So now you're saying that it's impossible to actually contact a scientist. Nice. Where can you find a scientist? At the nearest university/college. Doesn't take a genius to figure that out. It's not hard at all to find out where one is, and most cities have at least one, even if it is a smaller one.
And what you've described isn't at all what you've originally claimed. What you originally claimed in OP was, and I quote: "These people have backed up these claims when they were able to predict outcomes of the future."
You're now telling me that they can't, and haven't, backed up these claims.
So what's your endgame here, to instead of provide actual evidence that this is true, say that I "can't disprove" what you've said? Because that's all you've been implying so far.
