Which are accurate statements about dark matter? Select the two correct answers.(1 point)
Responses
Scientists have hypotheses about dark matter but need more data to test their ideas.
Scientists thoroughly understand what dark matter is and what it does.
Scientists are not convinced that dark matter exists.
New data could cause scientists to change their hypotheses about dark matter.
The accurate statements about dark matter are:
1. Scientists have hypotheses about dark matter but need more data to test their ideas.
4. New data could cause scientists to change their hypotheses about dark matter.
The correct statements about dark matter are:
1. Scientists have hypotheses about dark matter but need more data to test their ideas.
3. New data could cause scientists to change their hypotheses about dark matter.
To determine the accuracy of these statements, one can rely on the scientific method and the current understanding of dark matter.
Statement 1 is accurate because scientists do have hypotheses about dark matter, but they require additional data to verify or refute these ideas. Dark matter is still a topic of ongoing research and exploration.
Statement 3, which states that scientists are not convinced that dark matter exists, is not an accurate statement. The prevailing consensus among scientists is that dark matter is a real phenomenon based on various lines of indirect evidence, such as gravitational effects on visible matter and the cosmic microwave background radiation.
Statement 2, stating that scientists thoroughly understand what dark matter is and what it does, is not accurate either. While scientists have gathered substantial evidence for the existence of dark matter, its exact nature and behavior remain elusive. It is called "dark" because it does not interact with light or electromagnetic radiation, making its direct detection and understanding challenging.
Therefore, the accurate statements about dark matter are that scientists have hypotheses but need more data for testing (statement 1) and that new data could potentially lead to changes in scientists' hypotheses about dark matter (statement 4).
The accurate statements about dark matter are:
1. Scientists have hypotheses about dark matter but need more data to test their ideas.
4. New data could cause scientists to change their hypotheses about dark matter.
These statements reflect the current understanding of dark matter in scientific research, which acknowledges that while there are ideas and theories about dark matter, more data is needed to confirm or refine these hypotheses. Additionally, the possibility of new data leading to changes in scientific understanding is always a fundamental aspect of scientific inquiry.
