Gravitational Waves from the Big Bang

• similar to cosmic microwave background in electromagnetic spectrum.
• Planck scale relic produced a fraction of a second after birth of universe.
• gravitational waves come from all directions and at all frequencies.
• net effect is random (Gaussian) pattern of distortions.
• typical expected parameters:
  • distortions much less than 10^-23.
  • all frequencies.
  • cosmological durations.
• audio representation is here.
