Eternal youth-seekers and investors alike are getting increasingly excited about a concept called “Longevity Escape Velocity.” This hypothetical idea borrows its name from “escape velocity,” the basic physics principle which states that objects can, at a certain speed, defy gravity’s pull.
Longevity escape velocity suggests, similarly, that at some point in the not-too-distant future people will be able to escape the debilitating pull of death — and live indefinitely. Longevity escape velocity is our ticket to immortality. If only science could figure out how to cash it in.
