I know this is probably a stupid one here.. But like, isn’t light just photons bouncing around? My lightbulb is firing these photons out when it’s switched on but presumably it’s not sucking them back in when it’s off?
So where da light go?
Also shouldn’t it get brighter the longer the light source is on as there’s more photons?
Where are they all going?

This is not a bad question at all, I used to ask this to myself all the time when I was a kid, when I didn’t even know what photons were, so it was even harder to understand.
So imagine you’re fitting a gun. The gun being the source is light and the bullets being the photons. Let’s just assume for the sake of this example that the bullets travel for ever, till the end of the universe.
So if you stop firing (like switching a light bulb off), the bullets keep travelling. Your firing or not doing so doesn’t effect the bullets.
And just like bullets from a gun, even photons are released with a momentum, so they also never stop.
