- #WhatIf We #Built #Cloud #Cities on #Venus?



The #Earth might not be here #forever. A huge #solar #flare, an #asteroid #impact, or a #local #gamma-ray #burst - anything could wipe us out for #good. If we're looking for someplace to #escape to, there is one #planet in our #SolarSystem that is somewhat #similar to Earth, though we don't know much about it. It might even be #hosting some #microbial #life. No, it's not #Mars - it's #Venus.

- #WhatIf There Was No #Salt in the #World?



- #Cities have been #named after it, #economies have been #built on it, #wars have been fought over it, your #life depends on it. Salt may be the most #important, and the most #divisive, #mineral in #history. What is it worth to us #today? There are more than 14,000 #uses for salt, but to most of us, it only means one thing: high #blood #pressure.

- #WhatIf You #Fell out of an #Airplane at 30,000 #Feet?



30,000 feet, 9,144 #meters, 9 #kilometers or 5.7 #miles - so far, only one #person has ever #survived a #free fall from that #height. Would you be as #lucky? On #January 26, #1972, an #explosion aboard J.A.T. #airways #flight #367 resulted in the #impossible. 22-year-old flight #attendant #VesnaVulovic, fell from 10,000 meters (33,000 feet) in the #air, setting a #world #record for #surviving the highest fall without a #parachute. How did she #survive?

- #WhatIf You Fell Into a #Pool Filled #Snake #Venom?



Did you know that a #single snake #bite can #kill an #adult #elephant in just a few #hours? And if you're not #careful, snake venom can kill you in only 15 #minutes. But that's from a #venomous bite. What if the venom was already #collected and you took a #swim in a pool #full of the #stuff?
What would #swimming in venom be like? How would snake venom #affect your #body? And could this actually be #good for you?

- #WhatIf #Aliens Are #Watching Us?





Do you ever feel like you're being watched? Not by a creepy stalker, but by aliens. Yup, it might be happening.

- #WhatIf You Fell Into a #Pool Full of #Sharks?



Sharks are the #oceans' #primary #predators. #Eating every #fish in their path. But what if you ended up in a #pool full of them, and you were the prey? What would happen when they smelled your #blood? What are your chances of #surviving? And how #dangerous are these sharks?

- #WhatIf You #Eat #Mold?



You've seen it #growing on your #fruit, #eating your #leftovers, and maybe even #hiding in your #basement. Mold smells #bad, it's #creepy-looking, and even if you don't know much about it, you probably know enough to keep it as far away from your #mouth as #possible. But what would happen if you ate some without #realizing it? What would it do to your #body? Would you have to go to the #hospital? Is there any #situation where it could actually #taste #good?

- #WhatIf You You Don't #Shower for a #Month?



Every #morning or every #night. Before going out. Definitely after the big game. For most #people, #showering is #routine. But for some, it's #religion. But if lots of showering makes you feel #divine, your #body might be the #real #miracle #worker. The average #human spends more than a #year of their #life in the shower. And according to most #dermatologists, that's way too much. But how else are you supposed to keep looking and smelling your #best?

- #WhatIf You Fell Into #Quicksand?



The #reason why you don't #normally sink into the #sand when you go at the #beach is due to a #physics #phenomenon known as #force #chain. Basically, when a #bajillion #grains of sand are #jammed together in one #place, their weight gets #distributed over a large area, keeping you and your #camels #safely above #ground. But if any #water happens to seep up from #underground, it will mix with the sand to #create a #surface that looks #solid, but isn't...

- #WhatIf We #Moved #Earth?



Some 5 #billion #years from now, the #Sun will expand and become a #red #giant. And the Earth might be just in the way... If #humans were still around then, would we #leave the Earth? Or would we move it? What is the Sun's #problem anyway? Like any other #star, it has an #expiration date. The #beginning of its end will feature our Sun swelling into a red giant, wiping out everything that happens to be #orbiting it too closely. Like the Earth.

