Overview
- Goyal posted a minimalist image on Instagram with the tagline “The most important wearable ever made” and told users to follow @temple to learn when the waitlist opens.
- Temple is described as a small device worn near the forehead that reportedly monitors cerebral blood flow and oxygenation during everyday activity using a non-invasive approach.
- The concept ties to Goyal’s publicly shared “Gravity Ageing Hypothesis,” which links lifelong gravitational effects to reduced brain blood supply.
- Goyal says he has been wearing and testing the device on himself for about a year, after earlier hints that it could eventually reach the public.
- Reports note the device is not for sale and lacks regulatory approval, as physicians and neuroscientists warn temple-based readings cannot substitute for MRI or PET, even as the teaser drew visible excitement online.
