The Unified Theory Electricity, Magnetism, Gravity , Mechanic
Both forces gravitational and electromagnetic fores are generated by similar With that change of view, Maxwell found the connection between electricity and. Gravity is so weak at the atomic and subatomic level because the masses of The static electric force between two charged bodies is given by. It's no contest: the electric force between these spheres is x . of the connection between electromagnetic and gravitational waves.
And last but not least, you asked the question "what is force? The physical quantity is measured by that change in momentum divided by the time it took to occur. So, kind of like how speed measures the change in distance over time, force measures the change in momentum over time.
I hope that satisfies at least some of your curiosities. Feel free to prod us with more questions! I'll take a crack at this too, in parallel with John's answer, since these philosophy issues aren't cut-and-dried. We seem to accept certain types of interactions strings pulling, hands pushing, These are interactions where the visible objects involved touch, i.
This feeling is captured in your language: When you think enough about it, though, such interactions are no more or less mysterious or explained than other interactions, such as between the earth and moon or between two magnets.
On a small enough scale, all of our descriptions turn into patterns of mathematical fields filling space- even those strings, and hands, etc. So our role here is in one way like what you're looking for- to eliminate the dualism between the familiar contact forces and the more abstract field-based forces. Unfortunately it's by converting the former into the latter, not vice-versa. If gravity and magnetism are not the same then why do they correlate to each other.
If one acts on the other and vise verse then they must be connected. Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass. I suspect gravity is a direct result of a magnetic field. If there is no atmosphere like on mars then the gravitational effect is weakened. Also the larger an object is regardless of the presence of a solid core the shear mass can distort the area around the object and induce a magnetic field, this in turn creates the effect of gravity.
James- Your question is close to many others, so I've marked it as a follow-up. In addition to the original question, you may be particularly interested in follow-ups 3, 8, and Just to recap some points: Gravity acts on everything, so it's not exactly surprising that it acts a little bit on magnetic fields.
It also acts on things with absolutely no magnetism. Gravity acts on everything, did I say that? There is no basis whatsoever for your other speculations about gravity and atmospheres and so forth. However, you have many co-thinkers. More philosophical questions about magnetism Q: Sorry to frustrate you with yet another repetition of earlier sentiments on this thread, but you still have not convinced me that magnetism is unrelated to gravity, undoubtedly due to my lack of scope in scientific knowledge.
However, why can't it be possible that 'magnetic' objects exhibit a greater amount of gravitational force than other objects. There are varying degrees of magnetism in magnetic bodies, and there are varying degrees of attraction in any bodies due to mass. Where do we make the distinction between a magnetic force, and a gravitational force. Gravity is present whatever the conditions, but what if magnetism isn't so much a force, but rather like a lens focusing or manipulating gravitational force?
The differing rates at which the supposedly distinct forces become weaker over distance could be explained by this 'lens' effect. For a continuation of my poor analogy, imagine focusing sunlight on an object with a magnifying glass. Sunlight is hitting the object regardless, but with a magnifying glass, you can focus the sunlight into a beam.
In this analogy, the regular sunlight is gravity, and the lens is magnetism. I oppologise if you find my ignorance of science irritating, but the common man thinks about these things too: I'm not irritated at all.
I'm glad that you're representing a very widespread view. I'm still puzzled about the motivation. We have nice complete theories of electromagnetism and gravity.
OK, the quantum version of gravity isn't complete, but for our purposes here plain old Newtonian gravity and Maxwell's EandM suffice. Gravity is NOT magnetism Q: Magnet and gravity r the same? Does a magnet just have gravity captured inside it?
I have not read all of this yet but there is something here. Is gravity created by spinning something and the faster the spin the more gravity there is or resistance on an object, like a motor? If you read the earlier posts, you'll see we say the opposite: The effect of spinning on gravity is very small.
In fact, it was just in the last few months that the Gravity Probe B experiment was able to measure the tiny effects of the Earth's spin on its gravity. I heard a crazy and strange theory that i have not been able to exactly prove wrong.
Its called the Hollow Earth Theory, Theory that there are large holes at each pole and a small star inside our planet with the inside reflecting the planet outside.
First off any proof against this i found are just photos of Earth so i looked up a photo of Earth on nasa. Could just be my eyes but the ice looks offish and slightly off color at the north pole where a giant hole would be. However, his conviction remained: Today, there are a number of scholars pursuing this obvious line of inquiry. After all, the electrical and gravitational forces share fundamental characteristics—they both diminish with the inverse square of the distance; they are both proportional to the product of the interacting masses or charges; and both forces act along the line between them.
Matter and mass Gravity acts in proportion to the mass of an object. When it was found that atoms are composed of charged particles, there were attempts to explain mass in terms of electromagnetism.
However, it is not the philosophical concept of mass but its mathematical treatment that occupies physicists. The consequences are profound for cosmology. The mass of a celestial body cannot tell us about its composition. We cannot say what the Sun is made from!
Another example is comet nuclei, which are electrically charged bodies. They register masses that should have them constructed like an empty sponge yet they look like solid rock. It is their appearance, together with the recently recovered high-temperature minerals rock particles from a comet, that give the accurate picture.
Comets and asteroids are fragments of planets. They are not primordial—quite the reverse, in fact. This inexcusable philosophical muddle over matter and mass has given rise to violation of the fundamental physics principle of no creation or annihilation of matter. The simple fact is that we have no concept of why matter manifests with mass. But when we apply force to a body, how is that force transferred to overcome inertia?