- #WhatIf Every #Dead #Person Was Still #Alive?
https://invidio.us/vi/orHzEgiMa7E/maxres.jpg
What if you actually did see dead #people? Not in a #SixthSense #kind of way, but in an #inexplicable mass #resurrection kind of way? Not in a #WalkingDead kind of way, but in a "Holy #shit #Grandma's back!" kind of way. While this might sound like a #great #opportunity to catch up with #lost #loved ones, and to meet some of your #heroes ... It would actually be #horrible.

- #WhatIf One #Million #People Actually #Stormed #Area51?



If you happened to wander into the #Nevada #desert and stumbled upon the #secret #US #military #base, Area 51, you'd quickly be #arrested, #killed, or maybe even #abducted by #aliens. But what if you happened to #organize one million other people through #social #media to storm Area 51? They can't stop us all right? Or can they? And if you did #manage to get into the base, what would you #see?

- #WhatIf You Fell Into a #Pool of #Liquid #Nitrogen?



What would happen if you poured liquid nitrogen all over your #car? Or used it to #fight a #fire? Or even #tried to #cool down with it on a #hot #day? Liquid nitrogen may look like a lot of #fun when you're #watching #people dump everyday objects into it, but it's actually a very #dangerous #substance. And if someone were to dump you in it, the fun would quickly come to an end.

- #WhatIf You Were the First #Person on #Mars?



- #Congratulations, you've taken the seven-month-long #journey and have #landed on Mars. And it turns out, you're the first person. Better #start getting the #human #colonization #prepared. Will you ever make it back to #Earth? How will you gather #resources for #survival? And will this #happen one day?

- #WhatIf #Earth Was Near the #Center of the #MilkyWay?



See that #strip of #stars splashed across the #night #sky? That's our home #galaxy, the Milky Way. You can see it from Earth because we #live on its very outskirts, far away from all the #fun #stuff happening in its center. What would it be like to reside in its #galactic #downtown? Would we still have our #familiar #Sun? What would our night sky look like? Would we get #sucked into a #blackhole?

- #WhatIf We #Planted a #Trillion #Trees



It's #dawn, it's #dark, and you don't what kind of #weather is waiting for you #outside your #tent. It doesn't matter anyway. In #rain, #hail, #sleet, #snow, or #blistering #heat, you're on the front #lines, #shovel in #hand, wearing over 20 #kilos (50 pounds) of #gear, #battling against #nature to #save the #environment. On a good day, you might plant 2,000 trees in a 10 #hour shift. So why would anyone do it? Because if they didn't, #life would be much #worse ... for #everyone.

- #Whatif Earth Had Rings Like Saturn?


- #Jupiter ... #Uranus ... #Saturn ... #Earth? Sadly, the Earth didn't make it onto the list of the #Solar #System's #ringed #planets. If it did, would it still be #able to host #life? Having #planetary #rings visible in the #sky would look way more #spectacular than just one #grey #rock, right? Maybe. But if our planet got #beautiful rings like these #tomorrow, much of life on Earth might not #survive the #renovation #process.

- #WhatIf You Had #X-Ray #Vision?



Wouldn't it be #cool to see things through any #wall and any #door? How about seeing through your own #skin? Or your #dog? No, no, no, and no. Of all #superhero #powers out there, this isn't the one you want to get your #hands on. X-rays are #light. But they have #different #wavelengths than #visible light, and that makes them #interact with matter #differently. Basically, they can make some #materials #partially #transparent - like #human #tissue.

- #WhatIf the #Speed of #Light and #Sound Were #Switched?



Nothing can #travel #faster than light. But what if we switched the #rules a #little? #Imagine a #world, where the speed of light was #slower. Way slower. About the speed that sound #travels at. In #turn, the sound in that #hypothetical world would be #accelerated until it reached the speed of light.
How would the sound and the light #look?

- #WhatIf The #Neanderthals Had Not Gone #Extinct?



Neanderthal #DNA is 99.7% #identical to our own, and #researchers #claim that some #humans might be carrying as much as 2% of the #Neanderthal #genome. Making things even weirder is that #scientists recently #recovered a nearly #complete DNA #sequence from a 50,000-year-old Neanderthal #skeleton.
So in #theory, Neanderthals could make a #comeback. But how would they #adapt? And how long would they #survive?

