Om det fanns ett maskhål i rymden eller "vitt hål" som en genväg till annan del av universum, den ser ut som en tredimensionell sfär där man kan se rymden från andra sidan osv.
Nej, maskhål är
inte genvägar genom rummet. Snarare genom tiden, enligt denna artikel:
New study shows wormholes aren’t tunnels, and the Big Bang was a bounce
som refererar studien:
A new understanding of Einstein–Rosen bridges
Man har i en studie gått tillbaka till Einsteins och Rosens ursprungliga idéer från 1935, och säger bland annat att:
"Their “bridge” was a mathematical construction that linked two perfectly symmetrical copies of spacetime. It was designed to keep physical equations consistent, not to allow anything to pass through."
"a full quantum description must include two components: one where time moves forward, and another where it moves backward"
"The Einstein–Rosen bridge, in this view, is not a tunnel through space. It is a mathematical connection between these two opposite arrows of time."
Därmed följer en rad intressanta påståenden:
Om svarta hål: "information is not destroyed at the event horizon. Instead, it continues evolving along the mirror, time-reversed component of the quantum state"
"the same time-mirror structure could apply to the entire universe. The Big Bang may not have been the absolute beginning of time, but a quantum “bounce”—a transition between a contracting universe and an expanding one, each with opposite arrows of time."
"Some traces of the pre-bounce universe—such as small black holes—might have survived and reappeared in our own cosmic expansion" -- i form av mörk materia!
"our universe could be the interior of a black hole formed in a previous cosmos"
Känns detta som något nytt och förklarande för förståelsen av "a unitary description of quantum field theory in curved spacetime (QFTCS)"?
