Yes, yes, I know how clickbaity the title seems, but hear me out. I have discovered the method of which we can find the Thargoids. "How?" you ask? The answer is surprisingly simple. Biochemistry. You see, the game developers at Frontier are incredible with their attention to detail. David Braben is a god amongst game devs. So, how does biochemistry tie into the hunt for the Thargoid homeworld? Glad you asked.
It says on the wikis that Thargoids are carbon-based like humans. However, their solvent is ammonia, where ours is water. The devs have cordoned off a bunch of regions of space. So, my mate and I realised all we had to do was make a 50 million year timeframe (the generous guess for how long it took for a star system fo kinda, sorta form). We would do this by getting the average birth year for stars for each region. That's the beginning of our timeframe. Then, we have to add 50 million years for the end of our timeframe. Then, we can use magic to figure out what elements were abundant in that timeframe.
Since Thargoids happen to have ammonia as their solvent, we know the air must be stuff that is a gas between -78 and -33 Celsius. This leaves us with 11 elements if we're being generous. So, we can cross off 2 of them (radon and fluorine) for obvious reasons. 1 of them (krypton) could potentially be crossed off but we're not certain. All we have to do is pick the most suitable candidates. From here, we can narrow our search to areas within those regions. This could limit the search from hundreds of millions of stars to just a few hundred.
This is just a fraction of the work I've done in studying them. I've got theories to explain most of the mystery behind them. You can ask me questions if you want the dirty deets on that stuff, though.
Ciao for now.
