To "what exists today, beyond 13.7 billion light years", I'd rather say that "it doesn't exist yet". Because, otherwise, it assumes there's some "global universe time" like UTC or something. But all there is is our light cone.

By definition there is no causal connection. I’ll get back to you on that once I finish inventing my Time Machine.
