Effect of Blue-Shifted GWs on Particles

Click For Summary
SUMMARY

The discussion centers on the interaction between blue-shifted gravitational waves (GWs) and relativistic particles. It posits that the energy of a GW is frequency-dependent, similar to electromagnetic waves. When a relativistic particle interacts with a gravitational wave traveling in the opposite direction, the wave is blue-shifted, potentially increasing its energy significantly. However, the effects of this interaction, especially concerning cosmic rays and ultrarelativistic particles, remain negligible under realistic conditions, even with advanced setups like LIGO operating at relativistic speeds.

I assume that the energy transported by a gravitational wave is dependent on its frequency, just like EM waves. If that is the case, let's imagine a particle traveling at relativistic speeds relative to the lab frame. Let's imagine the interaction of this relativistic particle with a gravitational wave of lab's energy E traveling with speed c and in direction opposite to that of the particle with respect to the lab's frame. With respect to the particle system of reference, the GW will be blue-shifted so its energy could be much higher. Would this high energy interaction produce some effect different to the interaction of a low-energy GW and a "at-rest" particle? Could these hypothetical effects be detected when considering cosmic rays and the sort (ultrarelativistic particles) and background GW interactions?

The intensity increases from "extremely tiny" to "still extremely tiny".

LIGO accelerated to relativistic speeds would see a difference. Particles flying through space don't care. You could hope for particle-graviton interactions, but those would still have negligible impact on the particles for every realistic setup.
