How the fuck does light that has no mass still bend near a star?
Added 2025-08-21 17:50:22 +0000 UTC In Newton’s classic gravity works only on masses. So for a long time people thought light doesn’t give a fuck about gravity.
But Einstein said you think wrong.
Gravity is not a "force" that pulls something. It's the shape of space time itself.
Light always goes on the most "straight" path only the thing is in curved space the "straight" path can look curved.
In GR(General Relativity) this is called a geodesic.
I will tell about them next time.
So the photon does not "feel a force" and is not "pulled" anywhere. It just goes straight. But space itself bent and its trajectory now looks curved.
Example: An ant on a trampoline. It always walks straight on the fabric but if the fabric is sagged under a weight it walks "curved". The ant does not actually turn but for you from above it looks like it "turned".
Light is the same ant just without legs...
Light is an ant without legs...👀
I will reply for all messages and comments tomorrow
I got sick🥲

Unfortunately it's not my idea about gravitation:(
