Why is it that the scientific community will accept ideas that are only a few years ahead of their time, but they won't even consider ideas that are hundreds of years ahead of their time? Why won't they listen to people without Ph.Ds?

People on the Internet come up with a lot of good ideas all the time, why not consider their ideas instead of only drawing from a pool of Ph.Ds? What could be more profitable than the ability to communicate with the future? Yet, if you try to talk to a scientist about this, they will ignore your calls and emails. No one wants to spend any money on experiments in temporal mechanics because of its association with science fiction. The concept for teleportation has more acceptance in the scientific community than the concept of negative mass neutrinos, even though one is an awful lot more plausible than the other.

It's not just academia. Forums such as this one will immediately pooh-pooh such a notion as do the non-futaba scientific boards. Even if a person has a lot of other good ideas that are actually meted out, any idea having to do with the concept of contact with the future is ignored.

Explain this.
