Scientifically, what could the aliens look like if they really exist? Images are welcome.

 Exist ghosts really?

You're not the only one who thinks that ghosts exist. Worldwide, there is a belief in spirits that continue to exist after death in other worlds. In fact, among paranormal phenomena, ghosts are among the most frequently accepted. 

Numerous people are fascinated by ghosts, and thousands peruse the daily ghost stories on Reddit. It goes beyond simple entertainment; according to a 2019 Ipsos research, 46% of Americans genuinely believe in ghosts. 

Only 7% of respondents indicated that they believe in vampires, demonstrating the nation's discriminating undead views.

The notion that the deceased stays with us in spirit is a long-standing one that may be found in various tales, including "Macbeth" and the Bible. 

Even the folklore genre of ghost stories was born from it. A larger web of related paranormal beliefs, such as those about near-death experiences, life after death, and spirit communication, includes the belief in ghosts. 

Who wouldn't find comfort in the idea that their cherished but deceased family members aren't watching out for us or there for us when we need them?

People have been attempting to (or claiming to) converse with spirits for millennia; for instance, upper-class ladies in Victorian England had séances in their parlors following tea and crumpets with friends.

At famous institutions like Cambridge and Oxford, ghost clubs dedicated to looking for paranormal evidence started to emerge, and in 1882 the Society for Psychical Research, the most well-known group, was founded. 

Eleanor Sidgwick was a member of the team as an investigator and subsequently as its president; she is regarded as the first female ghostbuster. 

Many psychic mediums in America in the late 1800s professed to communicate with the dead, but skeptics like Harry Houdini ultimately exposed them as frauds.

Ghost hunting didn't get international acclaim until quite recently. The popular Syfy cable TV program "Ghost Hunters," which broadcast 230 episodes but failed to uncover any solid proof of ghosts, is largely to blame for this.

The idea of the program is that anybody can seek ghosts, which is why it has inspired dozens of spinoffs and imitators. The two initial stars were just regular guys—plumbers, in fact—who made the decision to search for signs of ghosts. 

They are saying that you don't have to be a brilliant scientist or even have any background in research or science. All you need are some idle time, a dark location, and perhaps a few electronics shop devices. Any inexplicable light or sound might be proof of ghosts if you investigate closely enough.

Part of the reason why there are more myths about the afterlife than ever is because of the nebulous criteria for ghostly occurrences.

The logic and science of ghosts

The fact that a very wide range of occurrences, such as a door shutting on its own, lost keys, a chilly spot in a corridor, and visions of a deceased relative, are attributed to ghosts makes it difficult for scientists to evaluate them.

For their 2016 book, sociologists Dennis and Michele Waskul spoke with people who had had ghost experiences "They discovered that "many participants were not sure that they had encountered a ghost and remained uncertain that such phenomena were even possible, simply because they did not see something that approximated the conventional image of a "ghost" in Ghostly Encounters: The Hauntings of Everyday Life (opens in new tab)" (Temple University Press). Instead, a large portion of our respondents only believed they had encountered something strange, unusual, spooky, or intriguing."

As a result, many persons who publicly state that they had a ghostly encounter didn't necessarily see anything that most people would consider to be a conventional "ghost," and they may have really had entirely different experiences with the sole exception that they couldn't easily explain them.

Personal experience and scientific proof are two different things. There is no one, accepted definition of what a ghost is, which contributes to the challenge of examining spirits. 

Others contend that ghosts are telepathic beings that are projected into the world from our brains. Some people think that ghosts are the spirits of the deceased that, for whatever reason, become "lost" while traveling to The Other Side.

Others still divide up different kinds of ghosts into their own unique subcategories, such as poltergeists, persistent hauntings, intelligent spirits, and shadow people. Of course, it's all conjecture, just like speculating on the various fairies or dragon races; there are as many different kinds of ghosts as you want.

Ideas regarding ghosts contain a lot of paradoxes. Are ghosts, for instance, real or not? Either they can smash doors shut and fling things across the room, or they can pass through solid objects without affecting them. 

It must be either one or the other based on logic and the principles of physics. If ghosts have human souls, then why do they frequently show up wearing clothes and carrying seemingly soulless items like hats, canes, and dresses? This is in addition to the numerous stories of ghost trains, vehicles, and carriages.

Given that ghosts are claimed to speak with psychic mediums and should be able to identify their perpetrators for the authorities if ghosts are the souls of those whose deaths went unpunished, why are there still unsolved murders? The concerns are endless; virtually every claim made concerning ghosts is met with logical objections.

