Rather than give the mathematical physics point of view I was trying to give more of an "in practice" and intuitive point of view: a physicist would not normally try to apply the Lorentz transformation to a massless object, knowing what would happen. | |
| Jun 24, 2016 at 0:05 | comment | added | Dan Piponi | The Lorentz transformation describes a change of coordinates when you switch from one coordinate system to another. It doesn't make sense to say it applies to "objects with nonzero mass". It's like saying that the formula for converting from centigrade to degrees doesn't apply to heavy objects. And it doesn't require any energy to change coordinate system. | |
