Why Can’t People Teleport? | WIRED
Let’s face it: No one likes to travel.
Even if they are traveling to get to a different location for vacation or traveling to work on a daily commute, no one really wants the part where they have to travel. People who say they like to travel probably mean they like it coming. That’s because going somewhere can be so much fun: seeing new things, meeting new people, getting to work earlier so you can get home early and read physics books. The actual GETTING The part is usually a drag: prepare, hurry, wait, hurry so on. Anyone who says “it’s the journey, not the destination” obviously doesn’t have to sit in traffic every day and never get stuck in the middle seat on a transatlantic flight.
Wouldn’t it be great if there was a better way to get to places? What if pwede lang SHOWS where do you want to go, without going through all the places in between?
Teleportation has been a fixture in science fiction for over 100 years. And who hasn’t imagined about closing their eyes or jumping on a machine and suddenly finding themselves where they want to be? Think of the time you can save! Your vacation can start today, and not after the 14-hour flight. We can also get to other planets more easily. Imagine sending colonists to the nearest habitat planet (Proxima Centauri b, four light-years away) without having to spend decades traveling.
But is teleportation possible? And if so, why did scientists take so long to make this true? Will it take hundreds of years to develop, or can I expect it to be an app on my phone soon? Put your phasers in stun, because we’ll focus you on the physics of teleportation.
Options for Teleportation
If your dream of teleportation is to be here one time and then in a completely different place the next moment, then we are sorry to tell you right away that it is impossible.
Unfortunately, physics has some tough rules about whatever happen immediately. Anything that happens (an effect) must have a cause, which in turn requires the transmission of information. Think about it: In order for two things to be reasonably related to each other (like you’re missing here and you’re showing up somewhere else), they need to talk to each other. And in this universe, everything, including information, has a speed limit.
Information has to travel in space like everyone else, and the fastest whatever to travel in this universe is the speed of light. In fact, the speed of light should be called “the speed of information” or “the speed of the universe.” It is cooked into relativity and the idea of cause and effect, which is at the heart of physics.
