Why do stars twinkle if the light we’re seeing is from thousands of years ago and most things aren’t big enough to block its light?
Stars twinkle due to atmospheric interference. If you've ever seen "heat waves" shimmering above a road, you're seeing a similar principle at work. Gasses can cause interference with light passing through them.
The Short Answer
Stars twinkle due to atmospheric interference. If you've ever seen "heat waves" shimmering above a road, you're seeing a similar principle at work. Gasses can cause interference with light passing through them. In the case of a twinkling star, you're seeing the atmosphere scattering the light as it passes through.
