SRM University-AP hosted Phy-Spark 3.0: Stars, Scopes & Spacetime on September 13, 2025, as an outreach initiative for school students. A combination of lectures, experiments, demonstrations, and interactive sessions took place throughout the day-long programme introducing young students to the exciting fields of physics and astrophysics. 120 students from Geethanjali School, Kunchana, K V School, Nallapadu and Vijetha School, Guntur participated in the programme.

A public lecture delivered by Dr Shivaraj Kandhasamy, renowned scientist from the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, on the Detection of Gravitational Waves by LIGO was the highlight of the programme. Dr Kandhasamy explained how gravity shapes the fabric of spacetime and introduced the concept of gravitational waves. He walked through the historic Michelson-Morley experiment, the design and functioning of the Laser Interferometer Gravitational-Wave Observatory (LIGO), and the challenges of detecting such incredibly faint signals. The lecture also covered landmark detections, including gravitational waves generated from black hole mergers and binary neutron star collisions.

Expert faculty members Dr Gangireddy Salla, Dr Ashmita Das, and Dr Krishna Prasad Maity from the Department of Physics of SRM AP delivered academic sessions on several intriguing topics such as Telescope: Fundamentals and Designs, Binary Star Systems and General Theory of Relativity. The lectures were followed by a lab visit and live demonstrations of telescopes, binary star experiment using LED bulbs, Michelson interferometer etc., and an interactive Q&A session facilitating hands-on experiential learning on astronomical observations, scientific equipment, and the application of ideas they had learned in theory.

The programme conducted to ignite the spirit of learning physics among the budding minds of school students was a resounding success. Through Phy-Spark 3.0, SRM University-AP successfully made complex concepts in physics and astrophysics accessible to school students providing them with a glimpse of how physics is applied in real-world research environments. The event was coordinated by Dr Pranab Mandal, Dr Gangireddy Salla and Dr Soumyajyoti Biswas of SRM AP.
