Do Ghosts Really Exist?

Lots of people believe in ghosts — a spirit left behind after someone who was alive has died.

In a 2021 poll of 1,000 American adults, 41% said they believe in ghosts, and 20% said they had personally experienced them. If they’re right, that’s more than 50 million spirit encounters in the U.S. alone.

That includes the owner of a retail shop near my home who believes his place is haunted. When I asked what most convinced him of this, he sent me dozens of eerie security camera video clips. He also brought in ghost hunters who reinforced his suspicions.

Some of the videos show small orbs of light gliding around the room. In others, you can hear faint voices and loud bumping sounds when nobody’s there. Others show a book flying off a desk and products jumping off a shelf.

What’s the evidence?

Never before in history have people recorded so many ghost encounters, thanks in part to mobile phone cameras and microphones. It seems there would be great evidence by now. But scientists don’t have it.

Instead, there are lots of ambiguous recordings sabotaged by bad lighting and faulty equipment. But popular television shows on ghost hunting convince many viewers that blurry images and emotional reactions are proof enough.

As for all the devices ghost hunters use to capture sounds, electrical fields and infrared radiation — they may look scientific, but they’re not. Measurements are worthless without some knowledge of the thing you’re measuring.

When ghost hunters descend on an allegedly haunted location for a night of meandering and measurement, they usually find something they later deem paranormal. It may be a moving door (breeze?), a chill (gap in the floorboards?), a glow (light entering from outside?), electrical fluctuations (old wiring?), or bumps and faint voices (crew in other rooms?).

Well, centuries of physics research have found nothing like this exists, which is why physicists say ghosts can’t exist.

What is your opinion about Ghosts? Do they really exist?
