Which are accurate statements about dark matter? Select the TWO correct answers.
A. Scientists are not convinced that dark matter exists
B. Scientists thoroughly understand what dark matter is and what it does
C. New data could cause scientists to change their hypothesis about dark matter
D. Scientists have hypotheses about dark matter but need more date to test their ideas
C. New data could cause scientists to change their hypothesis about dark matter
D. Scientists have hypotheses about dark matter but need more data to test their ideas
The accurate statements about dark matter are:
C. New data could cause scientists to change their hypothesis about dark matter
D. Scientists have hypotheses about dark matter but need more data to test their ideas
To determine the accurate statements about dark matter, we need to evaluate each option.
A. Scientists are not convinced that dark matter exists: This statement is not accurate. Scientists have strong evidence, such as gravitational effects and the observations of galaxy rotation curves, that suggest the existence of dark matter. However, they are still working to understand its nature more fully.
B. Scientists thoroughly understand what dark matter is and what it does: This statement is not accurate. Dark matter remains a mystery to scientists, and they are actively studying and researching its properties. While they have made significant progress, a complete understanding of dark matter is yet to be achieved.
C. New data could cause scientists to change their hypothesis about dark matter: This statement is accurate. The scientific method involves developing hypotheses based on available evidence, and as new data becomes available, scientists are open to revising their hypotheses. Dark matter is a field of ongoing research, and the discovery of new information could potentially alter our understanding.
D. Scientists have hypotheses about dark matter but need more data to test their ideas: This statement is accurate. Scientists have put forward various hypotheses to explain dark matter, such as weakly interacting massive particles (WIMPs) or primordial black holes. However, gathering additional data is crucial to test these ideas and refine our understanding of dark matter.
Therefore, the two accurate statements about dark matter are:
C. New data could cause scientists to change their hypothesis about dark matter
D. Scientists have hypotheses about dark matter but need more data to test their ideas.
