B How would physics change if Planet 9 were a primordial black hole?

AI Thread Summary
The discussion centers on the speculation that Planet 9 could be a primordial black hole, as suggested by futurist John Michael Godier in a YouTube video. He proposes that if such a black hole were accessible, it could serve as a unique laboratory for testing physics beyond current capabilities. However, participants express skepticism about the feasibility and relevance of this idea, noting the lack of evidence and concrete examples provided in the video. The conversation ultimately concludes that the topic is largely idle speculation and not worth further exploration without substantial evidence. The thread is closed due to these concerns.

TL;DR Summary
I am speculating on how an accessible black hole could be used for physics
I watch John Michael Godier on YouTube. He is a futurist and makes fantastic videos where he speculates on many things. Todays video was about primordial black holes and he speculated about Planet 9 not being visible because it may actually be a black hole born in the dawn of the universe. He admits it’s a long shot but also said that if we did have an accessible black hole that we could turn it into to a lab to test physics we currently can’t do right now.

He maddeningly did not give an example and the video ended. What kinda of science experiments could be done with a black hole?

How useful would be an undetectable object that probably doesn't exist but in any event we can't get to? That's a toughie.

So it's idle speculation and hardly worth our time to discuss. We normally require some evidence .

... and given the fact that youtube isn't a source of reference we mean by evidence,
this thread is closed.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
