Overview
- Goyal posted an apology on X, saying he miscommunicated the Gravity Ageing Hypothesis by turning a complex idea into a dramatic reveal that made it sound absolute and commercial.
- His hypothesis links lifelong upright posture to reduced cerebral blood flow—citing up to a 17% drop in upright positions and an age-related decline—proposing brief daily inversions to boost 'brain flow.'
- Medianama reports he is considering a wearable venture called Temple to monitor brain blood flow, while the website currently states 'Coming Soon' and Goyal says he has used an experimental device for over a year.
- He argues brain blood flow is an accepted biomarker for ageing and cognition, adding the device could be useful even if the gravity-driven mechanism proves incorrect.
- Doctors and researchers, including Dr Cyriac Abby Philips, criticized the claims as lacking robust evidence and contradicting established physiology, urging peer-reviewed validation before consumerization.
