Artificial Star Systems, Galaxies and Universes | Summary and Q&A

TL;DR

Civilization may need to engineer stars, galaxies, and even universes to ensure survival and expansion in the future.

Key Insights

• 🤩 Natural star systems may not always meet the needs of advanced civilizations, prompting the creation of artificial stars.
• 🤩 Constructed stars exhibit unique characteristics, such as the absence of elements like helium, making them technosignatures.
• 🤩 Artificial galaxies and modified galaxies (red spirals) could indicate advanced civilizations strategically rearranging stars for their benefit.
• 👷 Artificial planets can be constructed by manipulating protoplanetary disks, but they require extensive time for habitability.

Nature currently has no shortage of stars, we live  in a time and indeed a galaxy where star formation   is ongoing and should we wish to to become  a kardashev type III galaxy spanning empire,   we will need to colonize a great many of those  stars. This is an easy task for the milky way,   the bulk of it is made up of suitable red  dwarfs that li... Read More

Questions & Answers

Q: Why would civilizations have a need to artificially engineer stars and galaxies?

Some regions in the galaxy are not favorable for life and colonization, so civilizations may need to create artificial stars and galaxies to ensure their survival and expansion.

Q: How can civilizations create artificial stars?

To build an artificial star, civilizations would need to collect large amounts of gas, particularly hydrogen, and allow it to collapse under gravity, initiating nuclear fusion and forming a functioning star.

Q: What might be the purpose of arranging stars in a specific pattern?

By using star movement devices like Shkadov thrusters, civilizations can arrange stars in beneficial configurations, creating interconnected colonies and facilitating communication and travel.

Q: How can civilizations construct artificial planets?

Civlizations can manage protoplanetary disks in young star systems to create tailor-made habitable planets. By adding or subtracting material at specific orbital resonances, civilizations can shape planet formation and potentially create a series of habitable planets in their star system.

Summary & Key Takeaways

• Creating artificial stars and galaxies may be necessary for civilizations living in areas of the galaxy with unfavorable conditions.

• Constructing artificial stars involves collecting vast amounts of gas and dust, mimicking the natural process of star formation.

• Civilization could arrange stars in advantageous patterns for communication and travel, potentially creating artificial galaxies. Likewise, they could modify existing galaxies to maximize habitable space by removing dangerous stars.
