I myself do not know the answer, being this is the first night I've ever been interested in physics and space in general, I shouldn't.. BTW, I'm new to the forum.. But I don't feel his questions on light or gravity, I'm not sure if it's an avoidance of the question or you're just not understanding it.. Let me rephrase if I'm understanding correctly... Does brighter light move at a faster pace than dimmer, less powerful light?? And for the gravity question.. In two different gravitational scenarios, You have object (1) , considering objects have a maximum velocity we'll say the distance between the two points (A) and (B) would end before maximum velocity is reached.. Ok, on Earth object (1) is dropped from a resting position from point (A) to (B) and the same expirement is performed on the Moon, the Moon being the only variable.. Would the stronger gravitational pull create a higher velocity in object (1) between points (A) and (B).. While typing this I've come up with a question of my own... Does the strength of gravitational pull determine an objects maximum velocity??? If I sound terribly uneducated, my schooling ended in the 9th grade. Thanks
