If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.

If we could travel into the past, it's mind-boggling what would be possible. For one thing, history would become an experimental science, which it certainly isn't today.

I have no idea whether it's possible, but it's certainly worth exploring.
