here is one possible tactic
a very eminent world authority on new theories of cosmology is
Abhay Ashtekar. He grew up in the Bombay area, if I remember correctly.
He leads a research institute at Penn State and he has a website with links to popular articles as well as technical articles.
In my personal opinion, his work is considerably more interesting and important than anything Stephen Hawking has done since, say, 1980. Hawking gets celebrity and media attention, but Ashtekar and his research team actually make progress.
One strategy would be
1. visit Ashtekar website
2. read the easy parts of a recent Ashtekar article called
"The Issue of the Beginning in Quantum Gravity"
3. tell the committee that Ashtekar is a hero of yours and you are interested in his research into the origins of the big bang.
Ashtekar was not a complete intellectual when he was a teen ager. He liked sports and played a lot of soccer. You say you are 16 years old and your interests are "...singing, playing baseketball,cricket,etc. reading and writing and science,eating,sleeping,thinking." That sounds similar to Ashtekar as a young man. He didnt start out having his nose in a book all the time.
But by age 40 he was among a handful of top people in quantum cosmology.
Now he is in his 50s I estimate, or early 60s.
He seriously considers that quantum mechanics allows that the big bang could actually have been a "bounce", where a prior gravitational collapse achieved very high density and pressure and turned around into an expansion.
His group has been computer-modeling this and attempting to get predictions that can be tested by observation of the CMB (cosmic microwave background).
anyway that is one idea for you. I will get some links. so you can have a look if you want.

His CV (curriculum vitae, life history) says he got his Bachelors degree at U. Bombay in 1969, so he might have been born around 1948----my guess could be right, that he is late 50s.

He has made a collection of what he calls SEMI-POPULAR ARTICLES here
http://cgpg.gravity.psu.edu/people/Ashtekar/articles.html
these are links to articles that are freely available online and which explain things about quantum gravity and cosmology WITHOUT USING TOO MUCH MATHEMATICS. they are accessible to non-specialists.
Ashtekar's approach must still be verified by observationally testing predictions----all theories must be. I think it has a good chance of being right, but you have to decide that for yourself. At least it is consistent with the astronomical observations made so far (because so far it agrees with the classical model, General Relativity).
the article I mentioned "The Issue of the Beginning" is partly technical and partly non-technical. I don't know how much you can actually get out of it but i will give a link. I think it is a serious, thought-provoking, scholarly article but it might be just a little too hard to read for you. Go here
