If scientists cannot see black holes and do not know for certain that they exist why might studying them be important?
The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk. Also, scientists are PRETTY SURE that black holes are real. As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.
Do black holes use gravity?
Yes. Black holes suck things inside. The only way to suck these things inside is by massive form of gravity. Black holes can suck in as little as a small chunk of rock, or as big as a planet. Black holes don't "use" gravity, they are a side effect of it. To create a black hole requires a force that can grow infinitely: of the strong nuclear, weak nuclear, electromagnetic and gravity forces, only gravity is infinite in it's strength that is it is based on the masses and distances of the objects involved, it has no limit. A black hole is generated when enough mass joins together and the force of gravity generated is so strong that light can't escape it (at event horizon and lower.) In most cases for the mass to get that heavy, gravity has to bring them together in the first place (every so often high speed collisions will join masses, but it rare.) It's almost a snake biting it's tail: gravity pulls the parts together, the parts coming together increases gravity, that gravity pulls more parts .......

Gravity.

What role did gravity play in the formation of the planets?
Gravity, of course has a central role in formation of planets. It's believed that the planets origin can be traced to the debris swirling around a young star. The term used for coming together of particles or bodies and joining together is 'accretion'. Gravity is the reason behind accretion . Small debris join together due to accretion and this accretion occurs further to give rise to larger and larger bodies like planets . Without gravity, this could never have occurred.
How dynamic are black holes?
Not quite sure what you mean, but black holes are among the brightest objects in the Universe, and they seem to play an important role in the evolution of a galaxy.
