Понеже в контекста на тгв се допускат надсветлинни скорости се чудя дали е коректно да се използва лоренцово скъсяване изобщо? The expansion of the universe causes distant galaxies to recede from us faster than the speed of light, if comoving distance and cosmological time are used to calculate the speeds of these galaxies. However, in general relativity, velocity is a local notion, so velocity calculated using comoving coordinates does not have any simple relation to velocity calculated locally
