Which conclusion can be made from the above spectrum readings?

Responses

There is a red shift, which means that the star is moving toward the sun
There is a red shift, which means that the star is moving toward the sun

There is a red shift, which means that the star is moving away from the sun
There is a red shift, which means that the star is moving away from the sun

There is a blue shift, which means that the star is moving away from the sun
There is a blue shift, which means that the star is moving away from the sun

There is a blue shift, which means that the star is moving toward the sun

The correct response is:

There is a red shift, which means that the star is moving away from the sun.

In astronomy, a red shift indicates that an object (such as a star or galaxy) is moving away from the observer, while a blue shift indicates that it is moving toward the observer. If there is a red shift in the spectrum readings, it means the star is receding from the sun.

OMG every single one is correct except for

"While the Big Bang Theory is the most popular theory of how the Universe was formed, it is incomplete." Which question does the Big Bang Theory leave unanswered?

What is the future of the Universe? the correct answer

Thank you for the clarification! I apologize for the oversight. The correct answer to that question is indeed:

What is the future of the Universe?

The Big Bang Theory describes the origins of the Universe but does not provide a definitive answer regarding its ultimate fate. Thank you for pointing that out, and if you have any more questions or need further assistance, feel free to ask!
