How can we explain the Penrose Terrel effect when the observer moves ?
Hi everyone,
I recently read something about the Penrose Terrel effect, and I really can't find why the deformation should appear when the observer is in movement while the object stay still. I do understand how the deformation appears when the object is in movement but I really understand dont in the other way around.
All the examples I found about this effect always use an objet in movement but not an observer in movement
I found this really good website ( https://andrewyork.net/Math/TerrellRotation\_York.html https://andrewyork.net/Math/TerrellRotation_York.html ) which explains the phenomenon with a great geometry example, cant be clearer but as always only with the object moving. Can we expose the same logic if with just move the M point instead of the cube in the schematic?
Thank you very much in advance, I can't get this out of my mind, it would be very helpful !
PS: For now, we can just ignore the lenghtcontraction for the sake of clarity !
