    This is an open argument about gravity.i just want to see how the wonderful minds here see this phenomenon.


    why does gravity seem stronger at atomic level and much weaker with matter?






    Whatever you guyz say here, i would love to think that this gravity stuff has something to do with the expansion of the universe accelerating instead of slowing...and i also think it really explains why the inflation was well after the recombination.(its one of my possible theories which i think can explain the above.but i don't think its time i make it an argument.)





    what makes gravity like this is the question..

    Why do you think gravity is stronger at the atomic level? There are other forces besides gravity, like electromagnetic, which are much stronger.

    i don't think it is stronger....scientist said it is..
    with that i know its stronger.


    if you doubt make your own research on it

    Sorry, you are going to have to tell us where a scientist said gravity is stronger at the atomic level, to understand what you mean. Gravity is the weakest of the forces.

    Also, recombination occurred roughly 370,000 years AFTER inflation, if you are referring to the early inflationary epoch. After the inflationary epoch (which occurred within the first second) we have around 7 - 8 billion years of decelerating expansion followed by 5 - 6 billion years of accelerating expansion.

    I also have to question this. Gravity is proportional to mass. At the scale of an atom, it becomes insignificant, compared to other forces. Why do you think it is stronger?

    It is a question of domains. Within an atom there is very little mass, so the other forces have much more of an effect. Within, say, the solar system there is a lot of mass, so gravity plays an overwhelmingly strong role. On the other hand there is little net electric charge, so electromagnetism doesn't weigh in much, and the strong and weak forces are out of the question altogether because they have limited range.
