Prof JOHN G. RARITY - "TELEPORTATION & TIME TRAVEL WITH PHOTONS
Can you travel in time - the famous grandfather paradox states that its impossible because any change you cause in the past will necessarily change the future. It turns out that some of the experiments we can do with particles of light (photons) may shed light on this paradox. John Rarity will explain the wave and particle like nature of light and various quantum paradoxes that result. Key to the time travel example is the exploitation of strong correlations between photons (entanglement) which allows one to 'teleport' the quantum property of one photon to another some distance away. This concept can be extended to teleportation back in time and used to illustrate the grandfather paradox. This may all sound quite bizarre but John's aim (challenge) is to make this understandable to the layman in the lecture.

  • @estesoyojajaja hollowood physics for you non those things are important to teleportation

    time scale was originally derived from a sun dial which is measurement of angle of shadow cast from the sun

    to be exact are 24 hour clock system is not absolute considering the 29th of february only exists once every 4 years

    not only that but light speed(186,282 miles per second) is un important to a time traveller because with out the constant of 3.1415926535897932384626433832­79~ it wouldn't exist at all

  • @okuma0kuma ...and, how did Doc calculate the time exactly when Martin has to star the car to run to 80 mph in movie 1? He sayd that he calculate the velocity of the car and the time the thunder was gonna struck and the wind factor or something like that, but do you know the formule of that?

  • @okuma0kuma ok. But in Back to the future, i mean, you have to admit....Is a classic. And , what is that event in your early life? Probably you died and know are back. May be, you have reencarnate in the body of someone else.

  • @estesoyojajaja that right doc reads martys note after ripping it up (linear),! then (non linear event) he repairs the note and rebuilds a new machine into the future after movie 2

    doc go into the passed marry a women who died in carriage accident ,re invent new steam powered time machine and travel back to future with his new family creating a new lineage which ! has no affect of linear paths of people in future

  • @estesoyojajaja na im average guy who seeks answers to an event in my early life ,yep back to future shows a time line along linear path ,but duration of motion (aka time and space) is relative (non linear) although movie is a classic the rules of the paradox are mixed up,um i guess butterfly affect and donny darko rules are more real

    butter fly effect only the guy's mind (memory ! particles) is transported back in time

    donny darko is similar main character even returns in sequel ! after death

  • @okuma0kuma the las thing, if Doc was living in 1885, how can he be living in 1955 ?

  • @okuma0kuma Are you some kind of physicist? If it is so, i just have to tel;l ta something... YOU ROCK MAN !!!! I mean, it is cool. I love all this stuff, paradox, time travel, multiverses, all that. By the way, in the film Back to the future, you can find a lot of that, ex : when Martin is in 1955, with Doc. Brown, and then find out Martin that Doc was killed in 1885, how it is possible that Doc is living in 1955 if he was killed in 1885 ?

  • @estesoyojajaja if what you said was true then wouldnt that simply mean the device you are thinking of is actually cloning the person and not transporting the person instead ,sheldon cooper logic fails muhahaha

    i think real life teleportation displaces the particles ,there no recording uploading or decompiling of a matrix required ,shows like matrix ,farescape and startrek are misleading were as stargate ,charlie jade and fringe are much closer to reality but still fiction is still fiction haha

  • @okuma0kuma that is true, but assuming a devise is invented wich identify the quantum mater of an individual in one location and transmitying that patern to a distan location for assembly, you would not just being transportying the individuo, you will be destroying the individuo and recreatying him in another. Sheldon Cooper, The big bang theory.

  • @estesoyojajaja funny but true .. yes syncing the swapping and merging of volumetric masses will be the main problem

    engineers can teleport individual particles but on greater density there will be a volume of space preoccupied to were the destination of teleported mas will go ,all the particles in that empty space will instantly merge with the teleported mass ,so logical theory would be swapping the destinations simultaneously ,but if not sync the teleported mass will be partially decimated
