I’m no Genius although I’m watching the show and am a bit lost but that doesn’t mean I don’t enjoy witnessing science right in front of me and today such an event came within my eyes. For I walked down a dark path that had only one light bulb shining and preceded to turn it off before staring at it when science hit my eyes! In this darkness even though the light was off I continued to see the light bulb as if it was still on and as I walked away until a new light came my way. As the great scientist I sought to be this morning I redid the test and the same event occurred. I’m pretty sure I’m not insane because there were no Pink Elephants carrying the light bulb although that would be fascinating! What is the called? Has this happened to you?
