Original Note:
Lasers are a form of light. Atmospheric refraction can bend it following Earth’s curvature, deflecting the beam to be visible beyond the curvature. Also, a laser beam diverges and will have a beam width of 10 m over 10 km. https://flatearth.ws/laser https://eu.usatoday.com/story/news/factcheck/2022/12/07/fact-check-false-claim-laser-tests-prove-earth-flat/10821382002/
