Have cats always been able to defy gravity?

why do beeg planets have so many moons

I think gravity is an illusion btw

Sorry but they do because of gravity, and I refuse to argue with people who don't believe in gravity because they keep floating away before I can explain that they're wrong.

Okay so I wanna take a moment to talk about gravity. Now I know what this sounds like, but bare with me here I promise I'm not looking to do a physics lecture. But I've been rotating this around in my head for a couple days now and I think there's something really critical in the way the show presents it to us.

For example: it's one of the few things actually listed in our introduction to this show individually while our protagonists build the universe, right between matter and everything else.

The show draws our attention to it here fairly bluntly by naming it but there are other incidents that, while I would not call them subtle, are not quite as on the nose.

There are at least three times Crowley chucks something he's holding in his hands across the room. They're played for comedic bits but they all feel very weird and pointed to me - especially both times he does this to books that he seems to have no purpose for holding other than to chuck them later. It caught my attention mostly because everything in me recoiled at the idea of him doing that, but the more I thought about the way they're so visible and pointed was important. They almost feel like weird hiccups in the scene they're in.

We also get gravity as an implied threat with Gabriel climbing out the window and, of course, with every mention of a Fall. But there's also more mundane uses of gravity in the season that while not odd in isolation, the fact we get it popping up so notably is interesting to me. There's also the scene with Nina and Maggie under the awning where rainwater's weight gets pulled down by gravity, the scene in 1941 where Aziraphale drops the picture of them onto the floor before they have their gray area talk, Gabriel dropping the matchbox, and I'm sure there's more. The point is the show is littered with reminders that gravity exists.

Now I know what this sounds like. I know it seems like yeah. Duh. They're on earth. Which has gravity. Of course gravity is a factor in nearly every physical action they do. Why are you even talking about this at all?

Well, it's because of a scene that is one of my absolute favorites in the whole season: the Gravity Lesson.

The scene opens with Jim throwing a book (My Best Games of Chess, an interesting title that feels pointed) repetitively at a desk. He's testing gravity himself, looking confused.

Crowley then descends from the upper level, carrying a stack of books. He pauses his descent on the spiral staircase and notes what Jim is doing.

Then we get this shot. Notice the light here. Jim is in the light from the windows but relatively in the middle of the shot. He's an angel still, though not nearly as in the Light as he was as Gabriel. And he's notably at ground level, on earth. Meanwhile Crowley blends into the shadows of the shop itself. He continues down the staircase, sauntering vaguely downward, until he finally hits earth level to be even with Jim. There's symbolism here, in the lighting, in the way they move through these frames, in the way the staircase spirals like an orbit.

Crowley continues this same sweeping circular pattern to come around the bookshop and place him in front of Jim. Unable to resist a question, even one that wasn't asked out loud, Crowley tells him about gravity. He moves center toward Jim here. A meeting in the middle. This is the first scene we see Crowley interact with Jim in a way anything near amicable. He explains how gravity works. "It's, um... A thing that happens when objects are pulled together. In this case, they're all pulled downwards because Earth is the largest thing around."

As he speaks, Crowley moves away from Jim, toward the back of the bookshop. But he stops very rapidly because Jim goes and asks him why. Crowley frowns to himself. He says he can't remember. He says it seemed like a good idea when they were all talking about it.

He walks back to Jim, giving this question some real thought, and settles on, "So things would stay where you put them, not just drift off." And Jim, backlit by the windows still, kind of frowns and drops the book again and points out. "But it doesn't stay where I put them. It goes down."

When the book hits the table it also visibly does not land precisely over where Jim dropped it either. It settles out of place, bouncing slightly from the force of it. This is what drew my attention to this scene more than anything else.

Because it's interesting isn't it? They're both right in their assessment here. And so much of this story is about people not fitting quite where they're dropped. Aziraphale and Crowley are both caught in Earth's gravity, jostled out of their respective places. The very first shot in the intro sequence emphasizes this idea. Crowley and Aziraphale meet in the middle on earth (where Crowley then says let there be light and lights a flame to guide them going forward).

Gabriel and Beez too fall out of line as soon as they get caught in Earth's gravity. Memories are deleted, but can't entirely escape the gravity of their old home. Memories are added, but you can't predict exactly the way they'll form. Miracles backfire and don't land quite as they're expected. We obey Heaven or Hell as far as we can, but not necessarily exactly as they'd like. These shifts eventually become predictable and eventually we learn we can calculate the odds of how gravity can impact something, but as Jim shows us here a little bit of the drift still happens. In the end it's all just firing bullets at ears and pretend to catch them in our teeth.

