In my portfolio thesis I has chosen two topics which according to me needs more exploration for the benefit of mankind. I had spoken about the advancement of medical science by which fatal diseases could be cured and I had also spoken about the opportunities of space exploration to find a sign of life in the outer space. My Professor suggested to me to narrow down to one topic and so I chose the second topic and thus I will be working upon “The search for new home and new neighbours- The existence of life in outer space”.
