Blanets and Forsaken Worlds

TL;DR

The universe is filled with planets so drastically different from our own that no one would dare to visit; from carbon worlds to strange matter planets and planets orbiting black holes.

Transcript

On this channel I often talk about habitable zones and exoplanets that might be something close to earth, or even nearly identical to it. While this is eminently possible in the universe, even probable, and we’ll no doubt soon discover candidates for such worlds, there are also planets in the universe that we will probably never go near, even if we...

Key Insights

• 🥳 Carbon worlds have high carbon-to-oxygen ratios and lack water, but may contain unique geological formations like graphite and diamond deposits.
• 🤩 Strange matter planets form in the extreme gravitational fields of neutron stars and are highly dangerous, instantly converting normal matter into strange matter.
• 🙂 Planets in close orbit around black holes, known as blanets, face extreme radiation but could potentially receive light from the cosmic microwave background radiation.

Questions & Answers

Q: What are carbon worlds and why are they considered inhospitable?

Carbon worlds have high ratios of carbon to oxygen, resulting in a lack of water. This affects the geology of these planets, leading to unique formations such as graphite and diamond deposits. Their extreme conditions make them inhospitable for life as we know it.

Q: Are there any known examples of carbon worlds?

While no confirmed carbon worlds have been discovered, there are indications that they exist. The exoplanet 55 Cancri E shows a high carbon ratio and may be one of these unique worlds.

Q: What are strange matter planets?

Strange matter planets are hypothetical planets formed in the extreme gravitational fields of neutron stars. They contain stable strange matter, which is poisonous to normal matter and can rapidly convert it into strange matter. These planets would be highly dangerous and uninhabitable.

Q: Can planets orbit black holes be habitable?

In theory, planets in close orbit around a black hole could receive concentrated light from the cosmic microwave background radiation, creating a sun-like source. However, the conditions near a black hole, including intense radiation and extreme gravitational forces, make it highly unlikely for these planets to support life.

Summary & Key Takeaways

• There are planets in the universe that are so radically different from Earth that they are essentially uninhabitable.

• Carbon worlds, with high carbon-to-oxygen ratios, lack water and have unique geology, potentially featuring graphite and diamond deposits.

• Strange matter planets, formed in the intense gravitational fields of neutron stars, would convert any normal matter they come into contact with into strange matter.

• Planets in close orbit around black holes, called "blanets," face extreme radiation and harsh conditions, but could potentially receive light from the cosmic microwave background radiation.
