Great! Congratulation for achieving a remarkable feat at a young age.

I do have one general question, not specific to him. I am just asking what other people think about such a situation. Is there a scientific method to verify the age? Because I have seen my friends reducing their age intentionally to take part in international competitions.

I know there are prodigies, and even if he is not 16 it doesn't matter to me because he beat the world champion. He deserves the accolade :)

Does he look older than 16 to you?

No! That's why it is a general question, not targeted at him. Also, my friends claimed to be 14 when they were 16 because the international competition was restricted to 15 years old. However, in this game age doesn't matter, so it is irrelevant whether he is older than 16 or not.

As a general answer: As far as I know, there is currently no exact scientific method to measure and determine the age of a person.

Certain techniques can give more or less rough estimates, however a precise technique that works for all age groups is tricky.

The following article is from 2014, but gives a good glance at several existing methods and directions of research.

It should be noted, that many techniques in this area are invasive, requiring blood/tissue sampling and/or exposing a person to ionizing radiation (XRays), which makes them prohibitive in many scenarios.
