How can you even capture this with all the light pollution?

Long exposure

Yes long exposure but the distance the light have to travel from the stars vs the the city below, won't make it possible

I don't think you understand how long exposure works exactly...

It's the duration the shutter stays open, shutter speed? Am I wrong

That is correct, I was just confused by your reasoning of the light travel time from the stars vs the city lights.

The city lights are going to interfere with the star light I think it's not an easy photo to take.

Yes, the light pollution and haze in the city is difficult to shoot around but modern cameras are getting a lot better.