And there's viewing this line of thinking from the perspective of God. God who functionally dropped the universe into the gravity of Fate and Choice just to see where it would land.

And then there's the Fly.

As Jim points out here, some things actively resist gravity, at least temporarily. Flies go up. This is very fun, given Beelzebub's arc this season, but I think it's getting at more than just that. Crowley and Jim both pause to watch the fly rise upward, drifting away from Jim and toward the dark half of the shop. Crowley says Jim makes a good point and then shifts into "Right, the plan, Operation: Lovebird."

Given the plot of season 1, I find the use of the word plan here pretty interesting. Especially given that the event that follows this is Crowley trying and failing to get Nina and Maggie to recreate his own meet cute. Like the idea of these two being drawn together will fix everything.

And that got me thinking about Crowley's line at the end of season 1. About what if God planned it that way. What if they're God's own Operation Lovebird. We know that together they can do very powerful things. This whole season starts with them, while trying to keep their power under control and contained, do a miracle so big it could've brought someone back from the dead nearly 25 times. Last season ends with Heaven and Hell thinking they've become something impossible. The Metatron here goes out of his way to separate the two of them like he's afraid of what they're capable of together. And he seems to have successfully managed to do this.

But a Fly can't stay in the air forever. The Fly is always drawn back to Jim. Because not all gravity is about Earth itself. The same way Gabriel's memories are drawn back to him. The same way Beelzebub and Gabriel are drawn to each other in the first place. The same way Aziraphale and Crowley have been described time and time again as drawn in by each other. They're Alpha Centauri. Twin stars orbiting each other. They're constantly going in circles around each other. It's a dance. With the hands touching in the middle. Because that is a gravity too. They complete each other the same way the Fly completes Jim.

So what about choice? Think about the Ball episode. Think about how everyone in the shop is being influenced by some sort of miracle. Their clothes and behavior shift and change and Nina in particular shows us that this is Noticeable. Forcing something in a gravity it doesn't like or want makes it have a hard time settling. It doesn't go quite where you drop it.

And then there's the chat Nina and Maggie have with Crowley. "We're not a game. We're real people," says Maggie. And Crowley tries to argue this saying that they both needed help and they both push back that it is still not his right to meddle with. A game. Like the title My Best Games of Chess. Like the thing we know God has been using as a framing device since season 1. A thing the narrative always has pushed as a bad thing.

Maggie and Nina are choosing to not let beings above them influence their choices. They actively resist being compelled by Aziraphale in the bookshop together because they know what's right. His gravity is not enough to overwhelm their choices. And at the end maybe they're not together but they're working on it. And, maybe, if they do come back together (when they do, according to Maggie) it will be when they are ready and when they are choosing each their free of the constraints of the game or higher power. And that gives me hope that's where we're headed for the Ineffables as well.

hello! i've got some GROUNDBREAKING space news for you!

scientists have uncovered evidence for a gravitational wave background (GWB) in our universe, and the way they went about it is fascinating.

To fully understand what's going on here, we need to go into a bit of background information.

First of all: what are gravitational waves? gravitational waves are often called 'ripples' in spacetime, often caused by extremely energetic processes such as black holes colliding, or two neutron stars orbiting each other closely.

So, how did scientists figure this out? They used 67 pulsars (known as the Pulsar Timing Array) throughout the Milky Way, practically creating a galaxy-sized telescope in order to study this.

Pulsars are the extremely dense cores of massive stars, left over after they go supernova. These are fascinating on their own, but for this project, they had an essential feature: Pulsars rapidly rotate (think up to hundreds of rotations per second), spewing radiation out in pulses from their magnetic poles. For some pulsars, these radiation jets cross Earth's line of sight, and we get incredibly constant bursts of radio signals, which can be catalogued and used as a sort of standard, universal clock.

Here is a link to a gif showing the rotation of a pulsar. Please be warned for flashing and eyestrain.

For 15 years, a team of astronomers working for the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), used radio telescopes around the globe to track minuscule changes in the signal patterns from pulsars. The changes they found are due to the slight movement of spacetime between us and the pulsars, stretching and compressing the paths of their radio waves as extremely low frequency gravitational waves pass through the universe (yes, that includes you. your atoms, as well as the atoms making up everything around you, are very slowly shifting position, dancing along to the heartbeat of the universe).

At the moment, scientists are still debating what could have caused this gravitational wave background, but some there are some leading theories: the GWB could be caused by trillions of binary black hole systems (black holes orbiting each other) throughout the universe. It could also be due to cosmic inflation, or even the big bang itself. Scientists just don't know yet, but the opportunities this discovery opens up are incredible.

The knowledge of the GWB could help us better understand the formation of early galaxies, or even help us understand the origin of the universe.
