Hats off to Orodruin for the thorough explanation. Greatly Appreciated :smile: My difficulty in immediately understanding the distinct differences between the outcomes expected by Bob and Alice, came from not understanding how a two boost approach (North then East) is distinctly different from...

Yes it is clear. But as expressed in my most recent post, a two step boost seems to allow for the crate's initial orientation to be as Alice assumed, but for the outcome to be as Bob predicts. It's confusing, that a two step boost would have a different outcome to a one step boost, but maybe...

To abbreviate some of the replies (somewhat excessively), Bob and Alice are not describing the same scenario, so the outcomes are different, thus problem solved. If the scenarios are different, then it has to do with differences in the crate's launch conditions, but what those differences are...

Alice and Bob form their respective opinion based on different frames of reference (Alice uses the ground and Bob uses the train), they do not know which description is valid description. All they know is that the Assassins intend to launch the crate (500mm x 500mm x 500mm) in the North East...

This is not a paradox that I've written up after 2 minutes of thought, based on a simple hunch, I've done the math. The paradox is designed and written in a way to make it as accessible as possible, in that the math is minimal within the paradox writeup itself, but is also pretty straight...

I apologise if it isn't clear what I'm looking for from this post. Bob forms an opinion based on one frame of reference and Alice forms an opinion based on another. These opinions are conflicting, hence its a paradox. The resolution will be one of the below: (a) Alice's opinion is wrong (b)...

Thanks for the animation. However, I don't understand how the shape would shift to be in this orientation. For instance, I can swap the Northbound train out for an Eastbound train going 0.5c with South facing windows of the same dimensions. The velocity and the direction of motion don't need...

If you read the paradox, it presumes that the assassins will be able to get the timing right. In the diagram of Alice's perspective, she assumes that the assassins are able to time the launch so that the South Eastern edge of the crate will be minutely North of the Southern edge of the window...

To clarify, each perspective is the same scenario, just viewed from a different frame of reference. As stated at the end of the paradox "Bob and Alice see the merits of each other’s arguments and come to the realization that either their understanding of Special Relativity is wrong or they...

I've thought about this, but I'm not sure how it will come into play and allow the box to pass through the window. I'd really appreciate you read the whole thing and provide a clear resolution if you can. Thanks

Hi Physics Forums, I've devised a thought experiment called the "Killer Crate Paradox" to put a spotlight on an issue I'm having, with regards to understanding length contraction, specifically in instances where multiple objects are observable and they have different velocities and directions...
