"The idea that space-time exists is no more viable than the outdated belief that the celestial sphere exists: both are observer-centred models that are powerful and convenient for describing the world, but neither represents reality itself." www.realclearscience.com/articles/202...

Space-time is a powerful and useful map — but it isn’t reality itself. Building from first principles, I argue that space-time, as the sum of all events, literally cannot exist. Recognising this distinction clears up a century of conceptual confusion in physics. 🔭🧪 #cosmology

My article on the nature of space-time just crossed 100,000 reads. This isn’t just a milestone — it’s proof that big, difficult questions about the nature of reality still resonate. Here’s why that matters, and why I think this is just the beginning. cosmicave.org/2025/09/22/o... 🔭🧪#cosmology

What kind of thing is it — is space-time structure, substance or metaphor? Read here: buff.ly/fg3RmlO 📸 Rick Rothenberg/ Unsplash). CC BY 4.0.
