Any theory describes real world to some degree.

:-/ We can test my ideas in your laboratory, of course.
> You quite misunderstood that article, it's not the vacuum that produces the particles, it is the massive energy they are beaming that produces them.
Do you really read article? Of course, energy is necessary, because two vacuum particles will cannot escape each other and will annihilate. But you cannot produce particle using just energy.
> The stuff in the wikipedia article is just ideas that may work mathematically but have little bearing on the real world. At least for now. Maybe someday we'll figure them out, but for now it's just ideas.
Some far galaxies are traveling from us much faster than speed of light because of space expanding. Thus theory of relativity will work correctly for distances less than 1B of light years, but it is not correct for larger distances. Are you agree?
