８４　Hawking Radiation　２【Black Hole】Dialogue with the Universe

・One of the characteristics of the quantum theory is that there is no empty space thing.
・This may look empty at first glance, in a micro scale pair production of virtual particles of negative energy and positive energy always has been done.
・Positive-energy particles can escape from the black hole if energy is greater.
・On the other hand, negative energy particles are sucked into the black hole.
• Since the negative energy particles are inhaled, the energy of the black hole is reduced as a result, the black hole becomes smaller gradually.
・Black hole is going to "evaporation". 
・However, the time to partition evaporation is 105.9 billion years, that is orders of magnitude longer than the age of the universe about 14 billion years.
