It wouldn't be infinite energy, teleporting would require much more energy than having something fall,(reply>), +joao sturza<br>Energy is equivalent to mass, and mass bends space( causes gravity ). As the object keeps going faster and faster, its relative energy/mass increases as it approaches the speed of light. At some point, it becomes so massive that the barycenter of the earth-bottle-portal-of-doom system moves inside the bottle, thus it can't accelerate any more.,(reply>), @caleb kirschbaum it will keep acelerating  as long at is going untill reaching 99.999% ligt speed and then keep going what will happen when it can't acelerate anymore without passing the speed of light?,(reply>), @joao sturza Well, it can't reach the speed of light to start with. It will take an infinite amount of energy to get to c.,(reply>), Well he says "if you can break the rules of thermodynamics",(reply>), @caleb kirschbaum what would happen when it hit the speed of light ,and kept acelerating
