Why we might never find all the answers
Since I was little I always loved sci-fi movies. Expolring the universe and interstellar journeys fascinates me even right now. Recently, I've been particularly interested in the first human journey to Mars. right now NASA with cooperation with other international companies are testing new rockets and technology that would be able to take men kind to Mars in the near future. I watched plenty of documentaries and conferences about the obstacles that right now unables NASA to complete this mission. 2 particularly interesting videos about sending humans to Mars which made me think about this issue As I was watching I thought a lot about the obstacles that scientists need to overcome in order to send humans to Mars. Of course the cause of these obstacles is our current knowledge which unables scientists to produce more technologically developed devices. But what is really an obstacle? Is it our knowledge or is it the important materials which do not exist?...
