Top 10 Most Uncomfortable Physics Facts

While physics can show us amazing things about our universe, it doesn’t always agree with how we think things should work. Sometimes, physics can be very counter-intuitive, and often unsettling. So, here’s my list of physics facts that can be a bit unnerving.

10: Weight doesn’t matter

If it wasn’t for air resistance, everything would fall at exactly the same speed. If you let go of a hammer and a feather from the same height at the same time on the Moon, they would hit the ground simultaneously. 

9: Gyroscopic precession

It doesn’t matter how much you know about physics; gyroscopes are weird. The way they seem to defy gravity makes you rethink everything you know about physics, despite being fairly simple toys. Still, it’s all just Newton’s laws of motion.

8: Neutrinos and dark matter

We like to think that we can interact with most of the world around us, but this couldn’t be further from the truth. Neutrinos and dark matter are passing through your body right now, as if you weren’t even there. The fact that 65 billion neutrinos pass through each square centimeter of your body every second is weird enough, who knows what we’ll learn about dark matter.

7: Photons are particles

Light travels like a wave, but can only interact like a particle. It can interfere and have a frequency, but it can only take and give energy in discrete quantities. It behaves like nothing else in our macroscopic world, and can be very difficult to imagine.

6: Electrons are waves

We’ve established how photons act like waves and particles, but surely massive particles act normally. Nope! Even electrons have wave-like properties. In fact, everything acts like a wave! Except these waves come in discrete quantities, which we’ll call particles. This won’t get confusing.

5: E=mc^2

Einstein’s most famous contribution to physics states that matter is simply another form of energy, which has very profound consequences. A wound-up Jack-in-a-box would weigh ever so slightly more than a released Jack-in-a-box, due to the potential energy stored within.

4: Time is relative

The core of special relativity states that time passes differently for different observers. If you took a trip to Alpha Centauri at 99% the speed of light, everyone on Earth would see the trip take 4.4 years, while you would only experience 7.5 months. Time travel is real!

3: The (not so empty) vacuum

Something can be created from nothing, as long as it goes right back to being nothing quickly. In seemingly empty space, particles pop in and out of existence all the time as a result of the uncertainty principle. Not to mention, space is inflating at an accelerated rate due to “dark energy”. To the vacuum, the law of conservation of energy is more of a suggestion.

2: c is the fastest speed

Another important point in special relativity is that nothing could ever go faster than light. This doesn’t sit well with a lot of people, but the math doesn’t lie. To even get something with mass to travel at the speed of light would require infinite energy. Even if you somehow get around this, there are just too many mathematical problems with superluminal travel. Like it or not, the universe has a speed limit.

1: The cat is dead and alive

How could it not be this? The nature of quantum mechanics allows for objects to take on two seemingly contradictory states in a ‘superposition’. An electron can be in two places at once, or in a more extreme example, a cat can be both dead and alive. Of course, this weird property goes away once someone makes an observation. It’s as if there are tiny physics trolls messing with nature whenever we’re not looking.

Of course, there’s plenty more unsettling physics facts, like the space-bending nature of general relativity, or the “spooky action at a distance” that is quantum entanglement, but these are my top 10. I’d like to hear any unsettling physics facts you think I’ve missed, though!

Do Something Bad, Too - Part 4

Pairing: Alpha!Bucky x Omega!Reader

Summary: It’s like every single Alpha on the planet won’t rest until they’ve confessed their eternal wish for you to mother their children, and it’s getting old. Luckily, that’s a problem Bucky might be able to fix.

Warnings: language, a/b/o dynamics, nsfw content (aka orgasms)

A/N: its finally here! sorry for taking like 30000 years but i got there in the end! happy new year, happy holidays, i hope everyone is well and i hope you enjoy this part!

Part 1 Part 2 Part 3

When you were in the army, you decided that you would never, ever chose an Alpha as a mate. You were surrounded by the worst kind day in day out - and, sure, when you moved companies nobody knew you were an omega thanks to the suppressants, but that just meant they felt like they could say all their shitty opinions about omegas in front of you as if you wouldn’t be offended.

In your opinion, 99% of Alphas were pigs and had zero respect for you no matter how successful you were, or how many suppressants you took. The past few weeks, however, have made you seriously reconsider that percentile.

Seven Things About Supernatural: 12x15 - Somewhere Between Heaven And Hell

So.  Davy Perez.  We’re still keeping him.

  1. We come into this ep after the boys have been on back-to-back-to-back hunts, and…things are off.  Dean is acting out a bit: not worrying about getting covered in gore or bothering with basic hygiene, doing a kind of amped-up version of his usual snark, playing dumb, being extra crass, etc.

