a. Cat flap switches
b. Cat flap boxes
c. Cat flap chests
d. Cat flap pendulums

ANSWER: Cat flap pendulums
 
Scientists from the University of Western Australia have identified gravitational waves through the observable universe instead of detecting the same a billion light years away. This could lead to numerous gravity wave events being recorded every day.
  • This cutting-edge technology involved tiny new devices known as "cat-flap" pendulums less than a millimetre in size which would be fitted to existing gravitational wave detectors.
  • Scientists announced in February 2015 that they had observed ripples in the fabric of space-time called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe.
  • The finding confirmed Albert Einstein’s 1915 general theory of relativity and opened a new window to the cosmos.
