People Share The Best Facts About Space That They Know
Space is the great mind-bender. Just think about it on a deep, meaningful level for more than five seconds and try not to freak out at the size and scope of it. While we'll discover plenty in our lifetimes, the sad truth is space is way too large for all the secrets to be discovered before we pass on. Fortunately, there's plenty of cool facts out there now to keep us occupied until those days come.
Reddit user, u/macmite, wanted to know the coolest about the final frontier when they asked:
What's your favorite space fact?
Two Words: Ice. Volcanoes.homer simpson wow GIFGiphy
Saturn's tiny moon Enceladus has volcanoes that spew ice particles at speeds faster than the escape velocity. The particles leave Enceladus' atmosphere and get pulled into Saturn's ring system forming the E ring!
Always Moving Away From Each Other
Even though the speed of light is the universal speed limit, many clusters of galaxies are moving away from each other much faster than the speed of light.
The simple version of how this can happen is because of frame of reference. You can look at it like the space in between is expanding while the galaxies are standing still. This is a huge rabbit hole, but pretty dam cool.
Who Loves A Math Fact?
There's an exoplanet which is mostly made of diamond. Just a small portion of it would crash the diamond's value, if brought here.
It's called 55 Cancri e. It's worth $26.9 nonillion. That's 7.27*1017 times the money on Earth (in circulation)
One Or Two Scoops?
One table spoon of a neutron star weighs 900 billion kg. (More than Mount Everest)
The fastest thing we might have ever launched into space from Earth, and months before Sputnik, was a glorified manhole cover. By accident.
I say might because nobody knows for sure if it actually reached space or disintegrated on the way up.
But We Shouldn't...Right?
You could fit all the planets in the solar system in the space between Earth and the Moon.
Neptune was discovered using math. A man named Alexis Bouvard made some predictions on Uranus's future position using Newton's laws of gravity, but when it was later observed it was found to be slightly off. Urbain Le Verrier found that if he assumed there was another planet further out, the discrepancy would be explained and used math to predict where it could be found. Finally, a man named Johann Galle looked in the spot Le Verrier specified, and lo and behold, there was Neptune.
What A Stroke Of Luck
Being able to see a total solar eclipse is a sheer coincidence of timing. The moon is just large enough and just far enough away from Earth to appear to be the exact size of the sun during a total eclipse (when it covers the entire disc of the sun). Since the moon is slowly moving away from Earth, one day it will no longer appear large enough to fully cover the sun and there will be no more total eclipses. This won't happen for 600 million years though, so don't panic.
Backwards Is Forwards
Venus spins backward.
Whatever the direction of the other planets when they are rotating, Venus rotates the exact opposite way.
Everything Is Always Movinglisa simpson space GIFGiphy
If you were to scale the universe down so that the sun was the size of the period at the end of this sentence, the nearest star would be 4 miles away.
The Big Bang was not an explosion of matter, rather it was an expansion of space itself. Everything is getting farther away from everything else, as all space is expanding. There is no center of the universe.
A Collapsing Universal Structure
Because a black hole has no depth this means the 3 dimensional material placed within it is stored in a 2 dimensional area. It's recoverability notwithstanding, this is the foundation of the idea that the 3d world we know is a simulation and our world actually exists in a lower dimension like how a hologram presents a 3d picture, but is actually a 2d plane.
The Lack Of Gravity
In space, your body starts to change because of the lack of gravity. You grow taller, your vision can change because basically your eyeballs change shape. Even your blood circulation is changed by no longer being effected by gravity.
There are more trees on earth than there are stars in the Milky Way galaxy!
According to the estimates from the study (2015) conducted by a team of scientists from Yale University, there are about 3 trillion trees covering our planet where as the number of stars in the Milky way is estimated (mathematical calculations ofc) to be between 100-400 billion.
This is somewhat bittersweet cuz, the team estimates we are removing about 15 billion a year, with perhaps only five billion being planted back.
