Zomato CEO Deepinder Goyal has offered the first official glimpse of ‘Temple’, an experimental device designed to monitor brain blood flow in real time. After weeks of speculation around a small gadget seen on his right temple, Goyal confirmed that the device is part of his ongoing research linked to the Gravity Ageing Hypothesis (GAH), a theory he is exploring which suggests that gravity may directly influence the human ageing process by reducing blood flow to the brain.

Calling Temple a “world-class” innovation, Goyal shared that it aims to measure brain flow accurately, continuously, and non-invasively. He invited users to follow the official Temple account for updates, signalling that more announcements may be on the way.

Goyal described his hypothesis as “scientific yet unconventional,” adding that while Newton defined gravity and Einstein explained its impact on spacetime, he believes gravity may also play a role in shortening human lifespan. The device marks the first hardware outcome of his deep personal interest in longevity and anti-ageing research.

Addressing earlier criticism, Goyal acknowledged that he had initially miscommunicated the GAH concept, noting that compressing years of research into a social media post made it appear overly dramatic and commercial.
