| Dec 14, 2022 at 22:08 | comment | added | HTNW | I believe the correct interpretation of this statement is: "if you see some object/signal/whatever traveling at $v>c$ in some frame, then you can make a Lorentz transformation to a frame where that object arrived at its destination before leaving its source." It doesn't make sense to talk about a "Lorentz transform with $v\ge c$" because such things don't exist. | |

| Dec 14, 2022 at 21:45 | comment | added | James | @user1551817 i'm a bit uneasy too by arguments by contradiction like "if this happens then reality as we know it would unravel!!"... it's rather more soothing to have an implicit "you can't do it no matter how cunning you are" type of argument i guess? | |
| Dec 14, 2022 at 21:40 | comment | added | user1551817 | @James Yes I thought about that too, but I assumed that wasn't quite right as it doesn't explicitly show that t2 < t1. | |

| Dec 14, 2022 at 21:33 | comment | added | James | the Lorentz factor $\gamma$ blows up at v=c, for v>c it becomes imaginary, so t′ has become incalculable? | |
