    "abstract": "In order to clarify why the zero-point energy associated with the vacuum\nfluctuations cannot be a candidate for the dark energy in the universe, a\ncomparison with the Casimir effect is analyzed in some detail. A principle of\nepistemology is stressed that it is meaningless to talk about an absolute\n(isolated) thing. A relative thing can only be observed when it is changing\nwith respect to other things. Then a new conjecture of antigravity --the\nrepulsive force between matter and antimatter derived from the modified\nEinstein field equation in general relativity-- is proposed. this is due to the\nparticle-antiparticle symmetry based on a new understanding about the essence\nof special relativity. Its possible consequences in the theory of cosmology are\ndiscussed briefly, including a new explanation for the accelerating universe\nand gamma-ray-bursts.",
