How Do We Separate the Brilliant from the Ridiculous?
Ray Jayawardhana: It's valuable to push your imagination and try to come up with all sorts of ideas and discuss them, debate them, test them, because it allows us to push what’s possible and open up new avenues.
It’s not often very easy to sort of tell the brilliant from the totally ridiculous because sometimes they’re not that far apart as they might seem at first sight.
Sometimes ideas that seem quite farfetched turn out to become reality much faster than you expect. And yet we are also not running around in jet packs. So it is not very easy to predict the future and a particular way something is going to work out or be applied.
With that said, as a scientist and as a science writer, I would use the criterion whether a proposed idea or a suggestion goes counter to already well-established and understood physics. Then I would say that’s likely not to turn out to be valid. However, there are ideas that are permitted within known physics and yet are perhaps impractical or just too expensive to actually carry out.
So some of the ideas that have been proposed, some of the schemes that have been cooked up around the practical uses of neutrinos, they range from using neutrino beams to signal aliens, which might be prohibitively expensive in terms of the energy it takes.
But it’s still interesting to push your imagination and try to come up with all sorts of ideas and discuss them, debate them, test them, because it allows us to push what’s possible and open up new avenues.

Butter supply and life satisfaction are linked – but by causation or correlation?
- Haiti and other countries with low butter supply report low life satisfaction.
- The reverse is true for countries like Germany, which score high in both categories.
- As the graph below shows, a curious pattern emerges across the globe. But is it causation or correlation?
Advances in satellite imagery are shining a light.
- Today, there are 40.3 million slaves on the planet, more than the number of people living in Canada.
- Slavery can be hard to find, but it commonly occurs in several key industries like fishing and mining.
- Using satellite data, researchers and activists are using crowdsourcing and artificial intelligence to identify sites where slavery is taking place.
The catacombs of Paris. Secret graffiti beneath NYC. The hidden cities of Cappadocia. Writer and explorer Will Hunt is your philosophical tour guide to what lies beneath.
- "The surface of the earth is where we're rational . . . Part of us dreads the chaos, and part of us is always attracted to it."
- "There were these things hanging from the ceiling…long strands of bacteria called "snotsicles"… But at our feet was a natural stream that had been running through Brooklyn forever."
- "It's…about death. Undergoing a death. We're going into the other world and then retreating to the surface… changed in some way."
