What Happens If You Destroy A Black Hole?
Kurzgesagt – In a Nutshell・2 minutes read
Black holes can grow by absorbing matter and energy, with matter and antimatter having the same effect on increasing their mass. Destroying a black hole can be achieved through various means such as overfeeding it or waiting for it to emit Hawking radiation and evaporate over billions of years.
Insights
- Black holes can grow by absorbing matter and energy, following E=mc^2, which increases their mass.
- Destroying a black hole's event horizon might release objects from its gravitational pull, but the singularity's location in the future makes interactions unpredictable.

Recent questions
How do black holes grow in mass?
Black holes grow in mass by absorbing matter and energy, following the principle of E=mc^2. This absorption leads to their increase in size and gravitational pull.
What are the main characteristics of black holes?
Black holes are described by three main characteristics: mass, spin, and charge, similar to elementary particles. These properties define the behavior and interactions of black holes in the universe.
Can black holes be destroyed?
Theoretically, overfeeding a black hole with charge or spin could potentially lead to its destruction, although this remains a topic of debate among physicists. Another method is to wait for the black hole to emit Hawking radiation and evaporate, a process that could take billions of years.
Where is the singularity of a black hole located?
The singularity of a black hole is not at its center but in the future, making it impossible to predict interactions with it. This mysterious aspect of black holes adds to their enigmatic nature in the cosmos.
What happens when a black hole absorbs antimatter?
Matter and antimatter have the same effect on black holes, increasing their mass when absorbed. This process contributes to the growth and evolution of black holes in the universe.
