How to leave a trace without affecting the normal development of this primitive civilization, while also enabling them to help themselves in the future, requires skill.
As it happened, Tom explored this solar system and unexpectedly discovered an asteroid with a rather peculiar orbit.
The longest part of this asteroid reached 50 kilometers, and its total mass was as high as 20 trillion tons. According to Tom's calculations, in about 500 years, there was a probability of over 95% that it would collide with that planet.
The impact of an asteroid with such high mass and such a large volume would unleash tens of times more energy than the asteroid that wiped out the dinosaurs.
And according to the trajectory of normal development, it was almost impossible for this civilization to have the ability to stop this asteroid impact after 500 years.
The ultimate demise of this civilization seemed inevitable.
However, now that Tom had arrived, the course of events was naturally different.
