Many scientists have shown us repeatedly that there are many things we do not see evidence of, but are indeed very real. For example, we now understand that matter is compressed energy. Albert Einstein theorized this in his famous equation E=MC2. We never saw evidence of this until our technology advanced to the point where atomic bombs were created, based on this equation. Even more recently, quantum physics has opened our eyes to even more phenomena, which we are only now understanding, and are not able to experience fully. Scientists have been only recently able to teleport an atom, have discovered there are at least ten dimensions and that you can transfigure any object or person to with the superstring theory( A theory which states that all particles vibrate at a certain frequency and when a particle vibrates to match that of another it becomes or transforms into that particle.) Although these new laws of physics were always present in our world, we did not experience their effects until we learnt about them, and possessed the technology to see it in action. We are constantly discovering more and more facts which are incredible and sound as though they are science fiction. Scientific history is full of periods of time where human kind has believed that we discovered everything there is to know about the universe, only to be proven wrong as knowledge and technology progressed; their theories were corrected which they had previously thought were accurate and exact. We used to believe the Earth was flat, remember?
And, you must ask yourself: "Is it possible that we do not know everything and have not experienced all there is to discover?
