Light doesn’t bend, calm water is flat. CHALLENGE at a lake put a stable laser dot (firmly attached to the shore) SHOOTING onto a poster attached to a boat, k? The boat is on calm water, no waves (like early morning on a lake) If the earth is flat the laser dot will not rise above the point it was originally pointed at as the boat travels farther and farther away from the shore. If the laser rises then there is a curvature to the strait shot land/water between the boat and the laser.
Any thought on this experiment, pretty simple way to prove your theory on a lack of curvature over a large distance, hell you could sail that boat pretty far and still see a laser dot. And if the earth is flat then the laser dot will not rise above the level of where it was pointing originally.
What do you think? This would prove to me the earth is flat, as it is repeatable direct empirical evidence!
Problem?
Light bends all the time as it passes through air. That's why stars twinkle. That's why the road a mile ahead looks like water on a hot day!
How do you ensure that the laser is “parallel” to the ground and that the pointer is not adjusting the beam to contact the target thus defeating the measurement variable
A level plane, a bubble I. A tube. Making a level surface is not a difficult task, and may be done for this experiment. There are many ways to measure 90 degrees when building an experiment.
It certainly wouldn’t bend it up or down it would just be diffracted in all directions to the original vector of travel.
As for the water on pavement, this is a very different phenomenon known as a inferior mirage, the explanation of how this happens first was explained by French mathematician Pierre de Fermat, who stated that the reason the light travels along these funny lines is due to temperature being higher and air density being lower at the level of the road. Without much thought this is not applicable to proper experimental conditions such as on a calm cold night on a lake with no warm temperature gradient at the surface. You see how this mirage example and the star light diffraction example is not relatable to this experiment?
What is whrong with this experiment, criticism is encouraged, please explain yours elf. It may prove you right that the earth is flat!!!
Ok I’ll lay it out simply. 330 am on a lake a boat with a poster board facing the shore is placed. A laser pointer is pointing from a fixed height and location on the shore, the laser pointer is 5ft above the surface of the water exactly. Therefore the dot will be five feet from the water pointing onto a poster. Mark where the laser pointer is hitting the poster.
The temperature must be cold but not freezing, can’t do this on a frozen lake lol. Mainly because of the light bending effect of temperature gradients like some other smart people inquired about.
For the example with star light diffracting. Big big big difference in scale when determining if atmospheric diffraction is interfering with results from this hypothetical experiment.
I have a green laser pointer that I can see the beam clearly with, like a light saber but it looks like it just is shooting on forever.
It doesn’t seem to bend even when playing with it next to Lake Michigan, as I’ve done many times tagging kayakers and boats with Freind’s aboard. I’ve never seen my green laser pointer bend it’s direction. I’m not a expert who went to school for light physics.
I guess I don’t see how atmospheric diffraction is applicable on a small experimental scale, as it’s effect is a function of distance traveled and the only examples you offer are large scale star light diffraction. I’ve yet to see evidence that a concentrated laser beam will be diffracted to a detrimental degree at 300m
