<p>Since we are pretty sure that the universe is expanding at a steady and accelerating rate wouldn’t it be possible to simultaneously observe 4 points (galaxies) that are all, as closely as we can tell, at a similar distance from our reference point to triangulate back and find the beginning point or location?</p>

as discussed in [Why can't we determine the center of the universe](https://astronomy.stackexchange.com/q/5978/7982) and [What is in the center of the universe?](https://astronomy.stackexchange.com/q/669/7982), current thinking is that the universe is much bigger than the *observable universe*, and since rate of expansion increases with distance from us, going outwards things get redder and dimmer and then finally become unobservable. However we don't know just how much bigger the whole universe is than what we can observe.

Has any astronomer/physicist used geometry and trigonometry to calculate where the center of the universe is?
