@aakashgupta Wrong: The steepest temperature drop humans ever engineered was between the apple cobbler and the green peas in a 1980s TV dinner.

Look at this astronaut's face during reentry, knowing the capsule exterior is at 5,000°F. The physics of why he's alive are wild. The air in front of the capsule compresses so violently at Mach 25 that it turns into plasma. 5,000°F on the surface. Half the temperature of the sun. The heat shield absorbs that energy by literally burning itself away, layer by layer, carrying the heat with it as gas. One inch of material is the entire margin. On the outside of that inch: 5,000°F. On the inside: 75°F. Room temperature. The thermal gradient across that single inch is the steepest temperature drop humans have ever engineered. The orange glow in the window is ionized nitrogen and oxygen. That plasma is why comms go black for six minutes during reentry. Ground control can't reach the crew. The astronauts are alone inside a fireball, falling at 25,000 mph, watching the laws of thermodynamics keep them alive through a 1-inch wall. Artemis II did exactly this last night. Four astronauts hit Earth's atmosphere at 24,664 mph, rode a 4,900°F plasma sheath for six minutes of radio silence, and splashed down a mile from target. The heat shield is now being inspected for cracks. They found over 100 on the last unmanned test.

@shanaka86 Army CoS has no say in the conduct of the war. His is an advisory role. Commander of Centcom is in charge of prosecuting the war.

JUST IN: You do not fire your Army Chief of Staff in the middle of a war for no reason. You fire him because of what comes next. Pete Hegseth called General Randy George on April 2 and told him to retire immediately. The Pentagon confirmed it within hours. No reason was given. Not publicly. Not privately. A senior Army official told Fox News that Hegseth offered George nothing: no misconduct, no operational failure, no policy disagreement on the record. Just a phone call and a career ending in the middle of the most significant American combat operation in two decades. George is the 24th general or admiral Hegseth has removed. But he is not the 24th. He is the one that matters. The Army Chief of Staff. The man whose signature sits between a president’s intent and the order that sends soldiers across a beach or into a tunnel complex. The 82nd Airborne is deploying right now. Marines from the 31st MEU are staged on the USS Tripoli. JSOC operators are at forward bases in Israel, Jordan, Saudi Arabia, and the UAE. Kharg Island, 90 percent of Iranian oil exports, sits 16 kilometres off a coast that someone will have to decide whether to approach. And the four-star general whose job it was to advise whether that approach should happen was removed 48 hours after Trump told the nation the war would continue for two to three more weeks. The replacement is Vice Chief General Christopher LaNeve. He was Hegseth’s senior military aide before this appointment. The man who carried the Secretary’s briefcase now commands the Army the Secretary is reshaping. The chain of command did not break. It shortened. The distance between a television studio and a combat order just collapsed to zero intermediaries who were not personally selected by the man giving the order. No reason was given. That is the tell. When someone is removed without explanation during a crisis, the explanation is the crisis itself. George either objected to something or was about to. The ground option. The power plant strikes. The Kharg raid. The escalation that turned a highway bridge in Karaj into rubble on the same day he was told to leave. Something in the next two weeks requires a chief who will not push back, and the Pentagon solved that problem by installing one trained as Hegseth’s aide. A former Fox News weekend host just fired a four-star general with combat tours in Iraq and Afghanistan, replaced him with his own former assistant, and did it during a live war in which the next decision could put American soldiers on Iranian soil for the first time in history. No hearing was held. No misconduct cited. The Army woke up on April 3 with a new chief it did not choose, in a war it did not start, preparing for a phase the previous chief apparently could not be trusted to execute. The question is not why George was fired. Every general in the building knows why. The question is what order is coming in the next fourteen days that required removing the one man in the chain of command who might have said no. The war has no perimeter. The chain of command has no objectors. And the next phase has no one left to stop it. open.substack.com/pub/shanakaans…

@KrisztinaMaria I think you should probably sell Greenland

Let me ask my American friends for a moment. When Danes react with fear and genuinely believe that Trump is going to start a war with Denmark because he wants to “steal” Greenland, it honestly seems ridiculous to me. From where I’m standing, this looks like a narrative whipped up by the media and reinforced by our government. But feel free to enlighten me….what do you actually hear, see, and think over there?

