Brian Cox cites House of Lords figure: 18% of UK GDP relies on space
"So there was a house of lords report here in the UK last year and uh it was about space the economy of space and there's a figure in there which says that 18% of our GDP is relying on space-based infrastructure 18. So it's like a fifth of the economy of the UK."
About this episode
Davina McCall interviews physicist and broadcaster Brian Cox about cosmology, the origins of matter and the value of scientific thinking. Cox describes how the early universe’s hydrogen and helium, shaped by gravity and stellar evolution, produced heavier elements and ultimately planets and life, arguing that this narrative can supply perspective on human fragility and responsibility. He discusses the search for life beyond Earth, saying there is no confirmed evidence of other civilisations and suggesting it is plausible that technologically capable societies are rare.
Cox recounts his own path from touring as a musician to returning to physics, and explains his work at CERN’s Large Hadron Collider, where collisions are used to probe conditions shortly after the Big Bang. He also touches on how astronomical measurements are made, including the historical role of astronomer Henrietta Leavitt in establishing “standard candles” for cosmic distances.
On technology and policy relevance, Cox cites a House of Lords figure that 18% of UK GDP relies on space-based infrastructure, linking satellites to navigation, timing for financial systems and environmental monitoring. He also warns that quantum computing may eventually make today’s common encryption breakable, potentially rendering previously stored encrypted data readable, while noting potential benefits in materials science and biology.
The conversation returns repeatedly to uncertainty as a virtue in science and public life, with Cox arguing that progress depends on admitting what is not yet known.
Key takeaways
- Cox says a House of Lords report estimated 18% of UK GDP relies on space-based infrastructure.
- He argues that quantum computing could eventually break widely used encryption, potentially exposing data stored today.
- Cox explains how heavy elements form through stellar evolution and are recycled into planets and life.
- He describes CERN’s Large Hadron Collider as recreating conditions shortly after the Big Bang via high-energy particle collisions.
- Cox says there is still no confirmed evidence of extraterrestrial civilisations and suggests such societies may be rare.
- He highlights the scientific value of uncertainty, contrasting it with what he calls the rise of misplaced certainty and superstition.
