← ScienceWhich consequence reliably follows when accelerating a spacecraft?
A)Increased observed mass of the craft✓
B)Decreased proper time of the crew
C)Blueshift of emitted radio signals
D)Gravitational repulsion from celestial bodies
💡 Explanation
The observed mass increases because of _mass-energy equivalence_; acceleration adds energy, which manifests as increased relativistic mass, therefore the spacecraft appears heavier. The crew experiences proper time normally, and gravitational effects depend on spacetime curvature, rather than acceleration.
