 The difference is that when you have a lot of gas, a lot of stuff orbiting around the black hole, there is a little bit of friction¹ that causes matter to slowly spiral in towards the black hole. 

 

As gas continues to spiral in towards the Event Horizon, gravity climbs to staggering extremes. Gas molecules² are forced into a whirlpool as they queue up to be devoured³ by the black hole. Friction between gas particles and this cosmic waiting line produces the densest⁵, hottest, most electrically charged environment to be found anywhere in the universe. 

 

Friction between different parts of the gas caused it to heat up and it's very much like when the Apollo Rockets return to the earth and travel through the earth's atmosphere. As they plough through the earth's atmosphere, they heat up because of the friction between the satellite and the atmosphere of the earth. What we know is that the harder something gets, the brighter it gets, the more light it emits. 

 

Under the intense gravitational fields at the entrance to the black hole, the dense⁴ superheated disk of matter waiting to be swallowed begins to shine like a sun, but a sun like no other.
