Can a late-time cosmological model based on baby universe absorption explain the z-variation of w?
Jan Ambjorn, Yoshiyuki Watabiki
We point out that a simple late-time cosmological model where our Universe can absorb "baby universes" explains the exponential expansion of our universe without the need of a cosm…
The emergence of the universe
Jan Ambjorn, Yoshiyuki Watabiki
We show how our Universe can emerge from a symmetry breaking of a multicomponent algebra, where the components in addition form a Jordan algebra. We discuss how symmetry brea…
Dynamical Triangulations for 2D Pure Gravity and Topological Recursion
Hiroyuki Fuji, Masahide Manabe, Yoshiyuki Watabiki
We show that, in two-dimensional Euclidean quantum gravity without matter fields, the Schwinger-Dyson equations derived within the Hamiltonian framework of non-critical string fiel…
Late time acceleration of our Universe caused by the absorption of baby universes
Jan Ambjorn, Yoshiyuki Watabiki
If our Universe is allowed to absorb baby universes, one obtains a modified Friedmann equation that can explain the late time acceleration of our Universe and there is no need for…
The causality road from dynamical triangulations to quantum gravity that describes our Universe
Yoshiyuki Watabiki
It is shown how one, guided by causality, starting from so-called dynamical triangulations, is led to a candidate of quantum gravity that describes our Universe. This theory is bas…
The large scale structure of the Universe from a modified Friedmann equation
Jan Ambjorn, Yoshiyuki Watabiki
We have already shown how a modified Friedmann equation, originating from a model of the Universe built from a certain algebra, is able to explainthe difference between the H…
