Q.1
The faster a star or galaxy is moving (relative to us), we say that the redshift is …
  • bigger
  • smaller
  • the same
  • There is no correlation between speed and size of red-shift
Q.2
What happens to the wavelength of light from stars that are moving away from us?
  • It gets shorter
  • It doesn't change
  • It gets longer
  • It goes zig zag
Q.3
If scientists find new evidence that doesn’t support the Big Bang Theory, what should other scientists do?
  • Have a party
  • Ignore the evidence and keep on believing what they always have
  • Dismiss them as crackpots
  • Test the evidence to ensure that it is reproducible
Q.4
How do we know that the Universe is currently expanding?
  • Light waves from distant galaxies are shifted so that they appear redder than they normally would
  • Light waves from distant galaxies are shifted so that they appear bluer than they normally would
  • Gamma waves from distant galaxies are shifted so that they appear redder than they normally would
  • Delta waves from distant galaxies are shifted so that they appear redder than they normally would
Q.5
How do we know black holes exist if we cannot see them?
  • They bend light
  • They emit a very specific type of radiation
  • Objects near them orbit around them
  • All of the above
Q.6
"In space no one can hear you scream" was a famous movie quote, but is that actually true and why?
  • It is not true
  • It is true. Sound waves need particles to vibrate to travel. In space, particles are few and far between so sound cannot travel through space
  • It is not true, but we don't know why
  • It is true. Space is too cold for sound waves to travel
Q.7
How long does it take the light from the sun to reach us?
  • Instantly
  • 2 minutes
  • 8 minutes
  • 20 minutes
Q.8
The shift seen when an object is moving towards us is not red, it is …
  • pink
  • blue
  • green
  • black
Q.9
What types of radiation are emitted by the Sun?
  • Infra-Red
  • Ultra-Violet
  • Light
  • All of the above
Q.10
What is blueshift?
  • When blue light is emitted from a source
  • When an object is moving towards an observer, the light emitted from the object is shifted to the blue part of the spectrum
  • When an object is moving towards an observer, the light emitted from the object is shifted to the red part of the spectrum
  • There is no such thing as blue shift
