There are several theories as to how the universe came about, and the most heard of is the “Big Bang Theory”. According to this theory the world isn't infinite but definite. There was a definite beginning and will be a definite end. "The beginning started with a huge explosion that extended the universe into what it is today". It is not known what existed before this explosion, but is thought that the explosion contained all the energy in the universe. The name "Big Bang" was given to this theory by Fred Hoyle in 1964. He tried to make fun of the theory by calling it this but the name stuck, which i guess is still funny and ironic.

Of course religion has a different perspective. They believe that God decided to just make a universe and then here we are. Religions do not question the exactness of how we all came about, they just believe that God created the universe and let the bible take over from that point, which doesn't make a lot of sense, how are people supposed to just believe that something just happens without hard evidence.

Another newer theory is called the "Intelligent Design", which is an awkward mix of religious views and the big bang. It says that God created it, then evolution and natural selection formed us into what is existing today. This theory seems a little bit more believable but not the hard evidence that most people want, but it makes most people happy to think about this.

I think that people are aloud to believe what they want to believe. If it really gives people false hope that there is an almighty being that said let there be an existence then far be it from me to call them wrong. And if a bunch of geeks think that something called "evolution" and a "big bang" occurred and that's why we're here today, let them write a few more books on it and maybe if they really really try, i might believe their answer. I personally think that we're a germ on some other huge specimen, it makes sense right? What ever anyone thinks they should just know their wrong. There is no way that anyone can ever know exactly where we came from.

Solar Systems and Galaxies

A galaxy is any of numerous large-scale aggregates of stars, gas, and dust that constitute the universe, containing an average of 100 billion solar masses. They are ranging in diameter from 1,500 to 300,000 light-years. this is also called "nebula". Ours galaxy is called the "milky-way" galaxy, which i might add is a very delicious candy bar if anyone hasn't tried it. It includes many stars and other planets. A galaxy is much bigger than a solar system, a galaxy includes more that just our planets and the sun.

A solar system is a "system of planets or other bodies orbiting another star", from answers.com. The Sun and the bodies moving in orbit around it. The most massive body in the solar system is the Sun. There are eight planets in our solar system. Here is a list of them from increasing average distance from the sun, Mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Every planet in our solar system revolves around the sun, each planet has its own moon or set of moons. Pluto was recently decided on as being "not a planet", it has no moons.

They are alike because they both house all of us, humans and animals. A Galaxy is far bigger than a solar system because there are many solar systems in one galaxy. I don't really have an opinion on this subject because yeah space is cool and everything, but it's way to big. There is no way that the human race will ever be able to map out or even come close to finding out what even a tenth of our galaxy is like. Yeah we can look through a telescope, but we'll never ever go anywhere. I can only hope that an alien race one day will show us a way to go to the ends of the universe.

There are a lot of astronomers that think that a star begins as a dense cloud of gas in the arms of spiral galaxies. Individual hydrogen atoms fall with highly increasing speed and power or "enery" toward the center of the cloud under the force of the star's gravity. This increase in energy heats the gas. When this process has continued for a few million years, the temperature reaches about 20 million degree fahrenheit. At this temperature, the hydrogen within the star lights on fire and burns in a continuing series of nuclear reactions. The onset of these reactions marks the birth of a star.



Red giants have diameter's between 10 and 100 times that of the Sun. They are very bright because they are so large, although their surface temperature is lower than that of the Sun. A White Dwarf is a very small, hot star, the last stage in the life cycle of a star like our Sun. White dwarfs have a mass similar to that of the Sun, about the size of the earth, which is 1% our sun. The surface temperature of a white dwarf is 8000C or more.


A star is a luminous globe of gas producing its own heat and light by nuclear reactions. The brightest stars have masses 100 times that of the Sun and emit as much light as millions of Suns. A Red Giant is a large bright star with a cool surface. It is formed during the later stages of the evolution of a star like the Sun, as it runs out of hydrogen fuel at its centre. Red giants have diameter's between 10 and 100 times that of the Sun. They are very bright because they are so large, although their surface temperature is lower than that of the Sun.

I don't really have an opinion on anything like this. The closest star near us is our sun and that looks like its still in its pubesent years, so no fears then. I'll be worried when our sun starts to look a little different in the size and color area or when scientists say something. Until then, I'm not going to worry about anything silly like a black hole sucking me up.

The term "science" is defined as "the investigation of natural phenomena through observation, theoretical explanation, and experimentation, or the knowledge produced by such investigation" by The American Heritage Science Dictionary. Science is a reference of a system that acquires knowledge based on observations, scientific method. There are two common classifications of science, natural science and social science. Natural science is a study natural things such as biology. Social Sciences are studies of societies and homosapiens behavior. Science must be able to be replicated by anyone and get the same results.

Pseudoscience may have a lot of the same characteristics of science, but is different in many ways. Examles of pseudoscience are palm reading, horoscopes, and the weather, ha ha just kidding. Pseudoscience is used for one's own ego or to gain support, theres not always a scientific method behind it. The term "pseudoscience" is defined as "a body of knowledge, methodology, belief, or practice that is claimed to be scientific or made to appear scientific, but does not adhere to the scientific method", by wikipedia.com. People just accept pseudoscience (examples above), nobody really tests the theory behind it. A "lack of progress in theory development", some ones words.

I believe that pseudoscience is for people that don't want to accept the cold hard truth of the world so they get themselves wraped up in what other "non-experts" say. Science on the other hand is for "geeks" people who always have to be right 100 percent of the time. Just because something such as palm reading cannot be proved doesn't make it false or not real. Science is for people who have trust issuses and always need something to be true or false.