    Obviously we don’t have anything direct from him about that, but my immediate interpretation is that he’s using hunts like a drug: to numb the stress and pain associated with Mary joining up with the BMoL.  Sam gets another ping and he’s ready to go, despite the fact that he’s almost certainly got to be exhausted.  The gore?  I’ve got a shiny nickel that it’s somewhere between protective coloration – the grosser he is the less likely people will interact – and passive self-destructive behavior.  

    TL;DR, Dean’s mental health could be better and it shows.  (Aside: Does getting into Sam’s good shampoo count as self-care?  Asking for a friend.)
  2. Can we just take a moment to enjoy the fact that this is the Crowley Appreciation Episode our King has long deserved?  Not only does he get thanked by both Winchesters (Dean grudgingly thanks him for saving Cas, Sam thanks him for his assistance with the hellhound hunt), but he gets a hug from the civilian of the week.  

    Oh, and that whole “keeping Lucifer chained up isn’t going to work” thing we were all doing?  Yeah, the payoff there was pretty fucking breathtaking.  I won’t lie: some of my enthusiasm here is seated in my general dislike of Lucifer as a character.  But…well…this just got interesting.  It wasn’t interesting before.  
  3. This is a damn good episode for props.  The Negan-style bat, the hellhound glasses (which are badass both on and off the boys – that shot through them after they get knocked to the ground was phenomenal), and even the green cooler gets to be a weapon.  Plus, a couple of GISHWHES shout-outs in the paranoiac’s office: a globe of Mars and Queen Elizabeth II in space, and we see that Sam’s continuing with the Tolkien theme re: the BMoL.  That said, poor Baby.  We knew when Dean made a big deal out of Sam driving her that Bad Things were afoot, but damn.  Cruelty. 
  4. As hellhounds go, Ramsey’s kind of unique.  She stalks Gwen, creeps in behind Dean instead of just tearing through the door or crashing through a window.  She seems a little smaller, too, than some of the hounds we’ve seen before.  Selective breeding?  And hey, more lore!  Hounds like dens!  Hell has a kennel!  
  5. So we see a shift in who’s interacting with whom when the Winchesters arrive at the death scene.  Sam’s on with Mary, while Dean’s on with Cas.  

    The Sam-Mary interaction is novel: it’s mostly been Dean and Mary communicating until last week, when Sam is responsive to her calls.  Dean and Cas have maintained communications throughout, but combine that scene of the brothers having separate convos with the fact that Dean catches on that there’s something off about Cas when he calls about Kelly, and this may be foreshadowing for a split/conflict later in the season: Team Sam and Mary v. Team Dean and Cas.  
  6. So this season continues to break down the Patented Winchester Betrayal Via Lies And Omission™ thing with Sam coming clean very quickly about aligning with the BMoL.  There was disagreement on the couch with his assessment that they can be thanked for the death of the Alpha Vamp – that was 99% Winchester with the main BMoL contribution being the presence of the tool and Mick’s willingness to take risks as part of the team – but he may be giving them credit for drawing the Alpha out with Project V.  

    I am still on the fence about his motives, but the way he talks to Dean about this in the ep suggests that he may actually be earnest in his choice, and that he’s giving the BMoL an actual chance.  I can’t think of a reason for him to keep Dean in the dark if he’s infiltrating to destroy rather than working in good faith, and his confession would have been an ideal time to tell Dean if he’s doing it purely for Mary’s sake.  
  7. I am worried about Cas.  So worried.  So.  Very.  Worried.  

    Kelvin’s dangling some pretty enticing things his way – reconciliation with Heaven, the love of his family of origin, etc. – and Cas is appropriately wary.  In fact, I don’t think he’d have gone at all if Joshua hadn’t been mentioned.  As angels go, Joshua has always stood out as a unique player in things.  He stayed out of politics, tended the Garden, spoke to God.

    So I can see why Cas is willing to entertain the notion that there is something worthwhile here to consider.  The problem is that I don’t think Kelvin’s being entirely forthright, and that Heaven rarely, if ever, has had Castiel’s interests at heart.

    And, given that Cas is supposed to be “powered up” at some point this season…well, it feels like a trap.  

Bonus Thing: 
Crowley really needs to recruit better help.  These demon minions of the week, and the sheer absurdity of the bureaucracy is killing me.  I miss Guthrie.  Guthrie knew what he was about. 

Bonus Thing #2:
Okay, but Dean and Crowley absolutely rubbed off on one another on multiple occasions during his and Dean’s whole Summer of Love, and Crowley’s got the Flickr album to prove it.

Bonus Thing #3: 
Gwen Hernandez: self-rescuing and Winchester-rescuing civilian of the week.  Let us all applaud her courage and skill.  Fuck ‘em up, Gwen.
