Question

question 7 (1 point) astronomers spent several centuries looking for evidence that the expansion was decelerating and they were finally successful in the 1990s. true false question 8 (1 point) light takes slightly more than 8 minutes to travel 1 astronomical unit, which means the light we receive from the sun is always 8 minutes old. true false question 9 (1 point) the first force to emerge was that of _? - the fate of the universe was decided in that moment a light b gravity c heat

Explanation:

For Question 7: Astronomers in the 1990s found evidence the universe's expansion was accelerating, not decelerating.
