Abstract: | It is shown that quantum vacuum fluctuations give rise to a curvature of space-time of the order appropriate to explain the
observed accelerated expansion of the universe. The fact that the fluctuations produce curvature, even if the expectation
of the vacuum energy vanishes, is a consequence of the non-linear character of the Einstein equation. A calculation is made,
involving plausible hypotheses within quantized gravity, which establishes a relation between the two-point correlation of
the vacuum fluctuations and the space-time curvature. |
