    Gravity doesn't exist, it's just taught because that's an easy way to visualize it.

    Objects are pulled towards other objects depending on mass and range, it's just how the world works. There is no force causing it, it is in an object's nature.

    The whole theory that distortions in SpaceTime cause gravity is false and flawed, for even if it was distorted, objects would stay in the same place if gravity was the only force acting on them.

    And you know this how....? If you're going to make such a claim, provide some back-up.

    That point does not stand unless you also provide back-up for your claims.

    No, you can easily look up space time and gravity for yourself. I was merely explaining it in another way so that it would be easier to comprehend.

    Space time, disprove it.

    Spacetime is real.

    Gravity being caused by it is not.

    Gravity is a force caused by the pull objects exert on eachother the more mass an object has the greater the pull (gravity) I thought this waas a well known fact.

    Objects fall towards other objects, the easiest way to teach it is there's some force governing it.

    Both objects fall towards each other, the greater an object's mass and the closer the other object is, the stronger the pull.

    There is no reason. It just happens.

    you cant truly explain gravity because the grand united theory hasnt been formed properly because we need the higgs boson. (mass giving particle)
    if that doesnt exist, we're ****ed, to put it bluntly

    Gravity is the explanation for the tendency of objects to be attracted to other objects. It is a law of physics, it exists and the name gravity was created to explain it.

    At the current moment we cannot explain why it happens but we know it does, and we also can predict gravity's force by using mass and distance to calculate its effect.

    O_o Wt Heck? That is not gravity? Thats the Law of attraction. Also known as static cling.

    Gravity is not.. the relationship of an object in comparison to its size. Gravity, is the relationship of something to its MASS. HUGE difference. Ill use an OLD tale to make you understand the diff:

    What weighs more? a pound of feathers? or a pound of Gold?
    Answer: same weight.

    What has a larger mass: a cubic foot of gold, or a cubic foot of feathers?
    Answer: Gold

    "In everyday usage, mass is often taken to mean weight, but care should be taken to distinguish between the two terms in scientific use, as they actually refer to different properties."

    In this case with these amounts, Gold is denser, and therefore would have a larger mass, and attractive pull on any object than the feathers. This pull has been defined to be gravity. All currently discovered sub-atomic particles, even though some are tiny [this INCLUDES electrons] have mass, and therefore are effected by gravity. They pull on each other, but that is not the law of attraction; Ones' gravity is simply greater than another. That is why the moon orbits us, and both of us orbit the sun; that is why some solar systems with Binary Stars sometimes revolve around each other perfectly, elliptically, or around a common share of mass, or centre of mass. Its where the gravity of each other pulls, and once both sides cancel, where the middle is.
    Also, gravity has absolutely NOTHING to do with magnetic forces: magnetic pulls rely on positive and negative charges and relative material. If gravity WAS based on this, a Neutron Star would not be affected by gravity at ALL, because its composed of neutrally charged components. For the record, a neutron star is RIDICULOUSLY dense, and the beginnings of a black hole. Therefore, a huge gravitational effect >_<. Magnetic pulls EFFECT gravity, but do not cause it. they can cause an object to have and increased or decreased fall, depending on its charge and the charge of the object it is falling into.
    So what if you had a giant box fill with neutrons in space >_> AKA neutron star [^look above^]
    Up to the last chunk of the first section and your second quote you were starting to sound intelligent. then i almost smashed my face into the screen.
    Thats all relative. If you have an object, Just one single composed massive object in the WHOLE universe, and only its forces were acting upon it, then yeah, you'd be right. but all theories and laws are based off the ending results of two objects interactions with one another. the same works with politics >_> If only ONE man was alive, then he would live by his rules. with a population, we have to find a set of agreed rules to live by.

    Everything happens for a reason. If we are unable to explain it as of now, that doesn't mean "it just happens".

    ...I think that's all for now.

    I looked up gravity in the dictionary and it said

    So yes gravity is a force of attraction between objects.

    But on Earth we cannot feel the attraction to objects because the effect is miniscule compared to the Earth's gravity.

    Also, static cling has do with Van der Waals forces between positive and negative ions that are attached to an object.


    Mass vs Weight

    Mass=the amount of matter in an object

    Weight=the effect of gravity on an object.

    They are hardly related at all. For example, an objects mass is constant, but weight changes with location, so if you go on the moon, your weight is about 1/6 your weight on Earth because the moon has about 1/6 the gravity. Hope this helps.

    BAHAHahh I know they are hardly related? I extremely pointed out the difference with the two links. For the record, Dictionary s have their definitions edified and changed constantly. A dictionary is not a scientifically location of termenology. Its a basic explaininer. And the def even further showed that gravity is replated to matter and the attractive foreces of it. not attraction of objects. the Denser the matter, the larger the attraction.

    For the record, im pretty sure that dictionaries do NOT change their definitions, and if so, then there is nowhere to look to define it except an encyclopedia, which are all outdated, and the internet hardly counts as a resource do the the fact that anyone can write something and put it on the internet.

    For the mass vs weight, i was clarifying what they actually are, and i agreed with you, so no need for rebuttal. i just stated what they actually are defined as.

    An object is composed of its mass, and gravity affects that combination of mass as a whole, so yes, it is a force of attraction between objects BECAUSE it is a force of attraction between mass.

    Things do just happen.
    Otherwise, there would've either been no world at all or time and space wouldn't have "begun", but would be eternal.

    I think you're saying something similar to what I'm saying, that there isn't a "force" as such, but objects do it by nature (objects are attracted to other objects, there isn't a force pulling them together, they just go towards each other naturally).

    You have absolutely no idea what you are talking about.
