All the actual normal material in the universe bunched up to a single ball of matter, how big would the ball be?
Never mind whether it'd fall in on itself. Just imagine a broom sweeping it all together. How big?

I'm not sure if this is criminal or just inadvisable.

"Satellites associated with the Starshield satellite network appear to be transmitting to the Earth's surface on frequencies normally used for doing the exact opposite: sending commands from Earth to satellites in space. The use of those frequencies to "downlink" data runs counter to standards set by the International Telecommunication Union, a United Nations agency that seeks to coordinate the use of radio spectrum globally."

🌗 週日晉升，週一解僱：NASA辦公室突然關閉的內幕
➤ NASA的科學諮詢機構遭裁撤，引發大規模人才流失與對未來任務的隱憂
✤ www.planetary.org/a...
本文深入報導了NASA首席科學家辦公室（OCS）突然關閉及其引發的大規模員工離職事件。OCS原為NASA提供獨立的科學諮詢，然而在2025年3月，該辦公室及其員工遭裁撤，導致約4,000名NASA員工，超過兩成的專業人才離開，其中包括經驗豐富的領導層和專家。這種不明原因的人事變動，不僅打擊了NASA士氣，也引發了對國家太空探索能力和科學任務安全性的擔憂，特別是在政府強調科學誠信的同時，此舉顯得諷刺。文章透過兩位當事人的視角，揭示了決策的倉促與影響的深遠。
+ 這真是太令人震驚了！OCS的存在對NASA的科學決策至關重要，他們的關閉以及員工的離職，對NASA的未來發展無疑是個巨大的打擊

It is up to Bluesky's owners to decide if they want to be hosting wholesale violations of the Hatch Act along with other blatant lies by those with Donald Trump.

But everyone else should block every one of the offending accounts.
