Abstract: | We investigate the gravitational time delay of light in the Schwarzschild black hole space-time surrounded by quintessence. With the analysis and numerical methods, we find that the
gravitational time delay of light in the Schwarzschild black hole
space-time surrounded by quintessence increases when the normalization factor c increases, and that the gravitational
time delay also decreases when the quintessential state parameter
ωq increases. |
