Let's dig in to some truly eyebrow-raising theories about aliens.
If there are so many planets, where the heck is everyone?

A video from Kurzgesagt digs into some truly eyebrow-raising questions about aliens. It starts with what physicists Enrico Fermi and Michael H. Hart got to wondering about. It's called the Fermi paradox, and it goes like this:
If...
- There are 100 billion galaxies just in the observable universe
- Which means there are 100 to 1,000 billion stars
- Which means there are probably trillions of trillions of livable planets, so life could be, like, everywhere
- And lots of these planets are older than Earth, so some of the theoretically more-developed folks/critters that might be on those planets could/should have figured out space travel by now
Then...
- Where are they already?
Well, far far far far away, if they exist out in the larger universe.
The universe is expanding, so it would take us billions of years in the speediest spaceship to get to anybody outside of our galactic neighborhood.

But if we think locally, it actually is possible.
In the Milky Way alone, there are likely to be about 4 billion habitable places to live.
And if just 0.1% of them actually have any life, that would be 4 million places somebody or something could be living. (The video incorrectly says "1 million." Hey, anyone can make a mistake.)
So the heavens should be teeming with spaceships.
So, um, where's the party? It may be due to those pesky things the video calls “filters."
For instance, maybe life requires a more particular set of conditions than we realize. Certainly, the universe hasn't always been very welcoming.
Maybe we're actually unique, or we could even be the first life anywhere.
Maybe some filters just make it really hard to keep living things alive. (Not to point any fingers here.)
It's also possible that an ancient advanced life-form has been watching us all along.
It could also be that we haven't seen anyone yet because that advanced life-form zaps away any civilization that advances to a certain point to preserve the galactic peace. Just saying.
But if we are alone, wow. That makes what we have even more important.
If we screw up this planet beyond saving, we could be eliminating the only life in the entire universe. Anywhere. Well, that's a big responsibility. After all, this universe is too beautiful not to be experienced by someone.

You just know there's a person named Whiskey out there getting a kick out of this. 


An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
