 Before the Big Bang: A Twin Universe? April 09, 2008 | User rating: 4.4 / 5 after 268 vote(s)
| User comments: 30
Until very recently, asking what happened at or before the Big Bang was considered by physicists to be a religious question. General relativity theory just doesn’t go there – at T=0, it spews out zeros, infinities, ... | |
The Mathematical Structure of Terrorism May 22, 2006 | User rating: 4.2 / 5 after 129 vote(s)
| No comments yet
The complex patterns of the natural world often turn out to be governed by relatively simple mathematical relationships. A seashell grows at a rate proportional to its size, resulting in a delicate spiral. The gossamer network ... | |
 Alternative theory of gravity explains large structure formation -- without dark matter December 14, 2006 | User rating: 4.4 / 5 after 189 vote(s)
| User comments: 3
In the standard theory of gravity—general relativity—dark matter plays a vital role, explaining many observations that the standard theory cannot explain by itself. But for 70 years, cosmologists have never ... | |
 Scientists interpret physics behind invisibility cloaks August 22, 2007 | User rating: 4.5 / 5 after 182 vote(s)
| No comments yet
Is a perfect invisible cloak theoretically possible? Are there certain wavelengths—such as those in the visible spectrum—that can’t be made invisible? How will using imperfect materials affect the performance ... | |
