INTERESTING FACTS ABOUT THE MOON

Moon

Think you know everything there is to know about the Moon? Think again! Here are interesting facts about the Moon. Some you might already know, and some will be totally new to you. Enjoy!

1. The Moon formed out of the Earth

Scientists now think that the Moon was formed when a Mars-sized object crashed into our planet about 4.5 billion years ago. The collision was so large that a huge spray of material was ejected into space. The orbiting ring of debris gathered itself into a sphere, and formed the Moon. How do we know that this is how the Moon probably formed? The Moon seems to be much less dense than the Earth and lacks a lot of iron in its core. Scientists think that the Moon is made up of the upper crust material, which has mostly lower density, than the composition of the Earth.

2. The Moon only shows one face to the Earth

Although the Moon used to rotate in the sky compared to our point of view, it has been slowing down billions of years. And at some point in the distant past it just stopped turning from our perspective. The Earth’s gravity holds the Moon in orbit, but it pulls differently at various parts of the Moon. Over a long period, gravity slowed down the Moon’s rotation so that it finally stopped, and always displayed one face to the Earth. A similar situation has happened with most of the large moons in the Solar System. In fact, in the case of Pluto and Charon, but objects are tidally locked to each other, so they present only one face to the other.

3. The Moon is slowly drifting away

Although the orbit of the Moon seems nice and stable, our only natural satellite is actually drifting away from us at a rate of 4 centimeters a year. This is happening because of the conservation of momentum in the orbit of the Earth. In about 50 billion years from now, the Moon will stop moving away from us. It will settle into a stable orbit, taking about 47 days to go around the Earth (it takes 27.3 days today). At that point, the Earth and the Moon will be tidally locked to each other. It will look like the Moon is always in the same spot in the sky. Of course, the Sun is expected to consume the Earth in about 5 billion years, so this event may not happen.

4. The Moon looks the same size as the Sun

This is an amazing coincidence. From our perspective here on Earth, but the Moon and the Sun look approximately the same size in the sky. Of course, the Sun is much much bigger than the Moon. The Sun happens to be 400 times larger than the Moon, but it’s also 400 times further away. This wasn’t always the case. Billions of years ago, the Moon was much closer than the Sun, and would have looked larger in the sky. And the Moon is moving away from us, so in the distant future, the Moon will look much smaller than the Sun.

5. The Moon causes most of the tides… but not all

You might know that the tides on Earth are caused by the gravitational pull of the Moon. But it’s not the only thing pulling at the Earth’s water, the Sun is helping out too. This is why we get very high and low tides from time to time. When the gravity of the Moon and the Sun line up, we get the biggest and smallest tides. Did you know that the Moon is also pulling at the crust of the Earth causing it to bulge up? You actually move a few meters every time the Moon is overhead, but you just don’t notice.

6. Gravity on the Moon is only 17% of the Earth

Want an easy way to lose some weight? Take a trip to the Moon and stand on its surface. Since the pull of gravity on the Moon is only 17% the pull of gravity on the Earth, you’ll feel much lighter. Just imagine, if you weighed 100 kg on the Earth, you would feel like you only weighed 17 kg on Earth. You would be able to jump 6 times further and carry objects 6 times as heavy. In fact, you had wings attached to your arms, you could even fly around inside a dome on the Moon under just your own muscle power.

7. The official name for the Moon is… the Moon

I know it’s kind of confusing, but the only real name for the Earth’s Moon is “the Moon”. When the Moon was given its name, astronomers didn’t know that there were moons orbiting other planets. And so they just called it the Moon. Now that we know there are other moons, it all comes down to the capitalization. The Earth’s moon is referred as “the Moon”, with a capital “M”. Other moons are given a lowercase “m” to show the difference.

8. The Moon is the 5th largest natural satellite in the Solar System

You might think that the Moon is the largest satellite in the Solar System. I mean look at it, it’s huge! But there are actually larger moons in the Solar System. The largest moon is Jupiter’s Ganymede (5,262 km), followed by Saturn’s Titan, Jupiter’s Callisto, Jupiter’s Io, and finally, the Earth’s Moon with a mean diameter of 3475 km.

