Which are accurate statements about dark matter? Select the two correct answers. (1 point)
• Scientists thoroughly understand what dark matter is and what it does.
• Scientists have hypotheses about dark matter but need more data to test their ideas
• New data could cause scientists to change their hypotheses about dark matter.
• Scientists are not convinced that dark matter exists
• Scientists have hypotheses about dark matter but need more data to test their ideas
• New data could cause scientists to change their hypotheses about dark matter.

Explanation:
Dark matter is a hypothetical form of matter that does not interact with light or other forms of electromagnetic radiation, making it difficult to detect directly. Scientists have developed various theories and hypotheses to explain the observed gravitational effects that cannot be accounted for by visible matter. However, despite extensive research, the nature and composition of dark matter remain uncertain.
The first accurate statement reflects the current understanding that scientists have formulated hypotheses about dark matter. These theories provide a framework for studying and investigating its properties further. However, due to the elusive nature of dark matter, additional data collection and experimentation are needed to test these hypotheses and gain a deeper understanding of its characteristics.
The second accurate statement acknowledges that new data and evidence have the potential to change scientists' current hypotheses about dark matter. As scientific knowledge progresses and observational techniques improve, there is always room for revisions and refinements in our understanding of the universe.
On the other hand, the statements "Scientists thoroughly understand what dark matter is and what it does" and "Scientists are not convinced that dark matter exists" are not accurate. The complex nature of dark matter and the challenges in detecting it prevent scientists from having a complete understanding of its properties. While there is ongoing research and debate, the majority of the scientific community accepts the existence of dark matter based on its gravitational effects observed in the universe.
