An Open universe is a universe which will continue to expand. If a Universe is “open”, then it will expand until all of eternity. We also see the fact that the C-R theory stops the universe from being open or expanding. If the universe has a mass which has enough to close off space, then the universe is basically located within a huge Black-hole. Basically this means that the universe will be stopped from expanding forever.

Investigate other theories of the origin of the universe or suggest your own.

The origin of the universe is a topic which is debated by many different groups. In religions, their is a theory by both theists and atheists. Theists have a belief that the universe began from an intelligent designer. In the 1900’s the Atheists believed that the universe was “eternal.” This opinion was later proven incorrect in the 20th Century such as Einstein’s and Hubble’s theories.

1 State how old the universe is thought to be

The universe is thought to be approximately 14 billion years ago.

2. Identify the time when the young universe suddenly inflated.

The time that the universe suddenly inflated was within a fraction of a second when the universe began to expand fairly slowly

3. Matter and antimatter didn’t totally destroy each other after the big bang. Explain why it is lucky that this didn’t occur.

4. Identify what particles grouped into threes to form protons and neutrons.

Particles called quarks grouped together to form protons and neutrons.

5.  a) State the proportion of hydrogen in the universe.

     b) Explain why hydrogen is the most common element

     Hydrogen is the most common element because it is a substance which is found in almost everything in the universe.

6. Describe what is in a hydrogen nucleus

 In a hydrogen nucleus you can find 2 hydrogen atoms and one oxygen atom

7. Explain why the early universe was opaque.

The early universe was opaque because it contained energy in the form of radiation

8. Describe the effect on the ‘fog’ of the continuing expansion of the universe.

The continuing expansion of the universe caused more radiation.

9. Penzias and Wilson detected evidence for the Big Bang. Clarify the evidence they collected.

Penzias and Wilson produced an image of the universe when it was 300 000 years old. They collected this via the COBE satellite.

10. State what the acronym COBE stands for.

COBE stands for (Cosmic Background Explorer)

This is when the universe was created. It all began with the Big Bang, which was a cataclysm. From this the Universe was formed. At this time the universe was very hot and dense. Soon after it began to cool down and also it started to expand.

Universe begins to shape

After 1 millionth of a second, the universe continues to expand however it becomes less dense and it cools down. Some things which we would know, began to appear. Things such as gravity.

Galaxies begin to form soon after. The universe at this stage did not have an even distribution of energy particles. This gave the forces an opportunity to start collecting matter.

Gather information about:

a) Hubble’s involvement in Space Research

Hubble was a key figure in the 20th Century. Edwin Hubble was one of the greatest every astronomers in the world. It was Hubble who came up with the theory that the galaxy in which we live in (The Milky Way) was not the only galaxy which existed in the universe. He is named after one of the famous telescopes called the “Hubble Space Telescope.” By the end of the 1920’s Hubble had created a system for classifying galaxies. Hubble has made a discovery of approximately 46 kinds of galaxies in the universe. Without the knowledge and the brains of Edwin Hubble, our world would not have known some of the many wonders in the universe.

b) What the space telescope does.

The Hubble Space Telescope was designed to provide clear views of the galaxy.

c) Where it is

The Telescope is located in orbit around the earth.

d) What Hubble’s constant is
