Editor's note

Do we experience a moment of euphoria as we die? Have humans evolved beyond nature – and do we even need it? Is love just a fleeting high fuelled by brain chemicals? These are just some of the questions we’ll answer in our new Life’s Big Questions series, co-published with BBC Future.

I still remember finding out that the universe may be infinite, potentially containing identical copies of myself. I found it impossible to imagine, yet I couldn’t stop thinking about it. I am not alone. Humans have always obsessed about existential questions concerning life, death and the universe. After all, age-old questions such as “Who am I?” “Are we alone in the universe” and “Is there life after death?” lie somewhere behind many of humankind’s greatest achievements, from the pyramids to Apollo 11.

But while we all ponder such questions from time to time, we rarely discuss them with those around us. Perhaps it’s because we fear they’ll trigger an eye roll at a dinner party, or an awkward silence at work. This may be because we believe they are just too naive, dark or even pointless, the kind of questions a child would ask – not realising that there are no definitive answers.

At The Conversation, there’s no such thing as a question that’s too naive, too scary – or too big. Working with BBC Future, our new Life’s Big Questions series is about getting you, the reader, more involved. From the nature of happiness and the origins of consciousness to the concepts of evil and free will, we believe that experts can provide fascinating perspectives, perspectives most of us may never have considered. You simply need to ask.

If you’d like to get a question answered, please formulate it in two to five sentences and submit it to bigquestions@theconversation.com. Articles will be published weekly on The Conversation and BBC Future. Today we are launching our first two stories, about death and nature. Also check out our story about why death inspires so many writers and artists.

Next week, we’ll find out whether love is just a fleeting high fuelled by brain chemicals. The answer certainly surprised me.
