Dear all,
i'm very new to cosmology/astronomy branches of physics.
i've one simple question.
it's known that the universe is expanding and i suppose the measurement was made by Hubble for which he won the nobel prize.
but also, i recently learned that there're black holes at the centre of galaxies like milky way.
if that's true, the black holes shud be 'sucking' in the other celestial bodies, won't they?
in this case, considering there are many black holes spread across the universe, isn't it cotradictory to the fact of 'expanding universe' ?
could someone explain?
thanks.
