Topics of Present Day Interest in General Relativity

[obo]

Hi there

I'm currently in a senior year intro GR course (at the level of Carroll and Ryder), and we're to write a research paper about a topic of "present day interest in General Relativity", about 15 pages in length.

I'm having trouble figuring out a topic that would be appropriate under the "present day interest" stipulation, and one that would in addition be easy enough to research and understand given this is my first course in GR. I mean I know that the main frontier right now is Quantum Gravity, but that seems a bit exotic and difficult for my level. What else is going on in GR right now?? I was wondering if anyone might have any good suggestions?

Thanks a lot for any ideas you guys might have!

Sorry I'm in a bit of a rush but look at gravity in higher (>3+1) dimensions is popular I hear: it is much richer. This is motivated by string theory which suggests our spacetime is more than 4 dimensional.
