Gravity

[Paul Singh Jr]

Because sound waves have anti gravity properties is it possible to vibrate a object at a frequency to give it anti gravity properties 

[Endy0816]

Not true Antigravity but there is acoustic levitation.

What about if you used a resonating frequency tuned to the opposite wavelength of the naturally occurring gravity field

I am not aware of a gravity field having a wavelength, what do you mean by that statement?  

All gravity fields are naturally occurring....

Sound is not a gravitational interaction, so it can't have antigravity properties.

No.

Endy0816 showed acoustic levitation. We also have mechanical levitation (i.e. standing up, using stairs or an elevator, etc.) We can use air, too - planes and helicopters. It always involves a non-gravitational force that equals or exceeds the gravitational one. From there, application of Newton's second law of motion.

But isn’t gravity basically a magnetic field 

Would the same principle apply

Why does heavier gravitational force only exist around stars planets an asteroid

It doesn't

Newtonian gravity depends on the mass of the body, so larger masses will have stronger gravity at the same separation.

But gravity has been measured for much less massive objects than asteroids., so it's not true that it only exists around stars, planets and asteroids.

Magnetic fields have polarity. You have a North and South pole. Like poles repel each other and unlike poles attract.

The poles always occur in pairs (a magnet will always have both North and South poles)

Because of this, it is possible to arrange the poles in such a way that all the poles cancel each other out and you get no net attraction or repulsion.

Gravitational fields have no polarity.  They are purely attractive; mass attracts mass.  The more mass, the greater the attraction. There is no way to arrange things to get a repulsion or cancellation.

But, compared to magnetic fields, gravity is very weak, and it take a considerable amount of mass for this attraction to be easily measured.

But, as swansont has already noted, we have measured gravitational attraction between relatively small masses.

The earliest such measurement was done by Henry Cavendish in 1797.

He took two brass* spheres which were placed on the ends of a long rod which, in turn, was hung from a piano wire at its midpoint.  Two more larger Brass spheres were placed near the suspended spheres so that any attraction between them would rotate the rod and twist the piano wire. Then, by measuring how much rod rotated, and knowing how much torque it would take to twist the wire by that amount, he could work out just how much force was attracting the spheres to each other.  And since he also knew the mass of the spheres, he was able to derive the constant of proportionality for gravity.

This, in turn allowed him to work out the mass of the Earth.  Up until then, while we could measure how much gravitational force there was between the Earth and an object of a known mass, and we knew how far the object was from the center of the Earth, we were still left with two unknowns: the mass of the Earth, and the gravitational constant of proportionality.  Knowing either one would allow us to work out the other.  

Cavendish's experiment gave us the value of the gravitational constant, which meant he could now calculate the Earth's mass. Because of this, Cavendish has been referred to as "The man who weighed the Earth".

 

*he used brass as it had no magnetic properties that could have skewed the results.

One other thing - magnetic dipole fields drop off as 1/r^3, while gravity drops off as 1/r^2, so even if you could get a solar system to work (you can't have everything attract, as Janus pointed out), it doesn't follow the pattern we see — the planets and moons etc. follow a 1/r^2 attraction.

Maybe it’s because theres different types of gravity

There aren’t. Anyone familiar with physics would know this.

And if you are suggesting some new physics, this falls spectacularly short of the requirement to present a model or some kind of evidence.

Most of  the stuff you have been told are facts, rather then myth.

Several of your posts are assertions. If you stick to asking questions, there isn’t a problem. But e.g. “Because sound waves have anti gravity properties” is not a question
