Hi guys! I would like to start this discussion by saying I am brand new to this site, so if you could, please go a little easy on me. I am also only 17 years old, so I can say I do not have much experience in the study of physics, but I do love it very much and am very curious and eager to learn more. First, let me share with you something I've learned and have questioned. We all know of the existence of gravity and that it is a force that causes two particles to pull towards each other. But if gravity is a force, then, according to the Standard Model, it must also have its own accompanying particle, which, in question, is called the graviton. These are tiny, massless particles that are somehow able to push and pull every bit of matter in the universe. But, what has gotten me so interested in the graviton is, it can do this while being very weak on the planetary scale yet strong in relation to something such as two positively charged protons. So, my question is, why does it act differently on planets versus elementary particles? I know this a question that may not be able to have a for sure correct answer, but I have just been curious to know what your theories are. Please, anyone is welcome to answer. P.S. Pardon my high school grammar and punctuation.
