Not true, as I said previously, most supernatural phenomena HAS been identified as something quantifiable, which is why most scientists don't concern themselves with studying it. It is a dead-end field (Sorry Ghostbusters, but we still love you). Here are some enlightening links for all you pro-ghost people to visit, including DCTP's version of this topic.
First on the list...
The Shady Science of Ghost Hunting You can read the first half of it, but really, the real brunt of the article in relation to our discussion starts at "Devices that don't work" and more importantly "Reality Check." Really I think they could have applied the concept of Occam's Razor to add another dimension, but hey, its a good article regardless.
Now the next two are Cracked articles, slightly less legitimate, but they do usually do their research and mention many good things.
The Creepy Scientific Explanation Behind Ghost Sightings The title says it all..

It explains actual ghost sightings.
Last but not least, DCTP's thread
DCTP's Do you believe in ghosts thread Feel free to read both sides, but pay special attention to Jd-'s posts. BTW, that is also where Kleene defends her position AGAINST Jd-. Quite interesting really... Also, that is why I don't feel the NEED to go after Kleene's beliefs, I've already done it once before accompanied by Jd- and Abs. if I recall correctly.
Now to those of you who are likely thinking, "BUT KYUU! WHAT ABOUT ALL THOSE GHOST SHOWS WITH VIDEO EVIDENCES!?!?!?!?!" Well... Here are two links that you should likely read up on Pepper's Ghost.
Also this is a fun video! More camera trickery!
There is plenty of videos, articles, and so fourth that PROVE that it isn't a ghost, but YOU placing a "ghost" there. I would be harsher with my words and tonality, but I'm trying REALLY hard not to be mean with this.
If you consider that first link I posted and the fact that it explains that those ghost hunting devices don't work, combine it with the two Cracked articles, and throw it into the mix with Pepper's Ghost, EVERY SINGLE LAST GHOST SIGHTING IS EXPLAINED! And if they aren't there is something called "lying," because lets face it, every ghost story is anecdotal and is NEVER replicated.
As for there being phenomena that is unexplainable by science, sure there are things that are left unknown by science, but none of them are supernatural, because EVERY supernatural phenomena is ANECDOTAL and NOT REPRODUCIBLE. The things that I know science can't explain, and my genetics professor jokingly said that those things were "magic." And when you think about it that is not entirely untrue. The natural world IS magical when you think about it, but not because it is supernatural, but because it can do things that humans have been unable to replicate, or cannot figure out as of yet despite countless hours of research and grant money put into solving the issue. None of that means that they aren't unexplainable, but that we don't have the tools necessary to explain them yet.
But again, feel free to prove me wrong and collect that one million dollar bounty, and remember to check the log of applicants.
Enjoy this long information filled post. Naturally you are entitled to believe what you want, but until you can prove it, don't try and convince anyone that ghosts exist, because there is NO evidence of them existing, but plenty of evidence DISPROVING ghost SIGHTINGS and ghost RELATED phenomena (please note that I never said science disproved ghosts, as stated, it hasn't and probably won't because there are more important things to study and no one will fund that research)
Now I'll believe in ghosts when someone can show me some hard evidence of them existing, I have the same policy with ALL supernatural things. I don't discount any possibilities, but I don't believe anything until I can see tangible evidence of it.
tl;dr: All signs point to ghosts NOT existing. The possibility remains, but until science can prove it, they don't. Funny thing about that is if science does prove it, not only will it not be supernatural, but a name will be affixed to it that will likely not be ghost because it will be connected to a natural phenomena. But as it stands all "evidence" of ghosts and supernatural phenomena hasn't stood up to even the slightest scrutiny.
