Kind: captions Language: en [Music] you have a question you have a question you got a question on the universe hello Neil hey good to see you how doing hey what's on your mind your tie where did you get it oh well I have many ties of the universe are you interested in just this one or in the whole ensemble let's start with this one this one actually came from my home institution the American Museum of Natural History it's a cosmic tie this is I am a cosmic dude so well I have a cosmic Quest sure what do you have I've been told that the universe may have as many as 11 dimensions and we only know three what do you think should I expect as many as 11 to show up you should not think of your own life experience as the limiting factor of what is possible in the universe just because we live in work and breathe in three dimensions of space one time dimension there's no law written in the sky that requires that that be all the dimensions that exist in the universe itself and when you want to fully understand how the universe works we have to have the metal to say the way I see the world may be incomplete the way the world comes to my senses May fool me I need methods and tools of science to decode the operations of nature and I've got to be ready for nature to behave in ways that not only did I not expect but may render my biological means of learning about the world obsolete wow you've given me a lot to think about I guess I'm being self-absorbed yes in three dimensions we are all self-absorbed in our own three dimensions and it's fortunately we have the tools to think outside of our three-dimensional box and we've got top people working just that well I'll think in terms of two dimensions and get a tie like yours that's great all right thanks for coming thank you see [Music]