So mind-blowing and sad at the same time.
Hey! Want To Feel Small?
There are stars out there so huge, that if you replaced our sun with one of them in our solar system it would swallow everything up past the orbit of Mars. And that's not even the biggest thing out there. Remember that actual photo of a black hole that was taken last year? The dark part in the middle, the event horizon, is more than three times the size of the orbit of Pluto.
Think About It: Where Else Would They Go To The Bathroom?
That there is a bag of poop on the moon.
Be Jealous Of Our Descendants
most of the visible stars in the night sky are binary stars, two stars orbiting each other
Sometimes I get envious of our future descendants who will get to set foot on a planet in a multi star system. They'll get to see many sunsets...or no sunsets.
Space welding. In a vacuum, you don't need welding materials to get two metals to fuse - they will do it on their own if you place them close enough
But they need to be the same material, and the surface needs to be free of oxidation.
Imagine having two blocks of pure aluminum or iron in a vacuum. If you touch them together they'll get stuck, and fuse, like a weld. Why? Because the atoms each block is made out of don't know which block they belong to. On Earth this doesn't happen due to oxygen in the atmosphere. If you scrub off the surface layer of a piece of metal the new surface comes into contact with oxygen, and oxidizes pretty much instantly.
Nope, Too Big. *leaves
That there are 100 billion galaxies in the observable universe, and that number is likely to at least double as Hubble goes further and observes more of the universe.
It's insane to think that we live on a mere speck within the Milky Way galaxy, and that there are possibly 199,999,999,999 other galaxies out there, each separated by millions of light years. The enormity of the universe is mind-boggling.
We'll Never Get Anywhere Soon, Will We?homer simpson space GIFGiphy
After traveling since 1977, Voyager 1 has now reached about 20 Light-HOURS distance from the Sun. Vast does not begin to describe the Universe
Voyager 1 travels at 38,000 mph or about 17 kilometers per second. It has taken 43 years to travel from earth to where it is now, 21.2 billion kilometers away.
Speed of light is about 1.07 billion kilometers per hour.
Voyager 1 would then be approximately 22.1 billion kilometers from the sun. 20.65 light hours away.
That's insane! 17 kilometers per second and it is a tiny fraction of the speed of light.

One would think we're in a place in time where all conversations should be easy.
But that is not the case.
So much is still too "taboo" to be truthful about.
It is so frustrating.
There is so much to discuss.
Being shy is understandable, but it's something that we can all get over.
Redditor No_One_Special34 wanted to breakdown some barriers with a few simple conversations, so they asked:
"What is a taboo subject that should be talked about more?"
"Child/infant death. When my daughter died a bunch of people just... stopped talking to me altogether."
"I'm sorry to hear about your child."
"A 7-year-old was hit by a truck last week near my son's kg. I've never met the boy but I have had nightmares about it. I can't imagine what the parents are going thru right now. I can't imagine what you are going through."
"This happened to my mom when my brother died. Nobody knew what to say so few people said anything, and then it was treated like it didn’t happen."
The Aging Process
"We are a disgustingly ageist society. No wonder people pay BILLIONS for plastic surgery, hair color, and fitness, etc to stay relevant and not be thought of as useless or 'other.' It’s so very hateful. I think our society fears old age and death. It’s a f**king pathos."
"THANK YOU! I'm a 20-year paramedic. One of the things that I really hoped COVID would shed a light on is the absolutely abhorrent treatment of our elderly and infirmed. The 'treatment' in far too many nursing homes is negligent to a criminal level."
"Household budgets and finance - how much your parents make, how much is the mortgage, car insurance, car payment, and so on."
"That's easy. House, two cars, three kids, stay-at-home wife, pets, college tuition for everyone in the bank, a summer cottage home by the lake, and a hobby like golf should all do if you're a hardworking drug dealer nowadays."
"Agreed! We have gone into detail about our finances with our kids. We have them pick jobs on LinkedIn and a home on Zillow and budget so expenses and have them watch as they realize they can't afford expensive stuff on a crap salary. It's been really great."
