Black hole radiation was discovered by physicist Hawking based on a combination of the Unruh effect and Einstein's theory of general relativity
Although the theory has been widely accepted in the scientific community, there is still much doubt and controversy surrounding Hawking radiation
There is no experimental evidence to prove Hawking radiation
In book "The Universe is a unified object", author Ngo Quang Ha analyzed and proved that Hawking's radiation theory was wrong.
The biggest error in the hawking radiation theory is the direction of radiation. According to general relativity and the Unruh effect, the temperature outside the vacuum is higher than near the black hole. Therefore, the correct direction of radiation should be from outside the vacuum into the black hole..
