The Theory of the Photonic Symphony
What if life is not born, but switches on?
How did life arise from inert matter? Why does every living thing descend from a single ancestor? And if the universe should be teeming with life, where is everybody?
Three enigmas that science has not been able to close, read through a single hypothesis: light carries not only energy, but information. And matter, under the right conditions, learns to listen to it.
Three enigmas, one pattern
How did life begin?
No one has ever created life in a laboratory starting from non-living matter. Science describes the mechanisms, but the decisive step remains open.
Why are we all related?
Every form of life on Earth descends from a single ancestor, LUCA, and shares the same genetic code. Why one origin, and then never again?
Where is everybody?
Hundreds of billions of stars, planets everywhere, billions of years of time. And yet radio telescopes hear only silence. This is the Fermi paradox.
“This book does not ask you to believe. It asks you to look.”
