although we couldn't prove that these ghost or apparations are there, we can't really proof that they do not exist as well.
i agree that the psychological and mental state of a person does play a significant role in the so called alleged ghost sightings, but can we really rule out the possibility?
modern science may have an explanation for almost all of these paranormal events, but we should see it from both perspectives. probably thats why research is going on and there are many so called ghost hunters out there.
in my opinion.. given enough time.. modern science will probably be able to dissect these ghosts and soon offer an explanation.

well u may be right there. but comparing the concept of ghost to an invisible purple elephant is hardly a fair comparison.
There are a good number of people out there who have felt the presence of ghost or even seen them. Not just one or two.
In addition to that, modern science has not offer any reasonable theory to proof that what these people have seen aren't ghost.

if, we are able to successfully measure ghost, we may have more insight into how it is generated. following the step wise process of science, which include observation, hypothesis, manipulation, reproduction and inference. we may just be able to manipulate its energy and reproduce it from the insight we have gained from "measuring ghost".

i'm well aware of the external factors.
But what i'm merely voicing is just my opinion.. and like i've said in my previous post.
i believe that it is a natural phenomenon, their existence, it isn't anything paranormal.. and given time i'm sure science will get to the bottom of it.
its out there.. we just don't know what it is..... yet.

those "nerds" aren't trying to prove something.
experiments are going on to discover new knowledge, cures and remedies, ways to enhance our lifestyle.
imagine a world without scientist and doctors? those "nerds" are the very foundation of mankind.
if every1 chose not to believe in science and the "nerds", this world would still be in the stone age.
if it takes science 500 years to prove , your descendants and the rest of mankind will have the benefit, so its not a total lost.

if science could heal every disease then wouldn't mankind be playing god?
there are many incurable diseases in these world, most of them are congenital.. and some lay dormant and manifest at a later stage of life.
these things are out of our control...

in addition to that, i don't think there is anything called as a "non science" method, even in alternative medicine.
its a stepwise process, first comes observation, next comes hypothesis, experiment, reproducibility, inference.
every person has a choice, if they opt for alternative medicine they are free to do so.. "they don't have to wait for science to proof it could be healed"

finally, to believe in the advancement science and to believe in a different kind of existence (ghosts) differs from people to people.
skeptics tend to look for a scientific explanation.. (though there isn't really 1)
while believers think otherwise.. but it isn't fair to disregard the other fields of science.
science is such a general and broad term. it covers, medicine, mechanics, aviation, ai , etc..etc..
i myself think that paranormal science and studies hold very little significance.. however, i do believe that the other fields of science has benefitted mankind in many ways.

it is a possibility that modern science may be capable explaining ghost.
i've not totally discounted the idea. its just that i feel that its of little significance.
if you've read my earlier posts. i did mention that given enuff time science would probably advance to a point where we could even dissect ghosts.

if its me between life and death, all you could do is make wats left of your life worthwhile. i would understand that... and i stand firm with what i say.
i'm a medical student myself, and i know that doctors aren't gods that can heal all diseases.
there's only so much a man could do..

i've never said i don't believe in ghost, i've mentioned before in previous post that i believe that the existence of ghost itself is a natural phenomenon.
and when i mentioned about playing god. i meant it as a metaphor. don't take it literally.
