Okay, thanks

Um, I think I might have an idea on what gravity is. I'm not very experienced at physics and stuff, as I'm only in 7th grade, so I was looking up my theory and came across this website, so I decided to post it on here and see what everybody says. Okay, so here it is: If everything in the universe was continuously growing, expanding, and accelerating, could that be the cause of gravity? Like if you had a balloon, and you blew it up at just the right speed and kept blowing it up faster and faster, if you put something on the balloon, wouldn't it stay there, as the balloon would be pushing against it as it, (the balloon,) accelerated? Please let me know it there is anything that would not be possible about this theory. Thanks! -PacMan3456
