    The new one looks so much better than that overdetailed crap, I don’t want a painting, I want an easily discernable icon. Also, I can’t believe we’re still doing Firefox so many years after its new logo debuted, especially since Thunderbird just changed their logo. In my opinion, it seems like people are just reiterating the same joke some bloke did without even looking up the why and how. And before you ask, yes I prefer the new Thunderbird logo too, it’s much more discernable.







  • The front part of the pole wouldn’t pull the back part of the pole more so than in any normal contiguous space. If you send a pole flying from the front and catch it mid-flight from the back stopping its motion, you’ll have to apply a force opposite in direction to the motion of the pole, and by Newton’s third law (every action has an equal and opposite reaction) it’s gonna pull you towards the direction it’s moving by reactionary force while decelerating.

    In the case if moving portals, it might be a bit confusing, but what it comes to teleportation through the portals, the portals are absolutely stationary the world around them moves. And in the case only one of the two portals move relative to the ground, not only does the world move relative to both portals, it also deforms in a non-euclidean manner. That is why the pole that was stationary relative to the ground suddenly started moving after coming out the portal. And yes, it would require massive amounts of energy for the portal to function like that and keep its own momentum relative to the ground after teleporting things, but tbh that’s a woe for Aperture science, not mine 🙂

    Relative to the train, and by extension the portal, the people are moving towards it at the same speed as the train relative to the ground, since the people are tied to the ground. I’m gonna work with the definition of momentum that equals it to the velocity of an object times its mass, and with the assumption that the portals conserve mass and momentum of the objects during teleportation, or with negligible losses. Having found that the momentum stays constant, and given the mass before and after teleportation is constant, the velocities relative to the portal are gonna be constant too. (p1=p2 <=> mv1=mv2 <=> v1=v2). And since the velocity of the people relative to the portal is the velocity is the train relative to the ground, and the velocity of the train relative to the ground is far bigger than the velocity of the people relative to the ground, the answer is gonna be B, where the people shoot out of the portal with great speed.

    If the people actually go into the portal and not under it that is.
