What that James Webb image really means. Full video here:

Here's a 1-minute video showing--in the words of visualization hero @EdwardTufte--the "compared to what" factor for today's amazing @NASAWebb image. Thanks to the @WWTelescope for making this possible, and @ADavidWeigel. I only wish @NASA and @POTUS had shown the image this way! https://t.co/ThqLJqCUMa pic.twitter.com/4Yd6CIRcst

The first JWST image is creating quite a buzz around gravitational lensing because of the sheer amount of it in the image. Gravitational lensing makes galaxies appear warped like these:

A very small section from Webb's first Deep Space. The background is black space and a few galaxies and stars are scattered across it. The focus is on a red-orange galaxy that is warped and appears to stretch down in an arc which then stretches into a mirror image of the same galaxy.
A very small section from Webb's first Deep Space. The background is black space and a few galaxies are scattered across it. The focus is on a yellow-orange galaxy that is warped. It is elongated, bulbous on both ends and squeezed in the middle. The squeezed part arcs around a large, white spot.

Because spacetime curves around a massive body, light bends when it's near enough a massive object, allowing us to see very distant galaxies behind the cluster we're looking at.

An illustration on a black background. Around halfway it is divided horizontally. The lower half is a blue grid with straight lines except for the center, where it appears like fabric being weighed down. In this spot a couple of white dots represent a galaxy cluster. To the left of that and slighty up so it sits above the horizontal line is a white swirl representing a galaxy. Towards the right of the cluster and slightly down (but not weighing down the grid) is a circle representing Earth. Several white lines are drawn from the galaxy on the far left in the direction of the Earth. They represent disoriented light rays and are slightly bent around the galaxy cluster. Two red lines are bent around the galaxy cluster and meet again on the other side hitting Earth. Where the red lines are at the same level with the galaxy cluster they are labelled "lensed galaxy images". The graphic represents light rays from a distant galaxy being bent around a galaxy cluster due to its massive gravity which bends space time and some of those light rays being bent just the right way to reach Earth, creating a distorted image of the galaxy behind the cluster.

Here is some recommended reading on it if you wanna learn more:

"If you go on T you won't look like a pretty anime boy, you're gonna look like an ugly man!" is so funny because I'm SE Asian, have been on T for 3 years with subtle (but satisfactory) changes, and definitely still have been told I look like an anime boy or a K-pop idol (because racism.) I do like to take care of my appearance and make an effort to look nice and stylish, but that's not a "pretty anime boy" or "K-pop idol" thing, I'm just A Guy who wants to look nice and pretty and cool. It's such an odd statement cause from my perspective it definitely does not consider the experience I described above, LMAO. It's assuming a "little white girl who doesn't know any better and likes anime" person, or something like that. (Just putting this out there because transmascs of color definitely need to be heard more, and transitioning on T experiences are all very very different.)

And anyways, the condescending way people talk down to trans men who do want to look like their cute/pretty fictional men transition goals is so weird... Like, what's wrong with that, anyways? Some fictional guys are really designed nicely, and may give new perspective on masculinity or maleness that people IRL may not show depending on where you live. Anyways, I think even if T changes you to be more masculine than you expected, you can still present in a way inspired by characters and styles you admire if you so like.

And the other side -- what's wrong with looking like an "ugly" man? I feel like that's saying any masculine trait is "ugly," so if you think that please reevaluate yourself. Looking more like a man Is Kind Of The Entire Point. Many transmascs will embrace that masculinity, and that's not anything bad, wrong, or poisonous. If you think it makes them look uglier or more like a predator or enemy, I want you to know that is not a very kind mindset to have toward transgender people, or to any man in general; it's rather in poor taste, and shows you are not an ally to transgender people. So if you do desire to be an ally, I urge you to reevaluate yourself and challenge yourself on what being a "man" entails, what being "masculine" entails. Because it's not inherently immorality or ugliness, it's just a gender.

This framing of masculinization as something to be warned against, that we don't know what we're getting into is not very cool, definitely ignoring we have our own agency and choices and feelings about our bodies. Like, when we go on T, often we know what it will do to us, and what kind of person we are gender-wise. We're making that choice for ourselves, absurd that we're treated like we don't know any better. We know. Don't treat it like a warning that we'll become less desirable types of people.
