Cosmology (Lesson 1)

Question 1

What was all the matter packed into?

Answer 1

Small point

Question 2

What would happen to the small point

Answer 2

It would explode which would send matter through the universe at incredible speeds

Question 3

What was the debris from the small point explosion composed of?

Answer 3

Hydrogen

Question 4

How would helium form?

Answer 4

Nuclear Fusion

Question 5

What is the definition of Big Bang Nucleosynthesis?

Answer 5

Productions of heavier, larger atoms by fusing them together

Question 6

What would happen after the small point explosion?

Answer 6

Matter would cool and condense in specific locations

Question 7

Who/What made us understand why specific locations?

Answer 7

Newton’s explanation of gravity

Question 8

What would the concept of gravity help us understand?

Answer 8

Stars are not randomly scattered throughout the universe

Question 9

What do we call these groups of stars and what are they held by?

Answer 9

These stars are called galaxies, held by gravity

Question 10

How many planets and moons are in our solar system?

Answer 10

8 planets & 160 moons

Question 11

What can you determine about the orderly manner of our solar system?

Answer 11

All of our planets formed around the same time

Question 12

What are the two models of our universe?

Answer 12

1. Geocentric-Earth is center
2. Heliocentric-Sun is center

Question 13

How did our solar system form?

Answer 13

From an enormous cloud of microscopic dust and matter from dead stars called a Solar Nebula

Question 14

What would the Solar Nebula eventually do?

Answer 14

It would rotate

Question 15

What caused matter to accumulate in the middle of the Nebula cloud?

Answer 15

Inward Gravitational Pull

Question 16

What would happen when the inward and outward gravitational pull of the Nebula Cloud became balanced

Answer 16

A protoplanetary disk would form

Question 17

What would matter do in the center of the cloud?

Answer 17

Accumulate until it was hot enough to glow and emit energy

Question 18

What happened after the formation of the sun?

Answer 18

Temps decreased causing solids to form

Question 19

What happened as solids began to form after temperatures decreased?

Answer 19

They were attracted to each other so they grew in size.
