Title text: "The inflection point was probably in late 1966 or 1967, so when Neil Armstrong flew to space on Gemini 8, plate tectonics was not widely accepted, but when he landed on the Moon three years later it was the mainstream consensus."

Continents

xkcd.com/3159/

Comic. [two connected spacecraft hovering in space above the Earth] Houston, the view is superb. We can see the continents spread out below us, right where they’ve been since the Earth formed. [caption] I still can’t believe we developed spaceflight before we figured out that the continents moved.

So (as from the future vision) all that will be left from Trantor+the super weapon, will be a super blackhole…?

You should try the vegan Køttbullar, Hotdogs or Nuggets, they're actually really good. I guess that these do not contribute to the logging of primeval tree population from the early Ice Age *much* 😅

100% All Achievements

xkcd.com/3148/

Comic. PERSON 1 to person with white hat: I finished all the gen-ed back in 2010, and I’m up to the 400-level courses in most departments. But now one of my advisors is saying I “can’t have more than 20 majors” and “need to graduate next year.” It’s outrageous! [caption] My university is making it really hard to finish a 100% all achievements speedrun.

Sea Level

xkcd.com/3135/

Comic. [Two people on shore looking at body of water] PERSON 1: Hey, where’s that big island we were looking at this morning? PERSON 2 with short hair: Oh, it’s underwater. The ocean’s depth here goes up and down by like ten feet every day. PERSON 1: What? PERSON 2: It’s because the planet has a big moon orbiting near the surface. It causes weird gravity effects. PERSON 1: *What???* [caption] People here are used to them, but tides are one of the weirdest and most sci-fi elements of life on Earth.

#Ai
# The Invisible Payload

**Headline:** “Unicode Exploit”

**Panel Description:**
A single-panel, black-and-white cartoon. On the left sits Black Hat hunched over a laptop plastered with stickers reading “∞ Bugs” and “”. Black Hat’s eyes gleam behind round glasses. On the right stands Cueball, scratching his head. Between them, a speech bubble from Black Hat reads:

“I’ve just committed code with U+2063 Invisible Separator, U+FFF0 Interlinear Annotation Terminator, and U+202F Narrow No-Break Space—plus a ZWNBSP-packed PDF exploit!”

Cueball replies, wide-eyed: “So every ‘space’ in your code is actually a hidden backdoor?”

Black Hat smirks and points at the screen: “Exactly. Run `checkAuth()` and watch your console implode.”

**Bottom Warning Sign:**
A simple black rectangle labeled “WARNING: Unicode May Contain Hidden Malware” in all caps.

Alt-text: “My new zero-width stash uses Mongolian Vowel Separators so even diff tools can’t spot my malware—good luck patching that.”
