there's no proof a planets swings into our inner solar system?
Sometimes proof isn't found, it's realized!
In the case of an unknown planet it is demonstrable that there is no missing mass in the part of the solar system where the known planets orbit.
Therefore, no unknown planet can have an orbit that enters the orbits of the known planets.
There was NO proof the Sun was the center of our system back in the days. It was assumed due to critical thinking.
Same with our tenth planet. Nibiru. Or Nemesis. Or Tyche. Or whatever.
You're quite mistaken here. The geocentric universe was early on seen as a problematic system. There were many problems with the system and
heliocentric systems had been proposed early on.
In 1610 Galileo made 3 important observations that made the case, quite clearly in fact, that the geocentric system was dead. It was known to be a bad
idea for well over 1500 years. Galileo observe a comet, Venus had phases, and the Galilean moons showed that the Earth was not at the center of the
Is there an undiscovered planet? There might be. But what do we know about it. The evidence is very clear that any undiscovered planet is going to be
very far out from the sun and it will have an orbit that never enters the orbits of the known planets.
Nibiru is a fantasy of a crank that sold hoaxes to fools.
Nemesis was a prediction based on a perceived periodicity to extinction events.
Tyche is a prediction based on comets believed to originate from the Oort cloud.
There might be a brown dwarf, but the likelihood is rather small now. The possibility of a new planet is not that good either, but if it exists it
must be really far, far away.
