The Mushroom Kingdom-a parallel universe or just some island in the middle of the ocean. The universe as we know it has our "physics" applied. Nothing can break these laws of physics. Right. Then one must logically assess the possibility of another interdimensional realm-shall we call it-on the very edge between our universe and total annahilation. This has the norm of space-time relativity as so on-but it also is capable of defying the laws of physics as "we" know it. So-one must think it is interdimensional. Let's forget about all that crud in the movie SMB. Then that means the Mushroom Kingdom is in a higher state of being. A mulitdimensional realm perhaps. Things may have some of our applied physics otherwise this universe would collapse in on itself causing a molecular conversion into nothing. Let's just say that as we go along our daily course of life that the Mushroom Kingdom has no idea that we exist until Mario and Luigi bust into their multidimensional realm turning enemies into coins and such. Basically the koopas have taken over the realm. A sudden burst in tachyons-a theoratical quirk or elemntary particle that can somehow defy Einstein's E=MC2 without expanding infetessimally-could be responsible for the physical science as they understand it. Mario's reason for jumping six times his own height may be due to the sudden changes to the physical world around him-remember-he is in a multidimensional realm. Another possibility is that the Mushroom Kingdom is an anti-matter galaxy. Antimatter is said to fall up-of course we can't proove that yet because if and when antimatter and normal matter come in contact with one another it results in a full molecular conversion to pure energy in mutual annhilation. so the entire Mushroom World may be upside down to us. this may accout for the jumping Mario does. If the field around him reacts with the multidimensional realm in some way-well , he could jump up to 75 feet in the air as well. You see, i think Mario was teleported into the Mushroom Kingdom other than the Mushroom Kingdom being in our own universe. The warp pipes must use our space-time fabric if they want to prevent causing their own universe to collapse in on itself. So a stray warp pipe "signal" could have instaneously transported Mario into their own unvierse as fragile as their space-time fabric is because they used ours. Which means the warp pipes aren't really hand-built at all-it means that the warp pipe is a naturally occuring phenomena caused by the formation of their Mulitdimensional universe. How to transport Mario without compressing him into another thin membrane of infinite time is beyond our knowledge-since he was in our gravity and if one ever is instantaneously transported they must travel faster than the speed of light-186282.7 miles per second. This data may be conclusive and change the way one views our universe. Just maybe.
