RE: About my own research: gluons, gluinos and sgluons are not weird creatures from Harry Potter
Gravity starts to be important at energy scales billions of billions of time higher than at the LHC. Therefore, we still have a long way to go to get there (I am not even sure this will be ever manageable). This being said, researchers are already trying to build theories that would work at these scales (quantum gravity for instance).
I am not sure to have understood the last part of your comment. Sorry ;)
So we'd need some sort of galaxy-sized ultra large collider? Heh.
Oh, I don't understand any of it either, I guess I was just saying that it must be some other forces that are causing the numbers discrepancies between real and expected values.
Something like that :D
Well not necessarily. First, this could just be statistics. Then, it could be other particles not related to new forces, and so on. There are many possible reasons behind some apparent excess or deficit. A human error being one of them ;)
its just gravity is weak compared to whatever makes particles stick together (in short as i came to understand it) so they don't really study it as such at quantum level, its more like a cosmology / astrophysics thing (dont bash me on semantics, im a very un-educated person :))
No, at least based on my limited understanding I think you are correct in what you've said.
o dear
beware my exploding ego now :p
Hahaha
True!
Gravity is both negligible at the level of the elementary particles and does not work at the quantum level. But since any effect would be invisible, it is fine :)
is gravity actually 'known' ? i mean not like defined like time , but is it understood like do you know what causes it , where it originates from ?
The strength of the gravitational interaction is known. From that, we know that whatever is its exact form at the fundamental level, the effect is roughly 0. What do you mean by "originate from"?
well if electricity comes from electrons and light from fotons, so to speak, where does gravity come from ?
Electricity comes from the motion of electric charges. The corresponding fundamental interactions behind this phenomenon is electromagnetism that is modeled, at the most fundamental level, by photon exchanges between charges particles. We can correspondingly assume a graviton exchange for modeling gravity at the most fundamental level. However, the formalism does not work. Which is why the embedding of gravity in elementary physics consists in one of the present challenges.
allow me to be the layman for once and ever
do gravitons exist
i mean have they been confirmed, observed and detected ?
has anyone "seen" them ?
i know i have obnoxious questions but ... its a bit what i do , like me
is there any proof of a "graviton" as such ? or are they just part of the mathematical model ?
