The Size of a String You might consider that PBS as good as it is tends to do what we term Popular Science shows. Popular Science at times makes generalized statements that may or may not be fully accurate when it comes to trying to work things out by math. I would suggest that the comment...

From a brane world perspective some of this is to be expected. As brane tension has local effects on gravitation and also the local vacuum state. Following a normalized Schrodinger equation the quantum spectrem should display aspects of whatever eventual model is found to be correct. A...

Now that is 100% the truth.

Why is it that when a person tells you there's over a billion stars in the universe you believe them, but if someone tells you there's wet paint somewhere, you have to touch it? Basically, that's actually a decent question. Part of the problem is our own 3 dimensional locked sences and...

Jack Sarfatti, even though he follows Bohm's pilot wave model, tends to at least by implcation support such. Personally, while I believe quantum effects do have implications for the subject of consciousness I tend to rather like avoiding them in general discussions of physics. However...

I think in general you do, though we might argue where exactly to start there. Here is the real crux of the problem somewhat reflective of Kant's own views also: We have synthetic a priori knowledge of the spatial and temporal forms of outer and inner experience, grounded in our own pure...

The most shocking outgrowth of the physics of branes has been the Maldacena conjecture. This conjecture states that M-theory subject to particular boundary conditions is in fact equivalent to some supersymmetric Yang-Mills theory on a manifold of smaller dimension. One example is the so-called...

Parden the diagrams. They did not translate right to here. But Feynman diagrams abound for you to get the idea from.

One aspect of what strings are made of goes back to Feynman diagrams. Feynman diagrams are graphs that describe processes where particles interact, like this: \ / Two particles come in, \ / -----...

Now you've hit the real crux of the ultimate question being asked by Science, "Where did it all come from?". Most of us suspect Nature is its own origin of itself. Now, that could imply that some form of space-time, or at least its primary building blocks have always been around(ala Hawking's...

No, problem. Been mostly buzy on the outside lately and with the holiday and all.

Bits and fragments of space-time, as Smolin tends to term them. Together they form space-time.

Anthropic Principle There are several mysteries about the Universe: Horizon problem Flatness problem Matter/Anti-matter asymmetry Cosmological constant to name a few. This makes it appear as though we live in a special universe. Some quantities seem to be highly improbable values...

The Anthropic principle argument raises problems generally because it tends to sound like invoking a religious kind of solution. One reference to this is found at "The Teleological Argument and the Anthropic Principle." In The Logic of Rational Theism: Exploratory Essays, pp. 127-153. Edited...
