No. This is absolutely false. Science moves forward through being able to figure out better and better how reality works.

While this completely true, and consensus only plays a minor role in science, it's not true that consensus is irrelevant. Given no other information about a certain hypothesis other than that the majority of scientists believe it to be true, the rational course of action would be to adjust belief in the hypothesis upward. Of course, evidence contradicting the hypothesis would nullify this consensus effect. Even a small amount of evidence trumps a large consensus.
