    Hollywood showing things instantly exploding or shattering the second they hit a vacuum does that to us, but the actual physics of space and the biology of cells are a lot tougher than the films make it seem.

    Neither the human body nor the bacteria inside it would burst, and the cold space environment behaves much differently than some expect lol

    The pressure difference between the inside of a human body and the vacuum of space is exactly 1 atmosphere (which is not that much in the grand scheme of things).

    And bacteria are tiny tanks, because they are microscopical, the physical forces acting on them are minuscule. Scientists have tested exposing bacteria directly to the vacuum of space outside the ISS, and many species survived for years.

    And about the cold, because space is a vacuum, counterintuitively, heat is actually hard to lose lol, it can only escape slowly through thermal radiation (there is no cold air to whip past and steal heat away), so they would still be gradually working for some time. And even when finally reaching extreme cold, we usually think of it as destructive, but for microbes it’s actually “preservative”. When Labs want to keep bacteria alive for decades without them changing or dying, they freeze them. So a lot of them wouldn’t even die, but stay “suspended”.






















  • There are a lot of European brands missing on that website, and judging by the plethora of random small American ones, I assume it’s probably because it’s made by an American.

    It also weirdly puts Tony’s in the boycott section, when it’s basically the only big brand trying to actively change their whole supply chain (there’s still progress to be made, but putting it alongside Nestlé? really?).

    In any way, it’s good advice in the end.


  • Plain false.

    Besides Lindt, which is publicly traded and has a minor share of American investors, almost all the other brands are family owned, which is rare in the modern food industry (Kinder, Nutella, Ritter, Knoppers, Toffifee and Haribo). Tony’s is backed by the Belgian investment group Verlinvest.












  • Europe is “dreaming” if it believes it can defend itself without US backing, Nato’s secretary-general has warned, pushing back against calls in some EU capitals to prepare for a future without Washington’s protection.

    The comments come after Donald Trump threatened to use military force to seize Greenland from Nato ally Denmark and to impose tariffs on other allies who opposed him — remarks that unsettled European governments and reignited debate over the continent’s reliance on the US. Although the US president rescinded the threats last week, they prompted renewed calls for Europe to accelerate efforts to strengthen its own defence capabilities.

    Mark Rutte, Nato’s secretary-general who last week persuaded Trump to withdraw his threats, dismissed those arguments on Monday. Rutte told EU lawmakers that building a fully independent European defence would be prohibitively expensive and would benefit only the bloc’s adversaries, including Russian President Vladimir Putin.

    “If anyone thinks here . . . that the European Union or Europe as a whole can defend itself without the US, keep on dreaming,” he said in remarks to the European parliament. “You can’t.”

    “I think there will be a lot of duplication and I wish you luck if you want to do it, because you have to find the men and women in uniform . . . on top of what is happening already,” he said. “It will make things more complicated. I think Putin will love it. So think again.”

    Independence from the US security umbrella that has shielded Europe since the second world war was once a niche idea, promoted largely by France.

    But the notion of “strategic autonomy” has moved steadily into the EU mainstream in recent years, as Donald Trump’s erratic approach to Nato allies — reinforced by Russia’s 2022 invasion of Ukraine — has sharpened debate over how Europe can strengthen its own defence capabilities.

    Last year Nato allies agreed to lift their defence spending to 5 per cent of GDP by 2035, responding to Trump’s demand that Europe shoulder a larger share of the burden for its own defence.

    Even so, experts warn that fully replacing the US role in Europe — particularly in areas such as advanced weaponry and critical capabilities on which European forces have relied for decades — would be vastly more expensive.

    “If you really want to go it alone, forget that you can ever get there with 5 per cent [defence spending]. It will be 10 per cent,” Rutte said on Monday. “You have to build up your own nuclear capability. That costs billions and billions of euros.”
