If I understand it correctly, we measure time by how fast light passes, or something similar to that. Now if the universe expands faster than the speed of light, would that mean that the universe ages faster than earth, or maybe slower than earth? Maybe this doesn’t make sense but I have a gut feeling that there’s something to it…

Everyone is at rest from their own point of view.
We see distant galaxies receding from us at breakneck speed. But to aliens living there, we are the ones receding from them at breakneck speed.
Time passes at the rate of one second per second for them too.
Now, if we were to, with a magically powerful telescope, observe an alien clock, from Earth, we would see it ticking slow. It would appear to us that they are stuck in slowmo. But we appear that way to them too. If we got into a ship, and boosted at almost the speed of light, and got all the way there, billions of years later (but it would appear to us, the travellers as only a couple weeks), we’d experience time just as we had on Earth, one second per second. Just as we did in the ship. Local time is always one second per second.
