Question 606 • Career Explorations A

What do scientists know about the future of the universe?

Answer
A
what dark matter is made of
B
why the expansion of the universe is accelerating
C
that stars will eventually burn out causing the universe to become cold and dark
D
that galaxies spin much slower than they should based on visible matter

Explanation

Scientists can predict that stars will eventually use up their fuel and stop shining. Over immense spans of time, the universe would then become colder and darker. The other choices describe unanswered questions or observations about dark matter, cosmic acceleration, and galaxy rotation—not established predictions about the universe’s eventual fate.
