Origins of the Universe

The Big Bang Theory

Open Ended

What do you know about the origins of the universe?

The Universe

All existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.

What's This Big Bang All About?

The Big Bang Theory is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!

Multiple Choice

What is the Doppler effect?

• CHANGE in frequency due to motion of the source

Multiple Choice

If you are standing in FRONT of this car, the wavelengths nearest you would have a _______ frequency

• LOWER

• HIGHER

• Person A, because the wavelengths are squished shorter as the car approaches

• Person A, because the wavelengths are stretched longer as the car approaches

• Person B, because the wavelengths are squished shorter as the car approaches

• Person B, because the wavelengths are stretched longer as the car approaches
