Faced with these, intelligent people take their time but are much more likely to get the answer right. The findings […]
The Whole Universe Might Be Doomed To Evaporate
Black holes are not eternal. Extremely slowly, they lose mass and energy in the form of thermal radiation – heat. This is known as Hawking radiation, and over incredible time frames would lead to black holes evaporating, eventually disappearing. A new theoretical paper suggests that this is true for more than just black holes: that […]

The Medieval World’s Most Terrifying Weapon Is Still A Mystery Today

What Happens If You Fry In Microgravity? ESA Has An Answer
What would it be like to fry in microgravity? Throwing potatoes into boiling oil while floating around in space sounds like a recipe for chaos and third degree burns. Scientists are not interested in that, luckily, but in how cooking with oil might need gravity to be effective. And it turns out that this is […]

Ions inside the spherical Tokamak ST40 soared to over 100 million degrees Celsius, breaking the record for this kind of reactor. One hundred million degrees Celsius (around 180 million degrees […]
“The Great Stink” Engulfed London In A Cloud Of Fetid Air Back In 1858
In 1858 a catastrophic pollution event descended upon London as its sewer-filled streets and waterways built up to create “The Great Stink”. The Thames was and remains a central feature of England’s capital, but back then it wasn’t filled with seals, seahorses, and eels, like it is today. Back then, it was basically a big […]
