Have you ever seen a stranger whose face is similar to someone we know? Or see other people who turn out to be very similar to you? If so, maybe it's called a doppelganger.

Some people claim to have seen their own "twin" aka doppelganger or someone else's, whether in real life when they cross paths somewhere, or on social media when they accidentally scroll the timeline. To the extent that there are those who believe that every human being on this earth must have a twin who lives in another part of the world.

Regardless of whether it's true or not, what's clear is that many photos circulating on the internet prove that some people are very similar to other people, some even have their "twin" who lived long before they were born, aka different generations! Not only ordinary people, many artists also have doppelgangers.

If you want to see how the portrait looks like, check it out here. For those of you who are still curious about doppelganger, check out the review below. To the extent that there is evidence using scientific research.

# What is a doppelganger?

Doppelganger comes from German; Doppel which means double, and Ganger which means walker or goar. When viewed from the term, doppelganger is a shadow that resembles the self and accompanies every human being on earth.

The point is that the doppelganger is actually not real or just a 'shadow'. There are also some who associate the same myth and bad feeling, whoever sees his doppelganger, then the day after that he will die. Of course this is just a myth.

# Facts about doppelgangers

Teghan Lucas and a number of researchers at the University of Adelaide, have sought to find out more about this doppelganger. Their goal is to find out about the risk of being wrongly accused of the murderer. Some of us may be interested if we know that we have a "twin". But the news is definitely not good news for the police and law enforcement because it can increase the risk of wrongful arrests.

So, for this reason, Teghan analyzed the faces of nearly 4,000 people using a collection of photos of members of the American military, complete with measuring the distance between the eyes, ear size, and so on.

And the results of the analysis say that 1 in 135 people on this earth has a doppelganger. In essence, it is very possible for people to have "twins", although the chances are very small.

# Twins are similar in human eyes

So, like this, 1:35 above is obtained from the results of a very detailed analysis, so that the distance between the five senses is also measured. If that's the case, it's really hard to find one that's similar to each other, because if for example your ear length is 60mm and your doppelganger is 59mm, you're not categorized as similar in that study.

It's a different story if we only rely on the visual eye to judge the resemblance of a person to another person. It could be that the possibility of us having a "twin" is much greater.

But what is perhaps no less unique is the enthusiasm some people feel when they find out that he actually has a doppelganger. Yes, some people even feel proud when they know that he looks like someone else, especially if the doppelganger is an artist, celebrity, or famous figure.

Statistician Nick Fieller, argues that people tend to feel close to other people who have something in common with themselves, including faces.
