ANSWER: Squeezed vacuum
Explanation:
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
