The immediate and long-term consequences of the Sun vanishing
In short: If the Sun were to suddenly vanish, the Earth wouldn't go dark instantly. This video explores the physics of light travel and the subsequent environmental collapse that would follow.
Because light takes approximately 8 minutes and 20 seconds to travel from the Sun to Earth, we would continue to see the Sun in the sky for that duration after it disappeared. Once that light reaches us, the planet would plunge into total darkness.
The video examines the cascading effects of losing the Sun's gravity and energy, including the Earth's trajectory into deep space and the rapid cooling of the atmosphere.
