I'm seeing quite a few physicsy questions. Are they on topic here?

Examples:

If nothing travels at the speed of light, except light, how can a black hole also pull light into itself?

https://astronomy.stackexchange.com/questions/69/does-e-equals-mc-squared-apply-to-a-black-hole

Do all the objects in the universe exert force on all other objects?

Good question!

Yes, only if the physics is about the astromony! If you are trying to ask about speed of light in space, its OK!

Some questions might seem to be off-topic because of too low quality or too low searching for answer by the asker.

If you are trying to ask, define astronomy. It can be on-topic but the answer was an easy Google, so the community would downvote them! Or even flag them. So first search thoroughly then ask here!
