Categorically no. Science takes so much time and is so collaborative these days, even the big discoveries aren’t really just one person being brilliant, they’re a bunch of people being brilliant and hardworking together.
The idea of the independent genius scientist having major breakthroughs while working on some esoteric problem (that also happens to hold the keys to the universe) late at night in an office that used to be a broom closet just isn’t true in most fields anymore (except maybe the late nights and broom closet parts).
There were like 3000 authors on the higgs boson papers from CERN, because that’s how many people it takes to do that kind of high energy physics, and there aren’t really any major single author papers anymore. We work in teams now, teams that include undergrads and grad students and postdocs and professors of a large variety of ages, and that makes us better at our jobs.
Anyone who tells you that you can’t make significant discoveries outside of your early twenties is stuck in a past that never really existed for most scientists anyways. Of course there have been people who made major discoveries when they were young, and there still are, but I highly doubt that has ever been the majority of people making major contributions to their field.
Many, if not most, major discoveries are the culmination of years worth of work on a problem, and not a single stroke of genius, because that’s just not how science works for the most part. Destroy the idea that doing good science is based on inherent genius and not working your ass off to better understand the world.
