Cosmological Cannibalism and Baby Universes
Science Time · 2024
"The rapid expansion of the universe — traditionally explained by cosmic inflation and dark energy — can alternatively be modeled as our universe systematically colliding with and absorbing smaller "baby universes" within a larger multiverse framework."
The prevailing model says a fraction of a second after the Big Bang the universe underwent exponential "Inflation," and continues expanding today via dark energy. But inflation requires hypothetical scalar fields never detected in any collider. A newer theory proposes the expansion isn't driven by internal energy at all, but external consumption: our universe growing by colliding with and swallowing smaller, nascent "baby universes."
In this model, the multiverse is a frothing topological space full of bubble universes of varying sizes. When ours collides with a smaller one, the boundary ruptures and the smaller universe's volume gets assimilated, producing a sudden, measurable leap in our spatial volume. The math of these continuous absorptions matches both the early inflationary period and the current accelerated expansion usually attributed to dark energy. Evidence may be hiding in the Cosmic Microwave Background as faint topological scars or temperature anomalies.
How does the baby universe absorption model explain current cosmic expansion without relying on dark energy?

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."
