Can Black Holes Be Destroyed?

Introduction

• Black holes can destroy everything.
• Question: Can they be destroyed?
• Hypothetical scenario: Creating a tiny black hole in the Kurzgesagt Labs.

Nuke It

• Exploding a nuclear arsenal around the black hole.
  • Black holes swallow matter and energy, increasing in mass.
  • As per E=mc², energy entering a black hole increases its mass.
  • Nuking it only makes it more massive.

Antimatter

• Throwing antimatter at a black hole.
  • Matter and antimatter annihilate each other.
  • Black holes delete past identity, only care about total mass-energy.
  • Antiparticles have the same mass as particles; results in increased mass.

Elementary Particles Analogy

• Black holes are similar to elementary particles (specified by mass, spin, and charge).
• Regardless of origin, black holes are described by these three numbers.

Anti Black Hole

• Hypothetical: A black hole with opposite charge.
  • Colliding black hole with anti-black hole cancels out charges, resulting in a more massive black hole.

Destroy the Event Horizon

• Over-spinning or overcharging a black hole.
  • Exceeding limits can dissolve the event horizon, exposing the singularity.
  • Singularities are points of infinite gravity and spacetime distortion.
  • Removing the event horizon stops objects from being trapped forever.

Overfeeding

• Attempt to overfeed black hole with small mass objects having high charge/spin.
  • Electrostatic repulsion or spin limits prevent overfeeding.
  • Possible loophole if done precisely at upper limits.

Breaking Physics

• Removing the event horizon creates a "naked singularity."

Singularity's future position creates a problem as it disrupts predictability and causality.

• Naked singularities could lead to unpredictable outcomes and breakdown of physics.

The Safe Option: Hawking Radiation

• Hawking radiation causes black holes to slowly lose mass and evaporate.
  • Small black holes would take extremely long to evaporate (e.g., 10^44 years for a moon-mass black hole).

Conclusion

• Technically possible to destroy black holes by waiting for Hawking radiation.
