The universe at it's base is a fluctuation of energy and matter. Life and humans especially are a definitive part of the universe because we along with other animals observe and react to these influxes in unique ways depending on each sense and each individual interpretation. As man evolves so does man's view of the universe, take time for example. Time has been around and flowing since...forever, but just until recently in the history of mankind, man has been able to grasp the idea of time. First we created the clock, which divided time into equal intervals, seconds to minutes to hours etc., and since then man has somewhat "tamed" the idea of time because now man can talk and think of time relative to another. Now think of this, did time exist before life, or simply did the idea of time exist before life? This may sound silly but if there was no living creature to observe time, then the idea and phenomenon of time may not exist, there would simply be an infinitely small fraction of time in which everything in the universe is expressed, there would be no time because there would be nothing to observe time. Now think of THIS, if only the idea of time existed before life could experience it, then think of the infinite amounts of theoretical "ideas" or "senses" or "types of experiences" that life (or at least man) has not experienced and cannot comprehend. This all comes together because as the title says, man and consciousness define the type of reality they experience, and as the way we physically experience things and mentally process things change, our literal idea of life and the universe change. just an idea that came to mind one day B) please comment your thoughts and if you agree or disagree and why!!!
