← ScienceWhich consequence results when an Alcubierre drive compresses spacetime?
A)Causality violations become theoretically possible✓
B)Gravitational lensing affects star visibility
C)Hawking radiation exceeds vacuum constraints
D)Nuclear binding energy fluctuates rapidly
💡 Explanation
Causality violation is theoretically possible because spacetime compression via **exotic matter** could allow faster-than-light travel, causing closed timelike curves. Therefore, backward time travel might occur, rather than gravity or changes in energy, under specific constraints.
