Wtf is a megaparsec? It’s a million parsecs. Tf is a parsec? A parallax arcsecond.
…Tf is a parallax arcsecond?
An attempt at an explanation for the layperson
Imagine you’re standing outside. In front of you is a tree and behind that on the horizon is a mountain. You move 10 ft to your left, and the tree looks like it moved to the right, but the mountain looks like it hasn’t moved at all. That’s parallax. The closer something is, the more it appears to move when you move. Imagine you are the pivot point on a big protractor. Your field of view can be divided into 360°. Every degree can be divided into 60 parts, called arcminutes. Every arcminute can be further divided into arcseconds. Each arcsecond is 1/3600 of a degree. How do these fit together? There’s one more thing I need to explain. The earth orbits the sun at around 149.6 million kilometers. That’s called an Astronomical Unit. A parsec is the distance that an object would have to be, so that moving one Astronomical Unit would make it appear to shift sideways by 1 arcsecond.
It’s 3.26 lightyears.

Preemptive explanatory note: the speed of light, approximately 300,000 km per second, is the highest speed that something can move through space.
The expansion of space doesn’t happen at a set speed. It happens at a rate of approximately 70 km per second per megaparsec. So if you’re measuring two points half a megaparsec away from each other, then every second, the space between them grows by about 35 km. If you’re measuring two points 2 megaparsecs away from each other, then every second, the space between them grows by about 140 km.
If you’re measuring two points 4300 megaparsecs away from each other, then the spacetime between them grows by about 300,000 km every second. That’s not to say that anything is moving at 300,000 km per second, there’s just more space between them every second

Good news! We do have a nice big wall about a light second away! Hard to find a laser that’ll make a visible dot on the moon, though

Oh yeah, I’m fully aware. My own city made national headlines in my country a few years back when bastard pig Justin Rapp shot and killed Andrew Finch. SWATting should be considered attempted murder.
Fun fact! Bastard pig Justin Rapp sued the city when they placed him on leave, and won. Now he’s a detective whose salary is paid by my tax dollars. Fuck the police

In fairness, the police don’t have a list of who is in every house at all times. They don’t exactly have X-ray vision. All they know is that they got a call saying that someone is holding someone at gunpoint in this house.
Of course, 20 vans is comically overkill

What do you think it would look like from the outside if someone had you at gunpoint in your bedroom?

Asking questions and “just asking questions” are two different things in this context. “Why are Jews overrepresented in the media and banking industries?” is a perfectly valid and normal question. If you’re asking it with the intent to understand the sociopolitical context behind this factual statement, that’s good. If you’re asking it to try and push a narrative about Jews being in control of the world, that’s bad.

Fun fact! Police collectively make up a majority of cases of armed robbery,* and it’s totally legal for them
- Legally, civil asset forfeiture is distinct from armed robbery. Literally, they are the same thing.

Invincible has gone the same way
Yup. It doesn’t have to be written well anymore, as long as they have long, brutal fight scenes to keep fans happy. The animators really have a thing for intestines this season. That said, I have to admit that I am one of those fans that’s kept happy by those long, brutal fight scenes. Everyone on my couch was cheering while ____________ choked the fuck out of __________.
I think the biggest difference between the two shows for me is that The Boys is despairingly cynical, and Invincible is relatively optimistic. It seems like Robert Kirkman generally likes humanity, and Garth Ennis hates everyone and everything.
- Comment on Guess the director 5 weeks ago:
This feels like a thermian argument. In-universe explanations don’t justify racism on the part of the author. Plus, this is The Boys we’re talking about… Kripke had Hughie raped last season because he thought it was funny. Don’t give them any credit

You can tell he never intended to kill anyone by the fact that he had a bunch of guns strapped to his tank, and he drove into a building with children in it. The only reason he failed to kill anyone was because he was an incompetent piece of shit and the town was evacuated in time
