    Well as with most things in the universe there seems to be an opposite to everything, I'm pretty sure we haven't seen the Gravaton yet but an Anti-Gravaton has to be out there somewhere.

    What I am wondering about is what an anti-gravaton does? Attraction,repel or destruction of a gravaton?

    Is there some study on this somewhere?

    Like the photon, if the graviton exists it is expected to be its own antiparticle.

    Well I've never heard of a photon stopping unless it runs into something ... and I suppose neither does gravity until Dark energy came into it ... Imagine if Dark Energy was Anti Gravity, that would mean that all those the universe is gonna fly apart in a few billion years guys were wrong

    Write a similar technical means to implement anti-gravity possible. This technical tool will be modified to the metric space with the built-zhativany. Zhativana will be based on a built engine, based on the energy space. The energy space is infinite and such technology could ever overcome gravity. However, this device will be created in a relatively late future. At the beginning of the XXI century it is impossible to create.

    New Hypotheses and Ideas > Dark energy, Dark matter, Fine tuning problem, Negative mass!

    http://www.thescienceforum.com/Dark-...%21-21177t.php


    [ Abstract ]

    From the observance of the HSS team in 1998, they gained the mass density of the negative( Ω_M = -0.38( 0.22)), using field equations which do not have the cosmological constant.

    The quantity of the mass couldn't be negative value in they thought, the value is trashed away.
    We have to know that not the field equation has disposed the value, but our thought disposed that value.

    In the world of positive mass, ground state is a point that energy is low, but in case of negative mass, ground state is a point that energy is the highest.

    Accordingly, in the world of negative mass, energy level is filled from the highest to the lowest, and stable state means the highest energy state, so the catastrophe to energy level of minus infinity never happens even if negative mass spontaneously emits energy.

    Assuming that negative mass exists, Newton's Law of motion was derived in between negative and positive masses and also between negative and negative masses.

    As a method for proving the existence of negative mass, an explanation on the revolution velocity of the galaxy through negative mass has been presented. In this process, the existence of spherical mass distribution was given; furthermore, explanation was done using this, to show observation results where dark matter effect through negative mass is proportional to distance r.

    If Ω_M is -0.38, universe's age is 14.225 Gyr. It is in the range estimated by other observations.


    Assuming that negative mass and positive mass were born together at the beginning of universe, it satisfies the various problems that previous dark matter and dark energy possess, such as,

    [ Dark matter ]
    - Centripetal force effects of galaxy and galaxy clusters from previous dark matters,
    - Mass effects that is proportional to the distance r,
    - Low interaction between dark matter when collision occurs between dark matter.

    [ Dark energy ]
    : Repulsive force needed for expansion, dark energy that has positive values,

    [ Fine tuning problem of mass density ]
    : The reason of that mass density close to the critical mass density.

    [ Cosmological Constant Problem ]
    - The reason of that dark energy seems to has a small and non-zero value.
    - Phase transition problem of dark energy

    [ Others ]
    - Collision of Bullet cluster,
    - Deceleration expansion and acceleration expansion of universe,
    - Age of the universe with negative mass density
    - Size of the universe

    [ Proof of that observed dark energy value ]
    : Dark energy observation value ()


    As a result, the necessity of observation focusing on exact computation and detection of negative mass is stated.

    Like the photon, if the graviton exists it is expected to be its own antiparticle.
    If it is its own anti-particle, then shouldn't constructive and destructive interference be possible?

    Is that what's happening when two gravitational fields pull with equal magnitude in opposite directions, or should another kind of constructive/destructive interference also be possible?

    Being its own antiparticle has nothing to do we constructive and destructive interference. This is due to the wave nature of the particle. For instance electrons display constructive and destructive interference when a beam is passed through a diffraction grid.

    Do not confuse gravitons (the quanta of gravitational radiation) with the gravitational field. Gravitons would fulfill the same function in gravity theory as photons do in electromagnetic theory.

    In electromagnetic theory it is virtual photons that mediate the field. Likewise, it is virtual gravitons that would mediate the gravitational field.

    Gravitons themselves no more attract masses than shining a flashlight on a hunk of iron will attract it.

    So is a graviton a particle in the sense that it would behave like electrons do, and be able to exhibit interference under some circumstances?

    I see what you're saying, though, that interference patterns are a property of all particles, not just particles that serve as their own anti-particles. Now, what makes us so confident that light has no anti-particle? Is it the fact it has no net charge?

    Well I am not willing to give negative mass its own particle, it really does mess with too many Equation.

    It being its own anti-particle is a bit of a shortcut to explaing it. I will admit to being a bit bias towards gravity seeing as something that has been constantly prodcing energy since the begining of time, you have to give that some respect.

    But if you do have an equation that says its about a 3:1 anti-particle ratio I would love that or any ratio below lol :P (not 1:1)

    I am begining to think that about all 3 properties that I mentioned in my first post may be true to some degree. Attracted and destroyed by a graviton and repelled by matter, ofcourse I know there would have to be an outside source or something in matter that creates graviton and anti-gravitons.

    Prehaps I am getting too caught up in Dark energy :P
