As an alternative view to the standard big bang cosmology, the quasi‐steady‐state cosmology argues that the Universe was not created in a single great explosion: it did not have a beginning, nor will it ever come to an end. The creation of new matter in the Universe is a regular feature occurring through finite explosive events. Each creation event is called a mini‐bang, or a mini‐creation event. Gravitational waves are expected to be generated as a result of any anisotropy present in this process of creation. A mini‐creation event that ejects matter in two oppositely directed jets is thus a source of gravitational waves, which can in principle be detected by laser interferometric detectors. In the present work we consider the gravitational waveforms propagated by linear jets and then estimate the response of laser interferometric detectors such as LIGO and LISA.
