Why Time Can’t Go Backward: Physicists Explain

Credit: Perimeter Institute (PI) for Theoretical Physics
Time is what keeps everything from happening at once,wrote Ray Cummings in his 1922 science fiction novel “The Girl in the Golden Atom,” which sums up time’s function quite nicely. But how does time stop everything from happening at once? What mechanism drives time forward, but not backward?

In a recent study published in the journal Physical Review Letters, a group of theoretical physicists re-investigate the “Arrow of Time” — a concept that describes the relentless forward march of time — and highlight a different way of looking at how time manifests itself over universal scales.

ANALYSIS: Wormhole Time Travel ‘Possible’ (If You’re a Photon)

Traditionally, time is described by the “past hypothesis” that assumes that any given system begins in a low entropy state and then, driven by thermodynamics, its entropy increases. In a nutshell: The past is low entropy and the future is high entropy, a concept known as thermodynamic time asymmetry.

  1. Das ficht einen Religioten nicht an
    Auf dem Konzil von Nicäa (Iznik) wird 325 n.C. der heilige Geist als Irrtum verdammt. Bischof Athanasius erklärt ihn 390 n.C als verbindlich für die Vulgata (Bibel). Der Heilige Geist reist dann 600 Jahre in der Zeit zurück und diktiert die ewig wahren Worte Zombies mit 35 Mio. Morden in 1035 Absurditäten, 377 Widersprüchen, 1094 Ungerechtigkeiten, 854 Gräueltaten und 539 Fällen krasser Inkompetenz.
