SUMMARY

The discussion centers on the detection of gravitational waves, specifically through LIGO, in relation to massive objects traveling at relativistic speeds. A LIGO physicist confirmed that gravitational waves from collapsing stars are being detected. The conversation highlights the Doppler effect's influence on gravity and the feasibility of detecting large masses moving close to the speed of light using LIGO or similar interferometers. It concludes that only accelerated masses can emit gravitational waves, with significant events involving several solar masses being necessary for detection.

PREREQUISITES
  • Understanding of gravitational waves and their detection methods, specifically LIGO and VIRGO.
  • Knowledge of the Doppler effect and its implications in astrophysics.
  • Familiarity with relativistic physics and the concept of mass acceleration.
  • Basic principles of interferometry as applied in gravitational wave detection.
NEXT STEPS
  • Research the principles of gravitational wave detection using LIGO and VIRGO.
  • Study the Doppler effect in the context of astrophysical phenomena.
  • Explore the implications of relativistic speeds on mass and gravitational wave emission.
  • Investigate advanced interferometry techniques for potential future applications in detecting high-speed masses.
USEFUL FOR

Astrophysicists, physicists interested in gravitational wave research, engineers working on interferometry, and anyone studying relativistic effects in astrophysics.

I saw a conference from a Ligo physicist she said they are detecting gravitation wave of collapsing star. I also read the Doppler effect is working on gravity due to limited speed (c). I want to know if it is possible to detect a big mass traveling close to the speed of light in ours frame of reference using Ligo or a similar interferometer?

Only accelerated masses can radiate gravitational waves. In principle the launch or deceleration of such a spacecraft might be detectable but keep in mind the scale of the events LIGO/VIRGO need to see something: Several solar masses getting accelerated to relativistic speeds in a few milliseconds.
