how do scientists explain ghosts? What do they have to say about them.. do they exist or not?

One of the hardest thing that scientist have to deal with is the existences of ghost............ Now most scientist knows how a ghost is created but it is one of the hardest things to explain to the general public understanding........ Now all a ghost really is a piece of energy that the human brain give off in it fight to survive death........ By as to how or why the human brain does that still remains unexplained for after all of these centuries there is still a ton of things that scientist just don't know about the human brain........................... So they just leave so many thing about the human brain unexplained period........................

The very reason a topic is considered to be 'paranormal' or 'supernatural' to begin with is because they lie outside of the scope of science, by definition, so there is no scientific explanation of them. How do scientists explain ghost reports? Many of them are fabrications, stories made up by people for attention or notoriety. Most of the genuine 'ghost sightings' are hypnagogic hallucinations, people who wake up at night and think they see a figure in their bedroom that disappears after a few seconds--those are related to sleep and dreams, and aren't paranormal at all. In many cases no 'ghost' is seen at all, but superstitious people hear sounds they can't identify and just assume they are ghosts without looking for a real-world cause.

There is no convincing and compelling evidence that ghosts exist.

Few scientists even believe in ghosts, and none of them have any explanation for them.

Even for scientists who believe in ghosts, they can't really study them. No one has ever brought a real live ghost into a laboratory to be studied, and that's what scientists need. Scientists can only begin their research if they have something in front of them to be studied, and a what-if theory isn't enough.

If they exist, scientists have not found any credible evidence they accept.

Most of the parapsychology studies that attempt to prove ghosts have been debunked by scientists, or are seen as highly questionable rather than a confirmation of anything.

No. And scientist explain them as self-induced phantasies.

I'm a christian, and no ghosts are not real.

Demons are but they're rare. Angels are but never show themselves.

You're ugly.

the paranormal studies is still all meta. but i am intrigued by ghosts.
