Why are Boltzmann Brains considered a problem for physics?

[TheQuestionGuy14]

When Boltzmann brains are mentioned in physics, they're often seen as a problem. An idea that is forbidden. Physicists like Sean Carroll actively tried to come up with new theories that avoid Boltzmann brains. Others like Leonard Susskind have also labled them as problems. Why is this, what's so wrong with them? Are physicists worried about the idea that we ourselves are Boltzmann brains?

 

[Andrew Mason]

They are not a problem in physics. If they are a problem it is a problem for philosophy not science.
