It's odd even physics students are not proving it's a globe, despite the fact it's pretty easy and cheap to prove what's the shape with lasers

If someone wants to invent a powerful visible-light laser and point it level with the horizon to prove it either way, go for it.

But what if it were profitable to not do so? Sheep's cloths look really silly on a wolf, but not to a sheep.

If the Earth is flat, the laser should be able to strike a point equal in relative elevation anywhere on the plane.

Don't even need lasers, the issue's clearly demonstrated by propagation of radio. It's why TV/Radio towers are needed & you can directly calculate how far it will go over flat terrain.

If it's round/globe the laser should move tangentially away from the surface.
