Hi, I was searching for unsolved problems, and it showed like quantum gravity, etc. It also showed an "understanding of the nucleus" and "fusion energy." What do they mean by this? THow are they "unsolved?"
1. Understanding the Nucleus (Why It's Unsolved?)
We know that protons and neutrons stick together in the nucleus because of the strong nuclear force, but we don't fully understand all the details. Some mysteries include:
Why are some nuclei more stable than others? There are patterns in nuclear stability that we can't fully explain.
Why do some experiments give different results for neutron decay? This could mean there's something we don't understand about how particles behave.
How do nuclear forces really work? The strong force is incredibly complicated, and we can't perfectly predict nuclear interactions.
2. Fusion Energy (Why It's Hard?)
Fusion is what powers the Sun—it's when small atoms combine to make bigger ones, releasing huge amounts of energy. Scientists want to use this for clean energy, but there are big problems:
It takes extreme heat (100 million °C) to start fusion. Keeping that heat inside a reactor is really difficult.
We haven't made it efficient yet. So far, we use more energy to start fusion than we get out.
The reactor materials break down. The extreme conditions wear out the walls of the reactor, so we need materials that can survive.
Scientists are working on both problems, and solving them could change our understanding of physics and energy! 🚀
ohhh! I see. I was thinking of something else; thank you!
