Only scientists please, How can we know if planet x exist or not?
Knowing this information, how can we really know how truth it is this matter? Some people, said it's not real, some people said it's real, I wish to start my own research, if you were me, how can you start your own research to know the truth? I live in California, but I know that the telescopes in some universities are available to make research just for professors, any advice? I have an open mind and just I want to know the truth, no because someone tell me that is truth or not, if not because I want to be a witness. Thx
