They fall all the time around the centre of the galaxy. Because they have a speed along the circle, they end up moving around the centre of the galaxy, and not falling into it. It’s the same phenomenon of the Moon falling on the Earth all the time, but yet never falling on Earth.

If you’re asking whether the points of light you see in the sky will ever fall out of the sky and hit the ground, then no. Those points of light – stars – are actually amazingly, mind-bogglingly big, it’s just they’re a very VERY long way away, so look like tiny points of light here on the Earth! There’s no way a star could ever get so close to us that it would fall to the ground 😯

Sure, if the star ends up next to something even heavier than it, like a big black hole, then the star will fall in!
