Relativity is theory. We are talking about real world. We already know, that vacuum can generate particles, thus it is not completely empty: http://scienceblog.com/40901/theoretical-breakthrough-generating-matter-and-antimatter-from-the-vacuum/ http://scienceblog.com/40901/theoretical-breakthrough-genera...

Relativity describes the real world. You seem to want to talk about theoretical ideas that have no evidence. 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. 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.

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?

    "But you cannot produce particle using just energy." Yes you can. And no I don't agree with your last sentence.

      No, you cannot. Do you know about Big Bang?

        What do you want to know about the Big Bang? And why in the world do you think you can not produce particles using just energy? It happens all the time.
