Cosmology* » External pressure*
A stronger external pressure is directed to the black hole than to the other orbs.
This is because the massive and a little external surface possessive energybundles opening up from the black hole don´t have interaction with the expanding energybundles that pass by the black hole.
Now the expanding energybundles passing by the black hole push each other towards the black hole with the energywaves opening up from themselves. This is why more three-dimentionally expanding energybundles go towards the black hole.
They also move their kinetic energy more towards the pieces that locate nearby the black hole than the energybundles opening up from the black hole can move their kinetic energy towards the pieces close to the black hole.
The large energic energybundles coming from the black hole pull with them the energywaves coming from the energybundles that across them. The energybundles acrossing open up energywaves which burn out because of the energywaves opening up from the large energic energybundles and are then pulled with them away from the black hole.
Now the expanding energybundles that go towards the black hole don´t push themselves away from each other.The energywaves opening up from them are cleaned away and this way they can not make each other to explode energy towards each other with these energywaves. The continue their expanding and reach out for each other, without moving towards each other. The cold fusion is in question.
This is how a bigger external pressure is directed to the black hole.
