Which statements explain current theories about dark energy and dark matter?Check all that apply. Space that appears empty actually contains dark energy and dark matter. Dark matter does not emit electromagnetic radiation. Scientists believe dark energy will cause the universe to collapse inward to a single point. Scientists theorize that dark energy is causing the expansion of the universe to accelerate. Dark matter includes all of the dust, ice and debris that scientists observe in black holes.

## Step 1<br />The problem presents a set of statements about dark energy and dark matter, and asks us to identify which of these statements are accurate according to current scientific theories.<br /><br />## Step 2<br />The first statement, "Space that appears empty actually contains dark energy and dark matter," is a simplified way of explaining the existence of dark energy and dark matter. While it's not entirely accurate, it does capture the idea that these entities are present in space, even though we can't see them.<br /><br />## Step 3<br />The second statement, "Dark matter does not emit electromagnetic radiation," is correct. Dark matter is hypothesized to be composed of particles that do not interact with electromagnetic radiation, which is why we can't detect it using traditional methods.<br /><br />## Step 4<br />The third statement, "Scientists believe dark energy will cause the universe to collapse inward to a single point," is incorrect. The current understanding of dark energy is that it is causing the universe to expand, not collapse.<br /><br />## Step 5<br />The fourth statement, "Scientists theorize that dark energy is causing the expansion of the universe to accelerate," is correct. This is the primary role of dark energy in the current cosmological model.<br /><br />## Step 6<br />The fifth statement, "Dark matter includes all of the dust, ice and debris that scientists observe in black holes," is incorrect. Dark matter is hypothesized to be a separate entity from the matter we can observe in black holes.
