According to quantum mechanics theory (and answers appearing in MadSci) there
is a quantum vacuum or quantum foam in which very large numbers of particles
and antiparticles come into existence and go out of existence every second.
Near a black hole many of these particles remain in existence for reasons
explained on MadSci.

If an observer is in a reference frame moving at .9 c relative to an observer
in a second reference frame, must at least one observer and reference frame be
traveling at high velocity through the quantum vacuum? Or, is there a
different quantum vacuum for the two reference frames and for all the other
reference frames in the universe, so that the reference frame of every
observer is at rest relative to its own quantum vacuum?

(我本人过去也思考过这个问题，最后我认为真空宏观速度相对于任何惯性参照系恒为零）

Hi Fred,
thank you for that interesting question. I have seen an article on the net (http://www.ma.ic.ac.uk/~jeanluc/talks/rindler.pdf), "What a Rindler Observer Sees in a Minkowski Vacuum", where the authors argue that an observer accelerating relative to another observer has a different vacuum state. They define the vacuum for an observer being the state in which he sees no particles. The other observer accelerating relative to the first one will actually see particles in that state. The vacuum state depends on the observer. Observers moving at constant speed relative to each other will see the same vacuum state.
Greetings
Michael
