No, they are working with alternate beginning states and conditions to see if it better explains what we currently observe...
...did I do that right?
No, General Relativity is a 4-diminsional theory worked out by Albert Einstein with the input from many other very brilliant individuals whom one hardly hears about, ever. And, so, x0 is the time axis (at least in some GR texts), followed by x1, x2 and x3. In eternal Universes, the time axis runs from minus infinity to plus infinity, and so, those models are eternal without a beginning and without an end.
