If there's a synaptic gap between neurons, then why don't they just float away from each other? Are they attracted to one another like magnets in a way?

There are extracellular adhesion molecules, expressed specifically at synapses, that promote and stabilize synapses. Some examples include ephrins, neuroligins, and neural cell adhesion molecules. Also, perineuronal nets also seem to promote synapse stability.

Astrocyte processes may also help structurally stabilize (CNS) synapses.
