I don't think that it's a big problem as such - the cases are fairly few, and don't stand up to moderately careful scrutiny by someone who knows what they're talking about. By the very nature of research, you're always going to get questionable papers - it's what fuels scientific debate, the quest to discover workable new theories first. People publish papers that turn out to be incorrect every day.yougene said:It does seem to be a big problem these days as I have heard of more then one such case in the past year. It really makes you wonder how much of this stuff is completely fabricated.
It does, however, highlight that modern physics and mathematics is becoming so specialised that you often have to be an expert in the field to make head or tail of it.
I'm not sure how much it's a modern problem though - when Einstein's GR was published, you hear that there were only a dozen or so people in the world who understood it. Now I'm not sure how true that is; I suspect there were more; but today GR is something that's lectured to 3rd year physicists and mathematicians. Thousands of students graduate every year with a working knowledge of Einstein's Relativity. What was once the cutting edge of physics is now undergraduate material. I suspect that the same will happen with current cutting edge research - I could definitely see subjects such as String Theory, M-Theory etc being taught at undergrad level when/if they become accepted.
