Perspective

U need to see this, it`s called The Double-Slit Experiment.

Here’s the kicker: The insertion of the interferometer took only 40 nanoseconds (ns) while it would take 160 ns  for the information about the configuration to travel from the interferometer to reach the photon before it entered the slits. This means in order for the photon to “know” if it was being watched, that information would have to travel at 4 times the speed of light, which is impossible 
Of course there is a lot more to this :D



If you want further explanations here is a 30min video that goes into more detail.

  1. That is some very interesting experiment. I wonder if there will be more use of this in future.

  2. lol where do you get this stuff?

  3. That video blew my mind...
    Maybe the electron is a little spaceship...with a little alien inside it...and he's just trolling us

  4. If it;s impossible then how in the sam hell is it done!!

  5. Finally something faster than the speed of light ! I still think they messed up somewhere :)

  6. lol informations > speed of light :D

  7. quantum theory says that electrons can be in two places at the same time.

    man... i was actually trying to give a proper explanation here but it involves a lot of theory and i only vaguely understand most of them. if you guys are really interested about this topic, try reading some book about quantum entanglement, multiverse theory, and string theory. oh yeah, it also involves the schroedinger's cat! -___-

    btw, this thing also suggest that one day, you might wake and found yourself at the other side of the planet. lol

  8. Heh, I'm having an exam about diffraction tomorrow, this kinda helps me get motivated to know more. But yeah, you can't help but wonder if they've done something wrong in there.

    Science really gets mindboggling once you get down to that incredibly small level, a lot of things don't seem to make sense down there!

  9. And this is how black holes are formed!

  10. That video is fricking awesome and very interesting! Cool post

  11. can i use this to kill zombies?

  12. did any information actually travel?

    ReplyDelete
  13. only takes 40ns huh.. how can u measure this stuff lol

    ReplyDelete
  14. This is awesome, keep it up !

  15. Uh... The creators of that Dr. Quantum video are from some cult. So while the Double Slit experiment is indeed real, the rest of the shit they say are, well, bullshit.

  16. wow this is extremely interesting o_o mind blowing stuff

  17. fuck yea. you have rekindled my long lost love with physics.

  18. dam quantum mechanics, make my brain hurt

    ReplyDelete
  19. dang man you're always posting interesting stuff! thanks!

    ReplyDelete
  20. Yep, there it goes, my brain stopped. May need to dumb it down later lol.

  21. Holy smokes. That was an incredibly intriguing video. And it was very easy to follow. I'm going to watch the full one now because it was so interesting. For anyone of these choads here whose brain it made hurt, they probably didn't watch it. So there. I said it.

  22. i wish my science class was as cool as this :P

  23. With the speed of light being the (as far as I know, I'm not too educated on this science thingamajig) speed of light, then how can it possibly travel four times that speed, unless there's some pretty flawed theories we're currently using?

  24. wow, I've bookmarked that 30 min video.. I'll watch it later on tonight

    ReplyDelete
  25. that video is really intriguing... I wonder how it was all originally figured out

    ReplyDelete
  26. wow, I never understood quantum mechanics like I do now

    ReplyDelete
  27. dammit, I wish I had YouTube resources available to me when I was in high school... it would have made understanding these concepts much easier

  28. haha our chem prof showed us this in one of our lectures...