Look for the Signs...
"Many people tend to assume that abusive people look creepy/scary and behave badly in general, but they don't seem to get that anyone can be abusive, regardless of appearance or demeanor. An abusive person can easily be charming, attractive, funny, witty, etc."
"Just because you think someone has a few positive qualities does not mean they're incapable of abuse."
"If someone's child 'seems' happy and well behaved, it does not mean that they are automatically OK or safe. There are many signs of abuse, and I wish that more people educated themselves on this issue. We can literally save lives by doing so."
The Girl Truth
"Girls need to know everything there is to know about menstruation before they experience it. At my school we were only given a quick 'every month you will bleed out your vagina, you can use pads or tampons to absorb it.' Nothing about any of the other mental or physical effects, nothing about how to deal with them, and nothing else reassuring."
Why are girls not taught more sooner?
Like what year are we living in?
"Number one for me, especially out-of-order deaths (young deaths). My husband died when I was 33 and he was 38. It's been almost 3 years and people still struggle with how to talk to me. We need to talk about death more as a society."
Only Legal One
"Alcoholism, especially in older generations."
"The biggest drug in the world, the most dangerous, only legal one. Alcohol has been disguised to make society believe it isn't even a drug. Now we're all hooked and can't go a week without a drink, funny because the cravings come back within a week."
"I quit drinking 18 months ago and it kinda sucks because if you want to go meet new ppl or go on a date it usually involves alcohol."
"Comprehensive sex ed. My mother never had sex ed and was convinced that vaginal discharge wasn't normal and that your crotch didn't sweat."
"My mother had a condition that requires her to use a catheter. She was shocked to learn that she doesn't urinate from her vagina, and that the opening to her urethra is actually slightly above it. She's 75. I'm a dude, and I've known that since I was 14."
"She was raised Catholic, and her mother taught her nothing. Not even what her period was. She was convinced she was dying."
Follow the Money
"Financial debt. In my line of work, I see people's bank accounts and credit reports every day and it is very rare that someone has zero debt. Excluding mortgages (which is a given) the vast majority have car finance, personal loans, and credit card balances. Mostly it's manageable, credit is mostly a convenience for which a person pays interest."
"But debt can also destroy a person. It can keep you up at night feeling like you're literally suffocating. It can lead to suicide. I know because I was close at one point. I don't know if I would have actually gone through with it but I had planned it to the point of measuring rope from the timbers in my attic to my neck and to ensure my feet wouldn't touch the ground."
"If you are in debt you are not alone, you're in the majority. If it's a struggle, notify the lenders/creditors; they're legally obligated to offer options to help you. It might reduce your credit score a bit but please don't ever reduce your life instead."
"Life is precious and money isn't. If you're struggling financially please speak to someone. There is no shame in it, pretty much everyone is struggling financially so someone will understand but please don't let a credit card balance be the reason your life ends."
"Pooping and poop problems. Colon cancer is so common and relatively treatable, but like all cancers, it's so much better to catch it early - yet so many people are too embarrassed to talk about poop problems, and they don't bring it up with their doctor until it's too late."
"I have ulcerative colitis and make sure all my friends know I'm totally comfortable talking about poop if they ever have any questions about whether something happening to them is normal or concerning."
Speak more. Speak louder. We've all been quiet too long.
The Thing People Would Look For First If Given A Box Of Everything They Ever Lost
As much as we might try to take care of our things, there are going to be instances where we lose things that we love.
Ironically, those lost things might be some of the most meaningful things we have in our lives.
Redditor baba_yaga_777 asked:
"If someone offered you a box of everything you ever lost, what would you look for first?"
A Mother's Brooch
"The brooch I bought for my mom's birthday when I was five years old (60 years ago)."
"I took all my money out of my bank and walked to the local Hallmark store. The nice lady took my money (probably less than $2) and wrapped up the gift."
