If you are referring to inflation of the universe caused by the Big Bang, and the subsequent "ripples", then those ripples are the leftover, background radiation from the event.

Synaptic cleft
Explanation:
Synapse is the region where the impulse is conducted between two neurons. This occurs because two neurons are in maximum possible proximity to each other at the synapse.
However, there is no physical contact between two neurons even at the synapse. And a small space is present between two neurons at synapse. This gap is called the synaptic cleft. The neurotransmitters are released in this cleft.

Scientists use scientific method and do all sorts of experiments to prove their theory
