A satellite re-entering every 3 minutes. Seems fine.

Satellite proposals threaten the night sky In the United States, the Federal Communications Commission (FCC), the agency responsible for authorizing satellite launches and operations…

The FCC just opened public comments on SpaceX's plan to launch a million satellites to do AI compute in space. Under the current proposal, an environmental review won't be required. Please consider submitting a public comment to oppose this damaging plan.

🍂 What if a black hole born from the merger of two black holes merged with another black hole? We may find out thanks to gravitational waves, such as those observed by the @ligo.org - Virgo - KAGRA Collaboration in autumn 2024. Let's learn about these signals!

Jo, det är klart.
I filmen är de återvunna militärrobotar, så hållbarhet var nog prioritet över finlir.

Det kan vi inte veta 😉
Men jag tror att man bara ser fyra-fem delningar i filmen.

YouTube Share your videos with friends, family, and the world

Det är lite samma koncept som robotarna TARS och CASE (och KIPP, fast han är död) från Interstellar.
I deras grundform är de ju "bara" block, men de kan splitta upp sig i mindre och mer finmotoriska delar.

My doomer-worry about AI is not that the LLMs become omnipotent and take over the world but that the wealthy and powerful use it as a means to consolidate power and marginalize or lay off skilled workers and also everything about our technological and political and social life gets worse

The money does not go into space. The money does not go into space.
The money does not go into space.

Sure, the money helps us in exploring and understanding the universe, but the money actually goes to people, to local economies, to universities, it provides jobs, and gets young people into STEM.

A few months ago they let me walk around the Goldstone Deep Space Communications Complex at night. Don't know if it was the desert rain, watching skyscraper-sized antennas swivel to catch signals from beyond Saturn, or just my fillings buzzing from the radio signals, but I had goosebumps all night.

🧵 NSF is reducing external review requirements and eliminating routine expert panels, citing staff shortages that this administration implemented. This change expands program officer authority. But the solution to flawed accountability isn't less public accountability.

Nu räcker inte ögat längre När AI får oss att inte lita på något längre, då utmanas demokratin.

Återigen har @myrannosaurus.doomscroll.se skrivit dagens viktigaste text (om AI):

"Istället för att fokusera på lösningar för att peka ut vad som lurar människor behöver vi framtidssäkra för en befolkning som inte vågar tro på någonting alls. Som inte går att övertyga, ens med riktiga bevis." >

True!
Hence, my second favourite black hole is the less massive component of GW241011!