"When my mom opened her gift, we walked back to the store 'to thank the lady for wrapping it so nicely.' It was actually so my mom could offer to pay the rest of the cost of that beautiful brooch. The lady wouldn't accept any more money, though."
"And here we are, 60 years later, and I still remember the incredible kindness of that lady."
"I don't have the brooch or my mom, but I do have this memory."
"When we left Yemen during the civil war in 1994, it was rushed and we lost a handbag that had all family photos from 15 to 20 years prior. It sucks not to have pictures of me when I was younger."
The Perfect Fit
"My swim trunks for this summer. I just got them last year and they fit me perfectly, and now I can't find them for the life of me. It p**ses me off thinking about it."
All Progress Saved
"The 'Pokémon Crystal' game that I had leveled all of my favorite characters up to Level 80. The housecleaner swiped it and my parents wouldn’t believe me. F**k you, Julie."
Lost Loved Ones
"My daughter. She was gone way too quick."
A Beloved Baby Blanket
"My childhood blankie. I have no idea what happened to it!"
"I somehow managed not to lose or destroy mine and gave it to my firstborn child. He still keeps it in his bed and turns seven soon. I think I’d ask for that too if it was lost."
Former Best Friends
"My best friend from my formative years."
"Oof, same. She was like a sister to me. She lives on the other side of the country now and, even though we grew apart, I miss how I felt when I spent time with her."
"The stuffed platypus I had when I was in elementary. Every time my mom mentions finding stuff in my grandpa's house, I ask about it."
In Exchange for Toxic Relationships
"The self-esteem that I allowed others to destroy during a phase of illness."
"High school sketchbook full of emo edgy drawings."
The Family Ring
"My mum's ring she'd been given by her Grandma that I pawned (my mum agreed at the time but always regretted it afterwards)."
"I got way, way less than its worth, since the guy took advantage of my age and desperation. The worst thing is, I can't even remember the design so can't ever have it replicated and can't ask my mum because she passed away earlier this year."
"Sure, I still love holidays but… as a kid, it was like, 'Holy mother of everliving f**k, Halloween is in THREE WEEKS? That is entirely too long. I will never be able to wait. Holy d**n.' And when it finally arrived, I'd have the night of my life."
"Now it’s like, 'Oh no. Halloween is in two days. Uh... Oh well...'"
The Sea of Lost Picks
"As a guitarist, all of my f**king picks."
Junk Drawers and Boxes
"The box I lost that had everything in it."
Quite the Conundrum
"The issue is that I can't recall what I've lost."
We've all lost things in our lives, some more important than others.
It's especially telling that at least most of us know exactly what we would seek first, before anything else that might possibly be in that box.
People Share What Their Reaction Would Be To Meeting A Naked Hiker On The Trail
There are several things that are appealing to hikers.
Being out in nature and taking in some fresh air is a huge motivation for people to get out of the house.
Getting exercise is also a factor to maintain a healthy heart.
But there could be one unexpected element to a hike that can happen hypothetically, and it's sure to raise your heartbeat.
Specifically, seeing something shocking along the hiking trail, like, say, a naked person could make for an exciting–or disturbing–hiking outing. It certainly doesn't get any more au natural than that.
Curious to hear from strangers, Redditor spenf asked:
"What would be your reaction if you encountered a nude hiker?"
These Redditors assessed the situation and saw no harm.
"I have passed two nude hikers in my 35 years of hiking. One male, one female, years and thousands of miles apart. Both said 'hello'. I said 'hello.' One mentioned the trail was washed out ahead but a second trail has been cut. I thanked them for the heads-up. Some people like the wind and sun on their skin. Both had on hiking boots. To each their own."
Sign Of Good Character
"I have. Three times! I'm an avid backpacker and you can usually find me in Yosemite, SeKi, Emigrant or Carson-Iceberg in California on any random summer weekend."
"My standard line: 'Afternoon, I didn't realize it was so cold out today!'"
