What is cosmic microwave background (CMB)?

leftover radiation from the Big Bang, or the time when the universe began.

radiation that is used to determine distances between planets

radiation coming from the core of a planet

radiation from the exhaust of UFOs

What is the doppler effect?

observed change in the frequency of a wave when the source is moving

What are the three main evidences for the Big Bang Theory?

Red shift, Cosmic Background Radiation, expansion of the universe

Axions, supernovas, the presence of iron in some stars

Asteroids, cosmic radiation, comets

The study of the universe as a whole

The study of gravity between planets

The study of light travel in galaxies

Which on of these ideas is a known fact that is confirmed by science?

Light from the distant galaxies is red shifted.

The universe has expanded and contracted many times

The Earth and moon formed millions of years apart

A gamma ray bust is evidence of

satellite returning to the atmosphere

Why can't scientists confirm the existence of Hawking radiation?

They are limited by the extreme distances and can't yet make a device that could find it.

It's being hidden by the government

This is a trick question. It's already been extensively studied and examined.

Which of these is a carefully researched and experimentally confirmed scientific theory?

Animal Migration Mechanism Theory

a hypothetical form of matter that is believed to make up 85 percent of the matter in the universe

Equal to the amount of visible matter

Scientists have discovered the light from distant stars in all directions is red shifted. The logical conclusion from this information is

the universe is expanding in all directions

light and sound cancel each other out

the equipment we are using must be flawed

Santa Clause is coming to town.

This time lapse photo of star trails was taken from

the northern hemisphere, looking to the north

the International Space Station

the earliest person to use a telescope to observe the planets

the name given Venus setting - "the evening star"

creator of the worlds's first star catalog

proposed a heliocentric solar system

was the first to observe the sky through the Hubble telescope

was famous for his chicken recipes

believed that Earth was the center of the universe

Henrietta Leavitt used the variable cepheid stars to demonstrate that some stars have a consistent absolute magnitudes. She used this fact and their apparent magnitudes to determine

the type of fusion they were using to produce light

Edwin Hubble used Henrietta Leavitt's research that showed how to determine distances in space to further prove that

satellites can be launched and maintained around the earth

the universe is expanding, and the farther you look the faster it expands

the telescopes can be operated from any point

the moon is made of Swiss cheese

An important piece of evidence for dating the Universe at 13.8 billion years old is

the wavelength of the observed Cosmic Background Radiation

the laters of rock on the Earth

the amount of helium in the Sun

presence of liquid water on Earth

Ancient civilizations used astronomy to

Create religious sites and festivals

What is the difference between astrology and astronomy?

Astronomy is a science and astrology is a belief system

Astronomy is a career and astrology is a musical style

Both of them are pseudoscience.

It's just spelling. There's no difference.

Which of the following is true when comparing the two graphs below?

Wave B has a greater amplitude.

Wave A has a greater frequency.

Wave B has a greater frequency.

Wave A has a greater amplitude.

After taking a hot shower, James steps out of the shower on to the tile floor. The tile floor felt cold to his feet. Which explanation below best describes James' experience?

Heat from his feet is transferred to the tile floor.

Heat from the tile floor is transferred to his feet.

Cold from the tile floor is transferred to his feet.

Cold from his feet is transferred to the tile floor.

Which of the following best describes the application of the first law of thermodynamics in a star?

The energy produced through nuclear fusion in a star is converted into heat and radiated as light, maintaining energy conservation.

The energy produced in the core of a star is lost to space and does not contribute to the star's luminosity.

The energy output from a star decreases as the star ages, with no increase in internal energy.

A star undergoes no energy loss or gain as it evolves.

How does the second law of thermodynamics explain the overall evolution of the universe?

Over time, entropy increases, leading to the eventual "heat death" of the universe.

The universe will eventually reach a state of maximum energy concentration.

Entropy in the universe is always decreasing, leading to an increase in order.

Energy in the universe is conserved but can transform between different types without affecting overall disorder.

Both sound waves and electromagnetic radiation

require a medium to move through space.

can move through space without a medium.
