William Shatner experienced profound grief in space. It was the 'overview effect'.

Last year, I had a life-changing experience at 90 years old. I went to space, after decades of playing an iconic science-fiction character who was exploring the universe. I thought I would experience a deep connection with the immensity around us, a deep call for endless exploration. I was absolutely wrong.

The strongest feeling, that dominated everything else by far, was the deepest grief that I had ever experienced. I understood, in the clearest possible way, that we were living on a tiny oasis of life, surrounded by an immensity of death. I didn't see infinite possibilities of worlds to explore, of adventures to have, or living creatures to connect with.

I saw the deepest darkness I could have ever imagined, contrasting so starkly with the welcoming warmth of our nurturing home planet.

This was an immensely powerful awakening for me. It filled me with sadness. I realized that we had spent decades, if not centuries, being obsessed with looking away, with looking outside. I did my share in popularizing the idea that space was the final frontier. But I had to get to space to understand that Earth is and will stay our only home. And that we have been ravaging it, relentlessly, making it uninhabitable.“ -- William Shatner, actor
