Reply to comment by Aseyhe in How does light factor into gravity models? by littleboymark

Thanks for the answer, very educational. What's the current theory regarding the future of the CMB? How will redshifting change it further?

It will become continuously dimmer and redder, eventually moving into radio frequencies. If dark energy persists, the CMB frequency will halve (wavelength will double) every ~12 billion years.
