Trick or treat...

They’re spooky. They’re scary. And they’re probably not real. But what if it was confirmed that ghosts were living among us?

Should we be worried? What would they be made of? And who ya gonna call?

So, do you think ghosts exist? If you do, you’re not alone.

A 2017 study from a California university found that over 50% of Americans believe that a spirit of some sort could exist. Not only that, but a Pew Research study found that 18% of Americans believe they’ve seen a ghost.

We’ve all heard tons of ghost stories, but what does science have to say about ghosts? Unfortunately, there really isn’t any concrete scientific proof of ghosts existing, so why do so many of us believe in them?

Nearly every ghost sighting can be explained by science, or some sort of logic. One of the most interesting discoveries explains why some people think they feel the presence of ghosts.

It’s due to infrasounds. These are extremely low sounds that we humans are unable to hear, but fans, wind turbines and traffic can produce them.

Although we can’t hear these low sounds, we can feel them. These low frequencies can trigger distinct psychological effects, including things like discomfort, a sense of panic, and an overall sense of something being out of place.

Places where people have reported many ghost sightings also happened to have things that produced infrasound. Once people removed infrasound-causing objects, like fans, the ghost sightings suddenly stopped. Funny how that works, huh?

Another reason some people think ghosts exist has to do with electromagnetic fields. Researchers have found that electromagnetic fields may be able to influence an individual’s perceptions as well as their surroundings. In other words, it can make them hallucinate and see crazy things… like ghosts!

Speaking of seeing things, there are also reports of people thinking they saw visions of ghosts while they slept. This unfortunate case is known as sleep paralysis. This is when your mind wakes up before your body, causing you to have a paralyzed effect while you’re in bed. This also creates a waking dream effect, in which some people have reported seeing paranormal figures attempting to hurt them.

We might also believe ghosts are real, simply because we want to. If ghosts did exist, it would mean that the afterlife is real, which is a belief that comforts a lot of people today.

It’s pretty clear that ghosts don’t exist, at least according to science, but If ghosts were real, we’d never have to say goodbye to our loved ones. We could communicate with them, feel their presence, maybe even spend some quality time with them.

Let’s assume that every person who died on Earth became a ghost. Now that would be a pretty messy situation.

Generations of people would suddenly be wandering the Earth. So far, it’s estimated there have been over 100 billion people who have died on Earth.

Right now, the Earth has 7.5 billion people living on it. So if all those ghosts were living on Earth, it would start to get pretty crowded.

That is assuming that the spirits could interact with the world. Places around the world where wars have been fought could be particularly crowded as more people have died there.

And if we could see these ghosts, what might they be made of? Maybe they’d be made out of a material known as aerogel. It’s a synthetic substance that happens to be the lightest solid known to man.

If ghosts did exist, and were visible, you can bet they’d be made out of something like this. With massive groups of ghosts with physical properties everywhere – you might not be able to travel anywhere without running into one!

Sure, it might make the world a bit more exciting, but it’s probably better that ghosts don’t exist. Maybe after death, we go on to a parallel universe.
