Most of us, our lives is limited and revolves around the normal hustle of the city, get a job, go to school and pay bills and much more. Not a single day have we stopped to ask very fundamental questions about the universe in which we live. I believe as a person with a brain and living on this earth, I have a right to stand and ask some of these fundamental questions, and I also have a right to get answers.
Now am not a physicist neither am I a mathematician but I had I a personal and vested interest in this two, because even now I believe they hold the key to at least if not most of it, shade some light on this mysterious universe. While reading; “Physics for Today and Tomorrow by Tom Duncan”. I came across a very interesting topic of quantum mechanics and so I decided to do a bit of digging. What I found on the topic is intriguing and mind blowing which left me with more questions than answers on the reality of the universe we live in.
For thousands of years scientists have been trying to unlock how the universe works, and they have done extremely well. At the fundamental level they have come up with extremely different set of laws that has redefined how the universe works from the outta space to the cities we live in, and to this effect our view of the world has shifted, thanks to these strange mysterious laws that are redefining our understanding of our reality, they are they laws of quantum mechanics.
In quantum world there is a sense in which particles don’t like to be tied down to just one location, or path. It’s almost as if objects are in more than one place at a time and that what I do here can have an immediate effect somewhere else, even when there are no people there. And here is the strangest thing of them all, if people behave like particles inside the atom, then most of the time you wouldn’t know where they are instead they could be just anywhere until you decide to look at them. You may think that quantum laws apply only to the tiniest of particles, but think about this, am made of atoms and so are you.
However the most interesting thing that caught my eyes is the idea of entanglement. This is theoretical predictions that come from quantum mechanics equations. It says that two particles can become entangled when they are close together and their properties become linked. Remarkably quantum mechanics says even if you separated those particles sending them in opposite direction they remain entangled and connected. To understand this; consider two spinning wheels, quantum mechanics states that at any particular moment at random if you choose to measure (look) at any of the wheels, and you find one is rotating in clockwise direction then, the other by default is rotating in anticlockwise direction. But at that moment before you measure (look), any one of them could be rotating in any direction. Even if the two wheels were separated by distance say one is on the moon, the other one here on earth, if one is rotating clockwise, the other is sure to be anticlockwise.
Now that said, one of the dreams of scientist has been to transport objects across distances, without crossing the distance in between in a process called teleportation, just like in star trek but is it possible in real world given the concept of entanglement? Remarkably in Canary Islands the experiments are underway for teleportation, and they are trying to teleport tiny particles called photons the particles of light. They begin by generating two entangled particles of photons in a lab, on the island of Lapalma. One particle stays on Lapalma, while the other one is transported by laser to the island of Tenerife 89miles from Lapalma. Then, the third photon is brought in, the one to teleport, and has interaction with the one entangled in Lapalma, and studies the quantum state of the two particles.
The interesting part is, the team is able to transform the one photon on the island of Tenerife with this comparison into an identical photon to the third photon because of the spooky action as they call it. It is as if the third photon was teleported without traversing the distance between.
From where I sit I look forward to future days where humans will be teleported to distant planets with this amazing entanglement of particles as we learn more about the interesting facts of quantum mechanics and our universe.
