It is well-known that there is no spherical/topologically spherical gravitational waves in vacuum space in general relativity.We show that a deviation from general relativity leads to exact vacuum spherical gravitational waves, no matter how tiny this deviation is.We also discuss the related topics, including LED Touch Lamp Vaidya-like metric in f(R) gravity.We demonstrate that the existence of spherical gravitational wave is a non perturbative property for gravities.

We investigate energy carried by this nonperturbative wave.We first find the wave Memory Foam Mattress solution from investigations of Vaidya-like metric in f(R) gravity, which has only one longitude polarization.We further extend it to a metric with two transverse polarizations by directly solving the field equation.
