- The discovery of the dark energy was a surprise because astrophysicists generally assumed that the expansion would be slowing down. Select one: True FalseIf a standard passenger aircraft can fly at 0.32 km/s (716 mph), how long (in yr) would it take to reach the sun? ______ yr How long (In yr) would it take to reach the galactic center? (Note: 1 pc = 3.1 x 10^13 km. The radius of the suns orbit around the galactic center is approximately 8,300 pc.) ______ yrHow long will a 7 solar mass balck hole live?
