Session 1 – Introduction to Astronomy

Astronomy - The branch of science that deals with celestial objects, space, and the physical universe as a whole.

Cosmology – The study of the origin and large scale function of the universe

In this session we will look at an overview of these topics in reference to Biblical Creation vs. Naturalism Slide2

Genesis 1:1

“In the Beginning God Created the heaven

and the earth”

The Bible says the universe (Time, Space, and Matter) had a beginning

Psalm 147:4:

He telleth the number of the stars; he calleth them all by their names.”

The Bible also says the universe is finite in size Slide3

For a long time cosmologists believed the universe was eternal and infinite in size! They were wrong.

Keep in mind, the majority (vast) of scientists for thousands of years held to that view, and even though the majority thought it, it was still able to be wrong

Many today are trying to revisit this question to remove the implications of a beginningSlide4

Why is having a beginning a problem?

Principle of causality

- Everything that has a beginning must have a cause

Principle of causality

- Everything that has a beginning must have a

cause

How do we know that the universe has not always existed?

Norman Geisler put it well when he said the following:

When we consider the consequences of a universe that obeys the second law (of thermodynamics

)…Slide5

there is only one logical conclusion: The universe will eventually run out of usable energy. Since there is no place for the universe to obtain more fuel; we live in a finite universe”

The temperature of space is decreasing, showing that the overall energy and heat of the universe is going down! Which means it had a starting pointSlide6

Psalm 19:1-4 “The heavens declare the glory of God; and the firmament shows His handiwork. 2 Day unto day utters speech, and night unto night reveals knowledge. 3 There is no speech nor language where their voice is not heard. 4 Their

line has gone out through all the earth and their words to the end of the world.”

Why did God create everything?

So we can see his power through itSlide7

When we look out into the universe

there is quite a bit out thereFor thousands of years people have been trying to understand the universe scientifically and philosophically

We will take a minute now and look at the structure of the universe

Another thing you notice when examining the universe is what we call the Anthropic

principle in cosmology and astronomyPaul Davies said: “A clear inspection shows that the Earth is endowed with still more amazing “conveniences.” Without the layer of ozone above the atmosphere, deadly ultraviolet radiation from the sun would destroy us, and in the absence of a magnetic field, cosmic subatomic particles would deluge the Earth’s surface. Slide21

Considering that the Universe is full of violence and cataclysms, our own little corner of the cosmos enjoys a benign tranquility. To those who believe that God made the world for mankind, it must seem that all these conditions are in no way a random or haphazard arrangement of circumstances, but reflect a carefully prepared environment in which humans can live comfortably, a pre-ordained ecosystem into which life slots naturally and inevitably—a tailor-made world” (1980, p. 143).”Slide22

Anthropic Constant: Gravity

If the universal law of gravity were slightly different than it is, life would not be possible!

Anthropic Constant: Centrifugal Force

Anthropic Constant: Rate Of

Expansion of the universeSlide23

Anthropic Constant: Speed Of Light

Anthropic Constant: The Earth’s Rotation.

If the speed of light were different, life would not be possible in our universe.

The amount of daylight versus night time is perfect for the existence of lifeSlide24

Anthropic Constant: Axis Tilt.

Anthropic Constant: Jupiter.

Jupiter acts like a big gravitational shield protecting the earth and the inner solar system from material that could destroy us

The axial tilt controls seasons, and is

perfect for life as it isSlide25

Genesis 1:14-19 (Day 4 of creation) “And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and

years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made

the stars also…Slide26

…And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day.”

This is not the view point of the secular world though, and they have instead created theories over time to explain thingsSlide27

Many Cosmologies have existedSlide28
Slide29

Many people do not understand what the

big bang theory actually says about the origin of the universeWhen dealing with opposing theories, we need to accurately represent what they

say if we are going to have an effective witness one people

The most common misconception with the big bang is how it happenedSlide30

Many people think of the big bang as being an explosion in space that produces everything! That’s wrong. Slide31

This is more accurateSlide32

Many Christians have embraced the Big Bang model because they think it proves that

the universe had a beginning point (and therefore a cause)Understand, while the big bang does fit within the data that says the universe had a beginning, it is not something that is because of the big bang

The decreasing energy and temperature of space shows it had a beginningSlide33

What the order of events in the

secular big bang model?13.75 billions years ago, the big bang happens and the universe comes into existenceSlide34

4.6 billion years ago the sun was birthed from dust clouds in space

After the sun (a star) forms, the debris left over can create other things like planetsSlide35

4.55 billion years ago, our planet (earth) formed from material left overSlide36

What are the Biblical problems?Slide37

We will not delve into the problems with the big bang theory until next session

While we do think this is an important issues, and while we do think accepting the big bang theory is compromising the creation account, this is not an issues to divide over!

Godly Christian men and women believe in the big bang theorySlide38

Not everyone in the secular world

accepts the big bang theory thoughMany still have scientific and philosophical problems with the implications of the big bang (a starting point to time)

Physicist today are working on models that can allow for the universe to exist forever, eliminating the necessity for causeSlide39

But does an infinite universe even make sense philosophically

or scientifically? David Hilbert, perhaps the greatest mathematician of the twentieth century, states

, “The infinite is nowhere to be found in reality. It neither exists in nature nor provides a legitimate basis for rational thought. The role that remains for the infinite to play is solely that of an idea.”Slide40

If the universe never had a beginning, that means that the number of past events in the history of the universe is infinite. But mathematicians recognize that the existence of an actually infinite number of things leads

to self-contradictions.Slide41

Here is an example:

Earth rotates around the sun every 365 days, while Neptune rotates around

the sun every 60,000 days

Neptune takes 164 earth years to

orbit the sunSlide42

If you assume they have been orbiting the sun for an infinite time, which one has orbited the sun the most?

Mathematically they would have rotated the sun the same amount (infinity)

Things like this make infinity a mathematical and logical problemSlide43

Memory Verse

Colossians 1:17: “And he is before all

things, and in him all things hold together”
