| Abstract : | The detection of the gravitational waves by LIGO has ignited a profound and fervent enthusiasm within us. Although students try to understand the phenomenon from teachers who are not professional Astronomers or Astrophysicists, it is quite difficult to visualise the propagation of these waves in 3D space-time. In this regard our 3D model tries to explain the propagation of gravitational waves and hence encourage and spark curiosity among the undergraduate students in astronomy and astrophysics.
The model is experimentally able to depict the gravitational waves echoing their cosmic counterparts, propagating outwards from the system, exhibiting as sinusoidal nature consistent with quadrupole waves generated by a binary star system in space.
The two balls revolving around one another in the medium, analogous to the accelerated binary system, create a pattern which is clearly visible bearing a striking resemblance to gravitational waves in space time.
Although earlier many have tried to demonstrate this phenomenon earlier using similar techniques, in the present demonstration we have tried to give an interactive touch, and a hands-on learning experience. Students can themselves build this model, and we have several versions of the same working principle so as to enhance the understanding of this topic. Different versions of our model could be used to teach students in different grades, making it comprehensive for all age groups.
This is an ever-evolving model, with scope for modifications and adjustments based on one’s needs. Our model is inexpensive and easy to construct, hence being an easy teaching aid for teachers and students everywhere.
