Reframing spacetime – a stitch of events or pitch of time

In quantum field theory, if gravity isn’t a fundamental force, how does it emerge? This article describes a theory of deep quantum electromagnetic interactions. Photon transactions (emission / absorption) populate a relational network of events which structures spacetime. According to the theory, each transaction gives rise to a pair of events in spacetime, effectively stitching… Continue reading Reframing spacetime – a stitch of events or pitch of time

Whence the arrow of time?

[“Quantum foundations” series] A physicist walks into a bar, and asks the bartender, “What time is it?” The bartender is about to reply but then recognizes the customer. “You’re a physicist, correct? So, it’s a trick question.” So, what’s with time? A venerable philosophical question. A foundational question in physics. We have electronic devices, extremely… Continue reading Whence the arrow of time?

A photon’s frame of spacetime — no rest for the massless

I’ve thought about this question for years. A FAQ. Imagine you’re traveling at the speed of light. Well, physics says that’s impossible. Mass’ gotcha. So, what can travel at the speed of light? Photons (not just the visible ones). So, imagine … does a photon “experience” space and time? Some weeks ago I recall reading… Continue reading A photon’s frame of spacetime — no rest for the massless
