Think of a balloon. Squish the deflated balloon as where everything was. All of it started at a similar point but then the balloon started expanding and everything is moving away at an accelerated pace from each other
The battery part was durring exposition, that is where you explain weird concepts! Then why also continue with that shit excuse in the latest fucking movie. They had the chance in no. 4, they basically had a blank canvas, explain the retcon in one of the many scenes they had to explain strawberries. No they made their choice, back in the first movie, and they kept doubling down. Batteries, even though it makes no fucking sense, they made their bed. PS love the Wachowskis, I still appreciate all they have done to entertain us
B, even as the people do not have momentum, the portal does. Think of it this way, the first person coming out of the portal, let's say they are having zero speed, but he is right infront of the portal, the second person to exit will exert a force on the first person to move and create space so that the second person can be next to the portal. What speed is this second person coming through the portal, why that will be similar speed to the moving portal. Only if the second portal is moving away at a similar speed will the people experience a situation like A, but as can be seen portal A is fixed to an angled block
But which version? Or are they going to also release different versions to different people, like they did with different cinemas?
If there are 3 different jokes in 20 different areas, technically they can almost create a unique signature for over a billion digital copies making it easy to trace if you pirated your version of the movie.
Awesome for F1, wonder how reluctant the other teams still are
