Have you ever argued with friends on who qualifies as the most beautiful woman in the world? Let’s be honest here, you probably have on one of those random drunken chats. While answers may have varied depending on people’s preferences, this question actually has a scientifically-proven answer. So who are the 10 most beautiful women in the world according to science, and how can it objectively quantify beauty?

Science has apparently found a way to objectively answer this question and save all that time we waste on personal preference by using a computerised mapping technique devised by London-based cosmetic surgeon Dr Julian de Silva. This technique is based on the Greek Golden Ratio of Beauty Phi, a formula known since ancient times which equals 1.618. That’s how the most beautiful women in the world have been identified and named. No need to argue with your friends anymore—just find another topic.

According to de Silva’s calculations, Bella Hadid comes in first with a 94.35 per cent perfect face. Just behind her is Beyoncé, who scored 92.44 per cent, just ahead of Amber Heard with 91.85 per cent. Ariana Grande, Taylor Swift, Kate Moss, Scarlett Johansson, Natalie Portman, Katy Perry and Cara Delevingne followed.

There you go, according to science, those are the ten most beautiful women on earth:

Today I have been featured in the @dailymail and @bazaaruk, declaring @BellaHadid the most beautiful woman in the world - according to the 'Golden Ratio' equation devised in Ancient Greece (and Beyoncé is a close second). The 23-year-old was found to be 94.35% 'accurate' to the Golden Ratio of Beauty Phi - which measure physical perfection. Her eyes, eyebrows, nose, lips, chin, jaw and facial shape were measured and came closest to the ancient Greeks' idea of perfection. Singer @Beyoncé, 38, was second with 92.44%, actress @AmberHeard, 33, was third with 91.85% and pop star @ArianaGrande, 26, was fourth with 91.81%. Kate Moss, 45, the highest rated Briton and in sixth place overall, had a reading of 91.05% - well ahead of her rival and the UK's other most successful supermodel, @CaraDelevingne, 27, who was in tenth place with 89.99%. The list was compiled using the latest computerised mapping techniques which allow us to solve some of the mysteries of what it is that makes someone physically beautiful and the technology is useful when planning patients' surgery. The Golden Ratio was a mathematical equation devised by the Greeks in an attempt to measure beauty. #news #beauty #plasticsurgery #harleystreet #beautifacation #beautifulfaces #jdsgoldenratio

The Golden Ratio of Beauty Phi 2/10 #jdsgoldenratio @beyonce - 92.44% Beyoncé came in second place as she scored highly on her forehead and brow area. She looks incredible as she approaches her 40s. She had a near perfect score for her face shape. How is the Golden Ratio of Beauty Phi measured? The Golden Ratio of Beauty Phi originates from the European Renaissance. Artists and Architects used an equation - known as the Golden Ratio - as an aid during the creation of their masterpieces. Scientists have since adapted the mathematical formula to explain what makes a person beautiful. The length and the width of someone's face is measured and then the results are divided. According to the Golden Ratio, the ideal result is roughly 1.6. Measurements are then taken from the forehead hairline to the spot between the eyes, from the spot between the eyes and the bottom of the nose and from the bottom of the nose to the bottom of the chin. A person is considered to be more beautiful if the numbers are equal. Attention is then given to the symmetry and proportion of the face. To be deemed 'beautiful' according to the Golden Ratio, the length of the ear must be equal to the length of the nose and the width of an eye should be equal to the distance between the eyes. #news#beauty#plasticsurgery#harleystreet#beautifacation#beautifulfaces#jdsgoldenratio

Now, as beautiful as these women are, it should be kept in mind that beauty doesn’t equal perfection and exact symmetry. While these 10 women all fall under the bracket of the Greek Golden Ratio of Beauty Phi, every woman is beautiful in her own way.
