Ar. Liddle, CAN THE GRAVITATIONAL-WAVE BACKGROUND FROM INFLATION BE DETECTED LOCALLY, Physical review. D. Particles and fields, 49(8), 1994, pp. 3805-3809
The Cosmic Background Explorer (COBE) detection of microwave backgroun
d anisotropies may contain a component due to gravitational waves gene
rated by inflation. It is shown that the gravitational waves from infl
ation might be seen using ''beam-in-space'' detectors, but not the Las
er Interferometer Gravity Wave Observatory (LIGO). The central conclus
ion, dependent only on weak assumptions regarding the physics of infla
tion, is a surprising one. The larger the component of the COBE signal
due to gravitational waves, the smaller the expected local gravitatio
nal wave signal.
