First, there's a lot of science that's done without "experiments".
Second, the problem with significance is it's pinning "not just some random noise" to an arbitrary threshold. Results with a p-value of 0.051 and those with a p-value of 0.049 are effectively the same, and yet are treated as if they're worlds apart.