- #WhatIf #Earth's #Atmosphere Was #Pure #Oxygen?



- #Imagine striking a match and having everything around you #catch on #fire, even if you were #standing in a wet #forest. And while that's #happening, imagine being chased by #giant #insects. These are just a few of the things that would #happen if you #lived in a #world where the #atmosphere is pure oxygen. What other things would happen on #Earth?

- #WhatIf the #Earth #Collided With Another #Planet?



Last #time a stray #planetoid the #size of #Mars #smashed into Earth, it scattered our planet's young #crust into #space, where #gravity #glued those #particles into what we now #call the #Moon. This time, it would be all #hellfire and #brimstone with no #survivors left. And here's a #timeline of how things #break down...

What If #Humans Were 5 #Meters (16ft) #Tall?



The #tallest #man to ever #walk the Earth was 2.72 m (8'9") tall, and he #quickly became an #international #sensation. So can you #imagine what #life would be like if you #grew to be almost #double that #height? How would you #navigate a #world #built for #smaller #people? Would everyone #treat you #like a #freak?

- #WhatIf Everyone Fell #Asleep at the Same #Time?



Everybody #loves a #good #sleep, but we #probably wouldn't enjoy it as much if we had no #control over when it #happened. #Imagine falling into a #deep sleep during a #first #date, in the middle of an #important #presentation, or #God forbid, behind the #wheel of a #car.
Now imagine #waking up and #realizing that the same #uncontrollable bouts of slumber are also happening to everyone else... at the same time... all over the #world. How would our world #change if we were all #forced into the same sleep #schedule?

- #WhatIf We #Lived In #Cities Under #Water?



Let's be #honest, we are pushing our #planet to a #climatechange #catastrophe. But there could be a #solution. 71% of the #Earth's #surface is #covered with water.
Why don't we make use of all that underwater #real estate? What would it be #like to #live at the #bottom of the #ocean?

If you ever find yourself falling into a volcano, there are a couple of things you should know. First off, when you reach the bottom, the #magma's not going to #swallow you up as it does in the #movies.

- #WhatIf #Orgasms Didn’t #Exist?



At any #moment of any #day, the odds are that someone around the world is having a #big O. We don't really #like to #talk about them, but they're an #integral #part of our #lives. #Billion-dollar #industries have been built around them. #People have become #addicted to them. And #scientists have #studied them for #eons.
So what would happen if we stopped having them?

- #WhatIf #Oxygen #Doubled in #Earth's #Atmosphere?



Take a deep #breath. We take 23,000 breaths a #day; trying to get #oxygen to our #brain and #cells. Oxygen is #essential to our #survival. But it's a only small #percentage of what's in the #air we breathe. So what if there was more of it? What would #happen?
Would it cause #giant #insects to roam the #streets? Would everything catch #fire? Would it make you #super #human?

- #WhatIf We Could #Control The #Weather?



What if we could #manipulate the weather just like that? Would there be no more #hurricanes, no #storms, and no #floods? Could we ease #climatechange?
And who would #decide what kind of weather to make? Here's what would #happen if we could control the weather.

- #WhatIf The #World Was A #Single #Country?



After #World #War II, where #humans wiped out #three #percent of the world's #population, #global #leaders began discussing the #idea of having one world #government to avoid #repeating the #mistakes made over the previous 25 #years.
The idea quickly #fizzled out, but they might have been on to something. What #problems could this #solve? Who would be put in #charge? And how could it all go #terribly #wrong?

- #WhatIf We #Trashed #Earth's #Orbit With #Space #Junk?



With every #rocket we #launch into the Earth's orbit, we're #trapping ourselves on our own #planet. Wait, how could sending rockets into space put an end to space #exploration?
And how #dangerous would it be to get #stuck here with all the space #debris floating above our #heads?

- #WhatIf You Could #Stop #Time?



If you had a #device #designed to #freeze time for #everything but you, #life wouldn't be anything like what you'd #expect. You wouldn't catch up on #sleep, or #rob a #bank while no one can stop you, or #cheat on an #exam.
Instead, you'd be left #blind, #deaf and #unable to #move a #single #muscle. How can time #freezing go so #wrong?
