Does Dark Matter Radiate "Space" much as Normal Matter Radiates "Time" (when Travelling Slower than the Speed of Light/ Causality)?

from Google AI:

No, time is not a form of radiation. While time and radiation interact within the framework of physics (such as using radiation cycles to measure time), time is generally understood as a fundamental dimension, a measurable dimension of spacetime, or a conceptual framework for ordering events, rather than energy propagating through space. 

Key points to understand the distinction:

What is Radiation? Radiation is energy—either particles or electromagnetic waves—that travels through space, such as light, heat, or X-rays.

What is Time? Time is a fundamental physical quantity used to measure the duration and sequence of events, and is a dimension of the space-time continuum.

Measurement Role: Atomic clocks use the, “9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom” to define a second. In this case, radiation measures time, but is not time itself.

Fundamental Difference: Some theories suggest time may be an emergent property or an illusion, whereas radiation is a tangible energy output within that framework.
