"A very basic yet easy-to-overlook quality of the Universe is that everything is in motion, all the time. Even things that have united humanity across the ages and that we take for granted – such as the constellations and our relatively pristine view of the Milky Way – will evolve and disintegrate over the course of deep timescales."

🚀⚡ Pioneering Power in Deep Space:

From Voyager’s grand tour to Curiosity’s Martian trek, Radioisotope Thermoelectric Generators (RTGs) have quietly kept humanity’s farthest explorers alive by turning heat into electricity in the coldest and darkest reaches of space.

"It's good for the soul, I think, to be reminded that we live on a planet that’s in a solar system that's in motion, that's part of a galaxy. I think for me by looking up, by paying attention to the moon and the planets, I get this real sense of the cycles of life."

I like to think of my work as a philosopher of science and space in two ways. On the one hand, I am (whether by choice or by necessity) very analytical. For my doctoral research on imagination in space science, for example, I analyze theories, ethnographic data and arguments, and investigate how these fit with – or contradict – my own hypotheses. On the other hand, I am at heart a romantic and I search for the broader context of the stories in which science, technology and society come together. In that latter context I allow myself the freedom to draw analogies, to think in metaphors and to invent grand stories. I cannot say that there is a sharp dividing line between that analytical mind and my narrative disposition, but rather a shift in perspective, a different way of writing.

I hope I’ve managed to strike the right balance in my latest essay on Substack, Mapping Stars in Finland, where I bring my own experiences to the forefront while also weaving in historical insights. A Dutch version is available as well on my Dutch Substack, and you can find both links in my profile.

A quantum field isn’t “stuff” but an invisible ocean 🌊. Particles (like quarks) are ripples in it. When you try to pull quarks apart, the “rubber band” of the strong force doesn’t snap—it creates new quarks instead. Energy turns into matter. That’s why we never see lone quarks, only jets of particles.
