No Stupid Questions@lemmy.world•Do straight lines and flat planes exist in nature?
1·2 years agoMy understanding is that in a true vacuum light will not be reflected or bent by particles. However, due to gravity bending space time itself, light will follow the curvature of space. It would depend on the observer if the path if light is straight. If you look at the light passing by, it would not be straight under influence of gravity. If light itself is the observer, it will travel in a straight line :)
In the case of gravitational lensing the observer is looking at light coming in. An outside perspective.
I have been learning some database stuff today. Finally understand the drop table thing better.


On a planet as diverse as ours, there should be plenty of room for both regular sports and e-sports.