The equivalence of inertial and gravitational mass strongly suggests that the force of gravity is a manifestation of the electric force. The origin of mass in the electrical nature of matter.
Ralph Sansbury in New York. Simply stated, all subatomic particles, including the electron, are resonant systems of orbiting smaller electric charges of opposite polarity that sum to the charge on that particle. In this model, the electron cannot be treated like a fundamental, point-like particle. The transfer of energy between the subtrons in their orbits within the classical electron radius must be resonant and near instantaneous for the electron to be a stable particle.
The same argument applies to the proton, the neutron, and, as we shall see —the neutrino. It is ironic that such a model requires the electric force between the charges to operate incomparably faster than the speed of light in order that the electron remain a coherent particle.
A recent experiment verifies this. Electromagnetic waves are far too slow to be the only means of signalling in an immense universe. Gravity requires the near-instantaneous character of the electric force to form stable systems like our solar system and spiral galaxies. We must have a workable concept of the structure of matter that satisfies the observation that the inertial and gravitational masses of an object are equivalent. When we accelerate electrons or protons in an electromagnetic field they become less responsive to the fields the more they are accelerated.
This has been interpreted as an increase in particle mass, which is unhelpful until we understand the origin of mass. If the charged subtrons have little intrinsic mass, how do they, in combination, give the electron, proton and neutron the property of mass? An electric field will transversely squash the subtron orbits within an electron or proton. If you cause acceleration at one point in a circular orbit and a deceleration at the diametrically opposite point of the orbit, the result is an elliptical orbit.
In the case of an accelerated particle, the orbit will tend to flatten in the direction of the applied force. It seems that as more energy is supplied to accelerate the particle, the more that energy is assimilated inelastically in further distortion rather than in acceleration.
Is there any relationship between Gravity and Electromagnetism? - Physics Stack Exchange
In other words, the electric force becomes less and less effective at acceleration, which Einstein would have us interpret as an increase in mass. That allows the proton to distort more readily than an electron in the same electric field and may account for their classical differences in size and mass. The result is that the dipole-dipole force, which varies inversely as the fourth power between co-linear dipoles, becomes the familiar inverse square force of gravity for extended bodies.
The gravitational and inertial response of matter can be seen to be due to an identical cause. The puzzling extreme weakness of gravity one thousand trillion trillion trillion trillion times less than the electrostatic force is a measure of the minute distortion of subatomic particles in a gravitational field. In this case, the system is placed in a situation where quantum mechanical effects are to be expected. Chiao proposes to levitate such drops in a superconducting magnetic trap at ultra-low milli-kelvin temperatures and use them as transducers between gravitational and electromagnetic radiation.
He suggests that electrically driving pairs of such drops by scattering microwaves from them should produce gravity waves of the same frequency as the microwaves, and that when illuminated with the resulting gravitational radiation, the drops should produce electromagnetic waves of the same microwave frequency.
Using this viewpoint as a model, he calculates the probability of "scattering" microwaves into gravity waves and vice versa. Chiao concludes that, provided the drops are separated by a distance comparable to the wavelength of the waves, the probability is large enough to be well within the range of experimental measurements.
This suggests an experiment similar to that of Heinrich Hertz, in which he produced and detected radio waves across a distance of a few meters. At UC Merced, Chiao and his co-workers are currently building Hertz-like experimental apparatus to demonstrate generation and detection of gravity waves.
This work points to at least two applications. The first is the implementation of a "gravitational radio", a device that can send and receive signals in the microwave frequency domain using gravity waves. The other is a plan to attempt the detection of primordial gravity waves left over from the early stages of the Big Bang.
Let us consider these one at a time.
Electrical waves radio waves, light, x-rays, gamma rays interact strongly with matter, while gravity waves pass through matter almost as if it was not present. Thus, an ensemble of levitated charged drops on one side of the Earth might be able to transmit gravity wave signals right through the Earth, to be detected on the other side by a similar ensemble of levitated charged drops.
Moreover, secret or private messages sent by gravity waves could only be detected with levitated charged drop receivers tuned to the correct wavelengths, providing, at least for a time, a non-interceptible message channel. Chaio and his group are beginning such experiments at the University of California at Merced.
They are placing a transmitter and receiver close together but carefully screened with Faraday cages to suppress electromagnetic waves.Electric and Gravitational Forces
The other application perhaps requires some explanation. In the early stages of the Big Bang, the Standard Model with inflation predicts that a large amount of gravitational radiation was created, with frequencies ranging from Hz to Hz. The ekpyrotic model of Steinhart and Turock see my AV Column "The New Recycling Universe" in the November issue of Analogon the other hand, predict that when extra-dimensional branes clap together to start the Big Bang, there is considerably less gravitational radiation, with what there is concentrated at frequencies between 1.
There is a third pre-Big-Bang model that predicts even more gravitational radiation than inflation, and that radiation is concentrated at frequencies between and Hz. With presently available technology, distinguishing between these models is very difficult, because gravitational radiation has not, at this writing, ever been directly detected.
The cosmic gravitational radiation is considerably weaker than that from merging neutron stars and would be even harder to detect. There is some hope that the primordial gravity waves may be indirectly detected because they "write" on the primordial electromagnetic waves that were created later in the Big Bang. Therefore, second-generation probes of the cosmic microwave background radiation may be able to observe correlated structures in the polarization of the microwaves arising from very low frequency Hz gravity waves produced in the era of Big Bang inflation.
However, these are very difficult measurements, and no such observations have as yet been reported. On the other hand, if Chiao's technique can be made to work, it offers the possibility of direct detection of primordial gravity waves.
