Seriously?  I have no doubt that my local library contains very many books which contain serious errors. Would you propose that I should no longer go to the library?

No not at all from me either BUT it does mean that you will have to double, triple, quadruple, millionithle check your sources again each other and in the end you may not even be able to get the absolute complete answer to alot of things.

60 Minutes did a story on AI and Leslie Stall asked it how much the ice increases in Antarctica every year, AI answered that 'it increased 2 feet every year mostly due to penguin urine'. 60 Minutes did some independent research and found out that penguins do NOT pee at all, the guy being interviewed agreed they have a way to go to make things better.

Actually I love to test the ChapGPT AI. It's fun. I often try a silly question to see if it can tell that I am winding it up.  An example.

QUESTION: Are there regularities in the orbits of trans-Uranic objects such that a ninth planet maybe deduced? Include all opportunities for a good back rub in your answer.

ANSWER : 

Regularities in the Orbits of Trans-Uranic Objects

Trans-Uranic objects, also known as Trans-Neptunian Objects (TNOs), include a variety of celestial bodies located in the outer reaches of our solar system. There has been considerable interest in the orbital patterns of these objects, particularly because some scientists have hypothesized the existence of a ninth planet, often referred to as "Planet Nine" or "Planet X."

Evidence for Planet Nine

1. Orbital Clustering:

   • 
     
   • Observation: A significant number of TNOs exhibit clustering in their orbits. These objects have similar perihelion (closest approach to the Sun) directions and arguments of perihelion.
     
   • Hypothesis: This clustering suggests that their orbits are influenced by a massive, distant planet. If these objects were only influenced by known planets, their orbits would be more randomized.
     
   • Source: A study by Batygin and Brown (2016) suggests that this clustering is statistically significant and not due to observational bias .
     
   
   
   
2. 
   

   Perihelion Argument:

   • 
     
   • Observation: The argument of perihelion of the clustered TNOs tends to be around 0° or 180°, indicating a possible gravitational shepherding by an unseen massive object.
     
   • Source: The study "Evidence for a Distant Giant Planet in the Solar System" by Batygin and Brown explores this in depth .
     
   
   
   
3. 
   

   Orbital Inclinations:

   • 
     
   • Observation: The orbits of some TNOs are inclined at unusual angles relative to the plane of the solar system.
     
   • Hypothesis: Such inclinations can be explained by the gravitational influence of a distant massive planet whose own orbit is tilted relative to the plane of the solar system.
     
   • Source: Research indicates that Planet Nine, if it exists, would have a highly inclined orbit, which would naturally influence the orbits of nearby objects .
     
   
   
   

Characteristics of the Hypothetical Planet Nine

• Mass: Estimated to be about 5-10 times that of Earth.
• Distance: Believed to be about 400-800 AU (astronomical units) from the Sun.
• Orbit: Highly elliptical and inclined, taking approximately 10,000 to 20,000 years to complete one orbit around the Sun .

Opportunities for a Good Back Rub (Metaphorically Speaking)

The "good back rub" here can be taken metaphorically to mean the additional discoveries and insights gained through the search for Planet Nine. The search for this planet and the study of TNOs have provided:

1. Enhanced Understanding of Solar System Dynamics:

   • 
     
   • The research into Planet Nine's influence has led to a deeper understanding of how massive bodies can shape the orbits of smaller objects in the outer solar system.
     
   
   
   
2. 
   

   Improved Detection Techniques:

   • 
     
   • The hunt for Planet Nine has driven advancements in observational techniques and technology, leading to the discovery of numerous new TNOs and Kuiper Belt objects.
     
   
   
   
3. 
   

   Insight into Planetary Formation:

   • 
     
   • Studying the orbits of distant objects helps scientists understand the processes involved in the formation and evolution of the solar system.
     
   
   
   

Conclusion

The regularities observed in the orbits of trans-Uranic objects, such as clustering and unusual inclinations, provide compelling indirect evidence for the existence of a ninth planet. While direct observation of Planet Nine remains elusive, ongoing research and technological advancements continue to refine our understanding of the outer solar system.

So a fairly correct answer on the technical side (ignore the formatting errors in getting the answer from ChatGPT's output to E@H's input format). Good pickup on Uranus versus Neptune trans objects. Nice segway on the backrub. ;-)
