Extinguish Part One: Spark [Teaser for Tags List]

Pairing: Bucky Barnes x Reader [modern AU]

Summary: You’ve been best friends with Bucky for years, which wouldn’t be so much of a problem if, well—you haven’t been carrying a torch for him all this time.

or

With a sailor’s mouth and a reckless attitude, you put a twist on the ‘girl-next-door’ type. Ever since your family decided to take root in one of those suburban, cookie-cutter houses, you’ve been redefining your title by bringing a notorious reputation upon yourself—anything to break the apple-pie exemplar of a mold that you so desperately have to get away from. 

Childhood neighbor, Bucky Barnes, has been bailing you out of trouble time and time again. After all, you’re practically his kid sister. But when a fateful night causes him to reevaluate the situation in a different light, he’ll have to decide if sacrificing your friendship is worth the tempting burn that love never fails to deliver.  

Warnings: profanity, arrest, unrequited love, room for potential angst, friends to maybe-lovers trope  ¯\_(ツ)_/¯

A/N: It’s taking a lot longer than I expected to write this, so I thought I’d give the first two paragraphs of “Spark” if anyone’s interested in being added to the tag list (both perm or series open)

And this maiden she lived with no other thought
Than to love and be loved by me.
I was a child and she was a child,
In this kingdom by the sea;
But we loved with a love that was more than love-
I and my Annabel Lee
;  - Edgar Allan Poe

When Dead Stars Collide!

Gravity has been making waves - literally.  Earlier this month, the Nobel Prize in Physics was awarded for the first direct detection of gravitational waves two years ago. But astronomers just announced another huge advance in the field of gravitational waves - for the first time, we’ve observed light and gravitational waves from the same source.

There was a pair of orbiting neutron stars in a galaxy (called NGC 4993). Neutron stars are the crushed leftover cores of massive stars (stars more than 8 times the mass of our sun) that long ago exploded as supernovas. There are many such pairs of binaries in this galaxy, and in all the galaxies we can see, but something special was about to happen to this particular pair.

Each time these neutron stars orbited, they would lose a teeny bit of gravitational energy to gravitational waves. Gravitational waves are disturbances in space-time - the very fabric of the universe - that travel at the speed of light. The waves are emitted by any mass that is changing speed or direction, like this pair of orbiting neutron stars. However, the gravitational waves are very faint unless the neutron stars are very close and orbiting around each other very fast.

As luck would have it, the teeny energy loss caused the two neutron stars to get a teeny bit closer to each other and orbit a teeny bit faster.  After hundreds of millions of years, all those teeny bits added up, and the neutron stars were *very* close. So close that … BOOM! … they collided. And we witnessed it on Earth on August 17, 2017.

A couple of very cool things happened in that collision - and we expect they happen in all such neutron star collisions. Just before the neutron stars collided, the gravitational waves were strong enough and at just the right frequency that the National Science Foundation (NSF)’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and European Gravitational Observatory’s Virgo could detect them. Just after the collision, those waves quickly faded out because there are no longer two things orbiting around each other!

LIGO is a ground-based detector waiting for gravitational waves to pass through its facilities on Earth. When it is active, it can detect them from almost anywhere in space.

The other thing that happened was what we call a gamma-ray burst. When they get very close, the neutron stars break apart and create a spectacular, but short, explosion. For a couple of seconds, our Fermi Gamma-ray Telescope saw gamma-rays from that explosion. Fermi’s Gamma-ray Burst Monitor is one of our eyes on the sky, looking out for such bursts of gamma-rays that scientists want to catch as soon as they’re happening.

And those gamma-rays came just 1.7 seconds after the gravitational wave signal. The galaxy this occurred in is 130 million light-years away, so the light and gravitational waves were traveling for 130 million years before we detected them.

After that initial burst of gamma-rays, the debris from the explosion continued to glow, fading as it expanded outward. Our Swift, HubbleChandra and Spitzer telescopes, along with a number of ground-based observers, were poised to look at this afterglow from the explosion in ultraviolet, optical, X-ray and infrared light. Such coordination between satellites is something that we’ve been doing with our international partners for decades, so we catch events like this one as quickly as possible and in as many wavelengths as possible.

Astronomers have thought that neutron star mergers were the cause of one type of gamma-ray burst - a short gamma-ray burst, like the one they observed on August 17. It wasn’t until we could combine the data from our satellites with the information from LIGO/Virgo that we could confirm this directly.

This event begins a new chapter in astronomy. For centuries, light was the only way we could learn about our universe. Now, we’ve opened up a whole new window into the study of neutron stars and black holes. This means we can see things we could not detect before.

The first LIGO detection was of a pair of merging black holes. Mergers like that may be happening as often as once a month across the universe, but they do not produce much light because there’s little to nothing left around the black hole to emit light. In that case, gravitational waves were the only way to detect the merger.

The neutron star merger, though, has plenty of material to emit light. By combining different kinds of light with gravitational waves, we are learning how matter behaves in the most extreme environments. We are learning more about how the gravitational wave information fits with what we already know from light - and in the process we’re solving some long-standing mysteries!

Ok, so, Velma can’t find her glasses again.

Also, I’ll note that these two…

make absolutely zero attempt to help out in any way, shape, or form.

But then, Shag ‘n’ Scoob talk with Fred ‘n’ Daph about how they were running from the previously-established monster of the episode…

…the monster starts walking towards the gang, growling loudly about a paper, which Daphne hears clearly and comments on…

…and Fred – finally putting two and two together – calls out “That must be the Creeper! Run!”

Naturally, they do the only sensible thing…

…and instantly ditch Velma without a second thought.

Yup. Left her for dead. They don’t even look back.

But then, Velma says:

What’s going on around here? Run from what?”

…wait, even though she was right there when the others heard the monster? 

…and was right there when Shaggy talked about the monster?

…and when Fred literally said it must be the monster that they were all worried about?

So… in addition to magically being unable to see even basic shapes or differences in light without her glasses…

…can Velma not hear without her glasses, too?
