Correct me if I'm wrong, but if teleportation is instantaneous, then the Earth doesn't actually move at all in the time it takes to teleport, so it doesn't actually matter that the Earth is moving (unlike in time travel, where you would drop off the face of the Earth if you didn't also move in space).,(reply>), Imagine I'm a passenger in a car, and I teleport to a rest stop on the side of the road. The car is going at 60 miles per hour, so I'll have quite an uncomfortable landing if I keep my momentum.<br>Sitting at the equator, you have a lot of momentum in the direction that the Earth is spinning, momentum that you wouldn't have if you were sitting at the North Pole. The Earth's overall motion through the CMBR doesn't matter for instant teleportation that conserves momentum, but going from the equator to the North Pole in one hop will ruin your day.,(reply>), @Broken Wave assuming that some laws of thermo dynamics still apply, the energy you had when you initially teleported is conserved. so that energy needs to go somewhere or if you are teleporting from the poles you need to gain the energy,(reply>), @shieldgenerator7 You would teleport directly into the intertial reference frame though.<br>You wouldn't be bound to the momentum of where you teleported from.,(reply>), @Fresh Rock Papa-E Relative to the Earth's core. Or the sun.,(reply>), No, the Earth wouldn't move in that time, but it would still be moving after you teleported, and it would be moving faster at the equator than at the poles, so teleporting from the poles to the equator would require you to speed up a lot in order to not be hit by anything moving on the earth
