the universe , as we know it , is a giant near-perfect vacuum , but it contains sub-atomic particles and celestial bodies. Now , theoratically , one could be converted from normal matter to energy and put into a state of interphasic flux. Supposedly , the Mushroom Kingdom in another form of co-exsisting reality , meaning that it co-exsists beside our own normal universe. The Laws of Physics may be in a state of interphasic flux themselves , like the Mushroom Kingdom , allows the warp pipes to convert one's matter , nonorganic or organic , to energy , concentrated into a focused beam and then put this matter , shall I say , into normal space-time then using that space-time to bring the individual back into the interphasic universe known as the Mushroom Kingdom. While in the normal space-time continuum , time accelearates a bit faster , so the planet itself is actually going faster in the time frame than the individual is , meaning that it would be possible tp do time-travel as well as warping the interphasic universe of the Mushroom Kingdom and teleporting to another interdimensional world. When staying in the interphasic unvierse the Mushroom Kingdom , one is just converted to light , accelerates at tremendous speed down the pipe , then back again. Who knows!
