C. A train flies out of the blue portal

B, but only their bellies; the portal is above most of their bodies, and their heads and ankles will get cut off for being off even the track.

A if the trolley is going slow

B if the trolley is going fast.

If it's A, then it figures to me that the blue portal would enact some force on the structure on which it's placed when the tied up people plop out

I love this comment section. Perfect balance of people actually trying to discuss and people getting pissy because their answer can be the only right one.

I don't know shit but when I try and picture it happening in my head I can only see A being correct, think Doctor Strange portals. When he moves a portal the person comes out stationary

This comment section reminds me a bit of these cringe powerscalers, discussing Saitama vs Son Goku in the comments of a YouTube video.

I think it's A because I assume a portal stitches two points in space to each other.

So if I have a surface A and B with a portal ']' in the middle A0 A1 ] A2 A3. B0 B1 [ B2 B3

A portal creates a new surface

A0 A1 ][ B2 B3

And if you move the portal the new surface changes.

A0 A1 A2 ][ B3

Speed is distance over time. When a portal moves the object that passed through the portal stays stationary. Let's say I am standing on B2. When the portal advances I find myself standing on A2 , have i moved? No the environment has changed but i am still in the same relative position with respect to the portal surface. No distance travelled so no speed.