9. Only 12 people have ever stepped onto the surface of the Moon

Only a tiny group of astronauts have ever set foot on the surface of the Moon. These were the astronauts on board the Apollo missions going from 1969 to 1972. The first person to ever walk on the Moon was Neil Armstrong. And the last person on the Moon was Gene Cernan, who followed his partner Jack Schmitt into the lunar lander on December 14, 1972.

10. And we’re going back to the Moon

NASA has been given the mission to return humans to the Moon, and set up a permanent research station. At the time of this writing, astronauts are expected to set foot on the surface of the Moon again in 2019.

WHY DOES THE SKIN ON THE EXTREMITIES WRINKLE AFTER A BATH?

skin

Okay, we all do this so I wanted to know why.

Despite its appearance, your skin isn’t shriveling after your bath. Actually, it’s expanding.

The skin on the fingers, palms, toes and soles wrinkles only after it is saturated with water (a prolonged stay underwater in the swimming pool will create the same effect, or washing the dishes) The stratum corneum — the thick, dead, horny layer of the skin that protects us from the environment and that makes the skin on our hands and feet tougher and thicker than that on our stomachs and faces — expands when it soaks up water. This expansion causes the wrinkling effect.

So why doesn’t the skin on other parts of the body also wrinkle when saturated? Actually, it does but there is more room for the moisture to be absorbed in these less densely packed area before it will show.

YECKY FACT ABOUT BIRD DROPPINGS

Sorry, no photo this time for obvious reasons but I thought this was an interesting fact about bird poo because I didn’t know this until now.

Ever wonder about that black dot in the middle of otherwise white bird droppings? I have because there are pigeons all over the place and I am always watering down the sideway to get rid of it.

So here’s the answer: the black dot is fecal matter. The white stuff is urine. The urine and fecal matter of bird droppings collect together and are voided simultaneously out of the same orifice. Feces tend to sit directly in the middle of droppings because the urine, slightly sticky in consistency, clings to them.

So beware of pigeon bombs, they are peeing and pooping on you at the same time. Gross!(No doubt this will be the one article that will get no views!) lol

WHY DO WHIPS MAKE A CRACKING SOUND WHEN SNAPPED?

whip

Why do whips make a cracking sound when snapped? I wanted to know the answer before testing the theory on someone butt.

The answer: Whips can attain the speed of more than seven hundred miles per hour when snapped, breaking the sound barrier. What you are hearing is a mini sonic boom when they snap. Guess it’s not okay to snap it against someone’s bottom.

WHAT ARE THOSE OCCASSIONAL TWITCHES AND JERKS WHEN FALLING ASLEEP

Babysleep

What are those twitches and jerks that occasionally wake us just as we are falling asleep? Dingy me wanted to know.

It has probably happened to you. You are nestled snugly under the covers, you aren’t quite sleep but you’re not quite awake. Just as your brain waves start to slow, and as you fantasize about having to see that hottie in your dream world, you are jolted awake by an unaccountable spasm, usually in a leg.

You are been a victim of what is called a “hypnic jerk”. Simply put: They occur when nerve fibers leading to the leg, in a bundle nearly as thick as a pencil, suddenly fire in unison. Each tiny nerve in the bundle produces a harsh tightening of a tiny portion of the muscle fiber that is linked to it down in the leg, and when they all fire together, the leg twitches as a whole.

Sleep experts haven’t pinned down what cases hypnic jerks or why they occur only at the onset of sleep. Although some people experience them more than others, their appearance is unpredictable unlike myoclonic jerks, spasms that occur at regular intervals during deep sleep.

WHY GOLFER’S YELL “FORE”

golfer

Why do golfers yell “fore” when warning of an errant golf shot? I’m nosey, I wanted to find out.

The answer is: This expression, popularized by former President Gerald Ford, actually started as an English military term. When the troops were firing in lines, the command “‘ware before” indicated that it might be prudent for the front line to kneel so that the second line wouldn’t blow off their heads. Smart move, huh?

“Fore” is simply a shortened version of the “before” in “‘ware before.”

WHY DON’T WE GET GOOSEBUMPS ON OUR FACE?

goosebumps

Why don’t we get goosebumps on our faces?

Silly question, right? Well that’s me, I am silly enough to want to know the answer.

