Theory of the Stars*

The Sun: This is what the sun looks like (with glare protection,
probably).

     Most people know that the sun was born 4.57 billion years ago. But what I was thinking was, about an important property of light, that actually might make the birth of the sun a few million years back. But before I explain my theory, I have to explain how the sun was born.

 

     When a star dies, usually what happens is that stars start to shed it's outer layers. For many years, scientists didn't know why. Then, a person named Emanuel Swedenborg first proposed a theory that stars were formed by nebula's in space. You probably want to know what a nebula is. Well, it's when a large mass of atoms form a cloud in interstellar space. One of the most distinguishing facts about nebula's is that they are created by the death throes of a dying star.

 

    When a star starts dying, it means that the core of the star has started to make iron. But how does a flaming mass of hydrogen create an element like iron? Well, here's how.

First, when the star is born, it immediately starts fusing together hydrogen to make helium. The reason it does this immediately is sort of part of my theory. When the star gives out light, it means that it is fusing hydrogen together to make helium. But we don't know it's ready until it gives out light, don't we? Well, anyways, the heat forces repelling hydrogen atoms to fuse to helium. Helium's mass is less that it should be because some of the mass is converted into energy, some of it as, light, the rest, heat. This small observation is crucial to why a star dies at a certain element. Anyways, this process isn't supposed to get past helium, because we still have enough hydrogen. But what happens when we run out?

The Process of Fusion

    Fusion is the universe's true power. It is what drives stars. Fission, splitting atoms, releases only so much energy. But fusion is so powerful, a kilometer of seawater can equal the worlds' oil reserves (in terms of energy). If only we can master this powerful force. But there is a possibility. And the possibility is called HiPER.

    HiPER stands for European High Power laser Energy Research facility. This ambitious group of people think lasers are the way to go in order to master the power of fusion. There are other ways, but they are focused on this one. They have a plan too. But first, let's take a look at the energy problems were facing.

    People predict that between 2000 and 2030, the global energy demand will go up by 70%. This means that we will need a generating capacity (for the world) of 5,800 gigabytes. That's five times the present energy capacity of the United States. They say that only laser fusion can stop this demand for energy. It is expensive, but it will reap benefits that greatly overwhelm the expense. 

    But what is this "plan?" How does it work? Will it work? They haven't tested it yet, but they will try. And now, I will show you the plan. 

    Since it is a little hard to explain, I will show you in this video.

Time Travel 2

    As you saw in my first time travel blog, (Time Travel: Into the Future, and Time Travel: Into the Past) there were two separate things that I had to do in order to time travel both into the future, and into the past. However, there is a better solution to this, that can use the same (or almost the same) way to time travel. It involves superfluids, speeds of light, and of course, time travel. Keep on reading in order to see what this solution is.

 

    First, lets think of a normal fictional time travel machine. You just get into the machine, press a few dials, and zip! Your there. However, the reality is much different. We can't actually tame time and force it to flow backwards for everybody. However, we can go through it. The reason why is that space and time are interconnected, in something called space-time. This was predicted in Einstein's theory of general relativity. I think this is one of the reasons that we experience time. But there's more. As gravity is produced by warping space-time with large bodies, and since space and time is interconnected, Einstein came to the conclusion that the larger the body, the more space, and time, is warped.*

Hypervelocty Stars: What are They?

In our galaxy, there are millions of millions of stars. Since our galaxy is a spiral galaxy, the spirals are spinning. That means our star, and every star, is moving very, very, fast, up to a million miles per hour. But not relative to each other. But there is a class of stars that are moving the same speed, but in a very different way. They are called "Hypervelocity Stars".

 

    What are they? You may ask. Well, they are stars that can travel up to a million miles per hour. That seems normal because normal stars are traveling the same speed. But that speed is not relative. So compared to other stars, hypervelocity stars are moving a million more miles an hour. That's 0.2% of the speed of light! But how can these hypervelocity stars move that fast?

 

    Since stars move at a million miles per hour, and since their should be tiny differences, shouldn't the faster ones be the hypervelocity stars? The answer is no. The reason is that most velocities (except the speed of light) add up. So the stars can't be the faster ones in a spiral galaxy. Also there is another problem. Stars like these come like, once in every ten thousand years. I don't think that there is a means to propel a star a million more miles per hour in a spiral arm. So we need another theory. But what other reason could they're be for a hypervelocity star?
