Friedrich Nietzsche theorized that we will live our lives over and over again: the myth of eternal recurrence

Rather than a theory of physics, the idea is designed as a moral argument. While Nietzsche famously eschewed the Christian afterlife, he wanted to avoid the nihilism that results from no longer having such an ultimate horizon. In a mystical moment, the philosopher came to believe that the fleeting moments of our lives would be repeated, presenting a test: would you want to relive this moment? If not, he would argue, you're not living well.

A psychiatrist warns that chasing happiness can lead to misery

Rafa Euba, a retired consultant psychiatrist, argues that happiness is a vague and abstract concept that is hard to quantify. He suggests accepting that suffering and pain are a normal part of life.

Philosophers have debated the nature of time since at least the 6th century B.C.E.

Greek philosopher Parmenides of Elea was skeptical of time and reasoned that if it were real, then the present would emerge from nothing because the future did not yet exist. Just as the color red is our perception of a specific wavelength of light, others have suggested time is a psychological projection based on how we interpret the world.

Virtually experience a euthanasia roller coaster

In 2010, Lithuanian artist Julijonas Urbonas came up with a fictional euthanasia coaster to generate conversation about humanely ending life.

Albert Camus believed existence was 'absurd'

When your 9-to-5 becomes optional

You've seen the headlines. But what would actually happen if everyone's 9-to-5 became optional? We dug into the data. Traced automation philosophy back thousands of years.

Despite claims of limitless free energy, zero-point energy cannot be harnessed

Since descending to even lower states is forbidden, extracting meaningful amounts of energy from an empty vacuum is impossible.

Hacking the body for a future that didn't happen

Journalist Adi Robertson experimented with one of the most accessible biohacks: magnets. Having a tiny magnet in their right ring finger meant they could sense magnetic fields, attract small metal objects, and more. But magnets weaken over time, eroding this new sense. Such implants do more than offer a new way of interacting with the world, they also pose new complications, such as the inability to get an MRI.

Nostalgia is a psychological coping mechanism that can help combat loneliness—but it's created from bias
