Particle accelerators are used to boost particles to very high speeds. The particles must be charged because electric and magnetic fields are used to accelerate them.
Particles are then collided and smashed apart so that their make up can be examined.
Black holes are 'cosmic crushers' with very strong gravitational fields, so strong that not even light can escape from them. They were 'invented' in the first place by theoreticians, but astronomers reckon they have discovered one or two possible candidates for 'black hole' status. They still remain astronomical anomalies which are not really understood so cannot really be created.
