Zomato-parent Eternal founder Deepinder Goyal has sparked debate after sharing Continue Research’s newly published “Gravity Aging Hypothesis,” a theory suggesting gravity may play a role in human ageing.
In a post on X, Goyal wrote: “Could gravity be the reason we age?”. “It was an idea I had never encountered before. In all my years exploring longevity research, I had never seen gravity discussed as a factor in aging. I knew instantly that I was onto something, at least something new to me at that moment,” he continued.
What Deepinder Goyal said in the post
According to Goyal, the hypothesis reconsiders how the brain manages blood flow and how posture, gravity and everyday movement may influence long-term neurological health.
He said skepticism often reflects older assumptions about brain function, while recent findings from spaceflight research, brain perfusion studies and autonomic disorders point to new directions.Continue Research has also released a separate document addressing questions raised after the announcement. It explains topics such as autoregulation, the “astronaut paradox,” evidence from bats, variations linked to height, and why yoga practices are relevant to the discussion.
The organisation said its early data shows passive inversions — simple positions like resting with legs elevated — increase cerebral blood flow by about 20.2%. Active inversions used in yoga show an increase of 13.3%. It added that 10 minutes of daily passive inversion across six weeks led to a 7% rise in average daily brain blood flow among study participants.In a follow-up post, Goyal wrote:“Thank you for your attention to what we published yesterday.
And an even bigger thanks to all the skeptics. Nothing strengthens science like good skepticism.” He said the idea is not a statement of fact but a testable hypothesis that requires scientific evaluation.Goyal said he is sharing the work as an individual interested in biology and not in his capacity as Eternal CEO. He wrote that the hypothesis is open-source, and that the team is running studies designed to support or refute it.
A separate internal group has been created to focus on attempts to invalidate the idea.Goyal said several scientists have expressed interest, but he noted that the hypothesis still needs rigorous evidence. Continue Research is now working with scientific teams to design further tests. He added that the aim is not to claim gravity causes aging but to examine whether it could be a contributing factor that has not been fully explored.
Goyal’s post sparks debate
“Wait. If gravity accelerates aging, then every anti-aging breakthrough so far has just been treating the symptoms, not the cause,” questioned one user. “Is this published anywhere or is it just some random hypothesis? Also, if I invert myself for 30 mins, blood flow is only increased for that 30 mins technically right?,” said another. “Gravity affects the rate of telomere shortening over time !?!,” wrote another.
