Many diagrams show light cones tipping over when closer to a black hole singularity, such that emitted light can have a downwards (negative time) component in the distant observer coordinate frame. e.g this diagram:(adsbygoogle = window.adsbygoogle || []).push({});

or this one:

or this one:

However, other diagrams show that the light cone gets narrower towards the singularity, such that it looks like it emissions never have a downwards component:

So my question is, which version is correct? (for a Schwarzschild black hole, using coordinates of an observer at infinity). Can the light cone ever have a -t component in the distant observer's t coordinate?
