Which of the following is not a characteristic of WIMPs, if they exist as dark matter?

WIMPs, or Weakly Interacting Massive Particles, are hypothesized as candidates for dark matter. They are theorized to possess several key characteristics that differentiate them from ordinary matter and other dark matter candidates.

One important characteristic of WIMPs is that they interact through weak forces, which means they would rarely interact with normal matter. This is part of what makes them difficult to detect directly. In addition, WIMPs are conceived to be massive compared to ordinary particles, giving them a significant gravitational influence, which is critical for their role in galaxy formation and structure. Their stability over cosmic timescales is also a critical aspect; WIMPs would not decay into other forms of matter quickly, allowing them to remain as a significant component of the universe's mass-energy content over billions of years.

The idea that WIMPs travel at speeds close to the speed of light does not align with the characteristics expected of them. While they can move at various speeds, WIMPs are generally thought to have non-relativistic speeds on average, especially in the context of their presence in the galactic halo. Their mass and the dynamics of galaxy formation suggest that their velocities would not typically approach light speed. Therefore, this distinguishing feature makes it clear
