If light gets attracted by gravity, how does it manage to travel to the Earth despite the Sun's large of amount of gravity?
Okay, so if light is not affected by gravity in the same way as objects with mass, does that mean it doesn't experience time dilation or redshift?
Light does experience time dilation and redshift, but they are caused by different physical mechanisms. Time dilation occurs due to the relative motion between an observer and the light source, while redshift occurs due to the expansion of the universe.
