Unit 1 test The origing of universe

The scientific method is a ​ (a)   that can be used to answer a​ (b)   . The process begins when a scientist makes an ​ (c)   that catches their attention. Then, they do ​ (d)   to learn more about the topic and write a ​ (e)   than can be tested.

• guess
• prediction
• scientific law

The scientist will design and conduct a(n) ​ (a)   , where a ​ (b)   variable is established which consists of a manipulation of the experiment, which produces an effect called ​ (c)   variable. Eventually coming to a ​ (d)   . They will share their ​ (e)   with other scientists to help further discovery.

Astronomer Edwin Hubble made two discoveries in 1920. What were they and what inference can be made from that evidence?

• Milky Way is not the only galaxy

• The universe is infinite and static

• The universe began from the Big bang

• The galaxies are constantly moving away from each other

What is the reasoning behind the scientific theory of the Big Bang?

• If the universe is always getting bigger, then at some point it will stop

• If the universe is always getting bigger, then long ago it was much smaller than an atom

• If the universe is always getting bigger, at some point it will contract and collapse

• If the universe is always getting bigger, At some point it will contract and collapse

What is the relationship of a nebula to our Solar system?

• Our solar system is the only one that does not come from a nebula

• God created nebulas just like our solar system

• Our sun and solar system arose in a nebula like other stars

• Our solar system can form nebulae

Our planet ​Earth is located in the ​ (a)   , which is located in the ​ (b)   , located in the Orion arm in the​ (c)   galaxy. Our galaxy is part of Local gallactic group located in the ​​ (d)   , located in a bigger super cluster called ​ (e)   , forming part of the cosmic web in the Observable universe.

• Milky way
• Solar interstellar Neighborhood

What does E=mc² mean?

• Energy is equal to the distance traveled by the speed of light squared

• Matter produces energy and heat when is moved to the square of the speed of light

• Energy and mass (matter) are interchangeable; they are different forms of the same thing.

• If you want to understand the universe, think in terms of frequency and quantum vibrations
