This page of the trophy guide to Death Stranding has a detailed description of God Particle Go-Getter trophy. This bronze trophy is awarded for finding and visiting Higgs' home.
The earliest you can get this trophy is after completing chapter 9 - after you have defeated Higgs in a boss fight. Go to Peter Englert's house located in the central region, west of Lake Knot City.
Look for a small building next to two tanks.
Enter the building. The entrance to an underground bunker is behind the terminal.
Enter a room with numerous notes hanging on the walls. Wait a moment for the trophy to unlock.
