It causes the expansion of the universe to accelerate.
does dark matter interact with baryonic matter
Yes, dark matter does interact with baryonic matter, although the nature of this interaction is still not fully understood. Dark matter's gravitational influence affects the motion of baryonic matter, such as stars and galaxies, and plays a key role in the formation and evolution of structures in the universe. However, dark matter does not interact electromagnetically, which is why it cannot be directly observed or detected using traditional telescopes or detectors.
does dark matter interact with electromagnetic radiation
No, dark matter does not interact with electromagnetic radiation. It does not absorb, reflect, or emit electromagnetic radiation like visible light, radio waves, or X-rays. This is why dark matter cannot be directly observed or detected using telescopes that rely on detecting electromagnetic radiation. Its presence is inferred indirectly through its gravitational effects on visible matter.

A scientist, using a telescope, sees arcs of light around a galaxy. In 3–5 sentences, explain the cause of the arcs of light.
The arcs of light observed around a galaxy are known as gravitational lensing. This phenomenon is caused by the gravitational pull of the massive galaxy bending the path of light from more distant objects around it. As light passes near the massive galaxy, its path is distorted, resulting in the formation of arcs or multiple images of the background objects. Gravitational lensing provides valuable insights into the distribution of dark matter and the gravitational properties of galaxies.
