Get ready to re-think your ideas of reality. Join UCSD physicist Kim Griest as he takes you on a fascinating excursion, addressing some of the massive efforts and tantalizing bits of evidence which suggest that what goes on in empty space determines the properties of the three-dimensional existence we know and love, and discusses how that reality may be but the wiggling of strings from other dimensions.

  • He's just hiding from radiation 27 and magnetism 28. If the universe gets to the end of its lifespan, the dillusion will break down and we will move into pure logic realm. The rays of true and false will become so weak, that we will be in real truth. So, you have this little table that says why, wow. So, all boses buy bannana's all employee's slip on bannannas...tables and tables, its the same answer, but what about higgs? Don't assume that its just all math and extrapolation, brain power.

  • @piperadio

    The Higgs field causes particles WITH mass to slow down.

  • How can anything like space is so empty ...so "full of vacume" expands? It is like a ballon expand because it has no air? LOL

  • I must be an idiot: They said massless particles move at speed of light. But for the spaceship to fly at speed of light it will be infinitely dense as the result. What am i missing here? please explain

  • Logic question: if the Higgs field causes massless particles to slow down, why doesn't it effect photons?

  • @arabjin666

    Ok, I believe in god, she's amazing!

  • Great videos UCtelevision! Thanks prof.!

  • Thanks for this lecture. This is one of the best I've viewed on the topic. He has the ability to take difficult concepts and explain them in a clear, easy to understand way for the layperson. I look forward to whatever they discover with the Hadron Collider, and would like to see more interest in it in the United States. We get very little news coverage of it.

  • @morow109 If true, one fortunate thing is that it will be soon discovered to not exist, and we wont just be wondering forever. So cheer up :)
