ok theres more than one problem with portals they defy the most basic laws of physics

imagine the following scenario:

here we have the test subject trapped in the classic infinite fall portal arrangement, now imagine that in common troll physics fashion, we attach a generator to the test subject, we would have, thats right, INFINITE POWER (u jelly power companies?)

according to the law of conservation of energy this scenario is impossible since energy cannot be CREATED or destroyed

looking back into the infinite fall portal arrangement, the test subject shouldnt even be able to fall at all

to ilustrate this think of that portal arrangement as some sort of tunnel

now as you may know gravity, the force behind the test subject's falling is natural phenomenon by which physical bodies attract with a force proportional to their mass, according to Newton's law of universal gravitation, that force is equal to:

this means that there are 2 objects in this scenario, 1 of then is the test subject and the other is an object of great mass (enough to mimic earth's mass) at the end of the "tunnel", BUT WAIT the tunnel is INFINITE, which means that even if such 2nd object exists its mass must be also infinite in order to be able to have ANY effect on the test subject, such thing doesnt exist and the area between both portals is devoid of gravity

but the test subject wouldnt just float in between both portals he/she wouldnt be attracted the center of the object with the bigger mass in this scenario, the earth, he/she will be attracted to the area AROUND the portal

also that image is not funny
