According to science, the answer is “yes”. If a tree falls in the forest, it would invariably emit sound waves even if no one is around to hear them. So, yay! You are a living breathing human being with a body and a desperate need of attention. But, according to the blogosphere, the answer is a resounding “no”. You do not exist. Not where it matters most — on the interwebs. What a conundrum — to simultaneously exist and not exist. Like Schrödinger’s cat. You’re both alive and dead at the same time.
