Tout est dans le titre - Poussée par un vide, notre galaxie surfe à plus de 2 millions de km/h

L'univers issu d'un hologramme (phys.org) ?  Notre voie lactée poussé par du vide ...

The Dipole Repeller video. The video commences with the pre-sentation of the large scale structure by means of the surfaces that define the filaments and knots of the V-web. The motion of the Local Group with respect to the CMB is displayed by a yellow arrow. The growth of streamlines through integration steps from a regular array of seeds are illustrated. The fully developed streamlines clearly show a pattern dominated by a single repeller and a single attractor. The growth of the streamlines of the anti-flow is shown in a similar manner — the anti-flow is being repelled by the Attractor and attracted by the Repeller. A different presentation of the flow and anti-flow streamlines is obtained by confining the seeds of the flowlines to the neighbourhood of the Repeller (in blue-black) and those of the anti-flow to the vicinity of the Attractor (in orange-red). The attractive flow develops mainly in a plane containing the major over-densities: Perseus-Pisces, Lepus and Hercules. The repulsive anti-flow develops in the orthogonal plane that corresponds roughly to the supergalactic equator. The video reveals the almost exact alignment of the Local Group velocity vector with the Dipole Repeller and the much poorer alignment with the Shapley Attractor. The Repeller and Attractor constitute local maxima and minima of the gravitational potential. CREDIT: Yehuda Hoffman
