can you capture a photon and release it at Will?
YES, DONE WITH LASERS IN A COLD TRAP

Would Will need to duck, or would blinking suffice?
DEPENDS UPON THE ENERGY OF THE PHOTON - IF IT IS A GAMMA, THEN DUCK!
Is a photon a particle, or does it conform to the wave theory?
YES
Since light cannot escape a black hole, can we assume light consists of
particles with mass?
NO. IT IS ENERGY AND E=MC^2
Can these particles move slower than the so-called 'speed of light'?
YUP.... REMEMBER SPEED IS PROPORTIONAL TO TIME AND TIME IS
PROPORTIONAL TO VELOCITY IT IS ALL RELATIVE
Does high tide affect the speed of a photon?
YUP BUT MY STOPWATCH HAS TROUBLE WITH SUCH SMALL TIME CHANGES
At what point does a gravity wave affect a photon or light wave?
AT ALL POINTS
These questions need answers, gentlemen, so lets get with it.
Let me know when you're done.
DONE

WHAT DO I WIN?

BTW, while this is done in the spirit of fun all answers are accurate
as best I can make them based on my understanding of physics
