Assume there's no atmosphere, and you turn on a flashlight at night. Shouldn't the light be visible from a million miles away?

So the light travels in a straight line but the curvature of the earth prevents it from lighting up surfaces 100 miles away?

that's not it at all. trust me bro, you need to get a 1mm mile stretch with no atmosphere and try it and you'll see.

Photons are less interactive with our fabric of space time than solid matter. So in effect they are less grounded in reality actually.

In a vacuum, it does. But irl the light will likely collide with other particles convert into heat energy and disperse.

These people will tell you that if you're riding a bike and shine a flashlight, the light will have the same speed as it would if you were standing still. Physics is like some weird cult
