Blog 17: Third Answer

1.) EQ 

- What is the best solution for detecting gravitational waves?

2.) Answer #3 (Write in a complete sentence like a thesis statement)*

- Weber Bars could detect gravitational waves with their use of heavy aluminum cylinders to see any change in frequency, disregarding "background noise".

3.) 3 details to support the answer (a detail is a fact and an example)

• These massive aluminium cylinders vibrated at a resonance frequency of 1660 hertz and were designed to be set in motion by gravitational waves predicted by Weber. 
• Because these waves were supposed to be so weak, the cylinders had to be massive and the sensors had to be very sensitive.
• These sensors are capable of detecting a change in the cylinders' lengths by about 10⁻¹⁶ meters.

4.) The research source (s) to support your details and answer

- Lindley, David. "A Fleeting Detection of Gravitational Waves." Physics -. American Physical Society, 22 Dec. 2005. Web. 05 Mar. 2015. <http://physics.aps.org/story/v16/st19>

5.) Concluding Sentence

- My 3rd answer differs from my first two since Weber Bars are much more restrictive and crude compared to the others, but can still work given the right conditions.
