If you are here asking: "Is this a science meme?"
Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.
Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.
We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.
See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

they do tavel in a perfectly straight line though.
space time is curved, not the light path.
What about the fact that light bends around corners? Notably the interference pattern when shining light through a slit?
False because they are affected by gravity, even if ever so slightly
But isn't the gravity bending the space, so the light itself is travelling straight but seems curved to the observer?
Hmm, I’m not actually sure. Are we also ignoring refraction and reflection because the path is straight between those? If we’re talking discrete photons, you may be correct about each segment in its path being perfectly straight, but I’m not a theoretical physicist.
"through vacuum"
gravity isn't a force, it's the curvature of space-time itself.
light follows a perfectly straight line through vacuum. the space itself isn't straight.
like drawing a straight line on a flat paper, if you roll the paper, that line is still straight within it's medium.
Newtonian gravity has been replaced by General relativity, and has been proven to be the correct model (at least more correct than Newtonian gravity).
Makes sense to me. Thanks
