Why can't my headlights shine more than 160 feet in front of me, but stars can emit light that travels allllll the way the fuck to us here on the earth... I understand that on earth, there is atmosphere and whatnot that scatters and stops the light from shining further, but isnt starlight travelling through arguably much more atmosphere to shine all the way the fuck to my eyes? I mean- what the fuck- Why do people believe this shit? Can someone explain to me why I can see starlight from billions of miles away?

can you also explain how, while we are spinning and spinning and all the shit in space is spinning and spinning, and the space is growing and expanding, how that FUCKING STAR light keeps pointing in a perfectly straight line to us on earth? Even though light is very easy to diffuse here on earth. Just wondering why what we actually observe about light on earth DOESNT appy at all to light in space. Would literally love a good explanation that isnt some religious mumbo jumbo about muh science.
They don't. A spherical source of light "points" in all directions
