"As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map"
- Edward Witten
About this Quote
This quote by Edward Witten is describing the truth that string theory, a branch of theoretical physics, is not able to describe why there are 3 big measurements in addition to time, and why the other measurements are tiny. This is a significant issue for string theorists, as they have yet to come up with a satisfactory description. Numerous propositions have actually been advanced to try and describe this phenomenon, but none of them have been able to supply a conclusive response. This quote highlights the problem of the issue, and the lack of progress that has actually been made in discovering a solution. It also acts as a suggestion of the intricacy of the universe, and the difficulties that researchers deal with in trying to understand it.
"One has children in the expectation of dying before them. In fact, you want to make damn sure you die before them, just as you plant a tree or build a house knowing, hoping that it will outlive you. That's how the human species has done as well as it has"
"Well, I think any time you delve into this sort of religion, politics, as you well know, you're going to, you know, touch a few nerves. I wasn't - now - and this is the honest truth"
