Pulsate

Men will always tremble at the thought of the hidden and fathomless worlds of strange life which may pulsate in the gulfs beyond the stars.

The hands trying to untie the knots / the ribbons speckled on the forehead / of poisonous spit, horrendous cries / he goes vibrating, making the air pulsate.

Delta Scuti stars pulsate in interesting ways.

The party pulsated with revellers.
