← ScienceWhich distortion relates to gravitational waves affecting spacetime?
A)Changes in spacetime's curvature✓
B)Variations in baryonic matter ratios
C)Increase of background microwave radiation
D)Redshift decreasing between source observer
💡 Explanation
Gravitational waves cause changes in spacetime's curvature, which is their defining characteristic according to Einstein's theory of general relativity, therefore spacetime's curvature changes, rather than changes to matter ratios or energy shifts happening.
