The chapter explores the space–time configuration of youth-voice driven science practices outside of school that are part of an emergent field of study known as informal science education (ISE). Education is an emergent phenomenon grounded in a relational geography of youths’ complex space–time configurations. A focus on youths’ mobilities offers new insights into the manner youth contribute to their own learning and becoming.

We present a regular spherically symmetric cosmological model of the Lemaitre class distinguished by the holographic principle as the thermodynamically stable end-point of quantum evaporation of the cosmological horizon. A source term in the Einstein equations connects smoothly two de Sitter vacua with different values of cosmological constant and corresponds to anisotropic vacuum dark fluid defined by symmetry of its stress-energy tensor which is invariant under the radial boosts. Global structure of space-time is the same as for the de Sitter space-time. Cosmological evolution goes from a big initial value of the cosmological constant towards its presently observed value.
