White holes create space and matter, and Black holes took them away. Together, the two phenomena kept an equilibrium on the amount of energy that existed in a galaxy at every time.
White holes only appeared once towards the start of the universe formation when galaxies were already starting to form.
The White holes spewed out as much matter and space as they could and then went dormant. The galaxy at that moment would be in equilibrium that nothing could disturb. After that, the galaxy would go on to create billions of stars and planets.
And then, the problem would arise when the planets would start creating life, and along with them create an Origin of their own.
Now there was more energy in the Galaxy than the galaxy could possibly handle. In such conditions, the galaxy would fester until it was ripe with a lot of energy.
When the dormant White hole noticed the excess amount of energy, it would go active again, however this time, instead of sending out matter and space, it would start dragging it in.
The portal to the dimension of Energy would open with a strong gravitational pull of its own to drag things towards it. Once enough matter had been dragged, it would form an accretion disk, and become the Blackhole everyone came to recognize it as.
This wasn't the only way black holes were created. When there was a massive star, there would sometimes be so much heat and pressure at its core that the space there would slowly become fragile.
Then, when the star lost the heat and pressure, the fragile space would tear itself, inadvertently opening a portal back to the dimension of Energy, more time than not.
As such, more black holes would come to exist in the world that had way too much energy, leeching it all back. Once that started, the black holes would never end until the day the universe died.
Ning stood by the window with a thoughtful look on his face, learning something he would've never expected to learn.
"So wait, what happens if I ever accidentally fall into a black hole? Is it instant death?" Ning asked.
"Oh," Ning said. "So it is not instant death, huh?"
"Good… that's good to hear," he thought. There was a lot in his head at the moment. Even as the ship came close to the wormhole, his mind still remained on the black hole below him.
"Wait, so black holes don't have energy aside from the gravitation pull right?" Ning asked.
"Then when you said in regards to how much energy I need to travel the multiverse, that was…"
Ning thought to himself for a moment. "Wait, then doesn't that mean it is way cheaper than I thought?" he asked.
The ship got closer to the wormhole and Ning let the AI handle everything. Ning just stood there, looking at the brilliant nothingness below him.
Then, after a few minutes, they all passed through the wormhole, undergoing a bit of turbulence, before coming out on the other side unharmed.
Once they were on the other side, the spaceship moved away from the wormhole and flew out.
Now that Ning was finally not able to see the black hole anymore felt the lack of fear in his heart. He thought of what else to do next when he remembered something.
"Oh, right," he thought.
"System, the next energy costs 1 Quintillion, right?" he asked.
"Alright, buy it," Ning said.

"I should find some places with strong gravity," Ning thought to himself. He thought of a location and asked the system for direction.
Ning realized that there was one close by, so once again, Ning took his spaceship and flew in the direction of the closest Service Station in the Federation.
When he arrived close by about 2 years later, he put away Saphandra and the Ship and teleported right next to it.
Ning needed more Space stones, and this was the way to get it. But aside from that, the Service station was also close to a bright sun that not only would provide him with the gravitational energy he required, but would also make his physical body stronger.
Ning had about 18 years before he had to arrive at the location where the two universes would come to be the closest.
Since that was less than 25 light years away, Ning could travel that distance with just a small piece of Space stone.
Ning flew right next to the sun where his skin started blistering and floated there, orbiting the bright star as well as he could without being noticed by the federation.
And he did so for the next 17 and a half years.
