Cows don’t have upper front teeth. They do have molars on top, in the back of their mouths, but where you’d expect upper incisors, cows, sheep, and goats have a thick layer of tissue called a dental pad. They use that with their bottom teeth to pull out grass.
100 Mind-Blowing Pull Facts
Cars can easily reach 140 degrees Fahrenheit. You might be driving along the highway and not notice how hot your car is getting. But when you pull over for a while, your car can reach intense degrees.
The place where cartoon characters store things, just to pull out of thin air, is known as “Hammerspace”. If you’ve ever seen Tom & Jerry, you’d be familiar with those scenes where Jerry would pull a bat out of nowhere to bonk Tom mid-chase. However, animators have given this unseen, mysterious sphere where characters pull objects out of a name: the Hammerspace.
You can become less depressed if you stay up. Research has found that there is a correlation between those who pull all-nighters and those hazing out of depression. This is because the longer you go without sleep, the more active your brain becomes. However, it is not recommended to go without sleep as it is a necessary need for humans to be able to function normally.
When the moon is directly overhead, you weigh slightly less. The Moon’s gravitational force acting directly above an object reduces the Earth’s gravitational force – less gravitational pull on you means less weight.
The longest time without sleep is 11 days. The longest time recorded of a person without sleep is approximately 264 hours. Within 3 to 4 days without sleep, you may start having hallucinations. Sleep is a biological function for a reason – it is not advisable to pull all-nighters all the time.
Left-handed people often have their unique style of handwriting because they have to push the pen across the paper rather than pull it as right-handers do.
Mars has 2 moons called Deimos and Phobos. They are named after the two horses that pull the Roman God of war, Mars’, chariot. They may be asteroids captured by Mars’ gravity.
The Moon is getting farther away every year. The Moon exerts a pull on Earth, causing our planet to be slightly egg-shaped. It affects water even more, creating tides and causing the oceans to pile up towards one side of the planet, forming a ‘tidal bulge’. This bulge is dragged around with the Moon as it orbits. As Earth rotates faster than the Moon – 24 hours versus 27.3 days – the bulge moves slightly ahead of the Moon’s position in orbit. The Moon pulls back on it, effectively trying to slow it down and causing Earth’s rotation rate to gradually slow down over time as a result. As the two bodies interact through gravity, this tugging causes Earth to lose energy while the Moon gains energy. Because of this energy boost the Moon is slowly spiralling outwards, moving away from us by 3.8cm per year.
Black holes give off light. Venture beyond the event horizon and you’ll not be able to escape the powerful gravity of a black hole. Black holes are objects so dense that not even light can escape their gravitational pull. Yet despite this, black holes can shine brightly, and this may be one of the most contradictory-sounding facts about space on our list. Supermassive black holes can illuminate the centre of galaxies and are known as active galactic nuclei. How can this be? As cosmic material falls into a black hole, it forms an accretion disc that swirls around it. This material gets very hot and glows: it can even power jets of material that shoot out of the black hole into space. This all occurs just outside the event horizon and is one of the ways astronomers can detect black holes even though they can observe them directly.
In many cultures, Reindeer are used to pull sledges and sleighs. There’s evidence of this dating back 7,000 years ago in Siberia!
Earth isn’t round. While this sounds like an elaborate joke, we’re serious. Earth isn’t flat, but it’s not perfectly round either. Earth’s rotation causes the planet to bulge at the equator and flatten at the poles, while the distribution of mass on Earth (which is not perfectly uniform) causes small variations in the gravitational pull at different locations on the planet. These variations are too small to be seen in pictures of Earth from space, so they appear round to the human eye. The shape seen in the video above is not technically the shape of the planet, but its ‘geoid’, the shape of its mean sea-level surface extending around the entire globe. The map was produced using data collected from ESA’s Gravity and Steady-State Ocean Circulation Explorer (GOCE) and shows the most detailed map ever created of Earth’s gravity field.
The Moon is drifting away from Earth. You read that correctly! The Moon is gradually drifting away from Earth at a rate of approximately 4 cm per year. This phenomenon is caused by the Moon pulling on Earth’s oceans creating tidal forces that produce a bulge of water on the side of Earth facing the Moon. This bulge in turn creates a gravitational pull on the Moon, causing it to accelerate slightly and move further away from Earth. Over time, this process has caused the Moon to move farther away from Earth each year. This gradual drift is not noticeable on a day-to-day basis, but over millions of years, it can have significant effects on Earth’s rotation. Today, most scientists believe the Moon is ‘Earth’s child’ – a large body collided with Earth, destroying our planet’s mantle and sending material into orbit from which the Moon formed. This ‘big splash’ theory would explain why the Moon’s rocks are similar to those on Earth. Bonus fun fact: Australia is wider than the Moon. The Moon sits at 3400 km in diameter, while Australia’s diameter from east to west is almost 4000 km. The Moon, as a sphere, has more surface area, but it’s still pretty impressive.
