Hitching a ride on an extrasolar object – Take lots of supplies and plan for 10000 years

Hitching a ride on an extrasolar object – Take lots of supplies and plan for 10000 years — I was working out what is needed to image nearby stars and planets. But I remembered that Oumuamua extrasolar object.   https://en.wikipedia.org/wiki/Heliosphere#Heliopause   If another one passes by, or there was some way to catch up, Elon

Humans can colonize Milky Way Galaxy through intelligent devices, and search for gravity signals

Humans can colonize Milky Way Galaxy with intelligent devices, and search for gravity signals. — Galactic civilizations using intelligent devices can live billions of years. So the most likely “species” for human devices to meet would be intelligent devices. Nancy Grace Roman Space Telescope might look for intelligent messages in the galactic plane. And space

Most species in the Universe might be fabricated, not natural, and live for Millions of years

Watching “Are We Alone?” at https://youtu.be/c53yK1MJOY, I thought (Most species in the Universe might be fabricated, not natural, and live for Millions of years)  If fabricated lifeforms are the dominant species, even from organic precursor species – once formed they can spread for billions of years. Have unique memories and existence for millions/ billions of

Compiling and resolving dependencies for all pages on the Internet

Richard Collins: Can you tell me details of the Atacama Total Power Array? It seems to be four (12 meter) radio telescopes. Is any of the data available from the Total Power Array available? I am reading “Discovery of an Accretion Streamer and a Slow Wide-angle Outflow around FU Orionis” at https://iopscience.iop.org/article/10.3847/1538-4357/ad31a1 and want to

Most repositories on software sharing sites are badly structured

I am reading the 14 repositories for CASA (Common Astronomy Software Applications) at https://github.com/orgs/casangi/repositories   There are only 6942 files and 1814 folders in total and what appears to be many duplicates. And MANY duplicate file and folder names. A good part of the problem with CASA is the poor methods for file management. If
