Can gravity be replicated through  any  scientific process or lab conditions ?

I think it is more accurate to say we can easily replicate the EFFECTS of gravity, rather than gravity itself.  Gravity relies on mass.  More mass, more gravity.  Any "replication" of real gravity is not replication it is the real thing.

Newton just claimed that was true.  We have made millions of measurements which support the theory.  But I know no way of proving it.  A separate question is whether inertial mass equals gravitational mass.  Again, all the measurements we've ever taken support the idea, but we know no way to prove it.

It is possible by a process called distillation where the mixture is slowly warmed n the outcoming gases are cooled and collected but I am not sure that it will work out with common laboratory apparatuses.

Nobody really knows.  Einstein's special theory of relativity posits gravity as a warp of space-time caused by the object's mass, but that only pushes the question one layer further down.  All we know for sure is that gravity exists, is pervasive, and can be important.

Yes, especially forward at a rate of 1 sec = 1 sec.\n\nI also believe that other rates are possible depending on velocity and proximity to sources of gravity.\n\nI also would like to believe that it can be reversed, but that's harder to swallow due to paradox effects.

What you're describing is called the 'grand unified theory,' or GUT. There are four known fundamental forces in nature that literally control everything--gravity, electromagnetism, the weak nuclear force, and the strong nuclear force. Science has been successful in uniting all of these except gravity.

It is absolutely possible and does happen!  There is always an equilibrium that is reached between the gravitational pull on the solutes and the random forces exerted by the solvent molecules.  \n\nYou may recall the famous Meselson-Stahl experiment.  They proved the semi-conservative theory of DNA replication by separating strands of DNA according to density.  They loaded the DNA (some of which was doped with heavy nitrogen) into centrifuge tubes filled with a cesium chloride (CsCl) solution. Cesium has an atomic mass of 132.9g/mol, its a very heavy atom.  When they spun the tubes the CsCl would become more concentrated near the bottom of the tube and create a density gradient.  The different strands of DNA would then migrate to the different regions of the tube where they were more or less neutrally buoyant.  since the centrifugal force is equivalent to a gravitational force they would both create a density gradient.\n\nIn addition, when I took analytic chemistry we were always reminded to shake our standardized solutions so that the concentration would be truly uniform.

These answers are correct, in that inertia is only present during acceleration.   This is why countless designs to create gravity-like conditions on spacecraft don't work, because they try basing them on acceleration, which will not work when objects inside the craft appose each other in any way...IE, a person moves.  Now to get to what humans are confused about.  Gravity is not a force at all, but simply the consequence of the local slope of the universe, in a direction the human eye cannot see: time.  You stick to the floor not because gravity is pulling you down, but because that is the shortest distance between today and tomorrow.  In the mid 1950s, the Manhattan project had has its goals to crack the anti-gravity mystery.  Many publications were abundant during the early 50's.  By 1957, it completely stopped.  The Kinemassic Force field generator is probably the most known and only accepted anti-gravity generator ever created by humans.  This design has been arrived at by several scientists in the last 10 years.  When charged, the generator creates a gravitational field that is non-magnetic based.  Uses include artificial gravity, and propulsion.  This methodology is likely the future of space travel, and also disproves the Newtonian view of gravity in the universe.

I'm interested in what kind of answers you'll get to this question.  The fact of the matter is, no one really knows what gravity is or where it gets it's energy from.  One of the few things that are known about gravity is that it is not effect by space and time like light.

In theoretical work, such as theoretical physics and cosmology, researchers are limited to mathematical proofs. Occasionally an experiment may be performed or an observation may be made that indirectly strengthen or weaken a theoretical hypothesis.\n\nEinstine did not live long enough to see all of his theories tested..one of them is being tested right now using the most spherical balls ever made. They have been launched into orbit and will hopefully tell us more about gravity and space.

As far as I know, they are still not sure as to what creates gravitational force. If they determine the source, one might negate it to experience zero gravity anywhere.

Current knowledge is that we still don't know what gravity is. Curent ideas derived from quantum physics (M-theory, string theory) is that gravity may be a "field" whereas other ideas believe gravity to be a FUNDAMENTAL constituent of the universe. Others think that it may be able to permeate our universe's brane (if it exists) into other branes and possibly other universes or "dimensions".\n\nFurthermore, there is evidence that gravity, may in fact, be a repulsive force rather than an attractive force (Hubble - universal expansion).\n\nHowever, never rule anything as impossible - especially on the quantum scale. Quantum reality is much more bizarre than human experience.

No, A BIG NO. even on outer space, the gravity is NOT zero. It is very near to Zero (maybe like 0.0000000000000000000001 or something), but never exactly zero. This is because gravity has a range of infinite, i.e. the effect of gravity reaches to every place in the universe and even more. However, it is also known that gravity's power is inverse square to the range (S/4*pi*a_huge_distance^2 = almost 0, but never exactly 0, unless S=0 which means there is no gravity source), thus after a certain distance, the effect of the gravity is negligible and won't affect almost anything. BUT it is not zero. There is no point in space that have completely zero gravity, if there is at least one gravity source in that space, even if the gravity source is placed very far away from that point or even if the gravity's power is very small.\n\nThe gravity is similar to light in this way of infinite range. If you fire an ideal laser (one that would not spread out even minutely after great distances), and you stand on a very far away point from the laser, you'd still be able to be pointed by the laser. Light is also a force that have an infinite distance. Light however, is not exactly the same as gravity.

The condition for a scientific experiment is its repeatability. Therefore, your question is not so correct....\n\nI think you wanted to question the repeatability of experiments. Then, in my opinion, nothing is completely repeatable since the time coordinate of experiment has been passed forever, and we face a new experiment each time.

Extremely little. The Gravity in Newtonian Physics is determined by the mass of the body which is not effected by the state of the matter only its net mass.\n\nHowever in General Relativity not only the mass but the pressure is involved. So in General Relativity increased positive pressure does very slightly increase the gravity. But this added amount is usually very insignificant for most bodies due to the fact that these pressures are extremely small relative to the speed of light.

no. \nthe stress-energy tensor tells us how the energy is spread, and moves, across spacetime.\nthe gravitational constant is a parameter that determines to what degree 1 kg of mass (for instance) will "warp" the spacetime. \n\nso, you can't derive it from the einstein equation.\n\nin fact, relativists usually set the gravitational constant to = 1, so that they don't have to deal with it. although it's essential when you're trying to determine exactly what your physical predictions will be, it's not really an active element of einstein's theory. it just kind of sits there.

There is currently no porperly accepted quantum theory of gravity. \n\nSome candidate theories include the graviton as the exchange particle that would carry the gravitational force. Gravity has a very special role in physics because it act on everything, and so effectively shapes space-time. A quantum theory of gravity has to allow for the graviton to interact with every other particle, including the other force carrying particles, which would be unique behaviour.\n\nThe classical theory of gravity is that it operates by curving space-time (the theory of General Relativity which, contrary to what you may expect, is classical physics). General relativity is smooth down to the smallest scale, unlike quantum mechanics.