"One of them didn't get the joke. The other two laughed their nude a**es off."
"Here's my reasoning. If you're naked and can laugh at a joke, you're probably not a threat."
"Depends. A hiker with hiking boots/shoes and a backpack, but otherwise nude, or a completely nude person on a hiking trail?"
"Scenario 1: I give a friendly wave and hike on."
"Scenario 2: I give a more tentative wave and hike on, maintaining a heightened awareness of my surroundings."
"I met one once. A middle aged man in ok shape. Had nice hiking boots, thick wool socks, fancy framed backpack, two walking poles, hat, sunglasses, and nothing else on."
"I said hi in a neutral voice, he replied hi in an equally neutral voice. We passed, I did not look back."
Some hikers are suspect.
"While backpacking out of Rocky Mountain National Park we encountered a dude wearing nothing but shoes and some very small shorts. He was off trail about 100' at the edge of a meadow, walking and swinging a machete. I...did not approach. He was probably a mile in from the trail head. I'm guessing drugs."
Beware Of Black Magic
"Ha! There are a lot of superstitious rumors/stories circulating around scenario 2 in India. Apparently, people who practice black magic with the sole intent of harming someone are often seen walking naked in places you don't expect people, carrying weird items."
"Either you interrupt them by disturbing them (no clue what happens next) or you run in the opposite direction."
You may want to take note.
"I live in the Bay Area and naked hikers are not uncommon."
"Good naked hiker: has appropriate shoes, a backpack or fanny pack, is hiking with intention and looks tanned and fit and like he does this regularly. Good naked hikers will give you room so you don't have to interact unless you really want to."
"Bad naked hiker: shoeless, visible sores, scrapes, or burns, moving erratically (i.e. really slow or in a zig-zag). Might be a drugged out person. Out-of-shape or pale are indications this is not normal for them and they may not have intended for this to happen."
"Exhibitionist: makes a point to make eye contact, smile at you, wave, try to involve you. Good naked hikers are usually on long, deep trails where they're less likely to encounter others, and they tend to give clothed hikers a wide breath out of a sense of respect and consent. Exhibitionists get chummy; it excites them to be seen naked."
"Also depends on the area. A deep woods area with long trails is ideal for naked hiking. Shorter and more accessible trails are less okay because there's a higher likelihood of encountering families with children."
"Also depends on if they're with friends or not. A group of naked hikers is less concerning than an individual."
"All this boils down to:"
"If you see a naked hiker, mind your own business. A good naked hiker isn't trying to bother you. A bad naked hiker is potentially dangerous. An exhibitionist wants attention so any attention paid to them will fuel them. Best thing to do is nod as you pass and carry on like you haven't even noticed."
"Edit: There are actually areas in the Bay Area where it's permitted to hike naked. Regionally, some places allow nudity. Also some places allow women to be topless so a topless female hiker might just be evening out her tan. It's best not to assume and to know the local laws before passing judgement on a person getting their nature on."
Guilty as charged.
The Name Is A Dead Giveaway
"No reaction at all, since I would be nude myself."
"Stare in disbelief. That's just very strange and coincidental for two nude hikers to run into each other."
"I guess make sure they have sunscreen also."
To each their own, but if hiking in the nude is your thing, you do you.
And just a heads up: If you're walking around in the buff and happen to be wielding a machete, you're going to make people very jittery. So maybe drop the prop.
Also, wear plenty of sunscreen.
The Absolute Hardest Parts Of Dating After Age 30
30 is the new 20.
At least, that's what a lot of people tell themselves after they pass that milestone birthday.
Even so, while age is merely a number, people still find certain things grow increasingly more challenging with each passing year.
Including, or even particularly, dating.
Those still on the hunt for love after turning 30 might grow increasingly insecure, worry that their moment has passed, or be unable to ignore the ticking of their biological clock reminding them that time might be running out to start a family.
Not to mention, playing a losing game over and over can become completely and utterly exhausting after a while.
