Science Facts
Did you know that the Sun is so massive that it contains 99.8% of the total mass of the solar system? That means that all the planets, moons, asteroids, comets, and other objects in the solar system only make up 0.2% of the total mass!
Did you know that the human body is made up of about 37 trillion cells, each with its own DNA? If you stretched out all the DNA in your body, it would reach from the Earth to the Sun and back 600 times!
Did you know that there are more stars in the observable universe than grains of sand on all the beaches on Earth? According to some estimates, there are about 10^22 stars, while there are only about 10^19 grains of sand.
Did you know that the longest living animal on Earth is a species of jellyfish called Turritopsis dohrnii, also known as the immortal jellyfish? This amazing creature can revert to its immature polyp stage after reaching adulthood, effectively restarting its life cycle indefinitely!
Did you know that the hottest place on Earth is not in the desert, but in a laboratory? Scientists at CERN, the European Organization for Nuclear Research, have created a plasma of quarks and gluons that reached a temperature of 5.5 trillion degrees Celsius, which is 250,000 times hotter than the core of the Sun!

History Facts
Did you know that the oldest known written language is Sumerian, which was used in ancient Mesopotamia (modern-day Iraq) more than 5,000 years ago? The Sumerians invented cuneiform, a system of writing that used wedge-shaped marks on clay tablets.
Did you know that the first recorded use of paper money was in China during the Tang dynasty (618-907 CE)? The paper bills were called "flying money" because they were so light and easy to carry around.
Did you know that the largest empire in history by land area was the Mongol Empire, which spanned across Asia and Europe in the 13th and 14th centuries? At its peak, it covered about 24 million square kilometers (9.3 million square miles), which is equivalent to 16% of the Earth's land surface!
Did you know that the shortest war in history was between Zanzibar and Britain in 1896? The conflict lasted for only 38 minutes, after which Zanzibar surrendered and became a British protectorate.

Did you know that a teaspoon of neutron star matter would weigh about 10 billion tons? Neutron stars are the remnants of massive stars that have collapsed under their gravity. They are so dense that a single cubic centimeter of their material has a mass of about 400 million tons!
Did you know that the loudest animal on Earth is not a lion or an elephant, but a shrimp? The pistol shrimp can snap its claw so fast that it creates a bubble of hot gas that bursts with a sound of up to 218 decibels, which is louder than a gunshot or a jet engine!
Did you know that the coldest place in the universe is not in outer space, but on Earth? Scientists at MIT have created a Bose-Einstein condensate, a state of matter where atoms behave like waves. They have cooled it down to less than one nanokelvin (one billionth of a degree above absolute zero), which is colder than any natural phenomenon known!
Did you know that the fastest animal on Earth is not a cheetah or a falcon, but a mite? The Paratarsotomus macropalpis mite can run at speeds of up to 322 km/h (200 mph), which is equivalent to a human running at 2,092 km/h (1,300 mph)!
Did you know that the most venomous animal on Earth is not a snake or a spider, but a snail? The cone snail has a harpoon-like tooth that can inject a potent neurotoxin that can paralyze or kill its prey. There is no known antidote for its venom, and some species can kill a human in minutes!
