Blog 16: Answer 2

1.)  What is your EQ?

- My EQ is "What is the best solution for detecting gravitational waves?"
2.)  What is your first answer? (In complete thesis statement format)

- Interferometers could detect gravitational waves with the usage of laser to see changes in space-time.
3.)  What is your second answer? (In complete thesis statement format)

- Pulsar Timing Arrays could detect gravitational waves with their perturbation-seeking-sensors through pulsars.
4.)  List three reasons your answer is true with a real-world application for each.

• The signal from a pulsar can be detected by radio telescopes as a series of regularly spaced pulses, essentially like the ticks of a clock.
• Gravitational waves affect the time it takes the pulses to travel from the pulsar to a telescope on Earth.
• A pulsar timing array uses millisecond pulsars to seek out perturbations due to gravitational waves in measurements of pulse arrival times at a telescope, in other words, to look for deviations in the clock ticks.

5.)  What printed source best supports your answer?

- Feynman, Richard P. QED: The Strange Theory of Light and Matter. Princeton, NJ: Princeton UP, 1985. Print.

6.)  What other source supports your answer?

- Moskowitz, Clara. "Dark Matter Black Holes Could Be Destroying Stars at the Milky Way's Center." Scientific American Global RSS. Scientific American, 10 Nov. 2014. Web. 12 Dec. 2014.
7.)  Tie this together with a concluding thought.

- My new answer differs from the 1st because pulsar timing arrays would scan the universe's space-time instead of looking directly at the waves, like a inteferometer does.
