It appears curved to us because we mathematically transformed the reference frame.
If you are allowed to transform your geometric space to say “no straight lines” then there are no straight lines in math either. Because you could perform a transform on the straight line into a curved geometry.
“I want to emphasize that light comes in this form-particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you were probably told something about light behaving like waves. I’m telling you the way it does behave- like particles.”

Neutrinos travel in a straight line.
Unfortunately (fortunately?) the space they’re traveling through is curved. It was a good attempt though neutrinos.
Edwin A. Abbott has entered the chat…
Not to mention quantum fuzzing

They don’t, although they
do not“rarely” interact with other particles, they move as waves, like all other energy in the universe.“I want to emphasize that light comes in this form-particles.

You’re talking to somebody that studies particle physics okay.
