Yeah, why do so-called scientists say something is impossible and then not offer a theory to explain why it's impossible. For instance, if a theory was out that earth has a twin that stays on the exact opposite of the sun all the time, a scientist could cite the nonexistence of gravity pertabations on Mars and Venus to prove that theory wrong. But when a theory comes out that a large object is orbiting in the Oort cloud, why do "scientists" dismiss it without being able to disprove it? It doesn't seem very scientific to me.