To find the ghosts' presence, ghost hunters employ a variety of inventive (and shady) techniques, frequently involving psychics. Most ghost hunters who claim to be scientific appear to be such because they employ high-tech scientific tools like Geiger counters, Electromagnetic Field (EMF) detectors, ion detectors, infrared cameras, and sensitive microphones. 

Virtually all ghost hunters make this claim. However, no one has ever demonstrated that any of these techniques can genuinely find ghosts. Flames were thought to turn blue in the presence of spirits for millennia. Few people now believe that item of folklore, but it's probable that many of the signals used as proof by ghost hunters today will be viewed as equally false and out-of-date in decades to come.

Others contend that because we lack the technology to locate or identify the spirit realm, ghosts have not yet been confirmed to exist. However, this can't also be true: Either ghosts exist and manifest in the real world, where they may be seen and captured on camera, on film, on video, and in audio recordings, or they don't. 

We ought to find concrete proof of the existence of ghosts if they are capable of being observed or documented scientifically, but we don't. If ghosts exist but cannot be observed or captured using scientific methods, then none of the images, recordings, and other media that have been used as proof of ghosts can be true ghosts.

It's hardly surprising that despite the efforts of thousands of ghost hunters on television and elsewhere for decades, not a single piece of actual proof of ghosts has been unearthed given the abundance of fundamentally incompatible hypotheses and the paucity of relevant scientific research.

And of course, it's now simpler than ever to produce and distribute visually eerie photos on social media thanks to the recent release of "ghost apps" for smartphones, making it increasingly harder for ghost hunters to distinguish truth from fiction.

Why many think

The majority of people who believe in ghosts do so as a result of a personal encounter; they may have grown up in a household where the existence of (friendly) spirits was taken for granted or they may have had an unsettling experience while on a ghost tour or visiting a local haunt. 

However, a lot of individuals think that evidence for the presence of ghosts may be found in current physics, which is a rigorous science. It is popularly believed that Albert Einstein proposed a scientific theory based on the First Law of Thermodynamics to support the existence of ghosts: 

What happens to the energy in our bodies after we die since energy cannot be generated or destroyed but can only change form? Could that possibly appear as a ghost in any way?

Cathy Anne Hello? What do you resemble? I can't hear you, so speak up! In the United States, Poltergeists had a role in defining a paranormal culture.

Until you investigate the fundamentals of physics, it appears like a plausible assumption.

The solution is not at all mysterious and is really straightforward. The energy in a person's body after death enters the environment, where the energy of all living things does. 

The body is transported into the creatures that devour us (i.e., wild animals if we are left unburied, or worms and germs if we are interred), the plants that absorb us, and the energy is released in the form of heat. Nobody's "energy" that survives death can be picked up by common ghost-hunting equipment.

Even though amateur ghost hunters prefer to think of themselves as pioneers in the field, they are actually partaking in what folklorists refer to as "legend tripping" or ostension. It essentially consists of individuals "playing out" mythology, sometimes one with ghosts or other supernatural beings. 

his book "Folklorist Bill Ellis notes that ghost hunters themselves frequently take the search seriously and "venture out to challenge supernatural beings, confront them in consciously dramatized form, then return to safety" in "Aliens, Ghosts, and Cults: Legends We Live" (University Press of Mississippi, 2003). Such activities explicitly say that their goal is to test and establish the bounds of the "actual" world rather than to provide amusement."

If ghosts are real and represent some kind of as-of-yet-unknown energy or entity, then their existence will—like all other scientific discoveries—be discovered and verified by scientists through carefully designed experiments—not by weekend ghost hunters prowling around supposedly haunted homes in the dark at odd hours of the night with cameras and flashlights.

In the end, the evidence for ghosts is no stronger today than it was a century ago (and this is despite masses of questionable photographs, sounds, and movies). There are two reasons why ghost seekers might not have found any solid proof. 

The first is that ghosts don't exist and that psychological effects, false impressions, human error, and hoaxes can account for tales of ghosts. The second possibility is that there are ghosts, but there is no conclusive proof since ghost hunters lack the necessary scientific equipment and attitude.

However, in the end, ghost hunting is not really about the proof (if it was, the search would have been abandoned long ago). Instead, it's about having a good time with friends and family, sharing tales, and enjoying the act of pretending to look for something out there in the unknown. Everyone enjoys a good ghost story, after all.

A study in the British Journal of Developmental Psychology suggests that while youngsters are inclined to believe in the existence of imaginary animals, experiments demonstrate that they can discern between fantasy and reality.
