Using a hypothetical photo from a hypothetical telescope, we were able to determine that the farthest galaxy present in the photo is 1 billion light years away. Because we are awesome we were able to also tell which direction all the galaxies in the pic are moving. We are also capable to estimate the mass of the galaxies.
In possession of these information aren't we capable to locate their "source", aka the local of the big bang? In another words, can we, in possession of objects current position, mass and relative speed tell where they were?
