can anyone tell me is it the galaxy rotating or the camera??

i need help

currently in a debate right now any help would be appreciated

thanks in advance :)

Galaxy's rotate due to gravity like everything else in the universe. Although I doubt its that visually fast.

thanks for reply
i was debating with a guy because galaxies take around million of year to visibly rotate and people think broly busted it
but he said thats not galaxy rotating its the camera
