So wormholes are nothing more than a crackpot theory promoted by Hawking and other “non-crackpots”?
Wormholes, as of yet, have no experimental evidence in their favor. As such, they are an unproven hypothesis. That is NOT the same as crackpottery because they are based on other theories (like General Relativity) which have solid backing. There is nothing wrong with speculation as long as you acknowledge that's all your doing.
One day they might be proven to exist. If they were, it would be awesome.
But everything else (with the possible exception of dark matter) is “totally correct, confirmed and understood” which means none of it will ever be ever proven wrong?
It is possible. Not likely in my opinion but still possible.
Even if they were, what of it? That's what science does.
If just one of these things is ever proven wrong will you classify yourself as a crackpot that shouldn’t be listened to?[/quote]
Nope. You can believe something for good reasons or you can believe something for bad reasons. If you do the former, you are normal. If you do the latter, you may be a crackpot.
Even if the electric universe hypothesis is proven to be true at some point in the future, the truth remains, there is no reason to believe it NOW.
Wasn’t Einstein and his Relativity theory once considered to be “crackpot” by many “non-crackpots”.
I think you misunderstand the term "crackpot". A "crackpot" is someone who postulates an idea that is at odds with decades of solid experimentation
without good reasoning. Einstein was not a crackpot because he speculated on relativity, suggested ways of testing it, and was found to be right in short order. That's bad ass physics, not insanity.
I have no doubt that some experts thought Einstein was wrong. That is no sin. Without experiments to back it up, relativity was just a hypothesis. Unproven and disproven hypothesis (like the electric universe) become "crackpottery" when it is held despite all good evidence to the contrary.
On another note, remember this:
Carl Sagan said:
...the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright Brothers. But they also laughed at Bozo the Clown.