And the answer is we get goosebumps only on parts of our bodies that have hair. The purpose of body hair is to protect us from the cold. But when our hair doesn’t provide enough insulation, the small muscles at the bottom of each hair tighten so the hair stands up.

Animals are covered with fur, the risen strands form a protective nest of hairs. Cold air gets trapped in the hair instead of bouncing against the delicate skin, thus the hair insulates the animals against the cold.

Although evolution has caused humans to lose most of their body hair, the same muscular contractions occur to defend against the cold. Instead of a mat of hair, all we have to face the elements are a few wispy tufts and a multitude of mounds of skin, which used to support an erect hair and now must go it alone. When a male lion gets “goosebumps” his erect hair makes him look ferocious. Our “goosebumps” only serve to make us look vulnerable.

DID YOU SEE THESE SCENES IN MOVIES?

1. In Star Wars, released in 1977, just before Luke and Princess Leia swing across the Death Star’s chasm, a stormtrooper falls in.

2. In the Empire Strikes back, released in 1980, in the battle on the ice planet Hoth, a rebel soldier screams when his satellite dish laser gun is struck by laser fire and explodes. In that same movie, as Han Solo is being frozen in carbonite, Chewbacca knocks a stormtrooper off of the platform.

3. In Constantine, the scene where he is going to go between realms using a cat as a go-between. First the cat is facing Constantine, next scene the cat is facing the door and in the following scene, it’s facing Constantine again.

4. In the movie Commando, when going to save Sully, the yellow Porsche is dented on the driver’s side. One scene later, the damage is gone.

5. In the Terminator: Rise of the Machines, they board a airplane with the numbers N3035C. The next shot of the plane, the numbers are changed to N3973F.

6. In American Pie, a young lady is drinking from a blue plastic cup. A scene later, while still at the restaurant, the cup is see clear.

7. In the Pirates of the Caribbean, The Curse of the Black Pearl, just as Jack says, “On deck, you scabrous dogs,” to the very left edge of the screen over Jack’s shoulder is a grip crew member with a tan cowboy hat, white short sleeve tee shirt and sunglasses, just standing there looking out to sea.

8. In Spiderman, when Peter Parker shoots his web at the bedroom lamp and pulls it across the room, it smashes against the wall and breaks. But when Aunt May is talking to Peter from the door seconds later, the lamp is back on the dresser in one piece.

9. In Harry Potter and the Order of the Pheonix, there are two scenes during which Harry is shown having visions of the Dept of Mysteries while he is asleep. The first scene happens after Harry’s confrontation with Seamus in the Gryffindor common room. There are shots of Harry lying in bed wearing a short sleeve, crew neck tee shirt, but when he is startled awake by the vision of Voldemort, he sits up wearing a buttoned t-shirt. The next day is the first day of DADA class with Umbridge. That last shot of Harry in the t-shirt was cut from a later scene. Later in the film, when Harry has the vision of Arthur Weasley’s attack, he is wearing the t-shirt.

10. In Twilight, Eclipse, in the last scene where Edward and Bella are sitting in the sunny field, Edward is not sparkling. Oopsie!

11. In X-men 2, in the end, when the President is visited by the X-Men, he receives a blue binder, which is laid in front of him on the table. When they have left, you see a shot including the President’s desk, and you can see that the only thing he has on the table are some sheets of paper, stapled in the upper left corner, opened up. Then the shot changes to a close-up of the President, and then back again, and you see the blue binder in front of him, closed, and the papers have disappeared.

12. In the Dark Knight Rises, when Catwoman shoots one of the tumblers we see it get hit and explode from behind, then 2 shots later we see her pass from the front. Also after the tumbler gets blown up the next wide shot from above reveals the tumbler is still there.

13. In The Lord of the Rings: The Fellowship of the Ring, when the Fellowship meets in Rivendell, and Gimli tries to break the Ring with his axe, the axe breaks into many pieces on the platform upon which the Ring is laid. At first, the pieces are there in the close-up view. When the camera pans back for a long range view of the Fellowship, the pieces of the axe on the platform are gone. In the following close-up, the pieces magically reappear.

14. Also in The Lord of the Rings, as the cave Troll throws Pippin from its back, he is holding his sword in his right hand. When he hits the ground it is in his left.
