up he called this force gravity without giving any solid reason and logic because gravity was invisible and myesterious, people followed and started to worship the gravity and put this in all those matters that were unsolved.

  12. The idea of matter as a condensate of cosmic energy is not unwarranted per se (not certain that is a fair restatement of bukhari's conjecture, fwiw).

    However, what would cause the condensation? Are purely electrical forces, as are involved in a balloon floating in the wind rather than homing in on the Earth's center,

    A ballon that is filled with the hydrogen or methane gas go upward on the other hand a ballon filled with mouth air will always comes down .

    How will ynu justify this phenomena by electrical forces.

  14. Jupiters volume is over 1300 times greater than that of Earth, yet its only about 320 times as massive. Assuming Earth and Jupiter are suspended by buoyancy by the same "different gasses" "surrounding" them as you say, how do the "current" laws of motion explain their movement around the sun so precicely when their density is so vastly different?

    You should try taking a more inductive approach.

    As i said before sun and moon is revolving around the earth not the earth.

  15. Your saying that space isn't a vacuum, and has a bottom for these gases to rest on, right.

    No

    Actually in the begning whole the universe was just like a big ball then this big ball exploded and scattered into many different pieces like earth and other planets.From that day all the planets start to revolve around their axis and the sun and the moon start moving around the earth on their specified way till the end of the universe according to the 1st law of motion.

    By keeping in mind above basic theory every planet is surrounded by the envelop of different gases and in this envelop of gases these planets are suspended .Thats why when you go on the moon you can not walk on its surface because the moon is surrouded by gases are less dense than the earth.

  16. yes good point

    Whole the universe is surrounded by different gases.It can be understand by the following example

    If you put down a footbal or tenis ball on the surface of the water it will float on the surface of the water on the other hand if you put a steel ball on the surface of water it will sink down .

    Same is the case with earth and the moon all these are suspended in the universe according to their density and will never fuse or strike with each other.Thats why all the planets are moving and rotating in their orbits from the thousands of years.

  17. there is no gravitational force in this world if there any force exist then it would apply on the basis of their masses and weights.For example put a paper and a steel rod in front of a blower then switch on the blower you wil see the air will throw the paper many meter away from the blower on the other hand the steel rod will move some inches away from the blower.

    But in case of gravitaional force the result is reverse it works more effectively for heavier objects rather than light objects.For example if you put down a stone from the top of a building it will comes down on the ground very rapidly on the other hand if want to throw down a ballon it will never comes down on the ground if the gravity exist then the ballon should comes down more rapidly due to its lighter weight as compared to stone but it never happens because there is no force of gravity in this universe.Accuately there are two factors that are controlling the entire process

    1 density

    2 pressure

    Any object that is more dense than air will comes downward and the object less dense than air will go upward.The factor that controls the falling and upgoing speed of the object is the pressure of the air.

    There are many examples to support and prove this concept .
