In the morning, Voli asked Fein again about science.
'It's so early in the morning..." Fein couldn't help but sigh. He didn't expect his lazy friend would have such a geek hidden inside him.
Fein smiled at Voli's eagerness to learn and nodded, "Alright, let's talk about neuroscience and dimensions. You see, the human brain is one of the most complex structures in the known universe. It has over 100 billion neurons, and each one of them can have up to 10,000 connections. It's fascinating to think about how all of these neurons work together to create our thoughts, emotions, and actions."
Voli leaned forward, his eyes bright with curiosity, "What about the dimensions? How many are there?"
Fein chuckled, "That's a great question. According to the theory of relativity, there are four dimensions: length, width, height, and time. However, there are some theories that suggest there could be more. For example, string theory suggests that there could be up to 11 dimensions, but they are all curled up and hidden from our view."
Voli's eyes widened, "Eleven dimensions? That's incredible! How can we imagine that?"
Fein grinned, "It's not easy, but there are some ways to visualize it. For example, imagine a two-dimensional ant crawling on a piece of paper. To the ant, the paper is its entire world, and it can move in two dimensions: left and right, and up and down. However, if you were to lift the paper off the ground, the ant would suddenly be able to move in a third dimension: forward and backward. That's kind of how it works with higher dimensions."
Voli nodded, trying to wrap his head around the concept, "I think I understand. What about the fourth and fifth dimensions?"
Fein nodded, "The fourth dimension is often referred to as space-time, as it includes time as well as the three spatial dimensions. The fifth dimension is a little more difficult to explain, as it's often used in different ways by different scientists. Some theories suggest that it could be a way to explain the different states of matter, or even parallel universes."
Voli looked impressed, "Wow, science is amazing. I never knew there was so much to learn. But can you explain more?"
"No problem..." Fein's mouth twitched.
Fein took a deep breath before he started. "Neuroscience is a fascinating field, Voli," he said, looking at his young companion with a smile. "It's all about understanding the complex workings of the brain and how it affects behavior, perception, and consciousness."
Voli leaned forward, his eyes bright with curiosity. "Tell me more," he said eagerly.
Fein began by explaining the basic anatomy of the brain, describing the different regions and their functions. He talked about neurons, synapses, and neurotransmitters, and how they work together to create thoughts, feelings, and actions.
"As for the fourth and fifth dimensions," Fein continued, "they are theoretical constructs that mathematicians and physicists use to try and understand the universe. The fourth dimension is often described as time, but it's not just linear like we experience it in our everyday lives. It's more like a fabric, with events and moments woven together in a complex tapestry. The fifth dimension is even more abstract, and some theories suggest it might be related to the possibility of multiple universes."
Voli looked intrigued, but also a little overwhelmed. "That sounds really complicated," he said.
Fein chuckled. "It can be, but there are simpler ways to think about it. For example, think of a line. That's one dimension. If you add a second line perpendicular to the first, you create a two-dimensional plane. Add a third line perpendicular to both of those, and you get a three-dimensional space. The fourth dimension is like adding time to that, and the fifth is like adding more possibilities beyond our own universe."
Voli nodded slowly, digesting this information. "It's all so mind-bending," he said.
Fein grinned. "That's the beauty of science, Voli. It challenges us to think in new ways and expand our understanding of the world around us. And who knows, maybe someday you'll be the one making groundbreaking discoveries in neuroscience or theoretical physics."
Voli smiled back, his eyes shining with inspiration. "I hope so," he said. "Thanks for explaining all of this to me, Fein."
"Anytime, Voli," Fein replied warmly. "Science is a never-ending journey, and I'm always happy to have a fellow traveler along for the ride."
...
Fein, Voli, Aoi, and Sofia were standing at the shore of the island, looking out into the horizon. They had explored the island completely, but something didn't feel right.
Suddenly, the ground started shaking beneath their feet. It was as if the whole island was moving. They stumbled and tried to keep their balance, but it was impossible. Aoi fell to the ground, and Sofia grabbed onto Fein's arm for support.
"What the hell is happening?!" Voli shouted, panic in his voice.
Fein's eyes widened as he realized what was happening. "This island, it's not just an island. It's a pre-historic Kraken. It's alive."
The group was shocked and horrified. They had never encountered anything like this before. The ground continued to shake, and they could hear the Kraken's roars below their feet.
"Damn! An SS-rank peak energy spike! We need to leave, now!" Fein shouted.
He quickly grabbed onto Voli and Aoi's arms and teleported them away from the island. Sofia followed closely behind. As they materialized on the shore of a nearby island, they could still feel the Kraken's movements in the distance.
Everyone was breathing heavily, still in shock from what they had just experienced. Voli looked up at Fein, his face pale. "How... how did you know? How did you figure it out?"
Fein looked back at him, his expression serious. "It was the way the island was shaped. It didn't make sense for it to be a natural formation. And when we were exploring, I noticed strange markings on the rocks that seemed to match the patterns of a Kraken's tentacles. I should have realized it sooner."
Sofia placed a comforting hand on Fein's shoulder. "You did the best you could with the information you had. We're all safe now, thanks to you."
Voli nodded, still in shock. "I can't believe we were standing on a pre-historic Kraken this whole time."
Fein sighed. "We should have been more cautious. But we're safe now, and that's what matters."
The group sat in silence for a few moments, processing what they had just been through. Finally, Fein stood up and looked out into the distance. "We need to be more careful from now on. There's no telling what other dangers are out there. I didn't expect it to be SS-rank peak..."
"You can kill it right with your sword, right?" Sofia looked at Fein.
