Is the universe infinite, or do you come to a big wall with a sign that reads “End of the Road?” What is the nature of time, and can you get overtime? Is there life after death, and whatever happened to this one? What is truth, and how do I get some?
These are the questions I love to ask, which explains why I don’t get invited to a lot of cocktail parties. I mean, you can’t go up to someone you’ve just met and blurt out, “Why do we exist?” Social etiquette requires that you at least lead up to such questions with “So how do you like this weather?” or “What have you done with your face?” (OK, this last one may not be appropriate, but aren’t you dying to know?)
Being a geek, I especially enjoy the big science questions. What is consciousness, for example, and how do I know that I have it? Yes, I have this brain and all those neurons and stuff, but how does that translate into an awareness that someone is staring at my breasts or unzipped fly?
Or what makes us human? We know that other animals also use tools, language, and recognize themselves in mirrors. We share 99% of the same genome as a chimpanzee. So what makes us so special? Personally, I think it’s our ability to use credit.
Is there more than one universe? Just when I think I’ve got a handle on how vast our universe is, some physicists propose that we might actually live in a multiverse. There could be all kinds of universes—here, there, everywhere—constantly popping into being through something called “eternal chaotic inflation,” which sounds like a perpetual string of gas attacks. There could be zillions of different universes. Maybe there’s one where I have an exact twin, only he’s rich and famous, with six-pack abs, and can recite all the words to the song “Louie Louie.” Or there’s one where you can always get what you want.
Ever since childhood, I’ve been fascinated by questions about existence. I wake up and look in the mirror and see this face staring back at me, like some freak of nature. An assemblage of genes, bones, and tissues, I know that I am the unique result of a union between egg and sperm and millions of years of evolution. My thoughts identify with this thing in the mirror. Yet all of a sudden it seems odd to me that I should be here at all. What a twisted series of events it had to be that brought forth a ridiculous creature like me.
The animal books I read as a kid didn’t help. I’m not talking about Peter Rabbit or Winnie-the-Pooh. I’m talking about actual animals. Certain pictures terrified me. I remember a photo of a stuffed fruit bat that scared me silly. It seemed to leer back at me from the page. The more books I read, the worse it got. Pangolins, platypuses, star-nosed moles, giraffes, okapis, giant isopods, aye ayes, blob fish, naked mole rats, narwhals, and rhinoceri—they all seemed too bizarre to be real. How could such creatures possibly exist in the same world I inhabit? Nature must be insane.
Indeed, why should I or anything exist at all? To not exist sounds much easier. It certainly takes less energy. Some days, merely existing is all I can manage.
Some say there’s a reason for existence. We’re here to praise God, Allah, or Whatever. We’re here because a divine force willed the universe into being. We’re here because of the Big Bang. We’re here out of pure luck that matter and anti-matter didn’t cancel each other out at the beginning of time. We’re here because the economy needs more consumers.
Of course, it could be all an illusion. How do you really know you exist? Maybe we’re all just part of a story endlessly played out in some computer game. Though it may seem real to you, you may be nothing more than a made up character. René Descartes famously declared, “I think, therefore I am.” But just because you think you exist doesn’t necessarily make it so.
And what’s so great about existing? True, there are many advantages. Existence can be rather nice, if you can afford it. But you also have to go out and kill something to eat, get a job, reproduce, fight traffic jams, and pay taxes, unless you’re a rhino, in which case someone will take your horns instead.
The worst part is, it all comes to an end. It doesn’t matter whether you’re a mushroom, redwood tree, sea slug, gorilla, or frazzled commuter, the result is always the same. One day you’re here, the next day you’re not. There is no escape clause and no returns allowed. Even stars and galaxies die in the course of their vast cosmic lifetimes.
At least your atoms will still be around. Who knows where they might end up someday— perhaps in a whale or an eagle, or some wholly new life form. Wouldn’t that be something? No matter how useless your life may seem at times, it’s nice to know your atoms will serve a constructive purpose in the future.
Our universe itself may die one day. I imagine it would be pretty exciting to watch, though hard to get a good seat.
For now, though, I must bid you all goodnight and go to bed. Existence is exhausting.
