Und von der "dunklen Energie" in der Kosmologie ist ganz zu schweigen....
Ich bin sicher, "erneuerbare Energie" ist "dunkle Energie".....
Das Kabinett Merkel arbeitet intensiv daran, den empirischen Nachweis dafür zu erbringen.
Schon bald gehen hier die Lichter aus......
Bemerkung: in der Gravitationstheorie von Einstein gibt es keine Energieerhaltung...
[Links nur für registrierte Nutzer]The point is pretty simple: back when you thought energy was conserved,
there was a reason why you thought that, namely time-translation invariance.
A fancy way of saying “the background on which particles and forces evolve,
as well as the dynamical rules governing their motions, are fixed, not changing with time.”
But in general relativity that’s simply no longer true.
Einstein tells us that space and time are dynamical, and in particular that they can evolve with time.
When the space through which particles move is changing, the total energy of those particles is not conserved.
