Spacetime as an Emergent Property
Science Time · 2024
"Spacetime and gravity may not be fundamental components of the universe, but macroscopic illusions emerging from the quantum entanglement of underlying, non-spatial data points — akin to temperature emerging from molecular motion."
Since General Relativity, physicists have treated spacetime as the fundamental canvas of reality — a flexible fabric warped by mass to create gravity. But General Relativity breaks down at the quantum level, producing infinities inside black holes and at the Big Bang. A radical alternative: spacetime isn't fundamental at all. Just as "temperature" doesn't exist for a single atom — it's an emergent property of billions of atoms moving — spacetime might be an emergent property of deeper, undiscovered quantum phenomena.

Scale-Invariant Unparticles and Cosmic Expansion
"The accelerating expansion of the universe, traditionally attributed to the Cosmological Constant, may be driven by "unparticles" — a theoretical form of scale-invariant matter that behaves as a macroscopic fluid defying standard particle physics."
