Interesting question to think about. We know that there are lots of comet bodies in the Oort cloud and we know that even in the near absolute zero temperatures evaporation does take place. Comets are usually covered in dust, which slows down this evaporation, but let's consider clear body...

Does anybody can propose a good book on classification of the complex simple Lie algebras. I know that they fall into several simple (An, Bn, Cn, Dn) and exceptional groups (E, F, G), but I find only a pieces of information about these algebras. Also, they could be represented by...

Good. Please, understand me correctly, that was not directed to you... That was just an example of where misunderstanding could lead us.. Have fun :)

Basically, your argument is understandable. Some pseudoscientists use this kind of a argument to descredit math (for instance, they said that there are no right triangles in the real world). I had a hot discussions in the past and I might say that it was very difficult to proof that math is what...

Think about Pi in little bit other way. Pi is basically division. I think you familiar with real numbers which is infinite field. So when you divide a circle's circumference to its diameter then you will divide it infinitely, producing new and new digits to the final Pi number. So precision is...

I bought this book almost a year ago and find it very amusing and educative. However, I thought that problem in me that I constantly return back in chapters and clarify thing over and over again (should be mentioned that understanding increasing with each turn), but now I see, that I am not the...

Actually, wormholes are solutions of equations of GR, but they could be created only when matter of negative energy is introduced. However, so far nobody saw or created matter with negative energy. Perhaps Dark Energy could help, so here we need to understand particle and high energy physics...

Do not be confused with space shape/curvature. Some believe that if you go in Physical world on a staight line and if space is positively curved then it would be like following a closed line on a shpere. But if space has zero curvature (flat), then line will never end - infinity. According to...

Quick answer: Pi is an ideal mathematical entity not from 'our world' in some sence. Some philosophers said that there are Physical World, Mental World and Platonic World. Platonics entities are ideals like infinities, right triangles, real numbers and they proved useful in explaining of...

Interesting topic, but I think the answer in classical manner to this question will be profound anyway and semiscientific. Remember that "matter" could be bosonic or fermionic, so that Bosons do not obey Pauli exclusion principle and do not occupy space exclusively, but Fermions do. So bosons...
