Natural Science Forum / Physics / General Physics / July 2008The Shallow discussion of reality in 2 NGs
All discussions in this NG concerning a TOE are centered on subjects such as inertia, gravity, and the unification of the known forces. Yet modern physics indicates that all these topics concern phenomena that are at least secondary or further removed from the true basics of reality. It's as if one group of ants is discussing the basics of a dropped ice cream cone while another is discussing why a dead beatle is basic. Better questions to ask are "What is a dimension?", "Why does math indicate there are three or eleven or any other number of dimensions?" "Why is there eternal inflation?" Or how about this question, "Of what is a cubic centimeter of a black hole composed?" Quarks? P.S. Despite what you may think the title of this post does not indicate it is merely a troll. >All discussions in this NG concerning a TOE are centered on subjects >such as inertia, gravity, and the unification of the known forces.

From an earlier post of mine, here are similar ones I proposed. 1) Why only 3 spatial dimensions? 2) What sets the direction of time? 3) What happened to the anti-matter? 4) Is the universe finite or infinite? 5) Is there more than one universe? 6) Are there Laws of Physics which completely explain everything?

Oh wait... I checked out http://tinyurl.com/4uo45p and clearly you are.

Entropy gain. May also have to do with 3) > 3) What happened to the anti-matter? CP symmetry violation. > 4) Is the universe finite or infinite? Finite. > 5) Is there more than one universe? yes, but it doesn't matter, since we can't see anything outside our own universe. > 6) Are there Laws of Physics which completely explain everything? in theory, yes. In praxis we will never be able to predict the course of a snooker ball after 5 collisions (or anything of similar complexity).

To avoid certain anomalies in the theory, so that it retains even a theoretical chance for meaningful calculations. > "Why is there eternal inflation?" This one is of a different quality; because otherwise the universe would have collapsed too early for us to evolve and ask this question. > Or how about this question, "Of what is a cubic centimeter of a black > hole composed?" Trick question. What kind of ruler do you use to define this cubic centimeter? > Quarks? Could be anything. The galactic core black hole only has a density of ~1 (IIRC), so it could even be normal matter. It doesn't matter though, since all you see from the outside is mass, charge and angular momentum.
