Which author described gravitational waves as squeezing and stretching the fabric of space?

• A. Jana Levin
• B. Stephen Hawking
• C. Kip Thorne
• D. Carl Sagan

Answer: (A)

Gravitational waves are distortions of spacetime that make distances oscillate as they pass. Describing this as space being squeezed in one direction and stretched in the perpendicular direction is a clear, intuitive way to picture how the geometry itself changes, not a material medium being stretched. Jana Levin is known for using that exact image to explain how gravitational waves affect space, linking the idea directly to the way spacetime is warped and then relaxes as the wave moves through. In relativity, gravity isn’t a force in a medium but a feature of spacetime geometry that can ripple like a wave, producing tiny tidal distortions that alternate in direction. Detectors like LIGO rely on measuring these minute changes in distance between mirrors to confirm the passage of a wave. That vivid phrasing helps students grasp why spacetime itself is transiently stretched and squeezed by these waves, making her description the best match for this idea.
