In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein’s notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at the Large Hadron Collider in Geneva).

  1. I think he was talking about the hadron collider at the end of the video that discovered the god particle (Higgs Boson Particle) in 2012.

  2. Alternate dimensions differ in their surroundings. For example; a curb color of the road might be painted GREEN in one dimension, and RED in a another dimension. Furthermore, evidence of time is observable; like discoloration of the painting, and corrosion of the cement.

  3. Space is either 3 Dimensional or it's flat. It can't be both. Make up your minds. Until then, I don't believe a word you say.

  4. So that's why Antman (Marvel) can time travel in quantum realm, bc he is enough small. But he can't back to the past, he just can travel to another universe that is closest to him.

  5. I didn’t know scientists were such good salesmen. But they do need to get government funding somehow. Just conclude this string theory talk with we will be able to use the extra dimension to attack China or something and It’ll probably get funded no problem

  6. My new theory is…….what is mass? Mass=space/time * vibration.
    So gravity has always been seen as the curvature of space time. I say that mass is space time that is clumped together vibrations. There’s is no true space between objects but less vibration. Or still waters.

  7. But why do they need strings to vibrate? Why don’t they vibrate themselves? Space and matter are one in the same. It’s just that space doesn’t vibrate the same. Matter is clumped space. That’s my theory.

  8. What we must always remember is that when we find the answer to the meaningful we realize how little later we know. What makes times so special as to be one and absolute? There’s always more, let’s all work together in unity and love

  9. He very much reminds me of the revival preachers that held forth in the tent at the traveling carnival that came through our town. It's like taking a drink of water from a fire hose; it keeps coming so fast there is no way to keep up and think about even one idea that he throws out. That is exactly how rubes are conned. Bottom line: If it can't be tested it's not science. It's religion.

  10. This guy is selling hard: It's like he has been handed a pile of used Yugos and needs to move them off the lot, "Friends, for just the paltry sum of $11 down I can send you home today in this fine automobile…..". Boeing ought to grab this guy to sell the Max, if, it ever flies again. Heck, with his fervor, he could sell them even if they did not.

  11. Oh Brian, I once got to talk to you. I asked about particles and strings, and you told me that electron and photon are not composite objects, but are individual strings.
    I about melted! You don't remember that day, but i'll never forget it!
