a. Squeezed vacuum
b. Hot vacuum
c. Cold vacuum
d. Vacuum

ANSWER: Squeezed vacuum
 
Researchers have developed a fresh technology to make the Advanced Laser Interferometer Gravitational Wave Observatory to become more sensitive to gravitational waves which are faint ripples in space time.
  • MIT and Australian National University team of researchers report on improvements in what is called the squeezed vacuum source
  • Injecting the new squeezed vacuum source into the LIGO detector could help to double sensitivity
  • Scientists announced the first ever observation of g-waves earlier this year 100 years after Einstein predicted their existence in his general theory of relativity
  • In case this is implemented, it will boost the sensitivity of gravitational detectors specifically at higher frequencies vital for understanding the composition of neutron stars
