Black holes and the Structure of Space-Time

Usual hologram: a 2d surface encodes all information about a three dimensional object In string theory, which is a theory of qua ...

... of stellar cores of GRB progenitors. This is problematic for solitary stars: • Evolutionary models of solitary massive stars show that even much weaker magnetic fields (Taylor-Spruit dynamo) result in too slow rotation – no collapsar disk (Heger et al. 2005) • Low metalicity may save the collapsar m ...

... Are they really out there? The idea of black holes is pretty exotic. We’d like to know if black holes actually exist. If they do, what are their properties? How massive? How many? At first, it seems unlikely that we could ever know. After all, if even light can’t escape from a black hole, how could ...

Introduction to Astronomy
... Special Relativity Theory • The “principle of relativity” (Galileo, Descartes) says that motion is relative: There’s no way to tell who’s really moving, so long as the motion is straight and uniform. • But electromagnetic waves are predicted (and observed) to travel at a fixed speed: 300,000 km/s. ...

... Clearing Fractions and Decimals from an equation If given a choice, most of us would rather work a problem in whole numbers rather than fractions or decimals. We’re going to look at a little gimmick that will “clear the factions” from an equations. We’re going to look at lots of examples. (It’s alwa ...

Neglecting any effect of “dark energy,” in that case the universe would keep expanding, but more and more slowly, until it reached some maximum size.
