Carl Sagan was an astronomer, astrophysicist, cosmologist, skeptic and critical thinker. He was the Professor of Astronomy and Space Sciences and Director of the Laboratory for Planetary Studies at Cornell University. He played a leading role in the American space program and was a consultant and adviser to NASA since the late 1950′s. He was also responsible for briefing the Apollo astronauts before their flights to the Moon. Many of you might know him from some of his bestselling books, like Cosmos, which was in fact the bestselling science book ever published in the English language.
Sagan was responsible for assisting humanity in their knowledge of concepts that are outside of the box, these include multiple dimensions, quantum physics, wormholes, and a wide variety of ideas and concepts about space, science, technology and more. He did so with a great amount of enthusiasm, cheer, and an uplifting type of energy. In his very last interview he left us with words that might give you goosebumps,he issued two warnings to the human race.
His first concern was with regards to science and technology. Sagan expressed great concern that“if the general public doesn’t understand science and technology, then who is making all of the decisions about science and technology that are going to determine what kind of future our children live in, some members of congress? There are only a handful who have any background in science at all, and some of them don’t even want to know about it.” – Carl Sagan
