A science teacher I had in college named Mr. Bradley. He did many a scientific experiment to get my imagination. Not only that, he would explain things in great detail about how and why they exist and their puropse for what they do.

Von Daniken had some interesting theories.  While I do not believe specifically what he wrote, I do believe that we have been visited by extra-terrestials over the centuries.

there are many theories had been formulated by scientists...\n1. the big bang theory -- it states that at first there was a blazing or hot sphere...untill time goes on this sphere continues to acccumulate heat..after such time it bursted and emitted particles and this particles formed into different galaxies.\n2. the collision theory--scientist said that there was a comet heading to another comet in space..then this two comets collided with each other and there particles scattered into space and therefore creating galaxies.\nand there are other more theories..\nbut for me it is really god who created the galaxies and space...cause if there is a thing or a galaxy probably somebody puts it there..or somebody is responsible for it to be created...

SIR elbert einsten because he is the great scietist of history. his theory of relativity is very exellent . when this world lost after some lack year then then this theory help us because in the future scientist go on new world in the space.these all thing posible when einstien theory says\nthat  for example a man  (age=18)who live on earth and one who(age=18) which goes in the universe with the speed of light after 50 years the age of man which who live on earth his age 65 year. and one which goes in the universe with speed of light his age is 35 years. tell me which scientist is genius.
