So what is the Temperature of Black Hole. Is it hot or cold. The answer is hot and cold both. Lets find out how
Black Hole is Hot
When Black Hole pulls some with gravity the object is accelerated nearly speed of light. At speed of light particles will be having insane amount of kinetic energy. Thus due to kinetic energy of particles object becomes too much hot and temperature goes around millions of degrees.
Black Hole is Cold
Inside the Black Hole by calculations we found temperature in micro degrees just above the absolute zero. Near to singularity amount of mass is high. Due to density of mass particles are not having too much kinetic energy.
We can observe the hotness outside of the Black Hole. But can’t sense coldness inside the Black Hole.
Here is the more details on Black Hole.
