Why Zomato CEO Deepinder Goyal wears a mystery device just besides his eye?

Deepinder Goyal, the founding CEO of Eternal, the parent company of Zomato, Blinkit, District and Hyperpure, is sparking new controversy by proposing an unusual theory. Gravity itself may be aging our brains. Known primarily for his role at Zomato, Goyal has quietly poured his curiosity and money into longevity research through his venture called Continue Research, and is now developing a device to test his ideas.

Goyal has finally satisfied his curiosity about a small device he was recently photographed wearing on his right temple. The image had triggered widespread speculation, especially after Goyal shared the Gravitational Aging Hypothesis, which proposes that gravity reduces blood flow to the brain and contributes to aging. Many assumed the device was just a fashion statement or a speculative device, but Goyal confirmed that it is a research tool designed to measure blood flow in the brain in real time.

Temple device and Continue Research

Goyal’s Gravitational Aging Hypothesis has argued for decades that upright posture suppresses blood flow to critical areas of the brain and that long-term low perfusion can contribute to aging. He writes: “I share this not as the CEO of Eternal, but as a person curious enough to follow a strange subject… Newton gave us a word for it. Einstein said it warps space-time. I say gravity shortens life.”

To test this, he and his team built a small device that was placed on his temple and monitored his Brain Flow in real time.

What Does It Really Do and Where Could It Go?

So what actually is this Temple device? According to Goyal, this device is a sensor-based wearable device that continuously measures blood flow in the brain. It’s not a commercial product yet, but an experimental tool for the Continue Research team to validate their theories. If his hypothesis is confirmed, future iterations could become a meaningful wellness or medical device. In his view, through daily inversions, upside-down posture can become a practical intervention to balance what he calls gravity.
caused aging.

He argues that the device is valuable even if the hypothesis turns out to be wrong. “Brain Flow is already well established as a biomarker for aging, longevity, and cognition. So, even if the Gravitational Aging Hypothesis turns out to be false, this device is useful and relevant.”

Goyal, who also founded the Temple company in mid-2024, announced that he had been wearing the device for more than a year while conducting experiments to confirm his hypothesis.

Backlash against “pseudoscience”

While researchers and biohackers have expressed curiosity, some have also cautioned that the science of gravity-induced brain aging is still in the research phase. Many doctors and scientists have openly criticized Goyal’s theory of gravity as speculative and even irresponsible. One reviewer sternly warned: “Please DO NOT REVERSE for brain health and super aging… This is pure pseudoscience.”

Another point of contention. Goyal uses examples such as bats perching upside down to support his claims. He argues that their inverted posture helps preserve brain perfusion. “Bats are the longest-living mammals… They spend long periods inverted, with their heads below the heart. Gravity may be behind these exceptions.” But scientists counter that this is a simple comparison. Bats’ longevity is likely due to a complex mix of metabolic, genetic and evolutionary factors, not just gravity.

Replying to a LinkedIn user Shubham Mishra. Goyal emphasized: “Temple will be a cute little company. It doesn’t compare to Eternal. We didn’t make up the Gravitational Aging Hypothesis to sell Temple. It’s not my game to lose our customers’ trust in me because of a marketing gimmick.”

Business Link Startups Hypothesis and Big Bets

This isn’t just theory. Goyal is already laying the foundation of the business. Longevity initiative Continue Research has announced a $25 million personally supported fund to support global scientists investigating the fundamental mechanisms of aging.

Continue’s research roadmap includes studying cerebral blood flow, neurovascular aging, and how inversion can counteract the influence of gravity. According to Goyal, the aim is not to confine the findings to a private laboratory, but to make them open source and available to the broader scientific community.

Goyal is not just a man of ideas. As CEO of Eternal, he sits atop a diverse group that includes Zomato, Blinkit and more. Critics claim that he leveraged both his job and his passion for science to push the idea into the mainstream.
