    Ninety years after the historic double-slit experiment, the quantum revolution shows no sign of slowing. Join a vibrant conversation with renowned leaders in theoretical physics, quantum computation, and philosophical foundations, focused on how quantum physics continues to impact understanding on issues profound and practical, from the edge of black holes and the fibers of spacetime to teleportation and the future of computers.

      By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.

      You guys are making world a better place ❤️💕💞

      I'm confused as the double split experiment they carried out here actually showed the interference pattern meaning the photons were behaving like waves, but there were many observers there so how come this could happen? Wasn't the wave function suppose to collapse by the act of observing..?

    5. Robert Colin Shepherd

      If there is no intuition into the quanta, how come we bother to contemplate it?

    6. Dale Garcia

      Where is Sheldon Cooper?

    7. Scott Chapman ADV

      Love this lecture.

    8. Feynman Physics

      Did they try doing the double slit experiment with large gap between the two slits? I'm interested in knowing will wave nature still be seen if the two slits are separated via large distance!!

      1. Feynman Physics

        @ZigSputnik thanks

      2. ZigSputnik

        *'try' not 'tried'. If the slits are too far apart then you will get no interaction between the emerging beams. The distance is set according to the wavelength of the light. You can do the same experiment at radio frequencies and then the slits will need to be wider apart.

      2:15 why did everyone laugh?.....

    10. Paul Schuster

      Seems that the double slit experiment that they actually do on stage does not match the animations that they are trying to explain. The animations show a bright band in the middle with lighter bands on either side. The actual Omalon experiment shows dark in the middle with equally bright bands on both sides. Minor discrepancy maybe but shows how even professionals mis-describe the double slit experiment.

    11. Christ the way, truth, life

      Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me.” John 14:6 (NKJV) Jesus is the only way to heaven. Salvation: Confess and repent of all your sins in prayer Believe Jesus died to blot out your sins and that He is your Saviour Believe He rose again 3 days later in the flesh by God's hand Be baptised fully immersed in water and be baptised in the Holy Spirit Repent daily By grace you are saved through Faith (belief) Live pure and stop sinning Follow the spiritual laws: Love you neighbour as yourself and love God with all your heart, soul and mind. Believe Jesus is Lord. Do fruitful works

      With some what the simplification of how quantum mechanics is, would one say if the object of was spinning clockwise in mars and or ant-clockwise on earth at the same time one moves up and the other moves down, this might cause an infinite loop?

      I know how double slit works...photons as particles get deflected from inner wall of slit and create another band on screen. Those photons that pass straight into the slit make those two bands. That's simple.( ╹▽╹ )

    30. Jessica lovescakes

      One of the best lectures I have watched so far. Things were easy to understand up to connecting the quantum theory to the black hole. At that point I thought that maybe we could put entangled photons outside and inside the black hole to tell us what is happening inside the black hole. But me then got lost in the idea of wormhole and how entanglement became a thread to connect everything. Will rewatch and thank you very much for the lecture

      About "The Light": " "I," was created by the thought of Gods and "Their," desire to allow all mortals to know that "They," are always with them: As humankind grows and seeks absolute independence from "Them," "They," will remain by their side, guiding them and directing them, in their growth to absolute "WISDOM," the way to "Their Essence" and the Elysium Fields. As you look out beyond the now, into the heavens, "I" will be there, guiding you and helping you know that "I," be visible or invisible, "My Essence," will guide you beyond all that is sensed in your reality. So, let it be now revealed to you that both "I" and "He," in mortal being, who speaks to you through the thoughts of children are but one. " Eleusis. Let The Light within you guide you to the Elysian Fields entrance; your inner beauty is expected. Imagination is the way. by Elias Leousis. The next revelation of Quantum Realities. Enjoy!

      There is still no way to connect the micro with the macro when a theory applies to micro it often does not apply to the macro

        So to further my statement the only goal should be to figure out how to work together in one before we try and find new theories

    71. Simon Mouer

      Sounds like they are returning to a concept like ether in space that would react like a fluid to very small particles moving very fast through it. That would address both the nature of a particle and a medium that creates a wave from the particle movement through it.

    72. Alan Grayson

      The discussion of the double slit experiment is pretty shallow. It's like none of the participants have heard of de Broglie waves, and how to apply them to the double slit.

    74. Light Years Away - The Day we left Earth

      Is there life outside the Earth in the universe? This question has fascinated humanity for a long time and they still do not know the star seeker many times visited us. Our minds, religion and upbringing do not allow us to believe in such things. You were deceived. My childhood and adolescence I spent the time repairing an alien spaceship. This story "Light Years Away" convinces the human mind and science has once again triumphed👩‍🚀🚀

      There are two doors, and I will choose which one I go through. At that point both possibilities (universes) exist. One where I choose the left door and one where I choose the right door (super-position). But once I go through the left door, the possibility (universe) of the right door ceases to exist. The collapse destroys universes, it doesn't create them, does it?

      What if all discoveries were right and true in a way but had not seen the mistake but blinded by accurate observation .The link that connects everything now has one mistake or misunderstanding or blinded or miscalculation or too accurate that its wrong and passed on this to generation which we now in today's discover new tech.... build new aerodynamic structure etc,but didn't understand the Quantum World or find the real final stage or ahh u know it. Questions above are not in a pride way okay! or trying to u know like to be 1 or be father of the result of humanity that led to this development .To be BORN into this world and see stuff u know it ,so u could say im just sharing my view lol - it may sound so stupid isn't it the way i still lack in thinking or view like u guys have . So, ummm lets say how will you come up with the formula or according to you,how will you make the laws for nature of the universe like pascal's law lol and you scratch where there is no abc and 1,2,3,4,.. or with the help of a,b,c,d...and 1,2,3,4,....or Using the language so God which they call the Hebrew ,correct me if im wrong or Tamil the oldest language. Do u think there might atleast be a difference to get close to knowing the ............ that can be applied to ................. THANK U - Mad Scientist