@WallStreetMav Don’t threaten me with a good time

So let me get this straight ... If we just take Greenland, Denmark and other NATO members will kick us out of NATO, we bring home 80k troops and we save $50 billion per year, no longer having to defend Europoors and they have to pay for their own defense? Sounds perfect

@blkojo @airmainengineer None of the U-2 pilots in the footage went on to fly the SR-71. Judging from the uniforms of the PSD troops, the footage is from the 20-teens at the earliest. The SR-71 was retired (for the second time) in 1997.

@speedyb97 @airmainengineer At least half of the early SR-71 pilots came from the U-2 program. My father put them there.

The SR-71 Blackbird wasn’t just fast… it was a machine that literally OUTRAN missiles. 🚀🖤 Here’s why this aircraft is still unmatched today 👇 The Blackbird could fly at Mach 3+, over 85,000 ft, with a skin temperature so hot the jet expanded mid-flight. 🔥 It leaked fuel on the ground because the titanium panels only sealed when heated at speed. 😳 Its engines—part turbojet, part ramjet—were so advanced that after Mach 2.5, the shockwaves did most of the compression work. Pure engineering magic. ⚙️✨ And here’s the crazy part: No SR-71 was ever shot down. Every time a missile was launched, pilots simply pushed the throttles forward… and outran it. 🏃‍♂️💨✈️ Built in the 1960s. Still futuristic today. A masterpiece that flew faster than the edge of human imagination. 🖤 What should I cover next? Another legendary aircraft? 👇🔥 📸 by ig/jet.nerd

@Keir_Starmer I think you’re on here just to get ratio’d

Digital ID will bring the UK into the modern age.

@GigaBasedDad ARE the crusades justified. Fixed it for you, and the answer is yes.

Were the Crusades justified?

@GadSaad There is a daily genocide of women and people of color; it’s called abortion.

My daughter's class is going on a school trip to NYC. Many of the parents are incredibly upset that the school would visit the United States where there is a "daily genocide of women, trans people, and people of color." The parents are not upset at what is happening in Canada or that @ZohranKMamdani is going to become mayor of NYC. They are terrified for their children's safety because of @realDonaldTrump. I have spent my entire academic career studying human behavior and human decision making, and yet I'm astounded by this level of suicidal stupidity.

@Jesse_Bibi @Grok what movie is this

Google me might just be the biggest flex ever

@innoutburger_ Arkansas

In-N-Out currently has locations in Arizona, California, Colorado, Idaho, Nevada, Oregon, Texas, Utah, Washington, and Mars. Where should In-N-Out open next?

@allie__voss Any man could tell that woman was not peace

“Men just want peace” turned into “Men just want peace and a woman whose voice is attractive and who dresses sexily and doesn’t travel and is NOT under ANY circumstances scuba certified” real quick

Went to @bucees for the first time. I don't see a reason to go to any other store again. Ever...

@jarvis_best This has got to be the dumbest thing I’ve read on the internet today. And that’s saying a lot.

@davishouz @TRHLofficial Let her cook

@TRHLofficial You're cooked now 😅😅😅

Grok Imagine, make me into another scandal.

@innoutburger_ Memphis is not a nice city. Not as bad as Oakland, but I wouldn’t be overly surprised if the In n Out closed for the same reasons.

I've never been to Memphis. Cool place to go to?

@Nero You were a bug chaser?

You say that, but I tried—and I didn’t. There is no satisfactory explanation as to how and why I didn’t get HIV. It defies math, physics, biology and chemistry. Four figures’ worth of unsafe encounters with the highest risk group, over half of whom get AIDS. Not one solitary crab

@BillsMafCanRep @JazOutaControl @grok Then fold the whole league. As a payroll manager you should be able to understand fixed and variable costs.

@JazOutaControl Hey @grok is the wnba profitable.

@innoutburger_ Switch to beef tallow

You’re the CEO of In-N-Out for 24 hours. What’s the first thing you’re doing?

@Rothmus 2.375% baby!!
