A new hypothesis transforms the explosive birth of the Universe into a smooth melting of quantum matter.

📄 Showing the "Simple" version — "Advanced" is not ready yet. Add it to favorites to help prioritize it.

The equations of Einstein and the model of Lemaître led to the conclusion that the Universe began from an infinitely dense point — the singularity of the Big Bang. At that point, familiar physics broke down, leaving the mystery of the first moment.

The new hypothesis bypasses the dead end: instead of a sharp explosion, a smooth melting. Curved spacetime momentarily loses its rigid structure, becoming malleable, like softening ice. This smooths out the expansion and replaces the singularity point with a uniform quantum material without ruptures.

This approach allows for astonishing scenarios. At the moment of smooth birth, mirror twin universes could have emerged: in them, time flows backward, and ordinary matter is replaced by antimatter. Perhaps our cosmos is only half of a symmetric whole, and the Big Bang was a quiet separation of the primordial state. These ideas push the standard model to incorporate quantum phenomena into the description of the universe's origins.

The beginning of the Universe can be compared not to a deafening fireworks display, but to the quiet melting of an ice block: spacetime doesn’t explode, but softly transitions into a new state, like ice into water.
