First: I think Universe Sandbox is awesome, but today i downloaded the update and tried it out and there is one major...you can't really call it a bug, but in my eyes it is...

Why can you make a light pulse with a black hole... This wouldn't be possible if it would be realistic.
I mean, actually light gets like...."eaten" by a black hole, doesn't it...

It's more an option to see the speed of light, not the movement of light expelled of the object. I see this like an option, not a realistic possibility.

Good point. You're right that a black hole should eat the light particles. I think the light particles are immune from the gravity of the source object for a few seconds after creation (but can't remember exactly how I set it up, I'd have to check).

The light particles are effected by gravity, however. You could create two super massive objects, lock their positions, slow the time step way down, and then emit light pulses from either and see how the light is effected.
