I was refering to this: "We have to be careful of the statement that science has to consider all possibilities."
Theoretical physics, the maths, arent always right (any tool can be used inccorectly), they have to be proven by experiment. And I believe that the examples I gave were rarely considered possibilities. Einstein could have looked at his relatavistic equations and tossed them, thinking it was impossible, he had to consider all possibilities. And at the same time he didnt believe in quantum physics.
So I believe science dose have to consider all possibilities, but there are many that are easy to rule out.
