One of the most fundamental problems in the history of humanity and the very basis of the notion of relativity of simultaneity: how to synchronize two watches so that they give the same time at the same present moment?

 What do you mean by "hyperlane"?

The set of all points, which could be connected to an events by a hypothetical signal with infinite velocity builds actually a three dimensional space.
In RT-lingo, this is a hyperplane (of the present).
Imagine you would 'flatten' space to a 2-dimensional sheet.
