Investigation of UFOs - Taylor K.
With this paper, I only used one source to find my information. Because this book was so helpful, I found a lot of solid information and it was really easy. This research project was probably my favorite because it is fun to think about the existence of UFOs.

Life on Other Planets~ Amanda D.
Life On Other Planets

Researching for this project I found to be slightly hard, but not really all that bad. What I found very interesting is how communication between planets is a big problem. We could receive a message from a galaxy or planet in millions of years and it could of been sent today. The vastness of space is just so fascinating that is sometimes very hard to fathom.

Find information for the subjects of dark matter and dark energy was challenging. It was difficult because a lot of the websites were unclear about exactly what they are. Also, none of the sites seemed to agree on the percentage of matter and energy that is dark. I was unable to find information about the idea of dark matter and energy being used as an energy source. The most interesting fact that I discovered, was that a lot of the energy in the universe is dark.

I thought this topic of research was very interesting. The facts that I found were fascinating and the one that suprised me -- or made me the most interested -- was that dark matter and dark energy, together, make up almost 95% of our Universe! This project was not extremely difficult to find information on, but because it is not a proven fact that these materials exist, some facts were not fully proven.
Was the First Moon Landing a Conspiracy?
Researching the first moon landing conspiracy idea was pretty easy. There were many good websites on it, and I liked seeing what people noticed about it. I thought it was interesting that they saw that the flag was waving and that there were no stars visible.

Conspiracy on the Moon - Karen Y
I found this research easier than the rest since you could just pick a side and then find all the information you needed. This time there were only two sides to pick from, so it wasn't as complicated. I found the fact that many people thought the footprints were just wet sand very interesting because it shows that not many people are willing to do their research.
Black Holes - Karen Y
I thought that this was a more difficult topic to research since we don't know for sure a lot of information about black holes. Once I decided that I wanted to narrow in on the singularites, it was easier to find information. I thought the most interesting fact was that there may be naked singularities out in the universe somewhere.

Black Holes -- Ryan Franda
Black holes are possibly one of the most confusing astronomical occurrences that I’ve heard of. I’m going to try to explain what they are, what goes on inside them, what we don’t know and what we theorize to be true.
A star is constantly in balance between atomic explosions pushing outward and gravity pushing inward. This makes the sun a large ball of fire, but it still keeps it from exploding or imploding. Black holes are formed after a star’s atomic power runs out. In other words, it runs out of gas. This disrupts the balance, and in a regular-sized star the gravity just makes the star compact, and turn into a white dwarf, and eventually, a black dwarf. In a star of unusual size, however, the gravity is suddenly released with nothing to fight against it. This causes it resort to a complete spasm – a supernova. This is a huge explosion that resounds through space, leaving in its path, a black hole.
Black holes have incredible gravity. They are not, however, like a vacuum cleaner. They act like any other body – a star of planet – of great gravity. However, when they are close to something, they pull it towards it and suck it into its center, because they have such large gravity. Why do they have so much gravity? As you near a black hole, and start to get pulled in, you become more and more at the mercy of the black hole. When you travel past a certain point, called the event horizen, you would have to travel past the speed of light to escape. Eventually you get pulled right into the center of the black hole. This is only a small point, with mass getting compressed to an extremely tight and hot ball, called the point of singularity. The matter here is so tight tight, some even say it is infinitly dense.
Actually, nobody knows what goes on at the center. It is true that some theorists suggest infinite density, but for that to happen, there would need to be a volume of zero and infinite gravity, and for a lot of people that is hard to comprehend. It is possible that there is simply extremely high gravity and density in the center. I think this is more likely, because with infinite density and gravity the gravitational pull would be so great that it would take in everything near it, and thus provide more fuel until it eats the universe itself. It is hard to find out exactly what is at the center, because they suck in light, but with special cameras that track different rays than light rays, we can learn more about what is there.

I found that it wasa really hard to figure out theories about the center of a black whole. Infinite density is just impossible to wrap my mind around...

Allie H.--Dark Energy and Dark Matter
A piece of information that I found interesting was 99.9% of matter in the universe is dark matter, therefore 99.9% of all matter in the universe is partially a mystery. Most of this research was easy, but the only thing I couldn't find anything on was some implications on whether or not we could store dark matter or energy.
