Read and understand · 1/2What was the method?

Read the answer and explanation

Calculations. This was theoretical work.

Clue: Physicists have investigated black-hole fragmentation in a Physical Review D paper published on October 22 and presented by SDU on October 23. The work analyses theoretical constraints rather than reporting a detected event.

Read and understand · 2/2What must fragments do?

Read the answer and explanation

Separate. They must move apart.

Clue: Thermodynamic rules prohibit ordinary non-rotating black holes from splitting. Near-maximal rotation may offer a limited exception, but requiring the fragments to separate imposes additional restrictions. Mathematical permission alone does not establish that fragmentation actually occurs.

Your turn

Explain the finding and its limit.

See one possible answer

Theoretical possibilities do not establish an observed split.

Your answer can be different. Give a reason and use your own words.
