Sister Sledge was right, we are family. It's well-known that all humans share a common ancestor but according to researchers almost all Europeans can trace that back to one guy. That guy is Charlemagne, the first Holy Roman Emperor. In 2013, scientists Peter Ralph and Graham Cooper published a study indicating that all Europeans are descendants from the same people, mainly from the ninth century. Sign up for our free Indy100 weekly newsletter Charlemagne, who lived during the 800s allegedly produced eighteen children with seven different women. By number standards, this means that people of European decent are most likely related to Charlemagne in some way. Celebrities like Bill Hader and Brooke Shields have revealed that they share the common ancestor. Even Sir Christopher Lee is a descendant of the Holy Roman Emperor. And if you're European, you probably are too. According to Scientific American, "because Charlemagne lived before the isopoint and has living descendants, everyone with European ancestry is directly descended from him." Some Europeans who take a DNA tests can see even their lineage directly traced back to the common ancestor. But before you jump at the chance to see for yourself, more than likely it won't pop up- even if you are a descendant of the Roman Emperor. This is because bloodlines have been diluted and not all genes are passed on from parent to child. So while you may be vaguely related to Charlemagne, you may not carry any of the same genes.

Scientists have figured out what the sun sound like - because yes, it makes a racket. By recording acoustical pressure waves in the sun, using an instrument called the Michelson Doppler Imager, solar physicists from Stanford University have determined the solar surface noise of the sun and it turns out it is pretty loud. If the sounds, which are apparently like 'screaming sirens' were able to pass through space, it would be 100 decibels by the time it reached us here on Earth, according to the American Academy of Audiology. This equals out to tens of thousands of watts of energy generated per metre on the sun, or 10x to the 100x the power of speakers at a rock concert.. Sign up to our free Indy100 weekly newsletter However, humans on Earth are unable to hear any of this because the sound waves emit at frequencies that are too low for the human ear to detect. The sun creates noise due to the constant flow of hot material on the surface and the sinking of cooled material towards the centre. Have your say in our news democracy.
