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.
Emergent Gravity ties closely to the Holographic Principle and quantum entanglement. Physicist Erik Verlinde proposed gravity as an entropic force — a statistical consequence of the universe maximizing entropy, not a fundamental interaction like electromagnetism. Newer models theorize that space itself is stitched together by entanglement: the "distance" between two particles is a macroscopic measure of how entangled the underlying quantum data is. Remove the entanglement, and space itself dissolves.
How does the concept of temperature relate to the theory of Emergent Spacetime?

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."
