For reference, without AXIS, the earliest that a high-resolution X-ray imaging mission can launch -- the successor to the Chandra X-ray Observatory -- is 2050s or 2060s. ๐Ÿ”ญ

๐Ÿ‚ 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!

Det รคr lite samma koncept som robotarna TARS och CASE (och KIPP, fast han รคr dรถd) frรฅn Interstellar.
I deras grundform รคr 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

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.

๐Ÿงต 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.
