Can Black Holes Absorb Massless Light?

Click For Summary
SUMMARY

Black holes can absorb massless light due to the principles of general relativity, which state that mass and energy curve spacetime. This curvature causes particles and photons to follow paths that lead into the black hole, demonstrating that mass is not a prerequisite for absorption. The discussion emphasizes that the gravitational force of black holes is sufficient to influence light, despite its lack of mass. Understanding these concepts is crucial for grasping the nature of black holes and their interaction with light.

First of all, I have to say that I'm not sure if my post is on the good forum. If there's any problem about that, just tell me where i should post it.

So my question is, why light can de be absorb by black holes if light has no mass. I mean if black holes have enormus gravitational force it still need to have an object with mass to be absorb?

Thanks

In general relativity (the more modern theory of gravity) mass/energy (such as a black hole) curves spacetime. Things (particles, photons, etc.) follow paths in the curved spacetime. This can be manifest as a black hole absorbing light. No photon mass is necessary.
 
Um...I think this was an easy one for you. Thanks. I will review Einstein Theory of relativity.
