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

Click For Summary

Discussion Overview

The discussion revolves around the speculative idea of Planet 9 potentially being a primordial black hole and the implications of such a scenario for physics experiments. Participants explore the feasibility and scientific value of conducting experiments with a black hole, as well as the nature of evidence required for such discussions.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant references a YouTube video speculating that Planet 9 could be a primordial black hole and suggests that it could serve as a unique laboratory for physics experiments.
  • Another participant questions the usefulness of discussing an undetectable object that may not exist and expresses skepticism about the value of such speculation.
  • A third participant summarizes the discussion as idle speculation, emphasizing the need for evidence in scientific discourse.
  • A later reply reiterates the point about the lack of evidence and suggests that discussions based on YouTube content may not be substantial.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the value of the speculation about Planet 9 as a primordial black hole, with some finding it unworthy of discussion due to the lack of evidence and others interested in the theoretical implications.

Contextual Notes

Participants highlight the absence of concrete evidence and the speculative nature of the claims made in the YouTube video, which may limit the discussion's depth and relevance.

Who May Find This Useful

Individuals interested in theoretical physics, black hole research, and speculative astrophysics may find this discussion relevant.

TL;DR
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.
