At this point, she paused, a bitter smile appearing on her face, and said, "If the gamma-ray burst hadn't been intercepted, perhaps we wouldn't have had the chance to witness this scene, because the signal transmitted back from Venus takes about twenty-three minutes, and gamma-ray bursts travel at the speed of light, able to traverse 300,000 kilometers per second. Twenty-three minutes would be enough for the gamma-ray burst to travel over 400 million kilometers. In fact, the Earth is only about 40 million kilometers away from Venus, so if the gamma-ray burst hadn't been stopped, by the time we discovered it, Earth would already have been struck. Or we might never see it, because gamma-ray bursts are the strongest electromagnetic waves in the universe; they disrupt our signals, making it impossible for us to receive transmissions from probes or satellites, or they can even destroy the probes or satellites themselves."
